Roof leak repair in Repentigny

Before repairing anything, we need to know whether the water is coming from outside or from the house itself. We compare where the stain is with how the roof is oriented, inspect the attic and follow every duct that runs through the roof. Whether you're in Old Repentigny, the Le Gardeur sector or on a riverside street, the approach is the same: find the entry point, then close it for good.

When wind off the river drives rain under the shingles

A shingle roof is designed for water to run down the slope. When a strong gust pushes it upward or sideways, it can pass under a course whose sealant strip has let go, get in through a gap in the ridge vent or slip behind dormer flashing. On houses facing the water, these leaks almost always happen on the exposed slope, during fall storms or spring downpours.

The signs indoors are typical: a ring high on a wall, a drip from a light fixture near an outside wall, water on an upstairs window sill. We match those clues with the wind direction during each episode to target the right side of the roof. Once the entry point is confirmed, we reseal or replace the affected courses and add fastening along that exposed slope so the next gust can't lift them again.

False leaks: ducts dripping in the attic

In many Repentigny bungalows and split-levels, the bathroom fan or the kitchen range hood has been replaced over the years. If the duct came loose, isn't insulated or ends in the attic instead of exiting through the roof, warm, moist air condenses in winter and runs out on the first mild day. It looks like a roof leak, but no shingle is involved. We reconnect and insulate the duct all the way to a sealed roof outlet, which fixes the problem at the source.

• Drips around the bathroom fan grille
• A flexible duct that's crushed, disconnected or lying in the insulation
• Frost concentrated in one spot in the attic
• An exhaust cap with no damper, or one stuck open

A clear answer, even mid-storm

If water is coming in during a storm, our emergency service can put on temporary protection to limit the damage, then come back for the permanent repair when the weather allows. For a less pressing leak, we book a visit quickly. Afterwards you get a photo report showing the stain, the path the water took and the entry point, followed by a free written quote within 24 hours that sets out the recommended repair and what it includes.
