While damage to the roof can often go undetected, there are some obvious signs of a problem. If you notice any of the following issues, it's time to take action.

Rollover points for details.


1. Ceiling Spots

Ceiling spots are caused by leaks in your roof. To determine what's causing the leak, our Rooftop Genius crew check:
  • The roof for damaged shingles
  • The chimney and vents for cracks in the flashing
  • The attic and crawlspace for leaks
  • The rafters for leaks that have traveled from the original source

2. Algae Growth

Algae growth occurs when airborne algae is deposited on th roof. It's a common problem in warm, humid climates.

3. Curling

Curling is caused by inadequate ventilation, improper fely backing, or lack of back coating.

4. Buckling

Buckling is caused by improperly applied felt or movement in a deck.

5. Damaged Shingles

Damaged shingles are caused by exposure to high wind or improper fastening. They may be replaced individually, but it's not recommended.

6. Rotting

Rotting is a common problem with organic-based shingles and is caused when moisture is absorbed at the core of the shingle.

7. Damaged Flashing

Damaged flashing is the result of improper installation or drying and cracking. You might be able to replace it without replacing the roof.

8. Missing Granules

Missing granules on an aging shingle indicates the shingle needs to be replaced. On new shingles, a certain number of missing granules is normal.

9. Blistering

Blistering is caused by excessive use of ashpalt plastic cement or moisture in the shingles.
