Due to the hot humid weather here in New England, a lot of roofs grow algae on them. Sometimes it’s easier to notice then others. Sometimes it’s not. How do you know if you have algae on your roof ? How do you remove it?

The algae growth on roofs are microorganisms which grow in moist conditions. They spread by releasing spores into the air. Those spores typically require a moist surface to open. If the moist surface they land on is your roof, that’s where they bloom.

Do You Have Algae on Your Roof?

Black streaks on your shingles is the most common sign you have algae on your roof. The most common sign you have algae growth is black streaks on your shingles. You may think those are just dirt streaks on your roof but they’re not . The algae streaks can come down the side of the house and stick to the siding and trim.

You may not see the streaks near metal flashing because the zinc coating on galvanized steel repels algae. Copper flashing also repels these growths. Metal particles can flow down the roof with rainwater, killing off any algae growth in its path. Blue-green algae, the most common form that grows on roofs, is usually not harmful to the roofing materials. The biggest problem is the streaks the algae cause.

How Do You Deal with the Algae?

Chlorine bleach will kill the mold on homes or businesses with shingle roofs. A solution of bleach and water gets sprayed on the roof’s surface and left there for a short time. After that, it’s crucial to spray the entire surface down with clean water to prevent the bleach from lingering. If left untreated, it could damage roofing nails and other materials.

It’s probably best to have a local cleaning company like TMG Cleaning Services perform the work. They know the proper solution to use and have the equipment to do the job properly. We definitely don’t want to see you up on a ladder.

How Do You Prevent Algae Growth?

To prevent algae from growing or coming back, you need to get as much sun to your roof as possible. Cut back your trees which shade the roof. Keep debris from accumulating. Clean your gutters so moisture has a place to go.
