Flat roof ventilation
Invest in ventilation for your roof
Roof ventilation is the key to preserving the integrity of a building and avoiding a number of problems. According to the National Building Code of Canada, all structures must ensure maximum ventilation. Manufacturers also have made it a criterion for respecting their warranties, since poor ventilation prematurely wears roof coverings. Combined with inadequate insulation, heat loss can result in ice accumulation and water seepage.
Inevitably, they will elevate the costs of heating and cooling. If necessary, our Montreal roofers will propose the solution that balances the cost of the work and the resulting performance to best protect your investment.

The ventilation of your roof is dependent on the building structure. Our technical consultants know which set-up will optimize the entire system of a ventilated roof. Their proven expertise assures an accurate diagnosis of the ventilation problem. Beforehand, they check the components in place as compared with the maximum ventilation possible. They evaluate the waterproofing, insulation, vapour barrier, the position of the air-outlet roof flaps, aerators, etc. With this information, they will be able to offer an effective solution that assures:
- Uniform airflow
- Venting of exhaust air
- Constant supply of fresh air
- Maximum efficiency of fans
- The attic is temperate
- The best positioning of the fans on the flat roof
For full effectiveness of the roof ventilation system, the choice of fans is important. For each project, our technical consultants recommend the appropriate fan according to standards and to the manufacturer’s recommendations. Among the types of fans available, Les Couvreurs Duro-Toit prefer flat-roof ventilators because they create a movement of air in the attic. They effectively avoid overheating while directly improving the building’s living comfort and the durability of the roof covering. For more information on different products, please consult the information sheet regarding the best fans.

Roof ventilation work
Les Couvreurs Duro-Toit follow the highest standards in order to optimize building performance. Depending on the type of roof, our roofers can install whatever is required for the system to be most efficient. If necessary, they can check to make sure that the ventilators are placed at strategic locations and are equal to the needs of the building. They can also ensure that the ventilators are exposed to prevailing winds as required by manufacturers who want the roof ventilation system to work in harmony with air movements and pressure differentials.
Moreover, one must consider the efficiency of the insulation that goes hand-in-hand with the roof ventilation. These two components must be appropriate in order to have a real impact on the roofing system. Our specialized team can add or replace damaged or insufficient insulation as necessary. Check with our technical consultants for more information on the insulation and ventilation of your roof.
