Why BC?
Why BC Roofs Need More Protection Than Most
The Lower Mainland and Fraser Valley have some of the most challenging roofing conditions in North America. Here's why GoNano treatment is especially valuable here.
Extreme Rainfall
BC cities receive 1,100–2,000+ mm of annual rainfall — 2–4× the Canadian average. This sustained moisture cycling depletes asphalt oils and accelerates granule loss faster than almost anywhere else in Canada.
Dense Tree Cover
Mature Douglas fir, cedar, and maple trees shade north-facing roof slopes, preventing them from drying between rain events. Shaded, damp surfaces are ideal for moss colonization.
Persistent Moss
Moss is the #1 cause of premature roof failure in BC. Once established, it holds moisture against shingles 24/7, lifts shingle edges, and creates pathways for water infiltration.
High Replacement Costs
BC labour rates and material costs make roof replacement among the most expensive in Canada — $15,000–$50,000+ depending on home size and location. The financial case for rejuvenation is especially strong here.
High Property Values
Lower Mainland homes are among the most valuable in Canada. A well-maintained roof protects that investment and supports resale value. GoNano treatment is one of the highest-ROI home maintenance investments available.
GoNano Is Built for BC
GoNano's NuRoof formula was developed specifically for high-rainfall, high-moss environments. The hydrophobic nano-coating prevents moss establishment and sheds water rapidly — exactly what BC roofs need.
