How long a roof lasts will depend on the type of shingle, the brand of shingle, the quality of the shingle, and the components of the roof. But it also depends on the skill of the roofers who install the structure.

On average, a roof will last for between twenty and twenty-five years. It’s rare to see one last much longer than that, but it does happen. However, poor workmanship during the installation can potentially reduce its life expectancy or cause premature failure of the roof system.

Roofing contractors provide workmanship or manufacturers’ materials warranties or a combination of both. Most roofing contractors provide a ten-to-fifteen-year workmanship warranty on asphalt shingle roofs. Asphalt shingle manufacturers provide a lifetime warranty, provided it’s been registered with the manufacturer within a designated time after the roofing job is completed. In the event there is a defect with the product, most manufacturers require installing a minimum of three or more accessories from the product line to qualify for their warranty. Failure to follow the manufacturer’s installation specifications may void the warranty. On average, a roof will last for between twenty and twenty-five years. It’s rare to see one last much longer than that, but it does happen. However, poor workmanship during the installation could, in fact, reduce its life expectancy or cause premature failure of the roof system.
