While some signs are more obscure, others are easier to spot. Here are a few warning signs that it’s time to replace your shingles:
Curled, cracked, wet, dirty, or missing shingles are the most visible signs of damage. Rotting shingles are “contagious”, so if you see one or two problem spots, the issue has more than likely spread to other shingles. Expect to repair or replace several shingles.
- Shingle granules built up in your gutter:
Composite or asphalt shingle granules look like wet, coarse sand when they begin to shed. To make matters worse, they may wind up in your gutter, causing a host of other issues if not taken care of quickly.
- Peeling or blistering exterior paint:
If your attic is not ventilated correctly, water or increased humidity builds up near the roofline. As a result, your paint becomes discolored and starts to chip away.
Lichen is a fungal growth with high levels of acidity. Without consistent upkeep, lichen could go unnoticed, causing shingles to rot from the acidity.
