How Long Will Your Roof Last?

Maybe you’ve just had your roof replaced, or you’re doing some research because your existing roof requires a total makeover. Either way, you’ll want to know how long your new roof will last. Every roof will wear out over time, but how fast it happens will depend on the roofing material you choose.

How Long Does the Average Roof Last?

Asphalt Shingles

These are the most popular roofing materials in the U.S. because they’re relatively affordable and fairly durable. A typical asphalt shingle will last between 15 and 25 years. Thicker varieties like architectural or premium shingles are on the upper limit of the longevity range and can last anywhere between 20 and 40 years.

Metal Roof

Made from galvanized steel, zinc, or copper, metal roofs are surging in popularity because they’re very durable, fire-resistant, and environmentally-friendly. A metal roof has an expected lifespan of 40 to 70 years, depending on the grade and thickness of the metal.

What Can Affect the Lifespan of Your Roof?

Whether you have an asphalt shingle or metal roof, the longevity will depend on a variety of factors, including:


With proper installation of all roofing components and adherence to the manufacturer’s instructions, your roof is going to get as close to its lifespan as possible. Conversely, sloppy or improper installation will lead to early deterioration and premature replacements.


Taking care of your roof will ensure it stays in great shape and reaches the end of its expected lifespan. This means clearing off debris, trimming your trees, cleaning your gutters, looking for damaged roofing materials, watching for signs of water pooling, removing moss build-up, and making necessary repairs. Forgoing regular maintenance will shorten roof life.


Poor ventilation allows heat and moisture to build up in the attic. This can weaken shingles, put metal components at risk of developing rust, and cause decay in the roofing deck and support beams. A poorly ventilated attic reduces roof lifespan.

Weather Conditions

Nature is the number one enemy of roofing systems. While roofs are designed to provide a shield against outside elements, they wear down if repeatedly exposed to harsh conditions. Strong winds, heavy downpours, snow, ice, and hail will take a toll on even the strongest roof, reducing its lifespan. UV rays also accelerate shingle roof deterioration.
