What is the Typical Life Expectancy of Roofs?

There are quite a few aspects that can directly impact life expectancy of a roof. From the local weather to the material chosen for the shingles. Consistent upkeep will help your roof greatly by prolonging its lifespan. To entirely understand exactly how long your roof is designed to last, you must investigate the material of your shingles.

Wood Shingles

Wood shingles generally see lifetimes of 30 years. But, if a roof is to last for this long, annual inspections and maintenance are both necessary requirements. Despite this, wood shingles can add a lot to the look of your house and, as a bonus, they are insect and rot-resistant, both features that will see less maintenance required and a longer lasting roof.

If a wood shingles roof is not correctly kept, it will lay witness to a greatly lessened lifetime. As wood is a naturally sourced material, each shingle is prone to both warping and cracking. If this happens and they are not quickly replaced with new ones, they will result in damage dealt to the roof.

Asphalt Shingles

Asphalt shingles are the most widely used wariant due to their easiness to install as well as them being a very cost-effective material. They commonly are addressed with a 25 year warranty, from this we can expect asphalt shingled roofs to last around 25 years. Despite this, asphalt shingle roofs can be seen having lifetimes of approximately 15-30  years.

The lifetime of each, individual roof will directly be impacted by the amount of maintenance that is performed in addition to the local weather. If the local weather is constant, harsh and damaging, the roof will consequently have a much shorter life.

If you have chosen architectural asphalt shingles to outfit your roof, they will live a bit longer than traditional asphalt shingles. They also typically are most expensive due to their 3 times thickness when compared to the traditional shingles. The warranty on these will also depend on the manufacturer but they typically last for 30 years.

Metal Roofs

The resilience of metal roofs is resulting in them becoming increasingly popular. The gauge or thickness of the material affects its lifespan. When generally, if the material is thicker, it will have a longer life.

Typically, thinner (26-29 gauge) metals will last approximately 20-25 years but higher-end roofs (22-24 gauge) will have lifespans of 50 years. The manufacterers’ warranty will differ as per each manufacturer but they usually can be anywhere from 20 years to lifetime.

Clay Tiles

Clay tiles are the most popular choice in certain places, but they are an expensive option. This investment is justified, however, clay tiles typically live for up to 50 years and it is common for manufacturers to put a 30 year warranty on them.

Additionally, clay tiles do not require the same amount of consistent maintenance as other materials due to their property of high resilience.However, it is still advised to have annual roof inspections to ensure any cracks are quickly noted. Furthermore, this should also be done following any storms as clay tiles are prone to cracking when hit by debris.

The expected lifespan of a roof is impacted both by the local weather and the shingles material. The most common asphalt shingles have expected life spans of 25 years. Where, the higher-end metal roofs can have lifetimes of 50 to 70 years when accompanied by the proper and required maintenance.
