Should I repair or replace my roof?

It depends on the age and condition of your roof. Isolated issues — a few missing shingles, a single leak, or damaged flashing — can usually be repaired. Widespread shingle loss, recurring leaks, sagging, or a roof near the end of its service life often make a full replacement the more cost-effective choice. We confirm the right option with an on-site inspection.

How long does a roof replacement take?

Most residential roof replacements are completed in one to three days, depending on roof size, weather, decking condition, and material availability. We confirm the schedule after inspection and keep the property protected throughout.

What roofing materials do you use for a replacement?

We install certified GAF or DECRA roofing systems, covering both asphalt shingle and metal roofing. As a GAF factory-certified contractor, we install qualifying GAF components — ice and water leak barrier, synthetic underlayment, starter shingles, and ridge cap shingles — as part of a complete system.

Repair or Replace?

Knowing When It's Time for a New Roof

Not every roofing problem calls for a full replacement. Isolated issues — a handful of missing shingles, a single leak, or damaged flashing — can usually be handled with a targeted roof repair. A replacement becomes the smarter investment when the damage is widespread or the roof is simply reaching the end of its service life.

Common signs that point toward replacement include recurring or multiple leaks, large areas of curling, cracked, or missing shingles, granules collecting in your gutters, daylight visible through the roof deck, and a sagging roofline. If your roof is showing several of these at once, repairs can become a series of short-term fixes rather than a lasting solution. Our guide on 10 signs you need a roof repair or replacement walks through what to watch for, and roof restoration vs. roof replacement explains how to weigh your options.

Putting it off rarely makes the problem cheaper to solve — water that gets past the shingles can damage decking, insulation, and interior finishes. We cover that trade-off in the hidden costs of delaying a roof replacement. The most reliable way to know where you stand is a professional inspection, which we provide as part of every free quote.

How It Works

Our Roof Replacement Process

A clear, methodical process — from first inspection to final cleanup — so you always know what's happening on your roof.

Inspection & Assessment

We start with a thorough roof inspection to check the shingles, flashing, decking, and ventilation, then confirm whether a repair or a full replacement is the right call.

Materials & Estimate

We review your material options — certified GAF or DECRA shingle and metal systems — and provide a free, no-obligation written estimate before any work begins.

Tear-Off

Our crew removes the old roofing down to the deck, inspects the exposed decking, and addresses any damaged plywood or OSB before the new system goes on.

Installation

We install the new roofing system to GAF guidelines — ice and water leak barrier, synthetic underlayment, starter shingles, field shingles, and ridge cap.

Cleanup & Final Check

We clear debris, run a magnet sweep for stray nails, and complete a final inspection so your property is left clean and your new roof is ready for Ontario weather.
