In Metro Vancouver's wet climate, moss thrives on north-facing and shaded roof surfaces. It is not just unsightly — moss acts like a sponge, holding moisture against your roofing material 24 hours a day. That constant dampness drives water under shingles, rots the decking beneath, and can lead to leaks that cost thousands to repair.
Moss roots (rhizoids) physically lift and separate shingle edges, creating entry points for rain. On tile roofs, moss growth in the joints displaces mortar and compromises the weatherproofing. Left unchecked for two or three years, what started as a thin green film becomes a thick mat that requires aggressive removal.
Regular professional cleaning removes moss before it causes structural damage, extends your roof's lifespan by 5-10 years, and maintains your home's curb appeal and resale value.
High-pressure washing destroys roofs. It strips granules from asphalt shingles, cracks tiles, and forces water under flashing. We never use high pressure on roofing materials.
Our soft-wash process uses low pressure (equivalent to a garden hose) combined with a biodegradable cleaning solution that kills moss, algae, and lichen at the root. The solution breaks down organic growth over 20-30 minutes, then we rinse gently. The result is a clean roof with zero damage to the roofing material.
For heavy moss, we manually remove the bulk first with specialised tools that will not damage shingles, then soft wash to kill remaining growth and prevent rapid regrowth.
Tell us your roof type, approximate size, and how long since the last cleaning. Photos of the moss coverage help us quote accurately.
We provide a clear quote within one business day. Pricing is based on roof size, pitch, and severity of growth.
We need a dry day for proper treatment adhesion. Our crew arrives with all equipment — no access needed inside your home.
We document the results with photos and walk you through maintenance recommendations. Not satisfied? Call within 24 hours.
Complete moss removal and soft-wash treatment on a 14,000 sq ft natural stone roof. The property sits in a heavily treed area with significant shade, creating ideal conditions for rapid moss growth. Heavy manual removal followed by our biodegradable soft-wash treatment.
We clean 29,000 sq ft waterfront estate roofs and 1,200 sq ft townhome roofs with the same trained crew and the same careful approach.
"Cleanology did an amazing job on our roof and gutters. The moss was completely removed and our roof looks brand new. Very professional crew, on time and thorough."— Michael R., North Vancouver
"Our cedar shake roof was covered in moss after three years of neglect. They removed it all without damaging a single shake. The zinc strip treatment is keeping it clean months later."— Catherine P., Deep Cove
"We have used Cleanology for three years running. They handle our annual roof treatment and the moss never gets a chance to establish. Worth every dollar in roof longevity."— Sarah T., West Vancouver
Every 1-2 years for most homes. Properties with heavy tree cover, north-facing roofs, or in areas like Deep Cove and Lions Bay may need annual cleaning. Regular maintenance prevents the heavy buildup that requires more aggressive (and expensive) removal.
Yes. Our soft-wash process is safe for asphalt shingles, cedar shakes, concrete and clay tiles, metal roofing, and natural stone. We never use high pressure on any roofing material. The cleaning solution is biodegradable and will not corrode metal or degrade roofing adhesives.
Moss will eventually return in our climate — it is unavoidable with our rainfall. However, our treatment kills moss at the root and slows regrowth significantly. We also offer zinc or copper strip installation that provides ongoing prevention between cleanings.
Pricing depends on roof size, pitch (steeper roofs require more safety equipment), and severity of moss growth. A typical 2,000-3,000 sq ft residential roof runs $400-$800. We provide exact quotes after reviewing your property details.
Yes, we clean roofs year-round in Metro Vancouver. We need a dry day for treatment adhesion and avoid working in frost or ice conditions for safety. Winter is actually a good time — moss is actively growing and the treatment is highly effective.
No. We work entirely from the exterior and do not need access inside your home. We just need clear access around the perimeter and any gates unlocked. We will send before and after photos when the job is complete.
