Fast 5-Day Replacement with R-25 Insulation

The Roof Condition

This Welland warehouse had been running on 1″ polyiso and 0.5″ fiberboard for years. That gave it an R-value of about R-4, which is barely functional through an Ontario winter. The membrane was deteriorating, energy costs were climbing, and the owner needed a full replacement without shutting down operations.

The Replacement Process

We craned all materials onto the roof on day one to keep the ground level clear and the building entrance accessible. From there, the crew worked through four stages: tear-off of the old system, installation of 4″ polyiso with 0.5″ fiberboard to bring insulation up to R-25, hot-mopped base sheet application, and a torch-applied cap sheet to finish the two-ply modified bitumen system.

The Videl Difference

When commercial roof replacements drag on for weeks, these delays turn into tenant complaints, blocked entrances, and unexpected cost overruns.

At Videl Roofing, we got the job done in five working days. The building stayed fully operational from start to finish, the parking lot was clear by the end of each shift, and the owner now has a brand new flat roof system built to handle Ontario winters for decades to come.
