What commercial membrane systems dominate the Laval market?
SBS-modified bitumen membranes, produced locally by SOPREMA and distributed through the regional supply chain, are the most commonly specified system on Laval's commercial buildings. The SBS modifier maintains membrane flexibility at the extreme cold temperatures Quebec experiences, which APP-modified systems do not match below certain thresholds. Two-ply systems with a base sheet and reinforced cap sheet provide redundancy against the seam stress that thermal cycling generates over a roof's service life.
Does a commercial roofing project in Laval require an RBQ licence?
Yes. Any contractor performing commercial construction or renovation work in Quebec—including roofing—must hold an active RBQ licence-entrepreneur and must display the licence number on all contracts and advertising. The RBQ number can be verified on the RBQ's public registry. Laval property owners should also confirm that the contractor's coverage under the Plan de garantie or RBQ warranty program applies to commercial work, as the residential guarantee plan does not cover commercial-use buildings.
How should commercial flat roofs in Laval be maintained through the winter season?
Snow removal from commercial flat roofs in Laval is not optional in heavy accumulation years—structural load limits can be reached during multi-storm sequences in January and February. Reputable contractors offer snow removal services as part of annual maintenance agreements and can assess load conditions when snowpack depth is uncertain. Drain inspection and clearing after the spring thaw is equally important, as sediment and ice debris accumulate around internal drains during the melt season and cause ponding on newly cleared membranes.
