Complete preventive service for residential & commercial properties
➡️ In case of a flat roof emergency in Montreal, our team is available 24/7 to respond quickly. We limit damage and implement effective solutions to secure your roofing system.
Elastomeric membrane flat roofs are a key part of Montreal’s urban landscape. At Toitures J.S.B., we provide complete flat roof inspection and maintenance services in Montreal for both residential and commercial buildings. Our main objective is to preserve waterproofing, extend the lifespan of your roofing system, and reduce the risk of emergency repairs.
A service tailored to Greater Montreal
Montreal’s building stock includes plexes, townhouses, multi-unit buildings, retail spaces, and office buildings. We adapt each flat roof maintenance plan based on surface area, roof configuration, and the presence of rooftop equipment.
In Quebec, flat roofs are exposed to major climate variations, as well as snow and water accumulation. Our roofing teams work with precision to ensure occupant safety, minimize disruption to your operations, and maintain optimal performance of your elastomeric membrane roofing system.
Maintenance plan for elastomeric membrane flat roofs
At Toitures J.S.B., we offer customized maintenance plans for elastomeric membrane flat roofs in Montreal. Depending on the condition of your roof and your needs, we recommend annual or biannual inspections to quickly detect issues and prevent major repairs.
Our programs typically include one to four visits per year. Frequency can be adjusted based on welded seams, flashing details, vertical upstands, and higher-risk areas. Each visit includes a thorough inspection and targeted recommendations.
A well-structured maintenance plan allows for preventive rather than corrective interventions. We handle necessary adjustments and ensure consistent monitoring of your flat roof over time.
Annual or biannual flat roof inspection
During each flat roof inspection in Montreal, our roofers perform a complete visual assessment of the elastomeric membrane. We evaluate the overall condition, adhesion, welded seams, vertical flashings, and transitions around mechanical equipment.
Special attention is given to sealants, flashings, and perimeter details. We check for cracks, lifting, and premature wear. This process allows us to identify necessary repairs before water infiltration occurs.
For commercial buildings, where surfaces are larger and mechanical systems more numerous, we recommend biannual inspections to better manage risk and ensure operational continuity.
Thermographic flat roof inspection in Montreal
Thermographic inspection is an effective, non-invasive method to detect hidden issues. At Toitures J.S.B., we use infrared thermography to analyze flat roofs and identify water infiltration, moisture zones, and heat loss, even when invisible to the naked eye.
This technology allows us to target specific problem areas, avoiding unnecessary work across the entire roof. Particularly relevant in Quebec’s climate, thermographic inspections help extend roof lifespan and optimize maintenance strategies.
Routine elastomeric membrane maintenance
Flat roof maintenance includes cleaning drains and downspouts to ensure proper water flow. Our roofing specialists remove debris and verify effective drainage across the entire surface.
Welded seams are inspected for strength, and localized adjustments are performed when needed. We also check sealants around penetrations, vents, and rooftop equipment. If required, targeted repairs are carried out to reinforce vulnerable areas.
Repairs and preventive follow-up
If an issue is detected during inspection, we provide repair solutions adapted to your elastomeric membrane system. Our work addresses problems at the source without requiring full roof replacement.
All inspection and maintenance interventions are documented to ensure consistent year-over-year follow-up. This is particularly valuable for rental properties, condominiums, and commercial buildings across Greater Montreal.
Why trust Toitures J.S.B. with your maintenance?
Flat roofs are exposed to multiple constraints, including highly variable weather conditions. Regular maintenance reduces the risk of water infiltration and protects both insulation and structural components.
