Cossette Roofing installs and replaces siding on homes, condominiums, and commercial buildings across Gatineau, Ottawa, and the Outaouais [CONFIRM materials offered — e.g. vinyl, aluminum, engineered wood]. Siding is the building’s outer skin: it sheds rain and snow off the walls, protects the structure and insulation behind it, and sets how the property looks from the street. Cossette has worked on building exteriors across the National Capital Region since 2005 and holds RBQ License 5697-7788-01.

Siding is the wall’s weather barrier and its finished face in one. It sheds rain and meltwater down and away from the sheathing, shields the insulation from wind and moisture, and closes the walls against insects and rodents. When siding fails, the damage rarely stays cosmetic — water gets behind the panels, soaks the sheathing, and travels into the wall cavity where it feeds rot and mould long before anything shows on the surface.
The same climate that kills gutters and fascia works on siding: freeze-thaw. Water that gets behind or between panels freezes overnight and expands, opening joints a little wider every cycle. Add road salt spray near driveways and streets, UV exposure that turns older vinyl brittle, and the impact load of ice sliding off rooflines, and siding in the National Capital Region ages faster than the same product would in a milder climate. That is why the details — flashing, overlaps, and the junctions at the roofline — matter more here than the panel brand.
The most vulnerable line on the whole wall is where the siding meets the roof: at gable ends, along step flashing, and under the soffit. Water that escapes the roof edge runs straight into that junction. Cossette works both sides of that line — the roof above and the wall below — which is why siding, soffit, and fascia are quoted as one exterior envelope when more than one of them needs work.
Replace siding when panels are cracked, warped, loose, or letting water reach the wall behind them — repainting or re-nailing failing siding treats the symptom, not the leak. A Cossette estimator checks for:
Isolated storm damage on otherwise sound siding can be repaired panel-by-panel. Once cracking or buckling shows on several walls, the material has aged out and section patching becomes a repeating cost — replacement is the honest fix.
Replace soffit and fascia when the boards are soft, stained, peeling, or pulling away from the roofline — these are symptoms of water already getting in, not cosmetic wear. These are the signs a Cossette estimator looks for during the free evaluation:
Rotted fascia is repaired or replaced before any new eavestrough goes up. A gutter is only as secure as the board it hangs on, and hanging new aluminum on failed fascia is the most common reason a replacement sags within two years.
Every job is quoted and installed as a complete roof-edge assembly, not a panel swap. Each component is specified for the building:
Cossette follows the same four-step process on soffit and fascia work as on roofing work:
Because soffit and fascia are part of the roof, not the siding. The drip edge, starter course, fascia, soffit, and eavestrough all meet in the same few inches of the building, and that junction is where most eave leaks actually begin. A siding or gutter-only crew installs to the fascia and stops there. Cossette assesses the whole assembly, because the same team is responsible for the roof above it.
Call 819-777-7177 or request a quote online. A Cossette estimator visits the property, measures every run, checks the condition of the fascia and roof edge, and identifies where water is currently going wrong.
You receive a written estimate covering trough profile and colour, the number and placement of downspouts, hanger spacing, and any fascia repair required before installation. No hidden fees.
The aluminum is roll-formed on your property to the exact length of each run, then hung on heavy-duty hidden hangers and pitched toward the outlets so water moves instead of standing. Downspouts are fastened to the wall and the discharge is directed away from the foundation.
The crew checks the flow, confirms slope and discharge, and clears every offcut, fastener, and length of scrap from the property before leaving.
Cossette installs soffit and fascia across the National Capital Region from two offices: 14 Rue Buteau, Gatineau, QC J8Z 1X4 and 201-117 Murray Street, Ottawa, ON K1N 5M5. Because the company is licensed and insured for work on both sides of the Ottawa River, property owners get the same crew and the same coverage regardless of province.

Soffit is the horizontal panel under the roof overhang; fascia is the vertical board at the roof edge that the eavestrough attaches to. Soffit ventilates and seals the underside of the eave, while fascia caps the rafter ends and carries the weight of the gutter system.
Staining on the soffit almost always means water is running behind the eavestrough instead of into it — from a failed gutter seam, wrong slope, or a roof-edge leak. The stain is the symptom; the fix is at the roof edge above it, which is why Cossette inspects the whole assembly rather than just replacing the panel.
Yes — in almost every home, the soffit is the attic’s air intake. Vented (perforated) panels pull cool outside air into the attic, which exits at the ridge or roof vents. Cossette calculates how much of the soffit run should be vented panel so intake matches exhaust. [CONFIRM]
They are one of the main causes. Without intake air, the attic warms the roof deck, snow melts from underneath and refreezes at the cold eave, and the resulting ice ridge forces water back under the shingles. Clear, properly sized soffit ventilation keeps the roof deck cold so snow melts evenly.
Yes. Soffit and fascia are replaced on their own all the time — most often when the boards have rotted, panels have blown loose, or pests have gotten in. If the roof is due within a few years, Cossette will tell you during the evaluation so the work can be sequenced sensibly.
When more than one of them is failing, yes. They occupy the same few inches of roof edge, so replacing them together means the assembly is rebuilt as one system, the edge is only opened up once, and new gutters are hung on sound fascia instead of rotted board.
Cossette installs factory-finished aluminum. Aluminum does not rust — which matters in a climate with heavy snow, road salt, and repeated freeze-thaw cycles — and the baked finish is colour-stable, so it never needs painting. [CONFIRM: aluminum only, or vinyl also offered?]
The cost depends on the total length of the roofline, the number of storeys, how much fascia board needs replacing, and whether eavestroughs are being redone at the same time. Cossette provides a free, no-obligation written estimate for every project in Gatineau, Ottawa, and the Outaouais. Call 819-777-7177.
Peeling or bubbling paint along the roofline, wood that feels soft when pressed, gutter spikes or hangers pulling loose, and dark staining behind the eavestrough. If the eavestrough is sagging, the fascia behind it has usually already failed.
Yes — gaps and sagging soffit panels are one of the most common entry points for squirrels, birds, wasps, and bats. New aluminum soffit closes the roof cavity with panels locked into continuous trim channels, leaving no loose edges to pry open.
Yes. Cossette Roofing holds RBQ License 5697-7788-01 issued by the Régie du bâtiment du Québec, has been BBB-accredited since August 2020, and carries full liability insurance on all work. The company has operated in Gatineau, Ottawa, and the Outaouais since 2005.
Call 819-777-7177 or request a quote at toiturescossette.ca. A Cossette estimator visits the property, inspects the roofline and attic ventilation, and provides a detailed written estimate with no obligation.
Soffit ventilates your attic and seals the roof overhang; fascia carries your eavestroughs. When either one is stained, soft, or sagging, water or pests are already getting in — and blocked soffit is a root cause of the ice dams this region fights every March. Cossette Roofing has rebuilt roof edges across Gatineau, Ottawa, and the Outaouais since 2005, RBQ-licensed and BBB-accredited, and treats soffit, fascia, drip edge, and eavestrough as one assembly.
