22 Years on Calgary's Toughest Roofs

J Cubed Custom built its name in commercial flat roofing — specializing in SBS and two-ply torch-on membrane systems, the leak-critical applications that don't forgive shortcuts. We've worked in that sector for 22 years, on projects ranging from multi-level and tower construction down to residential flat sections and full home roofs.

That range is the whole point: a crew trusted to waterproof a tower can more than protect your home. Today J Cubed Custom is a full-service roofing company across both flat and sloped applications, and our work can be found throughout Calgary and the surrounding region.

We also carry extensive framing knowledge and understand how a structure is built — which is essential to how its waterproofing performs. On renovation projects we routinely find that building practices from 20–30+ years ago were approached very differently; the knowledge we carry today is what lets us prevent the costly, unforeseen issues that catch other roofers out.
