Roof Cleaning in Chilliwack
Safe soft washing removes moss, algae, and lichen from your roof without damaging a single shingle. No high pressure. No voided warranties.
Why Roof Cleaning Matters in BC
Between October and April, roofs in the Fraser Valley sit under near-constant moisture — and that moisture feeds moss, algae, and lichen year-round. These aren't just cosmetic problems.
Moss
Anchors between shingles and lifts them as it grows, letting water work its way underneath — leading to rot, leaks, and premature failure.
Algae
The dark streaking you see on roof slopes. Feeds on limestone filler in asphalt shingles, breaking down the protective granule layer.
Lichen
The most aggressive of the three. Bonds chemically to roofing material and can permanently etch into shingles if left too long.
Our Process — Soft Washing, Not High Pressure
Inspection
We assess the roof type, slope, growth coverage, and condition before we begin.
Protection
Surrounding plants, gutters, and surfaces are rinsed and protected prior to treatment.
Soft Wash Application
Our biodegradable cleaning solution is applied at low pressure, penetrating organic growth and killing it at the source.
Rinse
A thorough low-pressure rinse removes residue and loosened debris without disturbing the roofing material.
Final Review
We walk through the result with you and answer any questions about ongoing maintenance.
Roof Types We Clean
Asphalt Shingles
The most common roofing material in the Fraser Valley. Soft washing is the only safe cleaning method — high pressure strips the protective granule layer and voids manufacturer warranties.
Cedar Shake & Shingle
Cedar is beautiful but highly susceptible to moss and lichen in BC's climate. Our soft wash treatment removes organic growth and helps preserve the wood's natural integrity.
Metal Roofs
Metal roofing holds up well in wet climates, but algae and lichen still form on its surface. We remove staining and biological growth without scratching the coating or finish.
