Storm Damage Guide: Shingle Replacement After Severe Weather in Markham
Here's how Markham homeowners actually approach shingle replacement in 2026, based on what our field crews see every week. Deeper freeze depths mean liner condensation and cap ice-loading. Below: what to expect, real numbers, and the questions worth asking before you book.
Quick answer
The three signs Markham homeowners keep missing on shingle replacement: smell changes, staining above the firebox, and unusual sound. Any one means schedule; two together means stop-use.
Typical
$12–$19
Duration
1–3 days
Freeze-thaw
67/yr
Signs the shingle replacement can't wait
The most reliable early warnings on Markham homes: smell changes near the appliance, staining above the firebox or on interior ceilings, unusual soot at the cap, and any water inside the smoke chamber. Any one of these is a call — two together is a stop-use.
The 90-second self-check
Look at the cap for gap or crushing, walk the crown for hairline cracks (67 freeze-thaw days a year here will find any weakness), and shine a light up the flue for glazing. Photograph anything unclear and text it over.
When to stop using the appliance
Any active water ingress, visible flame licking outside the firebox opening, or the smell of gas products in the room means shut down and call. Insurance coverage on damage during "known unsafe operation" is thin.
Common questions
What warranty do you offer on shingle replacement in Markham?
Five-year written workmanship warranty on materials and labour, transferable to a new homeowner within that window. Manufacturer warranties on any installed products pass through separately.
Do you service condos and heritage homes in Markham?
Yes. Condo boards in Markham typically want a scope letter and insurance certificate 48 hours out; heritage properties need product substitutions we pre-source.
How much does shingle replacement cost in Markham?
Most Markham jobs land between $12 and $19. Complex access or heritage masonry can reach $31. We quote fixed price after a free on-site scope.
Do you need a permit for shingle replacement in Markham?
Cleaning and inspection are permit-exempt in Markham. Structural masonry, liner replacement, or a new appliance install typically need one — we pull it as part of the job when required.
Do you offer same-day shingle replacement in Markham?
Usually — call before 9am and we'll confirm a same-day arrival window inside Markham for most standard scopes.
When's the best time of year for shingle replacement in Markham?
Late September through mid-November with Markham averaging 148cm of snow starting December. Spring (April–May) is the second window and often 10–15% cheaper.
How long does shingle replacement take in Markham?
1–3 days is typical for a straightforward job. Bookings in dense downtown zones add 15–20 minutes for parking and staging.
Is shingle replacement covered by home insurance in Markham?
Sudden damage (storm, animal, appliance failure) is usually covered minus deductible. Gradual wear generally isn't. A written pro assessment before the claim call materially improves outcomes.
