Borough of Ville-Marie

This borough is the only one in Montreal, and no doubt in Quebec, to require a certified engineering plan for traffic if our trucks take up more than 3 metres in the street, which is common. Consequently, in many cases, owners in this borough cannot have the work done within a short time frame, due to the procedures to be followed in order to obtain the engineering plan.

Ice Dams

Ice that forms at the bottom of a sloping roof is generally caused to a ventilation or insulation problem in the attic. The problem is that a dam of ice forms at the bottom of the slope, and restricts water evacuation, which means that stagnant water remains on the shingles, which are not at all designed for that.

Rotten Wood, Carpentry, Ventilation

We often replace roofing (membranes) and see that there is rotten wood. Of course, water infiltration can cause that kind of damage, but it’s often a lack of air that damaged the (wooden) decking. In certain cases, there could be signs, especially in cold weather between December and March.

Preventive Roof Maintenance

We recommend that, in order to spend the winter in peace, without water infiltration, several items should be checked on your roofing membrane, whether it is new or old, because there is a lot more than just the membrane on your roof. Read more here.

Support Base

Some owners, and even some so-called professionals, have been very generous to us as roofers by creating a lot of work. When it comes to installing a heat pump, patio or any other item on your membrane, you should know that, ideally, NOTHING should be installed directly on the membrane. Details here.

Roofing and the Environment

The photograph above shows that when the covering was removed, there were four membranes instead of one. If there’s a subject that you hear a lot about in our field (and many others), it is the social awareness that we must have with respect to how our daily activities affect our environment, and we, like most of you, consider that to be a true and very important fact.

Electrical Tripod Bases

As with many other aspects of flat roofs, tripod bases are only very rarely inspected, and they can cause serious damage to your roofing membrane. More details here.

Dryer Vent

Class Action Involving BP Shingles

During the course of our work, we have seen problems related to the premature wearing on roofs in Montreal. Perhaps you have had this problem. If you have had shingles installed since 1985, it is important to pay particular attention to the condition of the shingles, because you could benefit from this class action.

Roof Snow Removal

When a certain quantity of snow accumulates, it must be removed from the roof. CAUTION: There are procedures that must be followed so that the roofing membrane is not damaged, because it is much more fragile in the winter. Read more.

Flat Roof Coverage: Avoid Clogged Drains

Clogged drain openings and water pipes are the most frequent problems and the most damaging for a flat roof. Whether your membrane is new or old, no matter how good it is, the risk is very high and very serious that there will be major water infiltration. Read more here.
