If you’ve noticed moss starting to form on your roof, don’t wait until it takes over. Moss holds moisture, spreads quickly, and can make a roof look older than it really is.
In the Fraser Valley, long damp stretches and shaded areas create perfect conditions for moss growth, especially on north-facing slopes and homes near trees. Early spring is a great time to remove winter moisture-related buildup and stop growth before it expands, while late spring through early fall tends to offer the most consistent drying conditions for scheduling.
The simplest rule: anytime you see moss actively spreading is a good time to address it — waiting usually just makes removal harder and the buildup heavier.
