What's different about roof cleaning and repair in London

London, ON winters average a nightly low near -9.1°C in January with 194 cm of annual snowfall, and freeze-thaw cycles combined with lake-effect squalls are common; summers reach about 26.6°C in July, with annual precipitation around 1,011.5 mm. That cycle of snow load, freezing, and thawing leaves moss and algae plenty of moisture to take hold on local roofs. Housing here ranges from Victorian and Edwardian character homes in Old North, Wortley Village, and Old East Village, built before the 1930s, to newer post-war and 1990s-2010s subdivisions in neighborhoods like Byron and Sunningdale — different roof ages and slopes that call for different cleaning approaches.

Roof cleaning is unlicensed exterior-maintenance work in Ontario — no specialty trade license is required, though reputable crews carry liability insurance and follow fall-protection practices for steep or wet roofs. If cleaning turns up damaged shingles, flashing, or structural issues, that repair work should go to a licensed general contractor or roofing contractor, and any electrical problem uncovered along the way should be referred to a licensed electrician. The best window to book is late summer, July through September, when moss and algae are driest and easiest to kill — treating then gets ahead of the fall rains that feed regrowth before winter's freeze-thaw cycle sets in again.

What moves the price in London

Steep-pitched Victorian roofs in Old North and Wortley Village need harness/roof-jack work, raising labor time.
194 cm of annual snowfall and freeze-thaw cycles push moss growth on shaded London roofs.
Newer subdivisions in Byron and Sunningdale often have simpler roof lines, meaning shorter cleaning jobs.
Roof repair beyond cleaning needs a licensed general or roofing contractor under Ontario's rules.

Licensing and permits in Ontario

Roof cleaning itself is unlicensed exterior-maintenance work in most US states and Canadian provinces (no specialty trade license required, though liability insurance and fall-protection compliance are standard for reputable crews); actual roof REPAIR work should be handled by a licensed general contractor or roofing contractor, and any electrical or structural issue uncovered during a job should be referred to the relevant licensed trade.

Residential building permits in Ontario are issued by the local municipality's building department under the Ontario Building Code (not by the province directly), so exact triggers vary somewhat city to city. In London, permits come from the City of London Building Division.

Tax: HST applies to labor on home repair and improvement services in Ontario — unlike some US states, there's no separate labor exemption, so a contractor charges 13% HST on both materials and labor for taxable home-service work.

Best time to book in London

Book in late summer (July-September): moss and algae are driest and easiest to kill, and treatment gets ahead of the fall rains that feed regrowth. Peak demand: July, August and September. Typical job length: 2-5 hours.

DIY or pro? Light DIY rinsing with a garden-hose-mounted cleaner can knock back mild surface algae, but moss removal, harness/roof-jack work on steep pitches, and any pressure washing are best left to a pro to avoid shingle damage, warranty voidance, or falls.
