The roofing material that lasts the longest is concrete, clay or slate shingles. These materials significantly outperform other natural products, such as wooden slats or any manufactured roofing material, including asphalt shingles and metal roofing. Although these materials have a good lifespan, they are not as durable. Composite asphalt shingles can be expected to last 15 to 40 years, depending on the quality of the materials chosen.
Some tile roofs can even last up to 50 years. Most tile roof manufacturers offer a range of products with different weights and different life expectancy. As a result, manufacturers such as Owens Corning, GAF or Certainteed come with high-end warranties that exceed half a century. Slate is a classic roofing material typical of the Northeastern United States.
It has been used for centuries in Europe, and many slate roofs in Europe are still in good condition hundreds of years after construction. While not cheap to install, a slate roof can last a lifetime and longer, easily exceeding 100 years. Installing a roof is a difficult and expensive housing project, so when it's time to replace the roof, you'll want your hard-earned money to go to a product that will last as long as possible. To keep it in good condition, the wood tile roof must be inspected annually and any broken shingles must be replaced immediately.
Maximizing the lifespan of a built roof is achieved by regular inspection and repair and by keeping debris away from the roof to prevent surface degradation. Simply put, slate roofs will last longer than most of the structures they adorn and are considered to be the best roofing material. A clay tile roof will last an average of 50 years, while metal roofs will last 20 to 70 years, depending on quality. It also helps you learn how to find a great roofing contractor, the different roofing components you'll pay for, how to pay for a new roof, and much more.
Except for maintenance and repairs, which can be significant, there should be no need to replace a well-constructed slate roof for 100 years or more. Solar panels installed on traditional roofs are common today, but solar shingles are still in their infancy. A metal roof with vertical seam can last 30 to 50 years and is resistant to many common types of roof damage. The thicker material also means that architectural tile roofs typically last much longer than three-tab roofs.
Another difference in asphalt roofing comes from the fact that there are actually two categories of asphalt roofing materials. Maintaining a tile roof by keeping it clean and free of debris and replacing it as needed will also extend its life. However, not all signs are visible to the untrained eye, so if you suspect damage, call a roofing professional to come out and inspect the roof. Those who live in particularly humid or humid climates and are considering replacing the asphalt roof may want to invest in specially manufactured, algae-resistant shingles.
Traditional shingles are made of terracotta clay, but there are also ceramic tile roofs (made of fired clay), as well as concrete tile roofs. Rolled roofs, which are used on relatively flat slopes, such as angled shed roofs, are installed by placing longitudinal strips along the roof in overlapping rows.
