Repairs can extend a roof’s life — but at some point, replacement is the smarter investment. Watch for these signs.

1. Curling or missing shingles

Shingles that curl, crack or blow off regularly mean the material is reaching the end of its life.

2. Granules in the gutters

Asphalt shingles shed granules as they age. Lots of grit in your gutters is a clear warning.

3. Sagging roof deck

A sagging line usually means moisture has damaged the structure underneath.

4. Daylight in the attic

If you can see light through the roof boards, water can get in too.

5. Age

Most shingle roofs over 20 years old are due for a professional assessment. Book a free inspection to find out where yours stands.
