How Weather in Markham Impacts Your Roof

Markham’s weather is known for its variety, and while the changing seasons bring beauty, they also put constant stress on your roof. From heavy snowfall to humid summers and intense storms, local weather conditions significantly affect how long your roofing system lasts. Homeowners who understand these impacts can take proactive steps to prevent costly repairs.

Winter: Snow, Ice, and Freeze-Thaw Cycles

Markham winters bring heavy snowfall and frequent freeze-thaw cycles. Snow accumulation adds weight to your roof, particularly flat roofing systems where drainage is limited. As temperatures rise and fall, melting snow seeps into cracks, only to freeze and expand again. This process weakens shingles, flashing, and membranes.

Ice dams are another concern, forming along roof edges when melting snow refreezes. These block drainage and force water back under shingles. Preventing ice dams requires proper insulation, ventilation, and timely maintenance. When damage occurs, homeowners often need immediate emergency roof repair in Markham to stop leaks before they spread.

Spring: Heavy Rains and Storms

Spring in Markham often brings heavy rainfall and windstorms. These conditions expose weak points in your roofing system. Missing shingles, clogged gutters, and poorly sealed flashing are especially vulnerable during spring downpours. Regular inspections after storms help catch issues early. Professional eavestrough repair in Markham is also critical, as functional gutters keep water flowing away from your roof and foundation.

Summer: Heat and UV Exposure

While summer may seem like a break from harsh conditions, prolonged heat and UV rays can cause shingles to curl, dry out, and lose protective granules. Flat roofing membranes may blister or crack under high temperatures. Homeowners should look for signs of heat-related wear and schedule maintenance before small problems turn into major repairs.

Fall: Leaves and Moisture

Autumn brings falling leaves, which often clog gutters and drains. When water can’t flow freely, it pools on rooftops and seeps into vulnerable areas. For homes with skylights or chimneys, this is a high-risk period. Ensuring proper sealing and prompt chimney roof repair in Markham protects these common weak spots from moisture intrusion.

Year-Round Protection

No matter the season, regular inspections and preventative care are essential. Clearing debris, keeping gutters clean, and checking flashing reduce the risk of weather-related damage. Scheduling professional inspections twice a year—ideally in spring and fall—ensures your roof is ready to withstand Markham’s climate.
