Roof Cleaning Scams in BC
Common Deceptive Practices and How Vancouver Island Homeowners Can Protect Themselves
Roof cleaning scams are more common on Vancouver Island than homeowners realise — and they're often difficult to identify until months after the work is done. The scams range from outright fraud (taking payment and not performing work) to subtler deceptions (performing damaging work at professional prices). This guide identifies the most common patterns.
The "Pressure Wash and Go" Scam
The most common roof cleaning scam on Vancouver Island: a contractor quotes professional biocide treatment pricing ($500–$900) and delivers a 30-minute pressure wash that visibly removes moss but causes significant shingle damage and guarantees regrowth within 60 days. The homeowner pays full price for a service that: caused permanent granule loss, didn't kill the moss biology, and will require retreatment within 3 months. By the time the moss returns, the contractor is unreachable. How to prevent it: ask specifically about PSI, ask to see their chemical product, and get a written 2-year guarantee in the contract.
The "Roof Replacement Scare" Scam
A contractor arrives for a moss treatment quote and tells the homeowner their roof needs replacement, not treatment — generating a reroofing quote worth $15,000–$25,000. While legitimate roofing contractors do identify genuine replacement needs, this tactic is sometimes used dishonestly to generate higher-value work. If you receive a replacement recommendation from a moss treatment company, get a second opinion from an independent certified roofing inspector. On Vancouver Island, most roofs with heavy moss can be successfully treated and maintained for years before replacement is genuinely needed.
The "Long-Term Guarantee" That Isn't
Some contractors offer 5-year or 10-year guarantees to win business — guarantees they have no intention of honouring. Warning signs: the guarantee isn't in writing; the company has no verifiable fixed business address; payment was required in full before work began. A legitimate guarantee is worth only as much as the company standing behind it. Roof Labs Canada's 2-year written guarantee is supported by our established business history since 2015, verifiable address, and trackable customer history.
Frequently Asked Questions
What recourse do I have if I've been scammed by a roof cleaner?
File a complaint with Consumer Protection BC (for unlicensed contractors) and the BC Better Business Bureau. If the contractor is licensed, you can file a complaint with the BC Registrar of Companies. For damage resulting from poor workmanship, the contractor's liability coverage may be claimable — request their certificate of coverage.
