Roof Repairs in North York (Residential)

Service: Roof Repair

Location: North York

Challenge

The homeowner needed a targeted roof vent repair on their asphalt-shingle roof in North York. Our service technicians found that the existing sealant around the two bathroom exhaust vents had cracked and deteriorated over time. This breakdown can let moisture slip beneath surrounding shingles, increasing the risk of small leaks, hidden wood rot, and interior water damage if left untreated.

Solution

The team from Dominion Roofing completed a series of targeted repairs to restore a watertight seal around the roof’s bathroom vent penetrations and reduce the risk of moisture intrusion:

Sealant Removal & Surface Prep

• Removed old, loose, and deteriorated sealant around both bathroom exhaust vents
  
• Prepared the surrounding areas to ensure proper adhesion and a clean finish
  

Vent Re-Caulking & Waterproofing

• Re-caulked two bathroom exhaust roof vents using roofing-grade sealant
  
• Applied a continuous bead of sealant around:
  
  • Vent caps
    
  • Perimeter flanges
    
  • Any exposed nails and fasteners
    

Type of Repairs

• Roof vent re-caulking (bathroom exhaust vents)
  
• Sealant removal and replacement at roof penetrations
  
• Waterproofing reinforcement at vent flanges and exposed fasteners
  

Worksite Safety & Cleanup

• Ensured safe access for all workers throughout the repair process
  
• Cleaned all work-related debris, leaving the property clear and orderly

Result

Both bathroom exhaust vents were properly resealed with fresh roofing-grade caulking, restoring a clean, watertight finish at the roof penetrations. The roof is now better protected against wind-driven rain and moisture entry – helping prevent minor sealant failures from turning into costly leak repairs.
