Cedarwood Cleaning uses gentle, manufacturer-approved methods that protect your roof while eliminating moss, algae, debris, and harmful buildup. Our soft washing treatments are designed specifically for West Coast homes, where damp weather causes moss to spread quickly. Whether you're preparing for winter, extending the life of an aging roof, or dealing with heavy moss growth, our roof cleaning service helps protect your home and prevent costly damage.
Why Roof Cleaning & Moss Removal Matter
On Vancouver Island, roofs grow moss faster than almost anywhere else in Canada. Our damp coastal climate creates the perfect environment for moss, algae, and lichen to take hold and slowly destroy roofing materials.
Unchecked moss can cause:
-
Lifted or curled shingles
-
Cracked or broken shingle edges
-
Premature roof aging
-
Water intrusion and leaks
-
Rot in the roof deck & underlayment
-
Reduced lifespan of asphalt shingles
-
Higher risk of mold inside the home
What We Remove During Roof Cleaning Procedure
-
Our roof cleaning service safely removes:
-
Moss, lichen & algae
-
Black streaks and organic staining
-
Debris, leaves & pine needles
-
Clogged roof valleys
-
Branches & tree buildup
-
Gutter-edge moss growth
-
Loose surface debris
-
Roofline buildup
-
Every roof is cleaned using low-pressure, manufacturer-safe soft washing, never damaging high pressure.
Moss might look harmless, but the roots dig in and hold moisture against your roof — leading to expensive repairs.
Regular roof cleaning saves thousands by extending the life of your roof.
Our Safe Roof Cleaning Process
Request a Free Quote
We inspect your roof type, pitch, moss level, and access requirements.
Manual Debris Removal
Large moss clumps, branches, and roofline debris are carefully removed by hand with a soft bristle brush. We are very careful not to damage or compromise your roofing material.
Soft Wash Treatment (No Pressure)
We apply an eco-friendly, manufacturer-approved moss treatment that kills moss and algae at the root without harming shingles.
Gentle Rinse (if required)
Depending on the roof type, we may rinse low-pressure or allow the treatment to weather off naturally (preferred method for roofing longevity).
Quality Check & Walkthrough
​After the cleaning is complete, we perform a detailed quality inspection to ensure every part of your roof has been properly treated and cleared. We then walk you through the results, answer any questions, and provide guidance on maintaining a clean, healthy roof.

Roof Cleaning & Moss Removal FAQ
Q: Is pressure washing safe for roofs?
No. High-pressure cleaning can tear off shingles, strip granules, and void your roof warranty. That’s why we only use soft washing and manual removal.
Q: Will moss grow back after treatment?
All moss will die after our treatment, but regrowth depends on shade and moisture. Most roofs stay clear for 12–24 months.
Q: Do you walk on the roof?
Only when safe and necessary. When possible, we work from ladders or rooflines to protect the shingles.
Q: What's the safest way to remove moss from my roof?
Soft washing + gentle manual removal. Hard brushing or pressure washing causes damage.
Q: Do I need to be home during the cleaning?
Not necessarily — as long as we have exterior access. We’ll confirm all details during your quote.
Q: Will cleaning extend the life of my roof?
Yes. Removing moss prevents shingle separation, leaks, and moisture buildup that cause early roof failure.
Q: Are the cleaning products safe for plants and pets?
Yes — we use biodegradable, eco-friendly solutions and pre-rinse landscaping around your home.
