    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.

    Rotten Wood, Carpentry, Ventilation

    Not Enough Air = Rotten Wood

    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 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.
