Extreme Heat and Roof Damage in Markham

While winter often gets most of the attention in Markham, extreme summer heat can be just as damaging to your roof. Prolonged exposure to UV rays, high temperatures, and humidity accelerates wear and tear on shingles, flashing, and attic ventilation systems. Scheduling timely roof repair in Markham helps protect your home from the hidden effects of heat damage.

How Heat Damages Roofs

1. Shingle Deterioration – Asphalt shingles dry out, crack, or curl under extreme sun exposure.
2. Granule Loss – Protective granules on shingles loosen, leaving surfaces vulnerable to leaks.
3. Warped Flashing – Metal flashing expands and contracts with heat, creating gaps around chimneys and skylights.
4. Attic Overheating – Poor ventilation traps hot air, raising cooling costs and weakening roofing materials.

Signs of Heat-Related Roof Damage

• Curling or missing shingles.
• Discolored patches where granules have worn off.
• Higher indoor temperatures despite air conditioning.
• Water stains on ceilings from weakened shingles or flashing.
