Roofer in Repentigny

Roofs in Repentigny

Much of Repentigny was built in the 1970s and 1980s, with bungalows, split-levels and cottages under asphalt shingles that are often on their second covering. The Le Gardeur sector, now part of Repentigny, adds neighbourhoods from different eras, while the riverfront has older homes alongside newer condo buildings. Shopping centres and buildings along the main boulevards have large flat membrane roofs.

What we run into on Repentigny roofs

• 1970s bungalows whose second layer of shingles is starting to wave because it follows every bump in the layer underneath.
• Aluminum roof vents dented by hail or branches, with flaps that no longer close and let powder snow blow in.
• Near the river, loose ridge caps and bare rake edges on houses that take the wind head-on.
• On condo buildings and stores along the main boulevards, flat-roof membranes with seams lifting around drains and mechanical units.
• In the Le Gardeur sector, houses extended at different times, with roof sections that don't drain in the same direction.

Two layers of shingles on a bungalow: repair or start over?

In Repentigny neighbourhoods built in the 1970s and 1980s, it's common for a second layer of shingles to have gone on over the first at the first replacement. It saved on tear-off, but that second layer often wears faster: it runs hotter, takes on the shape of the old layer and can't be cleanly repaired one shingle at a time. Once it's done, both layers have to come off, right down to the deck.

That full tear-off is also the chance to fix what the overlay was hiding: damaged decking, no membrane along the eaves, original flashing that was never changed, not enough ventilation. We lay those items out plainly in the quote. On riverfront homes we pay extra attention to nailing along the rakes and to a well-anchored ridge vent, since that's where the wind off the river hits first.

Winter in Repentigny

On properties along the river, winter wind comes in unobstructed and tests the roof, especially along ridges and edges. Repeated freeze-thaw cycles in spring, together with moisture off the river, keep flashing and chimney seals working hard.
