About This Service

The Right Time to Replace

In Quebec, an asphalt shingle roof has a realistic lifespan of 15 à 25 ans. If your roof is approaching or past this mark, a complete replacement is often more cost-effective than repeated repairs. It's also the opportunity to improve your home's insulation, ventilation and waterproofing.

Our replacement process is methodical: complete removal of the old roofing, thorough deck inspection (and replacement of rotted sections), installation of a complete new system — membrane, underlayment, GAF shingles, flashing, drip edges and ventilation. Nothing is left to chance.

FAQ

Everything About Roof Replacement

Signs include: curling shingles, granules in gutters, recurring leaks, roof over 20 years old. If you have any doubt, our free inspection will give you a clear answer.

Techniquement possible, mais nous ne le recommandons pas. Poser par-dessus empêche d'inspecter le pontage, ajoute du poids à la structure et réduit la durée de vie de la nouvelle toiture. Nous retirons toujours l'ancien revêtement.

Not necessarily. We inspect every panel and replace only damaged sections. On average, 10-20% of the deck needs replacement.

With GAF Timberline HDZ shingles and proper installation, your new roof will last 25-30 years in Quebec and is warranted up to 50 years with Golden Pledge.
