The Markham scheduling window
We aim to complete pre-winter shingle replacement on Markham homes by the last Saturday in October. Book by Labour Day for that window — after that we're scheduling against weather.

Late September through mid-November is the sweet spot: Markham averages 148cm of snow starting in December, so roof access closes fast. Spring bookings (April–May) are second-best and often 10–15% cheaper.
