Roofing Contractors in Newmarket

Yes, for a full replacement that strips to the deck. The Town of Newmarket requires a building permit for complete roof replacements, submitted through Town Building Services. Confirm with Town staff whether re-shingling over existing layers requires a permit for your specific project. For properties near the Holland River or its tributaries, an LSRCA permit may also apply for associated grading or drainage work.

Verify WSIB clearance, a minimum $2M general liability policy, and that they will pull the Town of Newmarket building permit. Ask for proof of manufacturer certification if you want a full system warranty (e.g. GAF Certified, IKO Shield Pro). Workers must carry Ontario OHSA-compliant fall-arrest training certificates. For properties near the Holland River or other LSRCA-regulated watercourses, confirm the contractor's familiarity with LSRCA permit requirements.

Newmarket's location at the south end of the Lake Simcoe watershed means it receives lake-effect snow influence from Lake Simcoe during northwest wind events, and the freeze-thaw cycle is active through late winter and early spring. Ice damming is a significant risk on older Main Street and central Newmarket homes with inadequate attic ventilation - ice-and-water shield installed from the eave to at least 900mm inside the heated wall is the minimum standard throughout Newmarket. Northern neighbourhoods including Stonehaven face greater wind exposure and heavier snow loading, making proper ridge cap, hip, and flashing installation especially important.

Properties within or adjacent to the Holland River and its tributaries may be in an LSRCA regulated area, where significant grading or drainage work associated with a roofing project could require an LSRCA permit before the Town of Newmarket building permit can be issued. Confirm regulated area status at the pre-quote stage by contacting the LSRCA or asking your contractor to check the LSRCA online mapping tool before finalizing scope.
