Our Approach

This high-profile office tower in North York operates 24-hours a day, so a low-odour and low-noise repair method was crucial to keep the office running as usual. Working with the client, we created a strict protocol and schedule in order to minimize disruptions as much as possible. We are happy to report that during this commercial roof replacement in North York that this business remained running as usual for the duration of the 2-Ply SBS Modified Bitumen membrane repair.

Client Goal/Purpose of Project

The client’s goal for this project was to replace the aging roof of their 24/7 operational call center without disrupting business operations. The roof needed to be replaced with minimal noise and odor, as the facility required constant activity.

The selected solution was a 2-ply SBS Modified Bitumen membrane, applied using cold adhesive, which met the need for a quieter and safer installation process while ensuring long-term roof performance.
