Roof Cleaning & Moss Removal in Port Alberni

Why moss builds up on Alberni Valley roofs

Moss grows fast on shaded, damp roof sections. North slopes and areas under overhanging trees gather thick moss quickly. Moss traps moisture right against your shingles. As it thickens, it lifts shingle tabs and lets rain work underneath. Homes around Sproat Lake, Beaver Creek and Cherry Creek with heavier tree cover tend to see more moss than roofs closer to open ground in town.

How we remove moss without damaging the roof

We scrape moss and debris off your roof by hand from the ridge down. We never use a pressure washer because high pressure strips protective shingle granules. We treat metal panels and flat roof membranes with specific cleaning methods. We adapt our approach to match your exact roofing material. If we see soft decking or loose shingles while cleaning, we let you know right away. We can provide a separate price for roof repairs and leaks.

How we clean a roof and remove moss

1. 1

   Inspection — we check the roof for moss, algae staining, debris and any early signs of damage.

2. 2

   Debris removal — we clear leaves, needles and moss by hand, working from the ridge down.

3. 3

   Rinse & treatment — we rinse the roof at low pressure and treat it to slow new moss growth.

4. 4

   Report back — we let you know if we found anything, like lifted shingles or soft decking, worth a closer look.

What does Port Alberni's climate mean for this job?

Heavy tree cover across Sproat Lake, Beaver Creek and Cherry Creek helps moss grow quickly. North-facing roof slopes take the brunt of that growth. Regular cleaning keeps moss from working under your shingle tabs. That stretches out the time between re-roofing jobs. We schedule roof cleaning during dry weather. Dry shingles give our crew safe footing while working on steep slopes.
