What breaks in each season
Winter: ice loading on the cap and flashing. Spring: freeze-thaw cracking in the crown from 67 annual cycles. Summer: UV degradation on any exposed sealant. Fall: raccoon and squirrel nesting before the cold snap.

Do you offer same-day flashing repair in Markham?
Usually — call before 9am and we'll confirm a same-day arrival window inside Markham for most standard scopes.
Do you need a permit for flashing repair 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.
What if it rains or snows on the booking day?
Roof-side work reschedules to the next dry window at no charge. Interior scopes (firebox, damper, appliance) proceed regardless.
How much does flashing repair cost in Markham?
Most Markham jobs land between $387 and $619. Complex access or heritage masonry can reach $1,006. We quote fixed price after a free on-site scope.
Is flashing repair 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.
How long does flashing repair take in Markham?
3–5 hrs is typical for a straightforward job. Bookings in dense downtown zones add 15–20 minutes for parking and staging.
