We recently completed a critical slate roof repair project in Parkdale, Toronto, on a historic church with a roof over 100 years old. The building experienced severe water intrusion during continuous rainfall, prompting an emergency call to our team. With water leaking into the sanctuary and other interior spaces, immediate action was necessary to prevent major damage to the structure and its contents.

The Emergency Situation

Upon arrival, our team observed active water dripping from the ceiling into the main hall of the church. The slate roof, which had served the building faithfully for over a century, was showing signs of deterioration—broken and slipped tiles, exposed underlayment, and aged flashing were allowing water to penetrate directly into the building.

Due to the historical nature of the structure, a full roof replacement was not feasible at the time. The priority was to stabilize the situation with targeted, non-invasive repairs that would protect the interior and maintain the original aesthetic and architectural value of the roof.

Targeted Repairs with Historical Sensitivity

Our experienced Toronto-based crew carefully inspected the entire roof system, identifying and prioritizing critical leak points. Repairs included:

• Replacing cracked and missing slate tiles using matching reclaimed slate

• Resealing and reinforcing damaged flashing areas, especially around intersections and penetrations

• Applying breathable sealants to vulnerable seams while ensuring water could still properly drain off the roof

Accessing the high, steep roof required specialized safety gear and scaffolding to work efficiently without damaging surrounding areas. We worked swiftly and efficiently, ensuring water ingress was stopped before further interior damage occurred.

Results: Leak-Free and Preserved

Thanks to precise repair techniques and rapid response, the Parkdale church roof is now leak-free, and the structure is protected from future rainfall. The client was extremely grateful for the professionalism, care, and respect shown to the building’s historical character.
