Protect your shingles and your curb appeal. Our shingle-safe roof cleaning removes algae, lichen, and debris without harsh pressure—preserving granules, extending roof life, and restoring a clean, even look.

We don’t pressure wash roofs. We use calibrated soft-wash chemistry to break down organic growth, then rinse carefully and finish with a preventative treatment to slow regrowth. Trained, insured technicians follow WorkSafeBC protocols and leave the site tidy.

what we clean
Every roof is different. We assess material, age, pitch, shade, and buildup, then tailor dwell times and gentle techniques to preserve granules and coatings while restoring a uniform finish.
what’s right for your property?
The safest approach is treatment-first: kill growth and spores, then allow weathering to release dead material. Limited gentle agitation is used where needed. We never high-pressure wash shingles, which can strip granules and void warranties.
