Oh no! The roof of my building is leaking, can you help me?
Mascotte Duro Toit
Don't panic! We'll send a team to the rescue right away! Leaks are often the result of a weakness in a roof's waterproofing, either generally or in one particular place. Damaged accessories, blocked drains, or deteriorating metal flashings can also cause water infiltration.
Water Infiltration
Mascotte Duro Toit
To quickly determine whether or not your roof is being damaged by water infiltration, let me check to see if there are stains on the ceiling, if paint is peeling, if there are weak or cracked sections of the roof, or bubbles on the roof covering. This will help me to pinpoint the source of the problem and then draw up a plan of action!
Roof Inspection

As you can see by looking at your roof, an inadequate slope does not allow water to run off properly, allowing puddles to form. These accumulations of water may be problematic if they do not disappear within 72 hours.

Warning! When working on a flat roof, we introduce special security measures, such as installing guardrails, establishing a security perimeter, and more.
Work Safety

Since water infiltration can damage your roof's decking or insulation, it may be necessary to replace them in whole or in part. In that way, our staff and I will be able to ensure the maximum performance of the roof.
Roof Structure and Decking

Before making changes to the insulation, we have to determine the type of system in place to best meet the needs of the building.
A number of variables must be considered when it comes to choosing insulation, such as tolerance to compression and the R-Value. Polystyrene foam and polyisocyanurate are, for this purpose, among the most common products for thermal roofing systems. For ventilated roofs, sprayed urethane, fibreglass, and cellulose are among the most recommended types of insulation.
Once the insulation phase is completed, we can install joists in the opposite direction. In addition to heightening the roof, this structural change allows maximum air circulation in the attic, among other benefits. This process also allows us to correct the slope!
Roof Insulation

A gap of air will thus be created between the roof and the new insulation to promote air circulation. Heat transfers will thereby be expelled and the formation of ice greatly diminished. This will automatically result in a reduced risk of water infiltration and a subsequent weakening of the structure due to excessive weight!
Roof Structure and Decking

To create the best system, you need to optimize the number and the strategic positioning of fans; adding or changing them can be a practical and cost-effective solution, as well as making your work more durable.
Roof Ventilation

The installation of vapour barriers and firewalls is essential to ensure optimal performance of your flat roof, because the membrane serves as a screen that protects against moisture and fire.
Roof Waterproofing System
Mascotte Duro Toit
My team and I must install support panels made of fire retardant wood fibre. These are specially designed to offer a surface without imperfections onto which the membrane can be applied. Being fireproof, these panels also prevent the spread of fire!
Roof Waterproofing System

To complete the covering, two layers of elastomeric membrane that make the roof waterproof are fused together. Psst! Choosing a white topcoat, rather than black, will help to reflect UV rays and thus combat the formation of heat islands on the roof!

The roof curbs will be coated with a primer and then covered with two membrane layers, plus a sheet of steel, leaving no area at risk.

As membranes are subject to many standards and requirements, doing business with a professional, like me, is essential! You will be assured of having a quality membrane, which will be durable, compliant, and tailored to meet the needs of your building.

Even with a quality roofing system, snow accumulation is inevitable in winter. Prevention is the only way to counter the damage that snow accumulations could cause. However, snow removal involves risks, which is why dealing with professionals, like my team and me, is highly recommended!
We install guardrails and manage disposal areas, in addition to prohibiting access to areas at risk and paying attention to different roof elements, so as to not damage the components.
