The answer to 'shingles damage' is that common causes of shingle damage include severe weather, improper installation, aging, and lack of maintenance. Symptoms can include curling, cracking, missing granules, and leaks. The best solution depends on the extent of the damage, but often involves replacing damaged shingles or the entire roof.
For minor issues like a few missing or cracked shingles, homeowners may be able to make simple repairs themselves. However, for widespread damage or leaks, it's generally best to call a professional roofing contractor to inspect the roof and provide the appropriate repair or replacement solution.
