The lifespan of a roof largely depends on the material used to construct it and the method of installation. Materials used in roof construction vary in terms of their longevity and resilience. These are typically some of the more popular roofing varieties. Here are a brief description of each, as well as the typical lifespan for each type of roof, and how long it would take to replace one if damaged.
Rolled Roofs have an average lifespan of about five years due to weather conditions which cause the seams to shrink. During extreme weather conditions, the metal flashing will become damaged, thus creating a hole or tear in the roof. Repairing this would require new tile construction, as well as a metal flashing strip, which will also need replacing after a significant amount of time. Although repairable, it is not a recommended solution for long-term use. Tile is slightly more difficult to replace, though when replaced with new tiling it is usually much easier to work with.
Asphalt Shingles is relatively inexpensive compared to other roofing varieties, especially when buying in large quantities. However, they are not fire resistant, and roofers often suggest replacing them more than once during extreme weather conditions. Also, asphalt shingles do not easily break down with fire and may not last very long when exposed to fire. It is important to replace these shingles once they become damaged, because they cannot be repaired once they have been damaged.
Tar/ Gravel Tar and gravel roofs have a longer lifespan than shingles because they are fire resistant and do not easily break down. Also, tar and gravel tiles are easy to install, which makes them a popular choice for new roof construction. Unfortunately, they are not as practical for long-term roofing because they are not as durable as asphalt shingles and not suitable for roof construction on slopes.
Granite Asphalt is the most durable and practical roofing material. It is highly flexible, so it can be installed quickly, which reduces the time it takes to install an asphalt shingle roof. The lifespan of this type of roof is usually between twenty and thirty years, depending on many factors including the location of the house, the quality of the material used, how the roof is constructed, and how it is maintained. It is also possible that it will increase in lifespan if it is maintained properly, such as with regular cleaning, sealing, and protection from the sun’s harmful rays.
Dimensional Shingles Unfortunately, dimensional shingles do not last anywhere near as long as asphalt shingles. They do however, provide a high level of durability that makes them a good choice for homes in high-traffic areas. However, they are not good choices for homes located in areas that experience any amount of direct sunlight. Direct sunlight can cause the wood fibers in the shingles to break down over time, so it is important to make sure your home has direct sunlight blocked off.
