Moss & Algae Treatment

Roof Moss Removal & Soft Wash Cleaning for BC Homes

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.

Why Moss Destroys BC Roofs

Root Penetration

Moss rhizoids (roots) physically penetrate shingle surfaces, breaking down the asphalt matrix and lifting shingle edges.

Moisture Retention

Moss acts like a sponge — holding water against your shingles for days after rain, accelerating rot and freeze-thaw damage.

Granule Loss

As moss grows and is removed, it tears away the protective granule layer — the shingle's primary UV shield.

Blocked Drainage

Thick moss mats block gutters and valleys, causing water to back up under shingles and into your roof deck.

Algae Staining

Black algae (Gloeocapsa magma) feeds on limestone in shingles, causing dark streaks and accelerating deterioration.

Voided Warranties

Most shingle manufacturers void warranties when moss or algae damage is present and untreated.

Our Moss Removal Process

1

Inspection & Assessment

We assess moss coverage, shingle condition, and drainage. You get an honest report before any work begins.

2

Safe Removal

Moss is treated with a biodegradable solution and carefully removed — no high-pressure washing that damages shingles.

3

GoNano Protection

After removal, GoNano treatment restores shingle health and creates a hydrophobic surface that resists future moss growth.

Moss Removal FAQs

Can I pressure wash moss off my roof?

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.

Will moss come back after removal?

Without treatment, yes — BC's climate guarantees it. GoNano's hydrophobic surface significantly slows regrowth. Zinc strips at the ridge also help.

How do I know if my roof has moss damage?

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.

Does moss removal work with roof rejuvenation?

Yes — and it's the ideal combination. Moss removal clears the surface, then GoNano treatment restores the shingle and protects against future growth.

Moss on my roof — how do I fix it without replacing the whole roof?

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.

Roof granules are falling off — what can I do?

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. Book a free inspection — we'll tell you honestly whether your roof is still in the treatment window.
