Snow guards positioned above doorways, walkways, porches, sidewalks and anywhere where falling ice or snow by Toronto roofing companies may present a hazard. They’re made of either galvanized steel, painted steel, stainless steel, copper, aluminum or bronze, and may he lead coated. Some are available as `snow tailings," an elongated version of the snow guard.
Lighting Rods
Lightning rods are common on old slate roofs. They’re often nailed onto the roof right through the slate, usually with rather large (i.e. 16 penny) nails, and the nail heads are caulked or cemented to prevent leakage. The feet of old lightning rods will sometimes cause leaks because the cement over the nails has worn away, and a fresh application of roof cement or silicon caulk will cure the problem. Lightning rods are designed to divert electric current away from a building by channeling the current through a heavy copper or aluminum cable into the ground. Therefore, a lightning rod must be properly grounded or it won’t work at all.
