Why do my shingles have dark streaks?

Do you pull in your driveway, look up and see the roof of your home covered is dark streaks? That’s staining from airborne algae, a big problem here is the Sandusky, OH area.

Standard roof shingles are quite susceptible to the unsightly black staining, smears, blotches, and streaks caused by algae spores. Since the roof is such a large portion of a home’s exterior, and algae is difficult and expensive to clean, the discoloration can become an aesthetic nightmare which decreases the value of a home.

 If your roof is aged and stained with dark algae streaks it may be time to invest in replacing your roof with Streakfight algae-resistant shingles like Certainteed’s Landmark Pro.
