What a proper replacement actually involves

A roof replacement is more than new shingles. Done right, it means tearing off the old roofing to check the deck underneath, correcting any ventilation problems that shortened the last roof's life, and installing underlayment and ice-and-water shield rated for what a GTA winter throws at it.

Full tear-off, not overlay

Overlaying hides deck problems and voids most manufacturer warranties — we tear off and inspect.

Deck repair as needed

Any soft or rotted decking gets replaced before new roofing goes down, not covered up.

Ventilation correction

Poor attic ventilation is a leading cause of premature shingle failure and ice damming — we fix it during replacement, not after.

Ice-and-water shield at eaves and valleys

Extra protection where ice damming and water flow concentrate, standard on every replacement we do.

What a proper replacement actually involves
The problem

An old roof rarely fails all at once

By the time a homeowner decides it's time to replace, the roof's usually been showing signs for a while — granule loss in the gutters, curling shingle tabs, repeated small leaks. Waiting too long means water's had more chances to compromise the deck, which turns a shingle job into a shingle-plus-deck-repair job.

Our solution

We assess honestly and replace thoroughly

If your roof's at the point where repair isn't cost-effective anymore, we'll tell you, and we'll do the replacement as a full system — deck, ventilation, underlayment, shingles or membrane — so the next roof actually lasts its full expected life instead of failing early from a corner that got cut.

Roof replacement questions

How do I know it's time to replace instead of repair?

Widespread granule loss, curling or cracking shingles across most of the roof, repeated leaks in different spots, and a roof past its expected service life all point toward replacement. We give you a straight assessment, not a default push toward the bigger job.

Do you always do a full tear-off?

We recommend it in almost every case. Overlaying new shingles on old hides deck problems and generally voids manufacturer warranties. A tear-off lets us actually see and fix what's underneath.

What happens if you find deck damage once tear-off starts?

We'll show you what we found, quote the repair separately by email, and get your go-ahead before proceeding. It's priced as its own line item, not buried in the original quote.

How long does a full roof replacement take?

Depends on roof size and complexity, but most residential replacements run a few days. We give you a realistic timeline up front and plan around weather.

What roofing materials do you offer for replacement?

Asphalt shingles rated for Canadian climates, along with TPO, EPDM or modified bitumen for flat or low-slope sections.
