Damaged shingles can be easily identified by a few tell-tale signs. These may include cracking, curling, or missing granules on the surface of the shingle. Additionally, if the roof is more than 20 years old, then it could be time to have it inspected for any issues that need attention. Roofing in Burr Ridge should be inspected at least once a year to ensure its integrity. If you notice anything out of the ordinary, then it is best to contact a professional at ASI Construction for an inspection and repair as soon as possible.
