BC's wet climate is perfect for moss and algae — and devastating for asphalt shingles. Left untreated, moss roots lift shingles, trap moisture, and accelerate granule loss. We remove it safely and protect your roof from regrowth.
Book Free Moss AssessmentMoss rhizoids (roots) physically penetrate shingle surfaces, breaking down the asphalt matrix and lifting shingle edges.
Moss acts like a sponge — holding water against your shingles for days after rain, accelerating rot and freeze-thaw damage.
As moss grows and is removed, it tears away the protective granule layer — the shingle's primary UV shield.
Thick moss mats block gutters and valleys, causing water to back up under shingles and into your roof deck.
Black algae (Gloeocapsa magma) feeds on limestone in shingles, causing dark streaks and accelerating deterioration.
Most shingle manufacturers void warranties when moss or algae damage is present and untreated.
We assess moss coverage, shingle condition, and drainage. You get an honest report before any work begins.
Moss is treated with a biodegradable solution and carefully removed — no high-pressure washing that damages shingles.
After removal, GoNano treatment restores shingle health and creates a hydrophobic surface that resists future moss growth.
We strongly advise against it. High-pressure washing strips granules, voids shingle warranties, and can force water under shingles. Our low-pressure chemical treatment is far safer.
Without treatment, yes — BC's climate guarantees it. GoNano's hydrophobic surface significantly slows regrowth. Zinc strips at the ridge also help.
Look for green or black patches, lifted shingle edges, dark streaks, or granules in your gutters. Our free inspection will give you a definitive answer.
Yes — and it's the ideal combination. Moss removal clears the surface, then GoNano treatment restores the shingle and protects against future growth.
In most cases you don't need to replace your roof because of moss. Professional moss removal followed by GoNano nano-treatment clears the moss, restores your shingles, and prevents regrowth for 10–15 years — all in a single visit at a fraction of replacement cost.
Granule loss is a sign your shingles are drying out and losing their protective layer. If caught early enough, GoNano treatment can restore the asphalt binder and slow further granule loss significantly.
