How Long Does a Roof Last? - A Comprehensive Guide

The average lifespan of a roof can range from 25 to 50 years, but the life expectancy of a roof ultimately depends on the quality, durability and type of material chosen. In general, roofs can last between 20 and 100 years, depending on the materials used, the quality of the workmanship and the climate. Asphalt shingles are the most common roofing material in the US and are expected to last between 15 and 25 years. Wind that enters from under any roofing material can quickly damage and reduce the life of the roof.

Metal roofs have a warranty that starts from 20 years, but it is determined by the type of material used. Clay shingles can weigh up to 950 pounds per square, so replacing an old asphalt roof with clay shingles may require reinforcing the house's roof structure. Metal roofs also have a lower carbon footprint than asphalt due to the significant quantities of petroleum products used in the manufacture of asphalt shingles. The average lifespan of a new roof depends on the type of roofing material you have and whether it was installed and maintained correctly or not. Other signs that it's time to replace a roof include damage caused by hail or falling branches, curved shingles, lack of shingles, and roof leaks.

The cheapest metal roof is made of corrugated panels, and one of them is expected to last between 25 and 40 years. Once the broken shingles reach about half of the total number of shingles, it's probably time to replace them completely. It's important to inspect your roof regularly and call an expert at the first sign of wear or roof leaks. This will help you identify any potential problems early on and take action before they become more serious. Regular maintenance is key to ensuring your roof lasts as long as possible.
