How long different kinds of roofs last in different environments
All roofs have different life expectancies depending on what materials are used and what factors are at hand. For example, a central Arizona roof can last anywhere from 10-50 years depending on the roof systems installed on your home or building. Roofs made with tile can last up to 50 years, shingle roofs can live up to 30 years and foam roofs last around 15-25 years. There are many different types of materials with different longevity abilities. It’s important to do your research to see what best suits your commercial or multifamily project.
Shingle roofs can last for several decades. Asphalt shingles specifically (the most common type of shingled roof in most areas of the U.S.) can last around 15-25 with proper maintenance and inspections. The type of shingle will affect how long your roof lasts. For example, wooden shingles, cedar shingles or wooden or cedar shakes tend to last for much longer than asphalt shingles depending on your region, climate and other elements. However, asphalt shingles do better in Arizona, as wooden shingles are more susceptible to UV sun damage.
Metal roofs can last 50 years or longer with proper care and assuming no major weather events occur. These types of roofs have become increasingly common due to their longevity as well as their energy efficiency. They can often keep your property cooler in the summer and warmer in the winter. Standing seam roofing systems are the most common types of metal roofs you will see, as they are the most durable and weather-tight roof systems available in the industry. Their concealed fastener design allows them to last anywhere from 30 to more than 100 years.
Tile roofs can last for decades depending on what type of climate they are located in. They’re more popular in warm climates due to their efficient heating and cooling system. Clay tiles are most popular, especially for Arizona residents, but slate tiles are an option as well. These types of tile roofs have the ability to keep a roof well-insulated, regulating indoor temperatures and keeping expenses on AC and energy down. Their durability makes them highly water and storm resistant, able to withstand the intense monsoons and dust storms of the desert, protecting many Arizona homes from weather damage.
Spray polyurethane foam (SPF) roofs are wind and UV resistant. They have a life span of up to 50 years and require inspection every 10-20 years depending on how thick they are. A thicker coating will last longer than a thinner one, but with proper maintenance, SPF roofs can last for decades.
So how long do roofs last in general, and how long will your roof last? The life span of a roof depends on the materials used, quality of the installation, climate and major events or regional disruptions, and how often a roof is inspected and repaired. Regular inspections and performing proper maintenance are key to a long-lasting roof, and that’s why American Roofing & Waterproofing provides quality installation and materials to ensure your roof will last you for years to come.
