Professional Cedar Roof Cleaning Across Ontario
Cedar shake roofs are built to last decades, but only if the wood stays clean and free of moisture-trapping growth. Brite Surface Cleaning provides specialized cedar roof cleaning as part of our broader roof cleaning services, using a soft wash process developed specifically for natural wood roofing. Our method removes moss, algae, lichen, and weathered buildup without splitting fibres or stripping the natural oils that protect cedar from decay.
Standard roof cleaning techniques are too aggressive for cedar. High pressure damages the wood and harsh chemicals break down the very properties that make cedar durable. Our team has cleaned cedar roofs on properties across Ontario, from lakeside cottages to heritage homes, and we know how to get results without compromising the material.

Trusted Cedar Roof Cleaning Specialists
Cedar shake roofs are designed to shed water quickly, but moss, algae, and lichen prevent that from happening. Organic growth traps moisture between and underneath the shakes, creating conditions for wood rot, shingle lift, and eventually water intrusion into your home. Once moisture is consistently held against the wood, the decay process accelerates rapidly. The natural oils in cedar give it resistance to rot and insects, but those oils deplete over time. Organic buildup speeds up that depletion by keeping the wood damp and blocking airflow. A cedar roof that is cleaned regularly maintains those protective properties far longer than one that is left to accumulate growth. A well-maintained cedar roof can last 30 to 40 years. One that is neglected may need full replacement in 15 to 20 years. The cost of routine soft washing is a fraction of what early replacement would run.
Our Professional Cedar 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 inspect your cedar roof thoroughly, checking for moss, algae, lichen, split shakes, curling, and any areas of soft or deteriorating wood. This assessment guides our cleaning plan and ensures we flag structural concerns before they are hidden by a fresh clean surface.
2. Apply Soft Wash Solution
Our eco-friendly, biodegradable formula is applied at very low pressure. It is designed to penetrate organic growth on natural wood without damaging the cedar fibres or stripping the protective oils. The solution needs time to work, so we let it dwell on the surface before rinsing.
3. Rinse With Low Pressure
A controlled, low-pressure rinse removes dead organic matter and cleaning solution residue. We work with the grain of the wood and follow the slope of the roof to prevent water from getting underneath shakes. No high pressure is used at any point during this step.
4. Final Check
We review the results with you from the ground and share our notes on the roof's overall condition. If we found any areas that need a roofer's attention, such as split shakes or soft spots, we provide that information along with photos.

Cedar Roof Cleaning - Frequently Asked Questions
Cedar requires much lower pressure and a gentler chemical approach than asphalt shingles or metal. The wood fibres can split, raise, or be permanently damaged by standard roof cleaning methods. We use a formulation designed specifically for natural wood and apply it at pressures low enough to clean thoroughly without causing surface damage. The technique, the products, and the timing are all different from what we would use on other roof types.
Every 2 to 3 years is a good baseline for most Ontario properties. Cedar roofs under heavy tree canopy or in particularly humid areas may benefit from annual cleaning. The goal is to remove organic growth before it roots deep enough to trap moisture and cause damage. If you can see moss or green patches from the ground, it is time to schedule a cleaning.
Cleaning removes organic growth and surface contaminants, which often makes a dramatic visual improvement. However, the natural greying of cedar is caused by UV exposure and oxidation, not dirt. A freshly cleaned cedar roof will look significantly better, but it will not return to the golden-brown colour it had when new. Some homeowners embrace the silver-grey patina as part of the character. Others choose to have the roof treated with a cedar-specific preservative after cleaning.
Yes. Our inspection before cleaning is thorough and honest. If we find split shakes, soft spots, areas of advanced rot, or structural concerns, we document them and share that information with you. We would rather you know about a problem early than discover it after water is coming through your ceiling. We are cleaners, not roofers, but we work alongside several experienced cedar roof specialists and can point you in the right direction.
Yes. We use biodegradable, eco-friendly cleaning solutions that are specifically formulated to be safe on natural wood. For lakefront properties, our solutions are lake-safe and will not harm aquatic ecosystems. The products break down organic growth effectively while preserving the natural oils in the cedar that protect it from decay.
