Six Warning Signs Your Toronto Roof Needs Immediate Repair

1. Moisture Intrusion

Dampness in attic or ceiling stains indicates active leaks. Moisture rots decking, breeds mold, and compromises insulation. Early repair prevents structural escalation.

2. Curled or Cupped Shingles

Wind-vulnerable and ventilation-impeding, curled shingles signal aging or attic heat buildup. They shed granules faster, accelerating failure.

3. Rotted Decking or Sheathing

Brownish-red discoloration on roof planes reveals advanced rot. This structural compromise requires immediate professional assessment—often mandating section replacement.

4. Granule Loss

Bare shingle spots or granules in gutters mean UV protection is gone. Accelerated cracking and leaking follow. Post-storm inspections are critical.

5. Damaged or Missing Flashing

Dented, loose, or absent flashing at chimneys, valleys, and walls allows water entry. Often repairable without full re-roofing if caught early.

6. Skylight Failures

Cracked glazing, failed seals, or improper installation turn skylights into leak funnels. Professional inspection determines repair vs. replacement.
