Professional roof moss control
Moss, algae, and organic growth trap moisture against roofing materials, accelerating wear and deterioration. Left untreated, moss can lift shingles, retain water, block drainage paths, and shorten the lifespan of the roof.
Without routine moss control, properties face increased risk of leaks, premature shingle failure, and costly repairs. Our roof moss removal and treatment service focuses on safely controlling organic growth, preserving roofing materials, and protecting the structure — not just improving appearance.

Heavier moss growth is carefully removed by hand using controlled methods that avoid damaging shingles or roofing materials. We do not use aggressive scraping or pressure washing.

After removal, roof surfaces, valleys, and transitions are cleared of loose debris to prepare the roof for treatment and ensure proper drainage.

A professional, roof-safe treatment is applied to eliminate remaining spores and slow regrowth. Treatments are selected based on roof type and environmental conditions.
We protect roofing systems — not shorten their lifespan.
Please reach us at info@islandersom.ca if you cannot find an answer to your question.
Most roofs benefit from moss treatment every 1–2 years, depending on tree coverage, roof orientation, and moisture exposure.
No. We do not pressure wash roofs. High pressure can damage shingles and void warranties. Our methods are roof-safe and material-appropriate.
Yes, when done properly. We use controlled hand removal and treatments designed specifically for asphalt shingles and other roofing materials.
Moss treatment significantly slows regrowth, but Vancouver Island’s climate means ongoing maintenance is necessary. We’ll advise on realistic treatment intervals.
Yes. We service residential, strata, and commercial roofs, including scheduled maintenance programs for managed properties.
Roof access carries risk if done improperly. Our crews use proper safety procedures, access methods, and training to manage height and roof conditions safely.
All debris is contained and cleaned up from the work area. Properties are left tidy and professional.
Every roof is different. We assess roof condition, material type, slope, access, moss coverage, drainage paths, and safety considerations before recommending service or treatment schedules. Assessments are structured, documented, and obligation-free.
