Algae and moss are
more than an eyesore.

🌿
Roof Damage

Algae and moss trap moisture against your shingles, breaking them down early and shortening your roof's lifespan.

🏚️
Curb Appeal & Resale

Black streaks and staining are one of the first things buyers and neighbours notice — soft washing restores a clean, well-kept look fast.

🦠
Mould & Mildew Spread

Left untreated, mildew on siding can spread toward window frames, trim, and eventually indoors.

🔨
Pressure Washing Damage

High-pressure washing can strip paint, crack stucco, or force water under shingles. Soft washing gets the same results without the risk.

🐝
Pest Attraction

Algae and organic buildup attract insects and pests looking for moisture and shelter along your roofline.

🏠
Warranty Protection

Many roofing manufacturers recommend low-pressure cleaning only — pressure washing can void shingle warranties.

Soft washing,
answered.

Soft washing uses low water pressure combined with a specialized, biodegradable cleaning solution to break down algae, moss, mildew, and grime — then rinses it away. It's a gentler alternative to pressure washing that's safe for roofs, siding, and other delicate surfaces.

Pressure washing relies on high water pressure alone, which can strip paint, crack stucco, or damage shingles. Soft washing uses low pressure and a cleaning solution to do the work instead, giving you the same clean without the risk of surface damage.

Yes — soft washing is the recommended method for asphalt shingle roofs. High-pressure washing can lift or damage shingles and even void some roofing warranties, while soft washing safely removes algae and moss without that risk.

Most Calgary homes benefit from a soft wash every 1–2 years, though homes with heavy tree cover or shaded, north-facing rooflines may need more frequent treatment due to faster algae and moss growth.

Yes — we use biodegradable, eco-conscious cleaning solutions and take care to protect your landscaping during the wash. Plants and pets are safe around the area once surfaces have been rinsed.

No — you don't need to be home. We just need access to the exterior of your property. We'll send a text when we arrive and when we're done, with photos if any issues come up.

We serve all quadrants of Calgary — NW, SW, SE, and NE — plus surrounding communities including Airdrie, Cochrane, Chestermere, and Okotoks. Not sure if you're in our area? Give us a call at 587-324-7513.
