Does this fix my roof moss problem?

It does not replace a cleaning. Existing moss has to come off first. Once the surface is clean and dry, the treatment reduces retained water, which slows recolonization. On the coast this is recurring maintenance, not a permanent fix.

It rains constantly. When do you apply?

The surface has to be clean and dry at application, so we schedule into dry windows, mostly May through September. That is the real scheduling constraint on the coast and we account for it when quoting.

Nanoxeal surface protection in Vancouver

Vancouver takes roughly 1,200 mm of rain a year, almost all of it between October and March. The local problem is not frost, it is water that never fully dries. Nanoxeal is a water-based coating that keeps exterior surfaces shedding water through that season.

What the Lower Mainland climate does to surfaces

A six-month rainy season that keeps surfaces permanently damp
Moss, algae and lichen colonizing roofs shaded by conifers
Salt air off the Strait of Georgia on anything metal near the water
Little frost, so damage comes from trapped moisture rather than freeze-thaw

Nanoxeal in Vancouver

Immediate beading that rolls water off instead of letting it soak in
Breathable membrane: essential here, because a sealing film would trap moisture
Slows moss returning on surfaces that have been cleaned and treated

The coverage (1,000 to 1,200 sq ft per 19 L pail, two coats) and the protection duration (up to 15 years) are the manufacturer specification, not independent lab results. Always test a small area before treating the whole surface.
