Summer Is the Best Preventive Window — Nanaimo, Central Vancouver Island
Summer is the lowest biological activity season on Vancouver Island — making it the best time for preventive treatment on clean roofs before fall's wet season restarts moss growth. In Nanaimo, Nanaimo's 1,200mm annual rainfall makes fall treatment particularly important — winter rain events from November–February are the primary driver of moss accumulation on untreated roofs. Summer application on a clean or lightly affected roof extends the treatment interval significantly — UV exposure helps break down treated organisms before fall rain washes them clear.

Light rain during or shortly after application is not a problem — biocide bonds to shingle surfaces within 1–2 hours. Heavy rain within 30 minutes of application may dilute the initial treatment. Roof Labs Canada monitors weather and reschedules if necessary.
