What Roof Washing Helps Protect
Moss does more than make a roof look neglected. Dense growth can hold moisture against the surface, collect debris, interfere with drainage, and contribute to premature wear. As moss thickens, it may also work beneath shingle edges and make future cleaning more involved.
Routine roof care removes or treats growth before it becomes more established. It also makes it easier to see the condition of shingles, flashing, valleys, vents, and other roof details that may need maintenance.
For Aldergrove homes surrounded by trees or exposed to long periods of shade, preventative cleaning can be an important part of protecting the roof’s service life.
Our Four-Step Approach to a Healthier Roof
Why Top Dawg Is a Safer Choice for Roof Care
Technicians Trained for Roof Work
Roof cleaning requires more than general exterior cleaning experience. Our technicians follow established safety procedures from the Canadian Centre for Occupational Health and Safety and use approved methods from the Asphalt Roofing Manufacturers Association suited to roof materials, slopes, access conditions, and the type of organic growth present.
Soft Washing Instead of High Pressure
High-pressure washing can loosen shingle granules, damage edges, and drive water beneath roofing materials. Our roof cleaning process relies on controlled application and roof-safe pressure, allowing the treatment to do the cleaning work.
Preventative Maintenance, Not Just Curb Appeal
Careful Work Around the Entire Property
Roof treatment affects more than the surface above. We plan for runoff, nearby gutters, plants, siding, patios, and other surrounding areas, taking appropriate precautions before, during, and after application.
PROTECT YOUR ALDERGROVE ROOF BEFORE MOSS TAKES OVER
Whether your home is near Aldergrove’s town centre, Bertrand Creek, Jackman Road, or a wooded rural property toward Otter, Top Dawg can recommend a roof washing plan based on the specific material and amount of growth.

Frequently Asked Questions About Roof Washing in Aldergrove
Soft washing is the safest and most effective approach for most roofs, according to guidance from the Asphalt Roofing Manufacturers Association. It uses a specialized cleaning treatment and low-pressure application to break down moss, algae, lichen, and staining without blasting the surface. Pressure washing should not be used on shingles because it can remove protective granules, damage edges, and force water beneath the roofing.
Many Lower Mainland roofs benefit from professional cleaning every two to three years, but the right schedule depends on tree cover, shade, roof pitch, material, drainage, and how quickly growth returns. Aldergrove roofs beneath mature trees or with shaded north-facing sections may need attention sooner. Visible moss, dark streaks, blocked valleys, or persistent debris are signs that it is time for an assessment.
Professional soft washing commonly uses a carefully diluted sodium hypochlorite solution with water and specialized surfactants. The active solution targets moss, algae, and lichen, while the surfactants help it remain on the surface long enough to work. Trained technicians adjust the concentration, application, and property-protection steps for the roof and surrounding landscaping.
Late spring through summer often provides the best combination of drier weather, mild temperatures, and safer roof conditions in the Fraser Valley. Treatment still depends on the forecast, roof moisture, temperature, and safe access. If moss is already established, it is better to request an assessment than to wait through another full wet season.
In most cases, you do not need to be home as long as our technicians have clear access to the exterior and any required water connections. We can confirm the details with you when the service is scheduled.
