How Algae Damages Your Roof
Roof algae is not just a cosmetic issue; it can seriously weaken your shingles over time if left untreated. Here’s how:
- Feeds on Shingle Fillers: Asphalt shingles contain limestone fillers that algae consume, gradually weakening the shingle’s structure.
- Granule Loss: As algae break down the surface, shingles lose their protective granules, leaving them brittle and prone to faster wear.
- Moisture Retention: Algae trap moisture in the shingle surface, accelerating aging, increasing the freeze-thaw cycle in winter, and leading to cracks.
- Heat Absorption: Dark streaks absorb more heat, raising roof temperatures and reducing energy efficiency.
- Shortened Roof Life: Together, these effects can take years off your roof’s expected lifespan.
Why Cleaning Matters
A clean roof doesn’t just look better, it performs better. Removing algae preserves your shingles, prevents premature replacement, and ensures your investment in rejuvenation or roofing lasts longer. Acting early helps you avoid costly repairs in the future.
Why We Use Sodium Hypochlorite and How It Works
We use a carefully measured sodium hypochlorite solution, the industry standard for safe, effective roof cleaning. Here’s why:
- Breaks down growth at the root: Eliminates algae, moss, and mildew at the cellular level.
- Fast-acting & gentle: Works within 10-20 minutes while remaining safe for shingles when applied professionally.
- Manufacturer-endorsed: Leading shingle makers recommend sodium hypochlorite soft washing as the approved method.
- Safe process: Applied with proper PPE, vegetation protection, thorough rinsing, and neutralization with sodium thiosulfate, it’s safe for your roof, landscaping, and the environment.
