Slate, copper and tile roofs, which are at the higher end of the price spectrum, can last more than 50 years. The average lifespan of a roof is usually between 25 and 50 years. However, the life expectancy of a roof ultimately depends on the quality, durability and type of material chosen. You usually get what you pay for, and the greater the investment in a new roof, the longer you'll protect your home, but there are a lot of options that homeowners and commercial property owners should consider when choosing the best type of roofing material.
A roof lasts 30 years on average. Slate roofs can last longer, up to 150 years. Asphalt shingles are the best replacement material for roofing. The lifespan of a roof is the number of years you spend outside it.
For a standard 3-tab asphalt shingle roof, it's 25 years. You can usually expect your roof to last about 20 years. However, the actual lifespan of your roof depends on several factors, including the type of roofing materials that were used and the environment. The key to having a durable roof is to schedule regular roof maintenance and inspections by roofing contractors.
While there are several factors that influence the lifespan of a roof, its lifespan depends largely on the materials used. A caliber of 22 to 24 is considered high-end among metal roofs and offers anticipated protection for 50 years or more, while higher-gauge metal roofs (25 to 2) offer standard protection for 20 to 25 years. However, because copper is so expensive, it is usually reserved for decorative roof parts and not for complete roofs. The climate where you live and the type of storms your roof faces influence the wear and tear you suffer.
When the asphalt shingles begin to be between 15 and 20 years old, or if the roof has been damaged by a storm, you should consider inspecting the roof to determine if you need to replace it. However, to replace an asphalt shingle roof due to hail, it is necessary to damage the soft metals (downspouts, gutters, ventilation ducts, or gaskets) found in the roof. Wind, hail, tornadoes, and other storms can cause even more damage by leaving gaps in the roof, removing protective granules from shingles, and accumulating moisture, causing mold and roof leaks. Two of the most common causes of premature roof breakdowns are improper roof installation and inadequate attic ventilation.
An accredited roofing contractor will recommend that you replace the roof between 80 and 85% of the roof's lifespan as established by the manufacturer. Often, the type of roof can have the biggest impact on the life expectancy of a roof, but this is just one step in the decision-making process. Usually, the expected life of the roof will be longer than the warranty offered for a roof, but the roof warranty is there in case the life of the roof is interrupted by a storm or major incident. With a thinner metal, the roof will last between 20 and 25 years, but choosing a thick, quality material will provide more than 50 years of protection.
Clay tile roofs won't last as long in colder climates, as constant freezing and thawing can easily damage shingles. In addition to being weather- and fire-resistant, clay tile roofs are easy to customize and offer homeowners versatility that other types of roofs simply don't.
