How Long Does A Composite Roof Last?

If you want to learn more about a composite roof as an option for your home, including how long it will last, then read below for all the details.

Are you in the market for a new roof? With so many different types out there, you need to make the right decision on which one to have installed on your home. Composite roofs are a popular style of roofing, one that many home owners go with. What are they, and how long can you expect them to last?

What is a Composite Roof?

A composite roof is a type of asphalt shingle roofing. It’s called a ‘composite’ roof because it’s made up of several different materials. Usually, the shingle has a fiberglass mat at it’s core, which then coated with asphalt and mineral fillers.

The composite roof came about thanks to a ban on asbestos used in roofing. Several other different materials were tested, and fiberglass was found to be the best material to use in the shingles.

Why Use a Composite Roof on Your Home?

With lots of different options when it comes to your roof, why should you choose a composite roof? There are several benefits to them that home owners like:

Affordable. Being an asphalt shingle, composite roofing is very affordable when compared to other options. Replacing the roof on your home can get costly, fast. If you’re trying to stick to a budget, this can be a good way of reducing costs.

Fire resistance. Most composite shingles will have class 4 fire resistance, making them a great option when it comes to fire safety. They also are rated Class A in fire resistance, the same as most metal roofs. You can use these to get the fire resistance of a metal roof, without the price tag.

Can be used in place of more expensive shingles. Several different types of composite roofs have been made to mimic other styles of roof. For example, the right composite asphalt tile will stand in for a slate or wood roof. In fact, some historic preservation projects use them in place of the real thing, to reduce upkeep and restoration costs. 

More eco friendly. Home owners are always looking for ways to reduce their impact on their environment. Replacing your roof certainly isn’t the most green thing you can do with your home. A composite roof can offset that, though. Some manufacturers make their shingles to eco friendly standards, so you can make the right choice. 

How Long Does a Composite Roof Last?

This is the important question. If you have a composite roof installed on your home, how long is it going to last for? On average, a composite roof will last around 20 years. If you’re using a fiber cement shingle, that number goes up to 25 years. Some brands can even last up to 50 years.

As you can see, there are some variations depending on which style of composite roof you buy. Most home owners go with the standard year lifespan roofs as, of course, they are cheaper. They’ll still protect the home from the elements, but they will need to be totally replaced sooner.

There are some things that will affect the longevity of the roof. Firstly, you need to maintain the roof effectively in order to keep it in the best condition. If the roof is allowed to deteriorate, then it won’t last as long.

Then you’ll need to consider the weather. Rain will affect the roof over time. If there’s any cracks in the roof, they can allow water in and damage the roof prematurely. You’ll need to carry out regular checks to ensure this doesn’t happen. Snow also affects roofs, as cold weather allows shingles to expand and contract. When this happens, you can see shingles coming loose. You’ll need to check your roof after cold weather, and replace any shingles you see coming away from the roof.

If you keep an eye on your roof though, you shouldn’t have any problems with it. Proper maintenance will allow you to get the most years out of a composite roof, before it needs to be replaced.

What to Ask Yourself Before Choosing a Composite Roof

A composite roof isn’t the best roof for everybody, so you’ll need to ask yourself some questions to see if it’s the right option for you.

How long will I stay in this home? Are you expecting to move in a few years, or are you staying for the foreseeable future? If you’re going to move in a few years, then a composite roof would work well. It will fully protect your home, and you won’t have to worry about the replacement in 20 year’s time. If you’re staying for longer, you may want to go with a longer lasting roof.

What’s my budget? This is what most people consider when choosing a roof. If you choose a regular composite roof, it’s going to be much cheaper than other options. If you have more money to spend though, you may want to choose a longer lasting roofing material, such as slate.

What style do I want for my home? The style of the roofing will have to match your home, in order to fit in with it. That’s where composite tiles shine, as they can be made to mimic other styles of roofing. If you need a more expensive looking roof on a budget, then this style will work well for you.

How much upkeep can I do? How much work are you willing to do on your roof to keep it in best condition? Some roofs, like metal roofs, don’t need as much maintenance as others. Composite roofs need a little more as shingles can be pulled off by wind or damaged by rain. They’ll need to be replaced when that happens, so are you willing to do that?


That’s everything you need to know about composite tiles. They’re affordable, high quality, and you can get them in a large array of styles and colors. If you want a roof that costs less but still protects and looks great, they’re going to be the best roof for you.

Deck Coating

Urethane vs Acrylic: Your Deck Coating Resource

Maintaining a healthy deck should be just as important as maintaining the rest of your home. So when it comes to deck coatings, which one is best for your deck needs? Here’s a look at urethane vs acrylic.

Your deck is a place for entertaining and relaxing, but it’s also an investment. To start, you’ll need to pay the initial fees of having it designed and installed. From there you’ll want to spend some extra funds on keeping it maintained. One way to protect it from the usual wear and tear involves applying a protective coat or finish.

Specifically, a deck coat will safeguard against scratches, sun damage, and rotting. As you might imagine, a rotted or scratched deck can cost a lot to repair. Your best course of action is to simply apply a protective coat beforehand.

You may want to protect a brand new deck or something that’s already seen some wear. Either way, you have a variety of materials to choose from. In most cases, a professional will recommend either an urethane or acrylic blend.

So, how do you decide between urethane vs acrylic?

Deck Coating Layers

Having a deck is one of the great joys of home ownership and can facilitate the enjoyment of your space during warmer months. Just like other spaces in your home, your deck needs regular maintenance in order to prolong its lifespan and protect its condition. Outdoor deck coatings, whether urethane or acrylic, keeps your deck safe from scratches, sun damage, and moisture.

If your area is made of wood, you can forestall rotting, the material becoming brittle and falling apart. Repairing a damaged deck, or rebuilding one altogether, is very costly. Properly installed and maintained deck coatings can safeguard against this expense.

Your outdoor deck coatings will have several layers, with the top ones providing the waterproofing as well as protecting the lower sections. Usage abrasion, such as rips, holes, and/or burns, as well as constant exposure to the elements, will contribute to the maintenance needs of your deck. If you keep your area properly maintained, you will be swapping out the disappearing top layers as needed (approximately every few years), and your lower layers could potentially last a lifetime.

Urethane vs Acrylic Outdoor Deck Coatings

These two types of material coatings are among the most popular choices for property owners. The choice of one versus the other will vary depending on your unique needs, with one of the main differences being that urethane can withstand water exposure because it is solvent-based.

Acrylic coatings are water based, by contrast, so the material may break down if comes into contact with rain or water (especially important to avoid before the layer has dried). They are, however, cheaper than urethane coatings, so they are popular in places with warmer climates. Other selling points include being easy to clean and minimal odor and toxin emissions.

Urethane benefits include a longer lifespan in general and a superior toughness overall.

Choosing the right outdoor deck coatings, as well as keeping your outdoor sphere updated regularly, can be guided with the help of a professional. Making this a priority ensures you can delight in your deck for years to come.

Urethane Coatings: Pros and Cons

Urethane coatings have a few of the same advantages associated with their acrylic counterparts. For example, the material also looks glossy and emits fewer odors. That being said, this product is generally solvent-based.

This results in some different features, such as:

  • Strong resistance to traffic.
  • Toughness, flexibility, and less risk of chipping over time.
  • Less vulnerability to spotting and discoloration.
  • Ability to level out well-making it a great product for metal.
  • Ability to adhere to previous finishes.
  • No susceptibility to water damage.

As with any product, there are a few disadvantages to keep in mind.

For example, urethane coatings may:

  • Pose fire hazards.
  • Trap water during application-creating cracking or bubbling.
  • Cost more.
  • Have a plastic-like appearance, which doesn’t always look great on wood applications.

Of course, the market has a variety of urethane products to choose from. Depending on the blend, you may lose or gain some of these disadvantages. Your best course of action is to consult with a professional as you seek a material.

Acrylic Coatings: Pros and Cons

Acrylic coats are water based and among the most popular materials on the market.

A few of this coat’s advantages include:

  • Fewer odor and toxin emissions.
  • Lower price tag.
  • Easy to clean (with soap and water).
  • Good color retention.
  • Shiny and polished; great for concrete.
  • Resistant to UV damage.

Because this material is water based, applying the coating can prove tricky. If rain or water touches the deck before the coat has dried, the material may run.

Other disadvantages include:

  • Inability to hold up well in cold weather.
  • Poor bonding; shorter life span.
  • Softer finish.
  • Higher susceptibility to marks from shoes.

Because we live in a warmer climate, the disadvantages of acrylic coatings are pretty minimal. In fact, this material reigns as one of the most popular in the area.

Choosing a Product and Preparing for Application

A variety of factors will impact your ultimate decision.

You’ll need to ask yourself the following questions:

  • Am I in search of a natural-looking finish?
  • Is my deck covered?
  • What’s my deck made out of: concrete, lumber, or vinyl?
  • Is the deck low to the ground?
  • Has the surface been previously coated?

A professional can answer your questions and provide needed information. Once you decided on a product, you’ll want to prepare your deck for application.

Generally speaking, you’ll need to do the following:

  • Purchase enough of the material for two or more coats.
  • Consider refinishing the deck and repairing any damages.
  • Sand down the surface of the deck to allow for greater adherence.

Because we live in a sunnier climate, applying more than one coat is almost always a necessity. Your decking consultant can evaluate the surface of your deck. From there, he or she will determine exactly how many coats your deck needs.
