Built for Ontario Winters

A roof is only as good as what goes under the shingles. We install premium, CSA-rated architectural shingles chosen for their performance through Ontario’s freeze-thaw cycles — the repeated freezing and thawing that cracks cheaper materials and lifts seams over a few winters.

Under them, we lay a full ice & water shield in the valleys and along the eaves — the zones where ice dams form — plus a synthetic underlayment and proper drip edge. It’s the difference between a roof that looks new for a season and one that stays watertight for decades.

We’ll walk you through the exact products and colour options in your written quote, so you know precisely what’s going on your home.

Ice & water shield

Applied in valleys and along eaves to stop ice-dam water forcing its way back under the shingles.

Full deck inspection

Once the old roof is off, we check the decking and replace any rotten sheathing before the new roof goes down.

Proper ventilation

Balanced intake and exhaust ventilation keeps your attic dry, prevents ice dams, and extends the life of the roof.

What Replacement Day Looks Like

No mystery, no mess left behind. Here’s exactly how it goes.

1

Free Assessment & Quote

We measure your roof, inspect the decking and ventilation, and hand you a detailed written quote. The price you approve is the price you pay.

2

Tear-Off & Install

On the day, we place the dumpster carefully, protect your landscaping and siding, tear off the old roof, replace any bad decking, and install your new system — most homes in a single day.

3

Clean-Up & Warranty

We finish with a full magnetic nail sweep of your yard and driveway, do a final walk-through with you, and hand over your signed 10-year workmanship warranty.

Roof Replacement Questions

Still have questions?

Call and we’ll walk you through it — no pressure, no sales pitch.

The cost depends on your roof’s size, pitch, materials, and how many old layers need removing. We give you a free, no-obligation written quote with a full line-item breakdown — no hidden fees, and the price you approve is the price you pay.

Most standard residential roofs are completed in a single day. Larger homes or complex roof lines (multiple dormers, steep pitches, skylights) may take two. We give you a realistic timeline before we start.

We take mess seriously. We place the dumpster to protect your driveway, cover landscaping and siding, and finish with a magnetic nail sweep of the yard and driveway. Most homeowners are surprised how clean the site is left.

Every replacement includes a written 10-year workmanship warranty on our labour, plus the manufacturer’s product warranty on the shingles. Both are transferable to the next owner if you sell your home.

No — most homeowners go about their day. We confirm access beforehand, document the work with photos, and do a final walk-through with you when it’s done.

Yes. We help document storm or hail damage, prepare the scope of work, and communicate with your adjuster to make the claims process as smooth as possible.
