Delivering a Reliable Flat-Roof Replacement with a 2-Ply Torch-On System Before Winter Weather Set In

10630 125A Street, Surrey, BC V3V 5A4

In this case study, we fixed James’s leaking flat roof, replacing rotten plywood and completing structural repairs for a lasting, reliable solution.

Project Context

James contacted Vantage Roofing Ltd after noticing active leaks coming from the flat roof area of his Surrey home. When we inspected the problem, we found the leak had been going on long enough that the plywood underneath had become soft and rotten. To make sure the repair lasted, the job needed more than a quick patch—it required structural and roofing work in the affected section.

The Challenge

The biggest challenge was timing. This project had to be completed during the fall season, when it can be difficult to get enough dry days in a row to safely complete flat-roof work, surface prep, and a torch-on installation without weather delays.

Why The Client Chose Us?

James chose Vantage Roofing Ltd because of our skill and reputation for doing roofing work properly. He wanted the job handled correctly the first time—especially with a flat roof, where poor repairs often lead to repeat leaks.

How We Responded?

We planned the work carefully around the weather and completed the project on time and on budget. The scope of work included:

Replacing the rotten plywood

Repairing trusses as needed in the affected area

Removing and disposing of two courses of shingles

Removing two feet of vinyl siding on the dormer (to access the work area)

Thoroughly cleaning and priming the existing roof surface

Installing a 2-ply torch-on roofing system

Re-installing the vinyl siding

Installing two new courses of shingles

The Results?

James now has a new, properly sealed flat roof system that protects his family home from leaks and water damage. The repaired area is structurally sound again, and the torch-on system provides dependable protection moving forward.
