Algae Streak Treatment for Shingle Roofs in Bois D Arc, MO

Algae Streak Treatment for Shingle Roofs in Bois D Arc, MO

Those black or dark green streaks running down a shingle roof are usually Gloeocapsa magma, a blue-green algae that feeds on the limestone filler in asphalt shingles. It thrives in humid climates and on shaded, north-facing slopes. It does not cause leaks by itself, but it holds moisture and it makes a sound roof look old.

Bois D Arc, MO Shingle Roof Repair connects homeowners in Bois D Arc, MO with shingle roofing contractors who treat algae without damaging the shingles. That rules out pressure washing, which strips granules off the asphalt.

A typical treatment:

• Low-pressure application of a cleaning solution approved by the shingle manufacturer
• Rinsing at garden-hose pressure from the top down
• Protecting plants and gutters from runoff
• Installing zinc or copper strips just below the ridge, which release ions with each rain to slow regrowth

If you are planning repairs or a partial reroof anyway, ask about algae-resistant shingles, which have copper-coated granules mixed in.

Call (844) 238-0976 and Bois D Arc, MO Shingle Roof Repair will connect you with a crew in Bois D Arc, MO to clean up those streaks.
