Montreal, QC · Roofing & Waterproofing
The 25 Best-Rated Roofing & Waterproofing in Montreal
Ranked from 83 operating roofing & waterproofing businesses in Montreal, QC that carry at least 20 Google reviews. Updated 2026-08-19.
How this is ranked
By Google rating, weighted by how many reviews it rests on. A rating is pulled toward the local average (4.79 across the 83 businesses considered) in proportion to how thin its review count is, so a lone 5.0 from 20 reviews cannot outrank a 4.8 from 900. No payment, placement or editorial judgement affects the order, and businesses that have claimed their listing get no lift — the mark below only says the listing has an owner behind it.
