Roofer in Carignan

Roofs in Carignan

Carignan's newer developments are mostly single-family homes with asphalt shingles, some of them already due for their first real round of flashing and vent maintenance. In the more rural areas you'll find country homes, detached garages and farm buildings, often with metal roofs that need attention to fasteners, seams and rust. Metal roofing is a popular choice here for how well it sheds snow and how long it lasts.

What we see on Carignan properties

• Metal-roofed detached garages and sheds where the screws have lost their sealing washers, so a few drops come through every time it rains.
• Poorly fastened ridge caps on metal roofs that wind-driven snow manages to lift from underneath.
• On houses built in recent years, plumbing vents and flashing that were installed in a hurry and are often the first things to need a touch-up.
• Snowdrifts that always pile onto the same slope of an outbuilding, sometimes enough to make a light frame sag.

The house and the garage: two roofs, two kinds of upkeep

On a big Carignan lot there's often a shingled house and one or two metal-roofed outbuildings, and they don't need the same care. On the house we watch the flashing, the vents and the attic ventilation. On the garage or shed it's more about the screws, the overlaps between panels, the ridge caps and rust wherever the paint got scratched. A well-kept metal roof lasts a long time, but one leaking screw left alone for a few years can rot a framing member.

For buildings where snow drifts in, pay attention to how the wind loads the roof over the winter. If the same slope fills up every year, it's worth having the framing checked and reinforced if needed before replacing the roofing. And if the house and the garage are both nearing replacement, doing them in the same season keeps things simple and gives you one clear quote for the whole property.

Winter in Carignan

Between the Richelieu and the Rivière L'Acadie, open land lets strong winds through, piling snow into drifts on certain slopes. That uneven snow load, combined with freeze-thaw cycles, is hard on older roofs and outbuildings.
