Roof Leaks: Warning Signs

How to Spot Problem Areas

There are many tell-tale signs that your roof may need to be replaced or that you are in danger of experiencing roof leaks. A periodic inspection of your roof and attic will let you detect potential problems before they cause serious damage to your home.

1 Damaged Flashing

May occur due to improper installation, weathering or settling of the home’s foundation. Flashing problems are among the major causes of roof leaks.

2 Ceiling Spots

Caused by roof leaks. The source of the leak may be detected by an inspection in your attic.

3 Missing Shingle Granules

Bare spots on your shingles or an excessive amount of granules in your eavestroughs.

4 Blisters

Excess moisture in your shingles, caused by poor drainage or inadequate ventilation, can cause shingles to blister.

5 Shingle Buckling

Bucking of shingles may be caused by poorly installed underlayment, poor attic ventilation or when new shingles have been installed over old shingles.

6 Missing Shingles

Improper nailing or high winds can cause shingles to fall off.

7 Algae or Moss Growth

Large trees near your roof can provide an ideal growing climate for moss or algae.

8 Rotting

Excess moisture absorption and retention can cause shingles to rot.

9 Shingle Curling

Curling may be caused by improper nailing or lack of ventilation in your attic.
