The answer to 'asphalt shingles worn out' is that asphalt shingles typically last 15-30 years, but can wear out prematurely due to factors like weather, poor installation, or lack of maintenance. Symptoms of worn-out asphalt shingles include curling, cracking, bald spots, and granule loss. Solutions may involve repairing or replacing the damaged shingles, or in severe cases, re-roofing the entire house.
For minor shingle issues, homeowners can often make DIY repairs. However, extensive damage or a full roof replacement is best handled by a professional roofing contractor. They have the expertise and equipment to safely and properly address the problem.
