Why do some roofs have light spots or streaks?
In our warm, humid Gulf Coast climate, algae can grow on asphalt shingles, leaving dark or light streaks that make your roof look older than it really is. While algae usually doesn’t mean your roof is failing, it can definitely hurt your home’s curb appeal.
The good news? Most modern architectural shingles are manufactured with algae-resistant technology. These shingles contain copper-infused granules that help prevent algae growth, keeping your roof looking cleaner for years to come.
If your roof is due for replacement, ask about algae-resistant shingles. It’s a small upgrade that can make a big difference in the appearance of your home.
