Algae, moss, and lichen don't just look bad — they actively degrade your shingles over time. Our bio-safe wash eliminates growth at the root, restores your roof's appearance, and protects against re-infestation for years.
Those black streaks across your roof aren't dirt — they're Gloeocapsa magma, a form of algae that feeds on the limestone filler in asphalt shingles. Left untreated, it gradually consumes the granule layer that protects your shingles from UV radiation.
Moss is even more destructive. Its root-like tendrils grow between shingles, physically lifting them and creating gaps where water can penetrate. A heavy moss colony can significantly shorten the remaining life of an otherwise sound roof.
Our bio-safe wash eliminates growth at the cellular level — without harsh bleach or high-pressure washing that strips the protective granule layer. We also apply a post-treatment sealant that slows re-infestation by 2–3 years.
Schedule Free AssessmentLow pressure, high effectiveness — the right way to clean a roof without causing damage.
We identify the type and extent of bio-growth and confirm the best treatment approach for your roof's material and condition. Not all algae and moss requires the same formula.
Our biodegradable formula is applied at low pressure to avoid shingle damage. It penetrates and kills growth at the cellular level — not just at the visible surface.
Once the treatment has adequate dwell time, we rinse the roof and remove loose debris. Results continue to improve over 30–60 days as remaining growth dies off naturally.
A protective treatment is applied to slow re-infestation. We recommend pairing with a GreenSoy™ Rejuvenation treatment for maximum roof life extension after cleaning.
High-pressure washing removes the granule layer that protects asphalt shingles from UV degradation. A single aggressive pressure wash can age your roof by 3–5 years. Our low-pressure bio-wash method is safer, more effective, and won't void your shingle warranty.
Let us assess the extent of bio-growth on your roof and recommend the right treatment — completely free, no strings attached.
