Location: North York, Ontario
Challenge
A property in North York required specialized flat roof repair work to address a failing drain assembly and aging roofing materials. The existing cap sheet needed to be removed so the drainage area could be properly accessed and updated.
Because flat roof drains play an important role in moving water off the roof, it was essential to replace the drain with a secure and reliable new component. The surrounding roofing system also needed to be rebuilt with new modified base and cap sheet materials to restore waterproofing and long-term performance.
Solution
Dominion Roofing completed the repair by removing the existing cap sheet, replacing the roof drain, and installing a new 2-ply modified roofing system around the repaired area.
Removal of Existing Cap Sheet
- Removed the existing cap sheet from the affected flat roof area.
- Opened up the roofing system to access the drain and surrounding materials.
- Prepared the section for proper replacement and rebuilding.
Drain Replacement
- Replaced the existing roof drain as part of the repair.
- Installed a new 2 ¾” copper drain with U-flow.
- Updated the drainage point to improve water movement and long-term reliability.
Installation of New 2-Ply Roofing System
- Installed a new modified base sheet in the repaired area.
- Added a new cap sheet to complete the 2-ply modified roofing system.
- Restored the flat roof surface with durable materials designed for improved waterproofing and protection.
Result
The completed roof repair in North York replaced the failing drain assembly and rebuilt the surrounding flat roof area with a new 2-ply modified base and cap sheet system. With the installation of a new copper drain and updated roofing materials, the property now benefits from improved drainage and a stronger, more reliable waterproofing system.
