Aspha lt Shingles Your home’s roof should give you many years of service. Asphalt shingles are the most common type of roofing material but alternatives such as tile, concrete, wood, rubber and metal are becoming more popular. Following heavy windstorms, homeowners are encouraged to check for loose, broken or missing shingles. Builders are not responsible for repairing storm-related damage. A damaged roof should be repaired as soon as possible to prevent leakage into the interior of your home. Roofs can also be damaged when items such as a satellite dish are installed. Use care during these installations to avoid damaging the shingles and ensure hold-down devices (e.g. screws) are properly sealed to prevent leaks. Asphalt shingles are soft on warm days and can easily be damaged if you walk on them. If you must be on the roof, it’s best to do so early in the morning when the shingles are still cool to the touch. Slight differences in colour are inherent to the manufacturing process of asphalt shingles, even within the same factory run. This is unavoidable and does not affect durability. As shingles age, they will shrink and curl slightly. New shingles may curl or cup if exposed to cool temperatures. The surface of a shingle cools when frost forms. At the same time, the underside of the shingle receives passive heat from the attic. This temperature difference can cause the shingle to lift or curl slightly. Shingle age and type, attic ventilation, roof pitch, humidity, climate, colour, etc. will determine the visibility of any lifting or curling. This movement will not affect the performance of the shingles. Why are my asphalt shingle edges curled/cupped? 74 ANHWP.COM • ALBERTA NEW HOME WARRANTY PROGRAM
