Shingle Roof
Roof replacement scoped for freeze-thaw winters, not just 'new shingles on top'
A full tear-off is the moment to get underlayment, ventilation, and flashing right — because once the new shingles are down, those details are hidden again for another twenty-plus years.

What actually goes into a proper roof replacement here
A roof replacement quote that only mentions the shingle brand is missing most of what determines whether that roof holds up through Ontario winters. Underlayment coverage, ice and water shield at eaves and valleys, ventilation balance, and flashing detail all get decided during a tear-off — and all of them matter more here than in a milder climate.
Ice and water shield coverage at eaves and valleys
Ontario building code has minimums for this, and we won't quote below them — this membrane is what keeps ice-dam backup from soaking through the decking.
Ventilation gets corrected during tear-off
A full tear-off is the easiest time to fix an intake-exhaust imbalance that's been driving ice damming or premature shingle aging — it's far more disruptive to fix later.
Flashing is replaced, not reused
Old flashing around chimneys, vents, and valleys should be replaced during a full re-roof, not caulked and reinstalled — reused flashing is a common source of early leaks on a 'new' roof.
Decking gets inspected once it's exposed
Tear-off is when we can actually see the decking condition. If sections need replacing, that gets flagged and priced before shingles go back down, not discovered as a surprise after.
A 'new shingles, same price' quote is hiding the parts that actually matter
When a replacement quote is dramatically lower than others, it's rarely a better shingle deal — it's usually minimum-code (or below) ice and water shield coverage, reused flashing, and no ventilation correction. Those cuts are invisible on install day and expensive the first hard winter after.
Our replacement quotes itemize what happens under the shingles
We specify underlayment type and coverage, ice and water shield placement, ventilation changes if needed, and flashing replacement scope in writing. You'll know exactly what's being done beneath the surface, not just which shingle colour you picked.

Roof replacement questions
How long does a full roof replacement take?
Most residential tear-offs and reshingles take one to a few days depending on roof size and complexity, weather permitting.
Will you fix ventilation as part of the replacement?
If the inspection shows an intake-exhaust imbalance, we'll include the correction in the written scope rather than leaving it for later.
Do you reuse old flashing to save cost?
No — flashing gets replaced during a full tear-off. Reused flashing is one of the more common causes of leaks on an otherwise new roof.
What happens if you find rotten decking once the shingles are off?
We'll show you the affected area, explain the repair needed, and price it before proceeding, rather than assuming and adding a surprise charge afterward.
Can you match my neighbourhood's shingle style for resale value?
Yes, we can review shingle colour and profile options that fit the neighbourhood's look if that's a priority for you.
