Builders LondonVarious Roof Systems to Choose From Determining which roof is right for you has many considerations; including style, color, durability, cost, and ease of installation. Asphalt roof shingles are the most common choice. They are available in many different colors, are relatively easy to install, and are relatively affordable in cost. They require little or no maintenance when new, but begin to crack and curl over time. Repairs are relatively easy to perform. The average life span of asphalt shingles is 15 to 20 years; high-quality shingles provides improved weather and fire resistance, and can last up to 35 years. Cedar shingles or cedar shakes are popular choices, but are significantly more expensive than asphalt shingles. Cedar shingles can last more than 20 years; properly installed and maintained, cedar shakes have a life span of 50 years or more. Left untreated, both have a poor fire rating; they will warp, split, rot, and weather. Therefore, periodic treatment with a product made for that purpose is recommended. Cedar shingles and shakes are neither difficult to repair or replace. A metal roof is becoming an increasingly popular choice. There are several types of metal roofing such as terne (tin/steel alloy), copper, aluminum, galvanized steel, and vinyl-clad steel. Some vinyl-clad steel manufacturers tout a life span of nearly 100 years; traditional painted aluminum or steel may last 35 years; terne lasting up to 50 years. Another modern upper end choice is a copper roof for both durability and appearance. A metal roof must be flashed and fastened with the same type metal to avoid electrolytic action and subsequent corrosion. Metal roofing is relatively expensive, but the life span of some choices can be well worth the investment Roof tile such as roof slate, concrete roof tile or clay roof tile has the longest life span of any roofing material; it will last for the life of the house, requires little maintenance, and is absolutely fire proof. However, an occasional cracked, broken, or chipped tile can be difficult to repair. If not attended to promptly and accurately, damage to existing roof system components beneath can result. Tile is heavy, has limited color choices, and is quite expensive. Built up roofing or hot roof is the most difficult to install. Hiring an experienced contractor is a must to completely waterproof flat or slightly pitched roofs. Built up roofing is fabricated on the roof itself, by laminating layers of special felt with heated asphalt, followed by a gravel topping. This is an expensive choice in roofing. Life span is relatively short; 5 to 20 years. The more layers, the longer the life expectancy. Rolled roofing is constructed from the same type material as asphalt shingles and is relatively inexpensive. It is simply rolled out in overlapping layers and fastened in place. It has a short life span of 5 to 15 years, and is used primarily as a quick fix. 1.
