As the most popular roofing material in the country, asphalt shingles offer unbeatable value. With proper care and maintenance, you can expect a well-installed shingle roof to last 15 to 20 years. If this time has approached or passed for your roof, make sure to contact a trusted roofer for an inspection. While an old roof may look perfectly fine, it could in reality rest on the edge of failure. A couple additional signs can also indicate the need for a new shingle roof.
Asphalt shingles are covered with fine gravel for two reasons. First, it contributes to the attractive appearance of shingle roofs. Secondly, it protects your shingles from impacts and drying out in the sunshine. Old roofs will naturally begin to shed granules. If you check your gutters and find large amounts roofing granules, then you need a new shingle roof. Faulty materials can also shed granules, so keep aware of what’s in your gutters.
Shingles can suffer damage from a variety of sources, most of them related to storms. Hail can leave your roof adorned with black circles from impacts, and can also bruise your roofing’s under-layers to leave softened spots. Wind can get beneath shingles to leave them creased, while excessively heavy rainfall can wash away roofing granules and increase the likelihood of leaks. Exceptionally heavy winds can actually devastate a roof’s shingles with airborne debris. Since damaged shingles cannot defend your home from leaks, they need replacement.
