It’s recommended to have your roof inspected at least once a year and after major storms to ensure there’s no damage or wear that could lead to bigger issues.

The lifespan depends on the material—most asphalt shingle roofs last 20-30 years, while metal, tile, or slate roofs can last 50 years or more with proper maintenance.

Signs like leaks, missing shingles, sagging, or visible damage may indicate the need for repairs or replacement. A professional inspection can help determine the best course of action.

The cost depends on factors like the size of the roof, the material chosen, labor costs, and whether old roofing needs to be removed.

In some cases, it’s possible to install a new layer of shingles over an existing roof, but it depends on the condition of the existing roof and local building codes.
