Professional Roof Cleaning Across Ontario
Moss, algae, and black streaks do more than make your roof look neglected. They trap moisture, lift shingles, and shorten the life of your roofing materials. Brite Surface Cleaning uses a soft washing process to safely remove organic growth from shingle, metal, and tile roofs across Ontario without the damage that comes from high-pressure methods.
Our roof cleaning service covers every common roofing material in the province. For properties with cedar shake roofs, we offer a specialized cedar roof cleaning service with techniques developed specifically for natural wood. Whether your roof has a few dark streaks or heavy moss coverage, we tailor our approach to your material and condition.

Trusted Roof Cleaning Specialists
Many Ontario homeowners assume roof cleaning is cosmetic. It is not. Moss, algae, and lichen are actively damaging your roof every day they are present. They trap moisture against the surface, which accelerates decay, lifts shingles, promotes wood rot in the decking below, and can eventually lead to leaks inside your home. Ontario's freeze-thaw cycles make this worse. Moisture held against the roof by organic growth expands as it freezes, working into gaps and loosening materials faster than in milder climates. Even if your roof looks acceptable from the ground, hidden growth on the north-facing side or under tree canopy can already be weakening the surface. Routine soft washing removes these problems before they cause structural damage and helps extend your roof's lifespan by years.
Our Professional Roof Cleaning Process
We do not take a one-size-fits-all approach to deck cleaning. Wood decks require different treatment than composite, and a neglected deck covered in years of buildup needs more attention than one on a regular cleaning schedule. We combine soft washing and pressure washing techniques based on what your deck actually needs.
What Makes Our Approach Different?
- Cleaning method matched to your specific surface material
- Soft washing for delicate surfaces, pressure cleaning for heavy buildup
- Biodegradable, eco-friendly cleaning solutions
- Careful attention to all components and hard-to-reach areas
- Safe for surrounding landscaping and properties
1. Inspect and Assess
We evaluate your roof from the ground and, when safe, from the ladder line. We identify moss, algae, lichen, staining, and any signs of wear or damage. Then we build a cleaning plan based on your roof's material and condition.
2. Apply Soft Wash Solution
Our eco-friendly, biodegradable formula is applied at low pressure. It penetrates organic buildup and kills moss, algae, and mildew at the root without damaging the roofing material beneath. The solution is given time to dwell and do its work.
3. Rinse With Low Pressure
A controlled, low-pressure rinse washes away dead organic matter and cleaning solution residue. No high pressure is used at any point. Water is directed down the slope of the roof to prevent moisture from getting underneath shingles or panels.
4. Final Check
We walk through the results with you from the ground and review any areas we flagged during inspection. If we spotted anything that needs attention from a roofer, we let you know with photos and details.
Roof Cleaning - Frequently Asked Questions
Yes. Soft washing is specifically designed to clean roofs without causing damage. We use low pressure and a cleaning solution that does the work, so there is no risk of dislodging shingles, stripping granules, or forcing water underneath panels. We adjust our solution concentration and technique based on whether your roof is asphalt shingle, metal, tile, or slate. Cedar shake roofs require a different process entirely, which we offer as a separate specialized service.
For most Ontario properties, every 2 to 3 years is sufficient. Homes with heavy tree cover, north-facing roof sections, or properties in humid areas may benefit from annual cleaning. If you can see visible moss, dark streaks, or green patches from the ground, it is time to schedule a cleaning regardless of when the last one was done.
Soft washing will not void your warranty. In fact, most shingle manufacturers recommend against high-pressure washing and suggest soft washing as the approved cleaning method. Our process follows manufacturer guidelines for safe roof maintenance. We can provide documentation of our cleaning method if your warranty provider requests it.
Typical results last 2 to 3 years depending on your property's exposure to trees, shade, and humidity. Because our solution kills organic growth at the root rather than just removing it from the surface, regrowth is significantly slower than it would be after a simple rinse. Properties in open, sunny areas tend to stay clean longer than those under heavy canopy.
Roof cleaning is best done in spring through fall when temperatures are consistently above freezing. The cleaning solution needs time to work on the surface, and freezing temperatures interfere with that process. We recommend booking in the spring to remove winter buildup or in the fall before the season closes.
