Looking down from an airplane, you can see that many buildings in the City of Montreal have flat or very low slopes roofs. Why is this? At Couvreurs-DM, we specialize in flat roofs everywhere from Lasalle to St-Leonard, from Old Montreal to Ville St-Laurent and elsewhere in Montreal and the West Island. In this article, we reveal how something that seems so normal to Montrealers is actually a big part of the city’s history. Once you read this, you’ll probably never see roofs the same way again!
