Winter Is One of the Best Times to Treat — Nanaimo, Central Vancouver Island
Winter treatment is viable year-round on Vancouver Island — temperatures above 5°C (common even in January from Victoria to Nanaimo) allow biocide to remain effective. 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. Roof Labs Canada operates year-round with no winter shutdown — rain-free window applications achieve full results and the damp winter surface actually improves biocide absorption.

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.
