How much does a metal roof cost?


Foley roof installation servicesCost of Metal Roofing

Metal roofs are a type of roofing material made from an alloy of metals, typically copper, zinc, or some other metal. If some kind of metal roof is on your agenda for your home or business location, you’ll want to inform yourself on the metal roofing prices available today.

They are more durable than shingles and less likely to catch fire. Light-colored Metal roofing reflects heat back into the atmosphere rather than absorbing it as asphalt does. However, price is one factor that must be considered before deciding on a metal roof. The price can vary greatly depending on the type of metal used in making the roof and where you buy it from. It’s important to do your research so you know what price range you’ll be looking at and what type of metal roof you want.

Average Cost of Metal Roofing

The price of metal roofing can range from $5 to $15 per square foot, depending on the type you choose and where it’s purchased. The average price is around $5 per square foot for steel or aluminum roofs while copper costs about twice that much at an average price of almost fifty dollars a square foot.

It may be more expensive than asphalt shingles, but homeowners can expect their investment to last twice as long with metal roof price ranges starting at $5 per square foot.

A metal roof’s price will depend on the type of metal being used. Copper is usually the most expensive, but it is also one of the strongest. Aluminum is usually cheaper, but not as durable. Zinc roofs are in the middle price range and are typically the least expensive to install.

Cost of Aluminum Metal Roofs

Aluminum roofs are the second cheapest metal roof price range at around $25 per square foot. They can last up to 50 years and work well in coastal areas where there is a lot of rain or snow because they won’t rust like steel does when exposed to saltwater air. Plus the reflective nature of aluminum roofs keeps houses cooler in the summer and reduces energy costs. But, it’s important to note that aluminum roofs can be very hard to repair if there’s a hole.

The majority of aluminum panels are composed of recycled aluminum, and the by-products are recyclable once they have served as a roofing system. Aluminum is a light material that makes it simple for installers to work with.

There are further three types of aluminum roofing.

  1. Standing Seam
  2. Sheets
  3. Shingles

Standing seam metal roof cost per square foot is the most expensive and costs around $12 per square foot. They are best for areas where there are extreme weather changes because they are very flexible, but it has to be installed by professionals or you run the risk of damaging your home’s structure.

Metal roof sheet cost is the lowest will be around  $3 per square foot and $7 if you get them installed by a professional. They are very easy to install and have a low cost compared to other types of metal roofing. They come in panels that can range from  25 to 150 feet long. They are very easy for do-it-yourselfers or homeowners with some handyman experience to install, but they are not as durable and water can get between the seams which could lead to leaks.

Shingles, which cost around $9 per square foot, come in a wide range of colors and styles making it simple for homeowners to match their home’s design. They are a great choice for those who want to add curb appeal and value to their home. Shingles can last from 20-30 years if installed properly, but it’s important that homeowners have them inspected every few years by a professional so they don’t wear out too quickly. Aluminum shingles cost is relatively high compared to metal sheets.

Steel Roof Cost

Steel roofs can last from 30 to 50 years and cost around $13 per square foot. They are one of the cheapest metal roof price ranges, but they also require a lot more maintenance than other types do because they rust over time.

Types of steel metal roof

  1. Corrugated Steel
  2. Steel Shingles
  3. Standing Seam Steel

Corrugated steel roofs are the cheapest and cost around $6 per square foot installed. They come in a variety of colors, but their style is very simple so they don’t add much to your home’s curb appeal or value. The only problem with corrugated steel roofs is that they rust over time, especially near the seams, and they can be damaged by extreme weather changes. If you live in a coastal area or one that gets a lot of rain or snow then corrugated steel roofs may not be the best option for your home because it could lead to costly repairs down the road.

Steel shingles cost around $7.5 installed and come in but homeowners can expect them to last between 20-30 years. They are very easy to install and come in a variety of colors. Plus, homeowners can expect them to add value and curb appeal if they go with shingles that match their home’s exterior design or color scheme.

Standing seam steel roofs cost around $13 installed per square foot but last up to 50 years. They offer the best protection because they are very durable and can withstand extreme weather conditions. Plus, homeowners won’t have to worry about them rusting or corroding over time so there are no costly repairs down the road. These types of roofs require professional installation but do-it-yourselfers who know what they’re doing should be able to tackle this project with ease. These steel roofing prices should help you decide what it’s best for you in terms of your budget.

Copper Roof Cost

If you want something that will add value to your home and increase its curb appeal, then copper roofs are the way to go. Copper roofs are one of the more expensive metal roofing options costing around  $15 per square foot. 

While copper is a great choice for homes in coastal areas because it can withstand extreme weather changes, homeowners have to remember that the metal will oxidize and turn green after approximately 20 years. So while installation you can ask your contractor to give a clear polyurethane coat or a clear lacquer to preserve the natural new shine of your copper roof.

Homeowners who live in warm regions will appreciate that copper is a great fire-resistant material so it’s unlikely you’ll have issues with fires caused by lightning strikes or other factors.

Types of copper roofing

  1. Copper Standing Seam – cost $18 installed per square foot
  2. Corrugated Copper Sheet Metal – cost 15-20$ per square foot
  3. Copper shingles or Tiles – cost $15 installed per square foot

Copper standing seam roofs are the most expensive metal roofing option and cost around $18 installed per square foot. They come in a variety of colors, but they require professional installation because homeowners have to make sure that all bends are perfectly straight for maximum durability. These types of roofs also add value to your home if you choose copper shingles that match its exterior design or color scheme.

Copper corrugated sheet metal roofs cost around $15-$20 installed per square foot and are very easy to install because homeowners can do it themselves if they have the right tools. These types of roofs require no maintenance, will never rust over time, and can be customized in a variety of colors.

Copper shingles offer the best value because they cost around $15 installed per square foot and homeowners can expect them to last between 20-30 years. Plus, these types of roofs add a lot of curb appeal or value if you choose shingles that match your home’s exterior design or color scheme. Copper tiles offer the same benefits and cost around $15 installed per square foot.

Zinc Roofing Cost

Zinc roofing is much more popular in the commercial market thanks to its magical ability to self-heal. But homeowners can’t deny that these types of roofs look pretty amazing and add a lot of value or curb appeal if they choose one that matches their home’s exterior design or color scheme.

Zinc shingle prices vary depending on the shingle style, thickness, and manufacturer. Shingles cost between $8-10 installed per square foot. Plus, homeowners can expect them to last between 20-25 years.

Zinc standing seam roofs cost around $17 installed per square foot and are very easy to install because they require no maintenance, will never rust over time, and come in a variety of colors. it’s slightly more expensive than steel standing seams but much cheaper when compared to copper roofs. 

These types of roofs are very durable thanks to their self-healing ability, are easy to install with the right tools and knowledge, require no maintenance over time so you won’t have to spend extra money on repairs or replacements. Plus these types of roofs can last up to 50 years if they’re installed properly by experienced contractors who know what they’re doing.

Tin Roof Cost

When we say Tin roofing, we actually mean rolled steel with a coating of tin. So, it is basically galvanized steel roofing with rust protection. 

These roofs are very affordable, with the average tin roof price between $12-18 installed per square foot, and come in a variety of different colors. Plus they’re extremely durable, long-lasting (between 30-40 years), easy to install with the right tools or knowledge so you can save more money on labor costs. Tin roofing is also available in different styles like shingles, tiles, or standing seams.

Metal Roof Underlayment Costs

If you are considering metal roofing for your home, the cost of underlayment will play a big role in determining your overall costs. The average price is around $5 per square foot and different contractors have different options available. Underlay can be attached with staples or adhesives that come with the product itself or it can use the backside of the product with an adhesive layer to stick to your roof deck.

Underlay comes in two forms – synthetic and felt paper, also known as asphalt felt tar paper or roofing tar paper. The heavier the material feels like materials that are more effective at keeping out water or wind damage for metal roofs. Also, the cost of underlayment will vary depending on the type of roofing you choose.

Maintenance Cost of Metal Roofs

Metal roofs are very durable, long-lasting (up to 50 years), and require no maintenance over time so you won’t have to spend extra money on repairs or replacements. Plus these types of roofs can last up to 50 years if they’re installed properly by experienced contractors who know what they’re doing.

Despite being more expensive than other types of roofing materials, metal roofs are a great investment that can save you thousands or even tens of thousands of dollars in the long run.

Cost of Metal Roof vs Shingles

Generally speaking, metal roofs cost more than traditional shingle roofs. However, when it comes to the long-term costs and benefits of each roof type, a metal roof is usually cheaper in the end thanks to lower maintenance and repair costs (or no repairs at all).

Nowadays you can find plenty of different types of metal roofing materials from steel shingles to standing seam metal roofs. Each of these roof types has a unique set of features and benefits that homeowners should consider before making a final decision.

Conclusion – Is a Metal Roof Worth it?

Metal roofs are a great long-term, low maintenance option for homeowners who want to add value and curb appeal without breaking the bank. They can last from 30-60+ years depending on the material you choose so while metal roofing prices are high at the setup, your purchase won’t need to be replaced any time soon!  Plus, homeowners who live in areas that get a lot of rain, snow, or strong winds will appreciate the fact that metal roofs are extremely durable.

Plus, it’s important you choose a reputable contractor who knows what they’re doing so the quality of your roofing installation will last over time!

How to tell if a roof needs replacing?


Mobile roofing services

How to tell if a roof needs replacing?

A roof is one of the most important parts of your home. It protects you and your family from the elements, including rain, hail, snow, and wind.  The average life expectancy for a roof is 20 years but this varies depending on factors like material type (e.g., asphalt shingles vs slate tiles), slope angle, geographical location (e.g coastal climates are harsher than inland locations), design of roof structure (flat roofs have a lower lifespan than sloped roofs) and other variables that can affect its durability over time. A leak or hole in your roof can cause structural issues with the rest of your building so it’s important to regularly inspect it for potential problems before they become worse! If you’re not sure how to tell if a roof needs replacing, we’ve written a comprehensive guide below to help you inspect your own roof and determine if it needs replacement. Remember, you can always call us for a professional roof inspection from a roofing veteran who can inspect every element of your roof for you, and let you know what you should do. 

Page Guide

  1. Age of Roof
  2. Roof Material Type
  3. Roof Leaks
  4. Growth on Roof
  5. Damaged Flashing
  6. Cracked, Curled, Loose, or Missing Shingles
  7. Exposed Nails
  8. Damaged Surfaces
  9. Missing Granules
  10. Dark Streaks

Age of Roof

The first thing to consider when determining if your roof needs replacing is to find out how old it is.  Most roofs have a lifespan of 20 years. So if your roof is older than that, you may need to replace it. Different roofs have different lifespans on average, for example, a metal roof will last longer on average than a shingle roof.  

Roof Material

The type of roof you have installed will also determine if you need a roof replacement. Different materials last a different amount of time. Shingle roofs are the most common and come in many different varieties of shingles.  Their lifespan is contingent on the type of shingle and how it was installed. A roofing warranty is also a good indicator as to whether or not your roof needs replacing. The longer the warranty, generally means that you may need a replacement sooner rather than later. 

  • Asphalt Shingle Roofs: 22-28 years
  • Metal Roofs: 40-70 years
  • Slate Roofs: 75 to 200 years
  • Tile Roofs: 50 to 100 years
  • Rubber Roofs: 40 and 50 years
  • Wood Shakes and Cedar Shingles: 30 years

Squishy, Saggy, or Droopy Spots

When walking on your roof, notice if there are any squishy or saggy spots. When you step upon these areas, the material crushes down and does not spring back up. If there are more than one of these areas in a concentrated area, then it is probably time for a roof replacement. When your roof leaks and the underlying wood sheathing gets wet, it rots and weakens, which causes it to sag and to be squishy. As a result if you notice these squishy or droopy spots on your roof, it indicates your roof is leaking and should be replaced. 

Your Roof is Leaking

Another way to find out if you need a roof replacement is if you notice your roof leaking. It will be fairly obvious if this happens, but what may not be so obvious is where the leak is, or how big of an area is affected by it. If you notice that there are multiple places on your roof that are leaking, you might just need to replace the whole thing. If it’s just one spot and the rest of the roof is in decent condition, it’s more than possible to repair that one spot and leave the rest of the roof alone. However, with multiple leaks, it is usually advisable to replace the whole roof.

Some other signs of leaking include patches of your ceiling or walls that are wet and discolored, water stains on the ceiling or walls, mold spots due to excessive moisture, and black streaks running down your ceiling.  These black streaks are actually molded, and the presence of them is a sign that you have a leak.

There’s Growth on Your Roof

There can be five different types of growth that occur on your roof. 

1. Algae

When there is too much moisture on the roof, which causes algae to grow.  You can tell that algae is growing along your roof by its color. Algae are green, so if you see patches of green on your roof, it’s a sign that you need to clean it off before algae really start to gather. The sooner you respond to the algae growth the less damage it will do. 

2. Mold

Mold on your roof is a more serious problem than algae. Mold growth is usually on the surface of your shingles and can be black, white, brown, or gray in color. Unlike algae that sit on top of the roof, mold damages the underlying material creating weak spots that become sagging and squishy. It also destroys any granules (like gravel) on your asphalt shingles. Mold is a very serious problem that you need to respond to ASAP because replacing your roof is cheaper than replacing your roof and having to remodel your home due to water damages.

3. Moss

Moss can grow on your roof just like algae. Moss is more of a problem than algae because it not only looks bad but it coats your roof in a substance that makes it even more slippery when wet.  If you have moss, then you need to remove the moss and any growth mats before they create too dangerous conditions for anyone on your roof. 

4. Lichen

Litchen is a type of moss that grows in colder climates. Litchen can grow on your roof just like moss, algae, and mold. It is more of a problem than moss because it also coats the roof in a substance that makes it slippery when wet. This substance can potentially ruin your shingles as well as create dangerous conditions for you or your loved ones walking on the roof to clean it. 

5. Mildew

Mildew grows on your roof just like algae and mold. Mildew is more of a problem than algae because it can grow on most surfaces, including wood. It also produces an extremely unpleasant smell and stains the affected materials. If you see patches of black mildew on your roof, respond immediately to make sure it doesn’t spread and become a larger problem. Mildew will damage the underlying materials of your roof if left alone to grow.

Damaged Flashing

Damaged flashing can lead to water leaks in your roof. Flashing is the metal strips put around things like pipes and vents that make contact with your roof. If they are damaged, water can get into your roof which will eventually cause damage to the underlying materials if left untreated. Though it may be hard to identify faulty flashing at first glance, you need to look out for bent, twisted, poorly installed, cracked, or missing flashing around seams, chimneys, attic vents, and plumbing vents. Damaged flashing can result in leaks that can cost you a lot of money to repair.

Cracked, Curled, Loose, or Missing Shingles

If your shingles are cracked, curled, loose, or missing, then they can let a lot of water through the roofing barrier and into the sunroof where it causes massive damage. Damaged shingles have to be fixed or replaced as soon as possible. If your shingles are not sealed with roofing cement, then the sealant has worn off which is why they are likely cracked, curled, loose, or missing. The most important thing you need to do is replace the shingles before the water gets into your roof system and damages it. If you see damaged shingles on your roof, you are almost guaranteed to have roof leaks which could cost massive damage throughout your home or business.

Mobile roofing repairing companies

Exposed Nails

Exposed nails are a sign of roof wear and tear that you need to look out for. If your nails are sticking through the shingles, then they aren’t doing their job of holding the roof down. When you see exposed nails on your roof, you should evaluate what is going on with the nails and make sure that there’s no damage like rust or missing parts before you walk on them. Exposed nails can also cause leaking, which can lead to costly damage repairs if left in effect. If you see exposed nails, it’s a sign that leaking has already occurred in that area, and if it’s serious, you might have to replace or repair your roof. At the very least, you must correct the exposed nails ASAP.

Damaged surfaces

If your roof shingles have been severely damaged, or your metal roof has cracks or dents,  then you need to replace it ASAP. Shingles are the most visible parts of your roof system and they can show signs of aging and wear. If they look damaged, then you might need a new roofing installation. Wood roofs also have an expiration date and if left untreated, will rot and become extremely dangerous with potential leaks everywhere. Look for obvious signs of roof material wear and tear. 

Missing Granules

Missing granules is a big sign that your roof needs to be replaced.  These granules are tiny pieces of sand that coat the surface of your shingles. They protect the underlying layer from UV rays, water damage, wear and tear, and other factors. If all these are gone, it’s time to replace your roof because you no longer have protection against water damage or other elements.

There Are Dark Streaks

Dark streaks on your roof indicate that your roof is leaking. If you step outside and look at your roof in the morning, you will see dark streaks of dirt if there are water leaks on your roof system during the night because it drips down to the surface when it’s dry. These dark streaks on your roof are actually a form of algae growth, most commonly algae known as gloeocapsa magma. As previously discussed on this page, algae growth on your roof can be quite serious and indicative of more problems. Algae growth on a roof causes damage to the shingles and can cause leaks that lead to massive damage within your home.

Tile roof repair in Mobile


It’s important to know when your roof needs more than just a simple repair. A good rule of thumb is that if the damage is significant or it has been leaking for an extended period, then you need to call in professional roofers for detailed assessment and repairs.

Can you put a metal roof over shingles



Saraland commercial roofing

The short answer is yes, you can put a metal roof on top of shingles. There are some things to consider before deciding to install a new metal roof over your existing one. First, make sure that your home is structurally sound enough for additional weight. Secondly, keep in mind the different types of metal roofs and how they will be installed before deciding which type would best suit what you’re looking for in terms of durability, aesthetics, and cost-effectiveness. The cost between various types of roofs can vary based on factors like how big it has to cover or what materials are being covered. Finally, decide whether or not an area that gets lots of sunlight should have a metal roof that reflects heat away or whether it would be better to have one with insulation.

Factors to Consider Before Installation

When deciding whether to put a metal roof over shingles, there are several factors to consider.

The structural soundness of the building

A metal roof can add a significant amount of weight to your home and might even alter its structural stability. Do some research on the structure of the house to make sure that it will be able to handle the additional weight and stress during a storm. You can also ask a contractor if they can make any renovations to the structure of your home before installing additional weight.

The type of metal roof there is available for you

Different types of metal roofs vary in their cost, durability, and insulation capabilities. Do some research on these various options before making a final decision about which one will be best for you. You should also consider where your home is located and if it will be better to have a metal roof that reflects heat away or one with insulation

The cost of each metal roof

The cost of a metal roof will vary based on the size and how many materials you need. The type also affects the price, for example, steel roofs tend to be less expensive than aluminum ones. Take some time to research what kind of material will best fit your budget as well as which type is most durable if durability is a concern.

The availability of sunlight in the area you live

If there are lots of sunny areas on your property, then an aluminum roof would be best for reflecting heat away from those surfaces during summertime. If however, your property does not get much sun then it might be better to install an insulation roof.

Research the different types of metal roofs available and decide which one is best for you based on cost, durability, how big it will need to be, etc.

How to install a metal roof over existing shingles?

There are three different ways to install a metal roof. You can remove the old shingles completely, apply an approved underlayment right over the top of the existing roof, or install purlins across your current shingle roof.

Generally speaking, it is best to have a professional handle this job because there are specific procedures that need to be followed in each case.

1- Removing the old shingles

Removing the old shingles completely and starting from scratch is the best option if your existing plywood or boards underneath are in good condition. This way, when installing a new metal roof, it will be done correctly without having to worry about additional weight on any faulty or rotten boards.

2- Applying an underlayment

Applying an approved underlayment right over the old shingle roof is probably the fastest way to install a new metal roof, but it’s also not recommended by most experts because this method could cause problems during heavy rains or storms if your plywood begins to deteriorate underneath.

3- Applying purlins

The best option for installing a metal is if your old shingle roof is in good condition and you would like to save money on labor costs, then applying purlins across your current shingles might be the way to go. However, this method of installation does not provide any benefits beyond aesthetics and cost-effectiveness so it lacks durability and performance capabilities that come with other options.

What benefits can you get from Installing a metal roof over shingles?

Installing a metal roof over your existing shingles is an excellent way to increase the value of your home, while also protecting it from common weather damage. A new metal roof can last up to 50 years without needing any replacement, which will save you money in the long run. Not only does this type of roof provide great protection against inclement weather, but they are also very energy efficient! This means that even though you may have spent more money on your initial installation, you will actually see a decrease in utility bills each month. Because these roofs are so durable and attractive looking, many homeowners choose to install them as well because they add value to their homes!

Some of the benefits include:

Aesthetic appeal

Metal roofs can come in a variety and colors and provide additional insulation. They also tend to last longer than other types of roofing materials, such as asphalt shingles or wood shakes.


Metal roofs are typically very durable since they do not rot like cedar shakes or get damaged by hail like asphalt shingles. They are also stronger than other roof types and do not require much maintenance, which means you can put off repairs for longer without having to worry about leaks or damage.

Reduced energy costs

If you live in an area where it is hot during the summertime, then a metal roof will reflect the sun away from your home. This will help to reduce energy costs because it is less likely that you will need to turn on your air conditioning as much during the summer months.

Weather Resistance

Metal roofs are resistant to fire, wind, ice, and rain damage. This is a result of the durability that comes in metal roofing material choices such as steel or aluminum.

Value-added appeal

If you choose to sell your house in the future with a metal roof installed on it, then there is a good chance that you will receive more money because it will be in better condition than many of the other homes on your block.

Easy Maintenance

Metal roofs typically only require a simple wash down from time to time. This will help you save money on any professional roof cleaning services that may be necessary for other types of roofs.

How much does it cost to put a metal roof over shingles?

It is not cheap to replace a metal roof with existing shingles. The cost of putting a metal roof over an existing shingle roof will depend on the type of material you choose to use, but typically ranges from $4-$7 per square foot. This price includes the materials and installation.

The cost of a metal roof over shingles is more expensive than simply replacing the shingles. It’s important to note that putting a metal roof over existing shingles creates waterproof protection for your home, but it will not prevent leaks from coming through undiscovered damage or if water gets into the material beneath the new surface.


Should you remove shingles before installing a metal roof?


Removing shingles can be an expensive process. If your roof is in good condition, then you may want to leave the existing materials in place and install a new metal roof over it instead. You will save money this way because you do not have to remove any material before installation begins!

How long does it take for a professional contractor to install a metal roof over shingles?

It typically takes about six days to complete the process of putting on a new metal roof. However, this will depend upon how many layers are in place and if you have already removed any old materials before installation begins. It is also worth noting that most homeowners wait several days between having their old surface removed and the new roof installed to ensure that everything is dried out appropriately.

Which is better a metal roof or shingles?

It all depends upon your needs and the environment you live in. If you want a roof that is long-lasting, then metal roofs are probably better for you than asphalt shingles because they last longer. However, if you do not have enough money to put towards new installation, but need some upgrades done quickly so leaks don’t become an issue, then shingles are better for you because they cost less and can be replaced easily.

Can metal roofs handle snow?

Yes! A new roof should never have to deal with too much snow during the winter which is why it’s important to choose a material like steel or aluminum that is meant specifically for snowy climates. If you live in a region where it snows several feet each winter, then you will want to choose something that can handle the excess weight of all of the snow.

Can you put a metal roof over 3 layers of shingles?

Yes, you can install a new metal roof over three layers of shingles. However, you need to check with your contractor to see if there are any underlying issues that may lead to water damage or leaks later down the line. Additionally, you will need to check with them about how long it usually takes for roofing projects of this size and whether they have enough time in their schedule beforehand!

Are metal roofs louder than shingles?

No, metal roofs are not typically any louder than shingles. In fact, some homeowners have even noted that the addition of a new roof makes their home seem quieter because it does not allow as much outside noise to enter inside anymore!

How often do roofs need to be replaced?


A roof is one of the most important parts of a home. It protects your family, pets, and belongings from the elements such as rain, snow, and harsh sun rays. A good roof will last for decades if well maintained; however, it can start to show wear and tear much sooner than that if not properly taken care of. The lifespan of a roof depends on many factors including region (warm vs cold), type (single layer vs three layers), and age (newer roofs last longer). This blog post will give you tips on how to determine when it might be time to replace your current roof with a new one.

  3. What are the signs that your roof needs replacing
  4. How often should you replace your roof 
  5. Types of materials used in new roofs 
  6. Costs of replacement

How does a roof age and wear out?

Roofs are complex components in buildings, consisting of multiple layers and sections. Due to the environmental conditions, they are exposed to, such as heat, rain, wind, and pollution their age mainly depends on how well these have been treated during their service life. The following factors can accelerate this process:

The weather conditions of the respective roof region play a role in the life expectancy of roofs. The more negative standardized climatic data (Munich Re) is taken into consideration, the shorter the service life of roofs will be expected. Another factor to consider is that heat and ultraviolet radiation weaken most materials over time and will lead to natural deterioration.

Why do roofs need to be replaced?

Roofs have a limited lifetime, after which they need to be replaced. In general, the roof replacement market is growing due to two reasons:

The expected life cycle of roofs is becoming shorter.

Once the average household has to replace their roof, they will opt for a quality product made of better materials than in the past. Replacement roofs are significantly more energy-efficient than old roofs and contribute to reducing heating costs, thus offsetting higher material costs.

What are the signs that your roof needs replacing?

The primary signs that your roof needs replacing are:

  • Leaks, which need to be fixed immediately. The matter is not simply one of repairing the leak but often of correcting extensive damage to plaster or ceilings below the roof if the water has caused rot.    
  • Worn out and broken gutters, which need to be replaced due to water damage.
  • Discoloration or mold on your ceilings or walls, especially if the color is unusual for that room and may indicate dampness. This confirms a roof leak and probably needs repair sooner than later.
  • Rusting of metal elements.
  • Faded or peeling paint on the underside of roof sections (in case you can see these beneath your shingles).
  • Loose or missing shingles, which may indicate deterioration of the underlying surface. Note that even if shingles are not loose, they may be deteriorating due to age

How often should you replace your roof?

The actual life expectancy of roofs is difficult to estimate. The following conditions have to be taken into account:

The climate zone in which the building is located; it plays a crucial role in determining the expected service life. Atmospheric pollution and weather conditions strongly impact on roof quality and material deterioration, especially on gravel roofs.

It also heavily depends on materials. To give an example: slate roofs have a longer life expectancy than asphalt tiles. Metal roofs or roofs that are made of metal and wood (like the Swiss Chalet) last much longer than other roof types because they resist extreme weather conditions much better. This makes it difficult to give general advice as to when a roof needs to be replaced, however, given regular weather conditions and proper installation and maintenance, the following common roof types should last in the below ranges.

  1. Asphalt Shingle Roofs: 22-28 years
  2. Metal Roofs: 40-70 years
  3. Slate Roofs: 75 to 200 years
  4. Tile Roofs: 50 to 100 years
  5. Rubber Roofs: 40 and 50 years
  6. Wood Shakes and Cedar Shingles: 30 years

In addition, the following aspects play a role:

Regular maintenance of your roof from the outset can considerably reduce its service life. This includes sealing of joints and fixing of leaks immediately as well as inspection for damage regularly. In areas with harsh weather conditions, such as the Gulf Coast and hurricanes. Or tornadoes in tornado alley. Harsh weather can cause more damage to roofs of all types. A new roof is only covered by warranty for a limited time after installation, often 20-25 years. This means that you will have to pay the full cost of your replacement on any damages or deterioration during this period.

Types of materials used in new roofs

Roofs currently come in a variety of types and materials:

Asphalt shingles: These roofs are generally the most affordable and can last for more than 20 years if properly installed. They require less maintenance than other roof materials, which is generally inexpensive. However, during heavy rains, they can deteriorate more quickly than other common

  1. Metal Roofs: Made from aluminum or steel, metal roofs can be installed in a variety of colors. They last through the years and require little maintenance. However, if your home is located in an area that sees extreme weather conditions, such as hurricanes or tornadoes, then you may need to opt for an upgraded material that is more wind and water-resistant
  2. Slate Roofs: Made of natural stone, these roofs are long-term investments. Installed by hand, they can last for more than 70 years and require little maintenance. The downside is that they are expensive to install and repair due to the impact of weather.
  3. Tile Roofs: These roofs come in a variety of styles and finishes to fit any home or building design. They are durable, waterproof and require little maintenance aside from regular cleaning. However, they can be expensive to install.
  4. Rubber Roofs: These roofs are made of recycled rubber tires that are cut into various geometric shapes. They require minimal maintenance aside from occasional scrubbing with soap and water but do not come in as many colors or design styles as the other types previously mentioned.
  5. Wood Shakes and Cedar Shingles: These roof types are often made from cedar and come in a variety of styles. The downside is that they require more upkeep than other materials, including regular cleaning and sealing to protect against damage from the elements. The benefits of wood shakes and cedar shingles are that they add a rustic look to your home and can last for up to 30 years. However, because of their natural material, they are susceptible to rotting if not properly maintained

How much does a new roof cost?

Replacing your roof is getting to be a very common project for homeowners. There are many reasons why this process has become so popular. When you think about it, some roofs can last up to fifty years, maybe even longer. That’s practically half of the average person’s life expectancy! With that kind of time on them, it is no wonder that they can be as expensive as they are.

As roofs get older, they can begin to disintegrate and become damaged. The cost of repairing a roof is usually many times more expensive than the cost of replacement. There are several factors that contribute to how often a homeowner should have their roof replaced. The first is the material. This will determine how long a roof lasts during its lifespan. The second factor, weather conditions, does not affect longevity but can contribute to how often you need to replace your roof.

Shingle Roofs

Shingle Roofs cost less than other material roofs but need replacement more often. Asphalt shingles are the most common type of roofing used in the country. These roofs have an average lifespan ranging from 15 to 20 years depending on which part of the country you live in. One drawback is that they are not very water-resistant. If you live in an area where it rains often, your shingles may need to be replaced more frequently. Another downside to asphalt shingles is that they are not very durable. One big wind gust can cause your shingles to be ripped off of your roof entirely, exposing the naked asphalt to cold winds or scorching sun and causing even more damage. The average cost of a shingle roof in the United States is between $5,000 and $12,000.

Metal Roofs

Metal Roofs are more expensive but need replacement less often. Costing anywhere from three to five times more than a normal asphalt roof, metal roofs are built to last. Metal roofs have a lifespan of 50 to 70 years depending on the quality of the materials used and the weather conditions in which you live. One main benefit is that metal does not hold onto moisture, making them resistant to water damage as well as fungus. Metal roof installation costs average from $9,545 to $43,819 in the United States, but that depends heavily on the specific type of metal roof you choose and the size of the building being roofed.

Slate Roofs

Slate roofs are also expensive material roofs, but need replacement the least. Slate roofs are made of natural stone which makes them very durable and long-lasting. These roofs have an average lifespan of 100 years or more depending on how well the roof is maintained after installation. One disadvantage to slate roofs is that they can be very heavy, causing structural damage if not installed on a building that can safely support and fully hold their tremendous weight. On average, slate roofs can cost between 11,550 to $44,000 but there are requirements in the type of framing to safely support them that increase associated costs as well.

Rubber Roofs

Rubber roofs can be made out of recycled tires and typically last 30 years. Rubber roofs come in a huge variety of colors and different types of rubber form tiles or shingles like asphalt or metal can make them very durable. They are also built to withstand all kinds of weather conditions including snow, rain, sun, etc. Because this roof is made from rec

Wood Shakes and Cedar Shingles

This kind of roof is another great choice if you like the rustic, old-fashioned look as it comes in many different shapes and textures to create a beautiful finish. When you put this type of shingle on your house, you’re not only improving your home’s appearance, but you are also adding more insulation value.

The average cost of wood shakes and cedar shingles roof is about $19,000 in the United States.


Roofs are a big investment and their longevity depends on many factors. A roof’s lifespan can be increased with the use of certain materials, proper installation procedures, and regular maintenance.
