Markham’s climate is a unique mix of hot summers, cold winters, and frequent storms. These weather patterns take a toll on roofing materials and can shorten the lifespan of your roof if not addressed with proper maintenance. Knowing how local weather impacts roof durability helps homeowners plan timely roof repair in Markham and extend the life of their roofing system.
Weather Challenges in Markham
- Heavy Snow and Ice
Snow buildup and ice dams strain roofing structures. Over time, this leads to leaks, sagging, and the need for professional eavestrough repair in Markham to maintain proper drainage. - Freezing Temperatures
The freeze-thaw cycle expands cracks in shingles, flashing, and mortar. This weakens the roof and increases the risk of water intrusion. - Intense Summer Heat
Direct sunlight and high temperatures dry out shingles, causing them to curl, crack, and lose granules. Poor attic ventilation makes this worse. - Storms and High Winds
Severe storms often rip off shingles, loosen flashing, and create conditions requiring emergency roof repair in Markham.
How Weather Impacts Different Roofing Materials
- Asphalt Shingles: Most common in Markham, lasting 15–25 years, but prone to curling under heat and cracking in cold.
- Flat Roofs (EPDM, Modified Bitumen): Typically last 20–30 years, but require regular inspections for pooling water.
- Metal Roofs: More durable, but seams and fasteners can loosen in extreme temperature swings.
Extending Roof Life Expectancy
- Schedule seasonal inspections with a trusted roofing company in Markham.
- Keep gutters clear to prevent water from backing up under shingles.
- Reinforce flashing around chimneys, skylights, and vents.
- Ensure attic insulation and ventilation are functioning properly.
Warning Signs of Weather Damage
- Missing or damaged shingles.
- Water stains on ceilings or attic insulation.
- Mold or mildew growth in damp areas.
- Sagging gutters or pooling water near the foundation.
