Protect Your Roof. Extend Its Life. Restore Its Appearance.

Those dark streaks and black stains on your roof aren't just cosmetic problems—they're living organisms eating away at your shingles. Gloeocapsa magma (the algae that causes those ugly black streaks), moss, lichen, and mold don't just make your roof look old. They actively deteriorate roofing materials, shortening your roof's lifespan and leading to costly repairs or premature replacement.

G.I. Bins uses a soft wash roof cleaning system that safely eliminates algae, moss, and organic growth without the damaging high pressure that can strip granules from shingles or void your warranty. Our low-pressure application combined with specialized, eco-friendly cleaning solutions kills growth at the root and keeps your roof cleaner longer.

Why roof cleaning matters: A dirty roof does more than hurt your curb appeal. Algae and moss retain moisture against your shingles, accelerating wear and creating conditions for rot and leaks. Dark stains absorb more heat, increasing your cooling costs in summer. And if you're thinking about selling, a stained roof signals "deferred maintenance" to buyers and appraisers—potentially costing you thousands at closing.

Our soft wash process: We apply a biodegradable cleaning solution at low pressure that kills algae, mold, and moss on contact. No damaging high-pressure blasting. No risk to your shingles, flashing, or gutters. The solution continues working after we leave, and rain naturally rinses away the dead organic matter over the following weeks—revealing a clean roof that looks years younger.

Safe for all roof types: Asphalt shingles, tile, metal, cedar shake, and flat roofs. We adjust our approach to match your roofing material.
