Every roof is different. Cost depends on the size of your roof, the pitch, how much moss has built up, and accessibility. Submit a request or send us photos and we'll give you a clear, no-obligation quote.
Most Vancouver homes benefit from roof cleaning every 1 to 2 years. Properties with heavy tree coverage, north-facing roofs, or areas with limited sun exposure may need annual cleaning to prevent moss and algae from spreading and causing damage.
Not when it's done properly. We use a soft brush to remove moss by hand and never pressure wash roofs. Pressure washing strips the protective granules from asphalt shingles and can crack tiles. Our method removes moss safely without damaging your roofing material.
