Service: Parapet Wall Repair, Modified Bitumen Roofing, and Metal Flashing Installation
Location: Toronto, Ontario
Challenge
A property in Toronto, Ontario, required repairs to its existing parapet wall and surrounding flat roof areas. Parapet walls are important structural features that extend above the roofline and help protect the building’s roofing system from exposure to the elements.
When parapet walls and their associated roofing components require repair, they can create vulnerable areas where water may penetrate the building envelope. Proper reconstruction, waterproofing and flashing installation are essential to maintaining the integrity of the roof and reducing the risk of moisture-related damage.
Solution
Dominion Roofing completed a parapet wall reconstruction and waterproofing project to restore the affected roof areas and provide long-term protection against the elements.
Parapet Wall Reconstruction
- Removed the existing brickwork in the affected area to allow access to the parapet structure.
- Rebuilt the wood parapet to provide a suitable foundation for the new roofing and flashing materials.
- Prepared the reconstructed parapet for the installation of the waterproofing system and metal flashing.
Modified Bitumen Waterproofing Installation
- Installed a two-ply modified bitumen (mod bit) roofing system to provide waterproofing protection around the repaired parapet area.
- Incorporated the roofing membrane into the parapet repair to help protect vulnerable roof transitions against water infiltration.
New Metal Parapet and Wall Flashing
- Installed new metal parapet and wall flashing to protect the reconstructed wall and adjoining roofing components.
- Ensured the flashing was properly positioned to help direct water away from vulnerable joints and roof transitions.
- Completed the installation to support the durability and weather resistance of the repaired roofing system.
Site Cleanup
Following the repairs, Dominion Roofing cleaned the flat roof and removed all work-related debris, leaving the area clean and free of construction materials.
Result
The completed project restored the affected parapet wall and improved waterproofing protection through the installation of a two-ply modified bitumen roofing system and new metal flashing.
The reconstructed wood parapet provides a renewed foundation for the roofing components, while the modified bitumen membrane and metal flashing work together to help prevent water infiltration at critical roof transitions.
This project demonstrates Dominion Roofing’s experience with parapet wall reconstruction, flat roof waterproofing and metal flashing installation in Toronto, providing property owners with practical roofing solutions designed to protect their buildings from the elements.
