The Repair-vs-Replace Question for Homeowners in Hull, Aylmer, and Ottawa
For homeowners in Hull, Aylmer, Gatineau, and Ottawa, the decision between roof repair and full replacement is one of the most significant home maintenance decisions they will face. Cossette Roofing has been inspecting, repairing, and replacing roofs across the Hull-Aylmer-Ottawa corridor since 2005.
Signs That Targeted Repair Is Sufficient
Repair is appropriate when: one to five shingles are missing or visibly damaged after a windstorm; a single flashing has separated or corroded; caulking around a penetration has failed; a small section of elastomeric membrane has cracked or the seam has opened; soffit or fascia damage is isolated; or the roof is under 15 years old and in otherwise good condition.
Signs That Full Roof Replacement Is Needed
Full replacement is warranted when: shingles are 20 to 25+ years old with widespread curling, cupping, or granule loss; bald patches are visible across multiple roof sections; multiple areas are leaking or have leaked over the past 2–3 years; the roof deck has soft spots; shingles are breaking apart during inspection; the existing roof has two or more layers already installed; or attic inspection reveals widespread moisture staining, mould, or insulation saturation.
The Role of the Attic Inspection in Hull and Aylmer Homes
The underside of the roof deck tells the true story of how the roofing system has performed. Cossette roofers inspect attics for: black staining or mould on rafters and sheathing; daylight visible through the deck; insulation that is compressed, wet, or has fallen away; and inadequate ventilation — a common cause of premature shingle failure in Hull and Aylmer homes built before 2000.

Frequently Asked Questions
Can I see my roof from the ground to assess its condition?
A ground-level visual check is a useful first step — look for missing shingles, sagging areas, dark staining, or gutters full of granules. However, many problems are only visible from the roof surface itself or from inside the attic. A professional inspection by a certified Cossette roofer is the most reliable assessment.
How much does a roof repair cost in Hull or Aylmer?
Minor repairs typically range from a few hundred dollars for a single flashing replacement or shingle patch to several thousand dollars for a larger deck section or multi-area repair. Cossette provides free, written estimates for all repair work — call 819-777-7177 to schedule.
