    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

    Not Enough Air = Rotten Wood

    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.

    Preventive Roof Maintenance

    Enjoy Winter Rather Than Suffering Through It

    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.

    Support Base

    Support Base for Air Conditioners, Patios, Etc.

    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.

    Roofing and the Environment

    The photograph below 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 Wiring 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.

    Gravel Membrane

    Gravel Membrane: Is it Any Good?

    Above a gravel membrane that we installed in 2001. In 2012, the neighbours’ wall fell on the membrane. The roof joists broke under the impact, but the membrane was still in one piece, with no leaks. WOW!
