At ClearView Home Services, we’ve seen firsthand how roof washing in British Columbia can protect homes from costly repairs and extend roof life. Moss, algae, and debris don’t just make your roof look tired—they threaten its integrity.
Professional roof washing in British Columbia isn’t just about appearances. It’s a smart, preventative investment in your home’s health.
What Grows on Your Roof in British Columbia — And Why It’s a Problem
BC’s wet climate creates the perfect breeding ground for organic roof invaders. Left untreated, these issues snowball into expensive damage.
🟢 Moss
Lifts shingles, traps moisture, and accelerates wood rot.
⚫ Algae
Leaves black streaks, weakens shingles, and promotes early breakdown.
⚪ Lichen & Mold
Feeds on roofing surfaces, slowly degrading materials.
🍂 Debris
Pine needles and leaves trap water, promote moss, and attract pests.
Ignoring these problems can reduce your roof’s lifespan by up to 30%.
Why You Should Avoid DIY Roof Washing in BC
DIY roof washing might look cost-effective—but it can backfire fast.
-
🧨 High-pressure washers void warranties and damage shingles
-
🌊 Water forced under shingles can cause interior leaks
-
🔁 DIY treatments often fail to kill spores, meaning fast regrowth
At ClearView, our techs are trained, certified, and insured. We follow WorkSafeBC safety protocols and use professional soft wash systems that get results—safely.
🔁 Ongoing Maintenance Plan
-
Apply roof treatment every 2.5 to 4 years
-
Prevents moss from regrowing
-
Extends roof life without repeated full washes
Factors that affect timing:
-
Tree coverage
-
Shade exposure
-
Roof material
-
History of algae/moss buildup
Combine with annual gutter cleaning for best results.
