Roof Cleaning & Moss Removal in
Surrey, BC & Metro Vancouver
Eradicate stubborn moss roots, black algae streaks, and lichens without destroying your shingles. Our gentle soft-wash chemistry preserves your roof, restores curb appeal, and is backed by a 2-Year No-Moss Warranty.
Gentle Soft Washing vs. Destructive Power Washing
Standard high-pressure power washing strips protective shingle granules, creating leaks and voiding roof warranties. Our soft-wash technology treats the root cause safely.
Low-Pressure Soft Washing (<100 PSI)
After brushing, we apply a soft wash moss treatment using an ARMA-guideline tested solution (Asphalt Roofing Manufacturers Association).
Interior Gutter Cleaning Included
Every standard roof cleaning includes interior gutter cleaning, so the moss and debris we remove don't stay in your gutters.
2-Year No-Moss Warranty
Every full roof cleaning includes our 2-Year No-Moss Warranty. If moss returns within 24 months, our crew comes back to treat it at no extra cost (see warranty terms).
Helps Extend Your Roof's Life
Moss acts like a sponge, trapping coastal humidity and freezing in winter to lift shingles. Roof cleaning helps prevent premature $15,000+ roof replacements.
WorkSafeBC Covered & Fall-Protection Certified
Our technicians are fall-protection certified, using non-marking boots, harness anchors, and $2,000,000 commercial liability coverage on every steep roof.

Surrey Roof Cleaning, Moss Removal & Pricing Guide
Everything homeowners in Surrey, White Rock, Langley, and Metro Vancouver need to know about coastal roof moss growth, soft-washing chemistry, shingle granule protection, and fair pricing.
What's Included in Every Professional Roof Wash
When you hire Two Brothers Roof Clean Ltd. for your home, you receive a full-service, end-to-end roof restoration tailored specifically for British Columbia's damp coastal climate:
- •Comprehensive Roof Inspection: We check shingle integrity, roof pitch angles, skylight seals, chimney flashing, and valley drainage.
- •Low-Pressure Soft Wash Biocide Treatment: Safe, follows ARMA roof-cleaning guidelines chemical application that kills 100% of moss, lichens, and black gloeocapsa magma algae.
- •Manual Heavy Moss Clump Gentle Brushing: Soft-bristle removal of large moss cushions without tearing or lifting shingle tabs.
- •Complete Gutter & Downspout Flush: Clearing all fallen roof debris and moss clumps so rain flows freely.
- •Perimeter Deck & Garden Cleanup: Rinsing off all exterior ground surfaces, windows, and siding touched during the roof wash.
Why High-Pressure Pressure Washing Destroys Shingles
Many inexperienced contractors try to blast roof moss off using high-pressure pressure washers (2,500+ PSI). This causes catastrophic, permanent shingle damage:
- •Loss of Protective Mineral Granules: High pressure strips the protective asphalt coating that defends against sun UV breakdown and roof leaks.
- •Voided Roof Warranties: Major manufacturers like GAF, Owens Corning, and CertainTeed explicitly void warranties if pressure washers are used.
- •Water Driven Under Shingle Flaps: High pressure forces water backward underneath shingles, rotting plywood decking and causing interior ceiling leaks.
How Roof Cleaning Pricing Is Calculated
We provide transparent, upfront pricing with zero hidden fees. Your customized quote is calculated based on four straightforward property factors:
- •Total Roof Surface Area (Square Feet): Overall size of your roofline (ranchers vs. 2-story or 3-story executive homes).
- •Roof Pitch & Slope Steepness: Walkable low-pitch roofs vs. steep gables requiring specialized safety harness tie-offs and anchor rigging.
- •Moss & Algae Severity: Light black algae streaks vs. heavy, thick green moss cushions requiring extra biocide application.
- •Roofing Material Type: Architectural asphalt shingles, cedar shake, concrete tile, or standing seam metal.
2-Year Guarantee & Preventative Maintenance
Our process (manual brushing, then a soft wash moss treatment) removes the bulk of heavy moss on the spot. Remaining growth dries out and detaches naturally with rain within 2–3 months.
Every full roof clean is backed by our 2-Year No-Moss Warranty. We also offer optional biannual moss preventative sprays to keep your roof looking brand new indefinitely for a fraction of full cleaning costs.
