Vancouver gets over 160 rainy days a year — close to ideal moss-growing weather. Asphalt shingles rated for 25–30 years in drier climates often only make it 15–20 here. GoNano nanotechnology extends your shingle life by 10–15 years at a fraction of replacement cost. Free assessment, no obligation.
Vancouver gets over 160 rainy days a year and roughly 1,150–1,200mm of annual rainfall — close to 50% more than a city like Toronto. Combined with mild year-round temperatures that rarely bring a hard freeze, this is close to ideal moss-growing weather. The result: asphalt shingles rated for 25–30 years in drier climates often only make it 15–20 here.
A huge share of East Vancouver homes are Vancouver Specials or pre-war Craftsman houses built with low-slope or built-up roofing that shows wear differently than steep-pitch asphalt — making the 8–18 year treatment window especially relevant for this housing stock.
Many Vancouver homeowners are told they need a full replacement when their roof actually qualifies for rejuvenation. If your shingles are 8–18 years old with no structural deck damage, GoNano treatment is almost always the smarter option — especially given how much Vancouver's climate accelerates wear versus a shingle's rated lifespan.
GoNano NuRoof™ penetrates the shingle at the molecular level, replenishing the oils that keep asphalt flexible and waterproof — it's not a surface coating, it's a genuine restoration of the shingle material. The hydrophobic nano-coating also helps prevent moss from re-establishing, which matters in a climate where nearly every untreated roof develops visible moss within a few years.
One visit, 2–4 hours. No tear-off, no dumpster, no multi-day crew. Typical cost for a Vancouver home is $1,800–$3,800 — versus $15,000–$30,000 for full replacement.
Vancouver homeowners searching for roof rejuvenation near East Van, Kitsilano, Mount Pleasant, Dunbar, or Kerrisdale will find GoNano treatment to be the most affordable path to extending shingle life — typically $1,800–$3,800 versus $15,000–$30,000 for full replacement. NanoShieldBC is Vancouver's certified GoNano applicator, serving all City of Vancouver neighbourhoods including Vancouver Specials, pre-war Craftsman homes, and strata buildings. Financing available from approximately $150/month through iFinance Canada.
For most Vancouver homeowners with roofs aged 8–18 years, asphalt shingle restoration through GoNano treatment is the smarter financial choice — delivering the same extended lifespan at a fraction of the cost.
GoNano asphalt shingle restoration comes in two formulas — one preventive, one restorative. We assess every roof individually to recommend the right one for your home.
Preventive GoNano roof treatment for roofs still in good condition. Creates a powerful hydrophobic nano-coating that dramatically slows aging, prevents moss damage to shingles, and extends shingle life before significant deterioration begins.
Restorative asphalt shingle restoration for aging roofs showing granule loss, early curling, or oxidation. Penetrates the asphalt matrix to restore lost oils and flexibility — the smart alternative to roof replacement.
We provide free roof assessments and GoNano treatment throughout Vancouver and surrounding communities.

"We were quoted $23,000 for a new roof on our East Van home. NanoShieldBC came out, assessed it, and said it qualified for treatment. $2,900 later and the roof looks brand new — and we have a 10-year warranty."
It's largely the climate: frequent rain, mild temperatures with no hard winter freeze, and tree shade in many neighbourhoods create close to ideal conditions for moss and moisture damage. A shingle rated for 25–30 years elsewhere often shows significant wear in Vancouver by year 15–18.
Yes, for asphalt shingle roofs meeting the age and condition criteria. Many East Vancouver homes — Vancouver Specials, pre-war Craftsman houses, and post-war bungalows — have asphalt shingle roofing that responds well to treatment. Flat or built-up roofing common on some Specials is assessed separately.
Assessment includes checking moss coverage, and treatment includes a hydrophobic nano-coating that helps prevent new moss establishment after existing moss and debris are cleared.
Yes — reach out with your building details and we'll assess whether GoNano treatment is a fit for your strata's roofing.
Free assessments are usually scheduled within a few days, and treatment itself takes 2–4 hours for most residential roofs, completed in one visit.
