Most shingles last anywhere between 20-30 years. This may vary based on climate, region, temperature, and the type of shingles. During this blog, we will talk about the different types of asphalt shingles and how long they typically last as well. Also, we will discuss signs of a roof repair or new roof replacement and if you need a licensed roofing company to inspect your roof for repair or replacement. How long do roof shingles last? In 2020 and 2021, we will likely see premium roof shingles last 30 to 40 years, but older roof shingles will usually last 15 to 25 years. Find out more information here!


Different types of roof material and shingle types have different life expectancies. The most common type shingle, architectural asphalt shingles, usually last 15-25 years. Another popular and affordable roofing shingle, asphalt roofing three-tab shingles, last an average of 10-20 years. This type of shingle is best in mild weather. After storms and heavy winds, this type of shingle is more likely to need replacement.


Premium asphalt shingles and other commercial-grade roofing shingles last longer, usually 25-40 years. These are more resistant to high winds and more durable to inclement weather due to a more durable material and better manufacturing. These types of shingles usually have extended warranties that ensure the shingles over a certain period of time.


More uncommon roof types, such as composite and cedar shakes can last 30 years with correct maintenance and similar durability. This maintenance is often extensive and difficult. It usually includes cleaning the roof and cleaning the attic deck boards and around them.


Signs you need a roof repair or replacement

It can be difficult to know when your roof needs to be repaired or replaced. Although this does not answer the question, how long do roof shingles last, it is important to know about roof repair versus roof replacement.

Age of your roof

If your roof is approaching or has passed 20 years since it has been installed, then it may be time to replace it. You can usually tell your roof is aging by looking and seeing if it is fading in color, has curling shingles, brittle shingles, or if there are missing or compromised shingles. With a newly installed roof system in 2020 or 2021, you will likely see your roof last longer than what was we mentioned due to new roof technology and better manufacturing.

Heating and cooling the roof

When asphalt shingles are exposed to the heat and cold, they can expand and contract with varying temperatures. When this process occurs repeatedly, it can cause cracking and curling of the asphalt shingles. Shingles are designed and manufactured to go through this process repeatedly, but over time this will wear out the shingles. Sun exposure can cause fading of the shingle and make your roof appear older than it is. This also weakens the hold of the asphalt shingle to the roof and decreases the functionality of the shingle.


Weather damage

Most common weather such as rain and snow will cause your roof to wear out over the typical life expectancy of a shingle, but other uncommon weather occurrences such as heavy winds and thunderstorms can cause shingles to become loose, damage, or to displace.


Other damages caused by weather such as falling tree branches can cause detrimental damage to your roof and expensive structural damage. If a tree or branch falls on your home, make sure to call Guaranteed Roofing. We are happy to assist you through the sometimes-arduous insurance claim process.


Curled or buckled shingles

Curled or buckled shingles are a sure sign that your roof needs to be replaced. Shingles curling or buckling are usually caused by moisture in your attic pushing the shingle nails up and out of the roof’s decking. This occurrence can cause major leaks and cause more shingles to buckle and curl, so it is imperative to get this repaired immediately.


Algae growing on your roof

Algae growth is caused by bacteria chipping away at your shingles. Shingles are made to be weatherproof, but the algae destroys this feature. Lower quality shingle material used by roofers use fillers such as limestone and dolomite. The algae will eat away the filler which then decreases or completely removes the weatherproofing qualities. If these weatherproofing qualities are damaged, then water and moisture can get into your house which can cause difficult to repair structural damage.


Daylight into your attic

If you can see daylight through your attic, this is a sure sign something is missing. Daylight through roof boards will also allow water and moisture to get into your home, which can cause damage.


Leaky chimney

If there is water dripping down your chimney this means the chimney was not properly flashed. Make sure your roofing experts use the proper protective material.


Granules missing from your shingles

If you are missing granules from your shingles, this means something is wrong. To check if you are missing granules, check your gutters and around your home for a buildup of granules.


Cracked shingles

If your shingles are cracking, this means the lifetime for the shingles are probably up. This could be caused by the constant weathering of the shingles.


Can you repair your roof instead of replacing the whole roof?

This depends on the roof condition, age of the roof, and what the issue was caused by. If the issue was caused by strong winds and just a shingle was blown off, then you may be able to replace just the shingle. However, a shingle being blown off is likely due to poor installation or an aged roof. It is imperative to replace your roof before water or weather damage causes damage to your home’s structure. Structure repairs are more expensive to fix and are usually more extensive and complicated.

Even if your roof can be repaired, consider replacing your whole roof instead of repairing it. This will keep the consistency of your roof and it will be up to date with all the new shingle material. Also, if your roof is 20 years old it is most likely nearing the end of its life. If you are patching new shingles on an old roof, they will probably stand out and look unappealing. It is best to consider all options when you notice roof damage and leaking. We recommend contacting your local roofing expert to help you determine how long do roof shingles last.
