Lundy’s Lane – Commercial Retail Plaza Retrofit (Niagara Falls, ON) | Final Roofing Solutions

Project Background

This multi-tenant retail plaza on Lundy’s Lane was experiencing recurring leaks and heat-related membrane degradation across the existing 4-ply Built-Up Roof. A full tear-off would have disrupted active businesses and created unnecessary landfill waste. The property ownership group prioritized a solution that would improve performance and tenant protection while remaining cost-efficient and time-conscious.

Our Solution

Final Roofing completed a roof recovery system using the Johns Manville 2-Ply SBS Modified Bitumen System. This approach allowed the existing roof assembly to remain in place while providing a new high-performance waterproofing membrane.

Key steps included:

• Moisture scan and targeted wet section cut-outs

• Surface prep + primer for optimal adhesion

• Base sheet installation across the full roof field

• Cap sheet installation with heat-welded laps for long-term durability

• Reinforcement detailing at drains, walls, HVAC curbs, and penetrations

Results

• Extended roof service life without a full rip-out

• Minimized tenant disturbance and business downtime

• Enhanced resistance to ponding, UV, and seasonal weather changes

• Reduced environmental impact by avoiding unnecessary disposal

This roof is now protected under the Johns Manville system warranty, along with our own workmanship guarantee.
