Cedar Roof Cleaning in Hamilton

The fine airborne particles settle on the shakes and embed in the wood grain over time. This creates a surface that holds moisture longer than clean cedar would, which accelerates moss and algae growth. The particulate also dulls the natural colour of the cedar, turning it a uniform dark grey that looks like weathering but is actually surface contamination. Our cleaning solution breaks down the particulate bond and removes it along with the organic growth.

Every 2 to 3 years is a good baseline. Properties in Ancaster or Dundas with heavy tree cover and limited sun exposure may benefit from annual cleaning. The goal is to remove organic growth before it roots deep enough to trap moisture and start decomposing the shakes. If you can see moss, green patches, or heavy debris accumulation from the ground, it is time to schedule a cleaning.

Yes. We do a thorough visual inspection of every cedar roof before we begin. If we find split shakes, soft spots, significant curling, or areas of advanced rot, we document them and share the information with you along with photos. We are cleaners, not roofers, but we work with experienced roofing contractors in the Hamilton area and can point you in the right direction for repair work before or after the cleaning.
