If you live in Chilliwack or Hope, you’ve probably seen it happen fast: a roof starts with a little green buildup, then before long there’s moss spreading across shingles and algae staining building up in the valleys.
That’s why roof cleaning and moss removal are such a common need in this climate. With the amount of rain, shade and moisture in the Fraser Valley, roofs stay damp longer than homeowners realize — creating ideal conditions for moss and algae to take hold.
Moss removal targets the moss growth specifically; full roof cleaning is broader and also addresses algae, lichen and general organic staining. Left untreated, either issue tends to spread and get harder (and more expensive) to deal with over time.
