Waterproof Breathable Membrane

Sometimes, the most important part of a roof can be what’s directly underneath it. That statement doesn’t refer to the attic or crawlspace of a building, but rather the waterproofing membrane that goes beneath the steel roofing. Metal roofers choose their construction membranes very carefully, making sure to apply the material that can best protect a home. Roofing contractors in Toronto need to use a waterproof breathable membrane to obtain the best results.

The Quality You Expect
ZIM Group certainly blew us away with the job they did on our roof recently. The whole job was so professional from start to finish and we cannot recommend them highly enough to anybody else who needs a metal roof built for them.
