What are those dark streaks on my roof?
If your asphalt shingle roof has dark vertical stains, you aren't looking at dirt or soot. You're seeing Gloeocapsa Magma—a blue-green algae species that feeds directly on the limestone filler used in modern asphalt shingles.
Left untreated, this organic growth causes real structural issues:
Eats away shingle granules: As algae feeds, shingles lose their UV-protective granule layer, leading to premature aging, drying out, and cracking.
Saves money on roof replacement: A dirty roof often looks like it needs to be replaced when it simply needs to be cleaned. Soft washing costs a fraction of a $15,000+ roof replacement.
Increases energy bills: Dark, stained roofs absorb excess heat from Colorado’s intense summer sun, driving up your home's air conditioning costs.
Prevents homeowners insurance cancellations: Insurance carriers increasingly issue policy cancellation notices for homes with visible roof moss or heavy algae buildup due to structural liability.
Why Front Range Businesses Trust LH Powerwash
Safe soft washing, never high pressure
Blasting a roof with a standard pressure washer strips away protective shingle granules, voids manufacturer warranties, and forces water beneath shingles into your attic.
At LH Powerwash, we strictly follow the Asphalt Roofing Manufacturers Association (ARMA) guidelines:
Low-Pressure Application: We use specialized equipment operating at under 100 PSI—gentler than a standard garden hose nozzle.
Eco-Friendly Cleansers: We apply proprietary, biodegradable cleaning solutions that sanitize the roof surface, breaking down algae, moss, and lichen spores at a chemical level.
Long-Lasting Sanitation: Because soft washing kills organic roots rather than just surface-blasting, your roof stays clean and streak-free 4x longer than high-pressure washing.
