Windsor-Essex Commercial Roofing Contractor

A commercial roof failure doesn’t just cost money — it disrupts operations, exposes inventory, and puts occupants at risk. Cléroux & Sons Roofing has been installing and maintaining commercial roofing systems across Windsor and Essex County since 1995, and we understand what’s at stake when a low-slope or flat roof starts to fail.

We work with property managers, business owners, contractors, and building operators to assess, specify, and install the right roofing system for each structure. Whether you’re managing a retail strip, an industrial facility, a multi-unit residential building, or a warehouse, we bring the same precision and accountability to commercial projects that Windsor homeowners have relied on for three decades.

Understand Your Roof's Condition Before Committing to Anything

Commercial roofing decisions involve real capital expenditure and building performance risk. Before recommending any system or scope of work, Cléroux & Sons conducts a thorough on-site assessment of your existing roof — examining the membrane, insulation layers, drainage configuration, flashing, penetrations, and deck condition.

You’ll receive a straight answer about what your roof actually needs: whether that’s a targeted repair, a re-cover, or a full replacement. We don’t pad commercial scopes to increase job value. Our goal is an accurate picture of your building’s condition and a realistic recommendation you can plan against.

Answers for Property Owners & Managers

Commercial Roofing Questions, Answered

What types of commercial roofing systems do you install?

We install TPO membrane, EPDM rubber roofing, modified bitumen (torch-applied and self-adhering), and built-up roofing (BUR) systems. The right system depends on your building’s structure, drainage configuration, insulation requirements, and budget. We’ll recommend what’s appropriate for your specific property — not simply what we prefer to install.

In many cases, yes. If the existing membrane is in sound condition and damage is localized, targeted repairs can address the problem without replacing the full system. Where a single existing roof layer is present and the insulation beneath is dry and intact, a re-cover — installing a new membrane directly over the existing one — can extend service life significantly without the cost or disruption of a full tear-off. If the building already has two roofing layers, re-cover is not an option under Ontario Building Code and a full replacement is required. Our assessment process determines which approach is appropriate based on the actual condition of your roof.

It depends on roof size, system type, deck condition, and site access — and the honest answer is the range is wide. A straightforward single-ply installation on a smaller commercial building may be wrapped up in two to three days. Larger roofs, complex geometry, multiple penetrations, or deck repairs discovered after tear-off can extend a project to one to two weeks. We provide a confirmed schedule at the assessment stage and communicate immediately if conditions on-site change the timeline.

Yes. Most commercial roofing projects are completed on occupied buildings, and we plan accordingly. We manage material staging, noise, access points, and working hours to minimize impact on tenants and business operations. For sensitive environments, we’ll discuss phasing options during the assessment.

We take on commercial roofing projects throughout Windsor-Essex, including LaSalle, Tecumseh, Amherstburg, Kingsville, Leamington, and the surrounding area. If your property is in Essex County, reach out and we’ll confirm coverage for your location.

Our assessment covers the full roof system — membrane condition and visible defects, flashing and penetration integrity, drainage performance, insulation condition where accessible, and deck stability indicators. You’ll receive a written report with findings, photos, and a prioritized set of recommended actions. Confirm with us directly whether your project qualifies for a complimentary assessment when you reach out.
