Roof replacement built as a full assembly, not just new shingles
A tear-off is the one chance to correct deck, ventilation, and flashing issues before they're covered over for another roof's lifespan. We treat it that way.

What a full tear-off should actually correct
A roof replacement is the only point in a roof's life when the deck, ventilation, and flashing are all fully exposed and correctable. Re-covering an existing ventilation imbalance or a marginal deck condition with new shingles just carries the same problem forward for another 20-plus years. We use the tear-off as the opportunity to fix what's underneath, not just what's on top.
Deck inspection and repair
Every square foot of exposed deck is checked for soft spots and delamination, with damaged sections replaced before underlayment goes down.
Ventilation correction
Soffit and ridge or roof-vent balance is recalculated for the new roof, correcting any imbalance from the previous system.
Ice-and-water shield placement
Membrane coverage at eaves and valleys is sized to current code minimums and, where warranted, extended further for known ice-damming risk areas.
Flashing rebuilt, not reused
Chimney, skylight, and wall flashing is rebuilt to correct lap sequence rather than reinstalled as-is.
A replacement that skips deck and ventilation correction just resets the clock on the same problem
It's possible to install a full set of new shingles over an existing deck and ventilation system without addressing underlying issues, and the roof will look complete. But if the ventilation was imbalanced or the deck had marginal moisture damage, those conditions are now sealed beneath a brand-new roof, and the same symptoms — ice damming, premature shingle aging, deck rot — will likely reappear well before the shingles reach the end of their expected service life.
Every replacement includes a full deck and ventilation correction
Deck condition and ventilation balance are assessed and corrected as a standard part of every replacement we carry out, not an optional upgrade. This adds a modest amount of time to the project but means the new roof isn't inheriting the previous system's underlying issues.
How a full replacement proceeds
The sequence is designed to correct what's underneath, not just install new material on top.
- 1
Pre-tear-off assessment
We review the existing roof, attic ventilation, and any known problem areas before scheduling the tear-off.
- 2
Tear-off and deck inspection
Old material is removed and the full deck is inspected, with damaged sections replaced.
- 3
Ventilation and ice-and-water shield
Soffit and exhaust ventilation is corrected, and ice-and-water membrane is placed at eaves, valleys, and penetrations.
- 4
Flashing and field installation
Flashing is rebuilt at all transitions before the new field material is installed.
- 5
Final walkthrough
We review the completed roof and ventilation with you before the project is considered closed.

Roof replacement questions
How do I know if it's time to replace rather than repair?
Age, extent of shingle wear, deck condition, and the pattern of any leaks all factor in. We'll give you a direct assessment rather than defaulting to replacement.
Will you check the deck during replacement, or just install new shingles?
Deck inspection and repair of any damaged sections is a standard part of every replacement we carry out.
How long does a full roof replacement take?
Most residential replacements are completed within one to a few days depending on roof size and complexity, though flashing and ventilation work isn't rushed to hit a timeline.
Will my new roof address the ice damming I've had in past winters?
We assess ventilation balance and ice-and-water shield coverage specifically to address prior ice-damming issues as part of the replacement scope.
Do you replace roofs outside Milton?
Yes, we carry out roof replacements across the Greater Toronto Area.
