Moss, algae, and lichen removed safely with low-pressure soft washing and biodegradable solutions — protecting your shingles, preserving your warranty, and restoring curb appeal.
Every roof wash is a full soft-wash treatment — not just a rinse. We kill moss at the root and treat for regrowth prevention.
Low-pressure biodegradable solution is applied to the entire roof surface, penetrating moss, algae, and lichen colonies and killing them at the root — not just blasting them off the surface.
Our cleaning solutions are biodegradable and roof-safe, formulated specifically for asphalt shingles, cedar shakes, and tile roofing. Plants and landscaping are wetted and protected before application.
Before any solution is applied, we thoroughly wet all plants, shrubs, and garden beds adjacent to your home. We use diluted formulas and rinse everything down after treatment.
Optional zinc sulphate post-treatment creates an inhospitable surface for moss and algae regrowth — extending clean results by 1–2 additional years between service calls.
Asphalt shingles, cedar shakes, metal roofing, tile, and flat torch-on systems — we adjust solution concentrations and application methods to suit each material.
We photograph the roof before and after every service. You'll receive a full photo report documenting the transformation and any maintenance observations.
Moss roots penetrate shingle surfaces, lift edges, and allow water infiltration. Untreated moss can reduce an asphalt shingle roof's lifespan by 5–15 years.
Soft washing aligns with manufacturer guidelines. High-pressure washing explicitly voids warranties from GAF, CertainTeed, and Owens Corning — we never use pressure on roofing.
A clean roof dramatically improves the overall appearance of your home. Dark algae streaks and green moss patches are immediately removed, restoring the original roof colour.
Regular roof washing can add 10–15 years to the useful life of your existing roof — potentially saving tens of thousands of dollars in premature replacement costs.
We assess your roof size, pitch, and condition. Clear pricing with no surprises.

Plants protected, solution applied, full rinse completed. Moss killed at the root.
Before/after photos delivered. Optional regrowth prevention treatment applied.
Yes. We use low-pressure soft washing with biodegradable solutions formulated specifically for asphalt shingles. High-pressure washing is never used on roofs as it strips protective granules and can void manufacturer warranties. Our method is recommended by GAF and CertainTeed.
In the Fraser Valley's wet, moss-prone climate, every 2–3 years is typical. Heavily shaded roofs or those near mature trees may need annual treatment. Our post-wash zinc treatment can extend time between cleans by 1–2 years.
The treatment kills existing moss at the root. We also offer a zinc sulphate post-treatment that creates an inhospitable surface for regrowth for 1–2 years. For long-term prevention, zinc or copper ridge strips provide a continuous moss-inhibiting effect every time it rains.
Soft washing does not void shingle warranties. Most manufacturers specifically state that high-pressure washing voids the warranty and recommend low-pressure chemical treatment instead. Our approach aligns with GAF, CertainTeed, and Owens Corning guidelines.
We clean asphalt shingles, cedar shakes, metal roofing, tile roofs, and flat torch-on systems. Each material requires specific solution concentrations — we assess your roof type during the quote and adjust our approach to ensure safe, effective results.
Safe roof washing for Fraser Valley homes. Moss removed, warranty preserved, curb appeal restored. Response within 2 hours.
