Last week M&R Roofing completed a flat roof balcony repair in Toronto where we installed our two ply modified bitumen flat roofing system with polyiso roof insulation and built a new balcony railing.
Our client's home featured a balcony accessible from the dormer walkout on the front slope of the house.  This house design is typical in western East York neighbourhoods.  Many of the homes have balconies that are leaking and are rotten.  The railings, decks and even rafters under the decks are rotten because the balconies are covered with subpar materials.  Since the balcony is exposed to the outdoors it should be waterproofed with some type of flat roofing system.  Specifically one that inludes some form of insulation as the balcony area is above a warm area of the house and should be insulated to prevent condensation problems.  Previously the balcony was covered with welded galvanized metal.  Metal is not a good solution for this sort of flat roof area because with time the welds will begin to crack and the metal will begin to move around.  Metal also causes condensation as the warm air from the house meets the cold metal surface.  To prevent condensation issues we installed 1.5 inch polyiso insulation.  We also disassembled the side wood walls and the door step in order to run the rubber membrane up onto the walls and under the door step.  We then flashed the area with black metal flashing and caulked it appropriately.  After installing the new flat roof we built and installed a new wood railing on the balcony.  The new railing is built according to code standards which makes it sturdy and accessible for the client.  The client can now confidently choose to install some form of decking to her liking over the flat roofing system.
