Here are some signs that might indicate you need a new roof:
1. Leaks or Water Damage: If you notice water stains on your ceiling or walls, it could be a sign that your roof is leaking or has damaged shingles.
2. Missing or Damaged Shingles: If shingles are cracked, curling, or missing, your roof is more vulnerable to leaks and damage.
3. Sagging Roof: A sagging roof could indicate structural issues or water damage to the roof’s decking, which could require a replacement.
4. Granules in the Gutters: Asphalt shingles lose granules over time. If you find a significant amount of granules in your gutters, it could be a sign your shingles are deteriorating.
5. Daylight Showing Through the Roof Boards: If you can see daylight through your roof boards in your attic, it indicates that there is significant damage to the roofing material.
6. Age of the Roof: Roofs typically last 20-25 years. If your roof is near or beyond that age, it may be time for a replacement.
7. Moss or Algae Growth: While not always a sign of immediate failure, excessive moss or algae growth can trap moisture, leading to roof damage over time.
8. Persistent High Energy Bills: A poorly insulated or damaged roof can allow heat or cool air to escape, increasing your energy bills.
9. Visible Wear and Tear: If your roof looks worn out, with cracks, buckling, or spots that appear damaged, it could be time for a new roof.

If you’re noticing several of these signs, it’s a good idea to have a roofing professional inspect the roof to determine if a replacement is necessary.
