Shingles get all the attention, but a roof is a system — underlayment, decking, flashing, valleys, vents, starter courses, and drip edge all decide how long it lasts and how it fails. The guides here explain what each component does, how the material options compare in an Ontario climate, and which details separate a roof that lasts from one that merely looks finished on day one.
This category rewards reading before a replacement: the components that matter most are invisible once the shingles go on, so the time to ask about them is while the quote is still on the table. Tactic Roofing installs complete GAF systems to manufacturer specification — every scope we write names the materials, so you know exactly what is going onto your roof.
