Asphalt shingles are great, resilient and durable materials, but like any roofing system, asphalt roofs can get damaged by many things or they can simply reach the age when they can no longer stay on the house. Here are some signs to indicate that your asphalt shingle roof needs to be replaced:
- Curled and cupped shingles – whether caused by hail or exposure to water and UV radiation, cupping and curling are signs of severe damage. If the problem affects over 30% of your roof, it is a good idea to consider roof replacement; Expert Aurora roof repair contractors can look inspect your roof and recommend repairs and/or replacement as needed.
- Missing granules – asphalt shingles consist of multiple layers, the topmost layer consisting of mineral granules to ensure resistance to the elements. The impact sustained by the roof during storms can easily dislodge those granules, leaving the shingle mat exposed and compromising the material’s weather protection abilities. If you see that the granules are missing from most of your shingles, the best solution might be to get a new roof;
- Roof sagging – if your roof slope or the ridge are no longer straight, it is a sign that your roof’s support structure has been compromised and that you should take action to repair or to replace the roof as soon as possible.
