Do you have questions about your flat roof? We invite you to explore this section to find clear answers about flat roof maintenance, repair, and installation. If you can’t find the information you’re looking for, our team will be happy to assist you.
How long does an elastomeric membrane flat roof last?
An elastomeric membrane flat roof in an urban environment can last between 20 and 30 years when properly installed and maintained. Installation quality, weather exposure, and inspection frequency all have a direct impact on its lifespan.
How often should a flat roof be inspected?
We recommend an annual flat roof inspection for residential buildings. For commercial properties or roofs exposed to higher wear, biannual inspections are preferable to prevent leaks and maintain optimal system performance.
What are the signs that a flat roof needs repair?
Water infiltration, ceiling stains, weakened seams, or a cracked membrane are common warning signs. Poor drainage can also indicate an issue. We always perform a complete roof inspection and diagnosis before any repair work.
Do you offer 24/7 emergency flat roof repair in Montreal?
Yes. Toitures J.S.B. offers 24/7 emergency flat roof repair services in Montreal, Laval, and the North Shore. We respond quickly to secure the roof and limit damage, then plan the appropriate repair based on the situation.
Do you repair asphalt and gravel built-up flat roofs?
Yes. We repair built-up roofing systems (asphalt and gravel flat roofs). In some cases, we perform temporary repairs using specialized sealants or membrane patches to stabilize the affected area.
Do you install new flat roofing systems?
Yes. We install new flat roofing systems using elastomeric membranes for residential and commercial buildings in Montreal. Each project is planned based on the building structure, insulation requirements, and applicable standards.
What is the difference between flat roof repair and replacement?
A repair addresses a localized issue. A roof replacement (re-roofing) involves partial or full replacement of the roofing system when the membrane reaches the end of its service life. We recommend the most suitable option following a detailed inspection.
When should a flat roof be replaced?
A roof replacement is recommended when repairs become frequent or when the membrane shows advanced wear. An inspection helps determine whether replacement is the most cost-effective solution in the medium term.
How much does flat roof repair cost in Montreal?
The cost depends on the roof size, accessibility, and extent of the damage. An on-site evaluation is required to provide an accurate diagnosis and recommend the most appropriate solution.
Do you work on commercial and industrial buildings?
Yes. We repair, maintain, and install flat roofing systems on various types of buildings, including multi-unit properties, retail spaces, and light industrial facilities. Our work is carefully planned to minimize disruption to your operations.
Does maintenance really extend the lifespan of a flat roof?
Yes. Regular flat roof maintenance, including drain cleaning, seam inspection, and sealant checks, helps prevent leaks and extend the lifespan of your elastomeric membrane roofing system.
What type of membrane do you use for flat roofs?
We work with SOPREMA elastomeric membranes, known for their reliability in Quebec’s climate. The choice of system depends on the type of building and the specific requirements of the project.
Does a leak mean the roof needs to be replaced?
No. A leak can sometimes be resolved with a targeted repair. However, if the membrane has reached the end of its service life, a full roof replacement may be more appropriate. An inspection will determine the best option for your situation.
How long does a flat roof replacement take?
The timeline varies depending on the size and complexity of the project. For a residential plex, work may take a few days, while commercial projects often require more extensive planning.
Do you offer flat roof maintenance plans in Montreal?
Yes. We offer customized flat roof maintenance plans that include one to four visits per year. These programs cover inspections, drain cleaning, seam checks, and targeted adjustments when needed.
