How Long Will My New Asphalt Shingles Last on My Roof?

Posted on July 5, 2018 · Posted in Asphalt Shingle Roofing

There is a reason why asphalt shingles have been trusted to cover rooftops for decades. Simply put: they get the job done. Particularly in Maine and the Northeast, asphalt shingles offer a flexible, durable, and affordable option for nearly any roof shape or size. While metal and rubber roofing options may be a better fit for some applications, it’s hard to go wrong with asphalt shingles.

There are a number of variables that can affect the lifespan of asphalt shingles, including weather, maintenance, and location. For those living in southern states, heat and humidity can shorten the lifespan of asphalt shingles. While in northern states, cold temperatures and harsh winters can do the same.

Those living in milder climates can generally expect asphalt shingles to last for over 20 years. In hotter and colder climates, the life expectancy of asphalt shingles decreases. In Maine, the average life expectancy of asphalt shingles is 20 years, with a lifetime warranty that is prorated for some products after the first 10-15 years. If anything fails on the shingle application in the first 10-15 years it’s covered, after that the warranty is prorated.

Additional items that can impact the life expectancy of your asphalt shingles are your local location —- are you on the water? Are you on a hill that receives more wind? Are you under heavy tree coverage where leaves and branches may land and promote the pooling of water or even rot on your roof?

Regular maintenance and inspections of your roof can significantly help in increasing your roofing materials’ lifespan. Contact your local roofing company to schedule routine inspections before and after winter, or extreme storms.
