There are a few things to watch for when assessing whether repairs need to be made:
- Broken and Cracked Shingles - Too many broken and cracked shingles will compromise your roof’s integrity. These should be repaired to ensure proper protection.
- Wide Gaps - When roofing materials age, they will shrink. This can lessen the protective covering of the roof and allow moisture to seep into the attic. Gaps should be about 3/8” wide. When they become ¾” or more, it is time for repairs.
- Shingle Curling - Curling at the edges of the shingles is a common sign that they are aging. This can sometimes be observed from the ground and is an indication that your roof needs attention.
- Mildew and Algae - Shady roofs can have fungus and algae grow on them. This type of growth can be limited by trimming trees to allow sunlight to reach the surface.
- Age of the Roof - Asphalt shingles, the most common roofing material, will last about 20 years. If your roof is approaching its suggested lifetime, consider having a professional take a look.
