What happens when a commercial roof is replaced?

A commercial roof replacement starts well before the first crew climbs onto the roof. The process begins with an inspection and core analysis. Next comes professional measuring, along with a budget that fits your funding source. From there, our team recommends roofing systems and materials that suit your building and your goals. Before tear-off begins, we can advise on asbestos testing and make recommendations on decking replacement. We also plan interior protection and set a schedule that keeps disruptions to your operations as low as possible.

Which roofing systems suit flat commercial buildings?

A commercial flat roof replacement usually centers on the membrane. Common options include TPO, EPDM, PVC/KEE, modified bitumen and built-up roofing. The first few are single-ply membranes, while modified bitumen and built-up systems are multi-ply. Roof conditions decide the scope of the work. Some projects call for a full tear-off down to the deck. Others are good candidates for an overlay or retrofit over the existing system.

Is a full roof replacement always necessary?

Some aging roofs can stay in place for a while longer. If an inspection shows a lesser need, a repair or renewal can extend the life of the current system until a re-roof makes sense. When the damage runs deeper or the system has reached the end of its service life, a commercial new roof is often the more practical path.

Frequently Asked Questions About Roof Replacement

A commercial roof replacement follows a clear process: inspection, measuring and budgeting, system selection, pre-construction planning, and finally tear-off and installation. Much of the most important work happens before a crew ever steps onto your roof.
Roof inspection and core analysis. We inspect your existing roof and take core samples to see what’s underneath, including how many layers are present and the condition of the insulation and deck.
Measuring and budgeting. Our team takes precise measurements and builds a budget that works with your funding source, whether that’s capital reserves, insurance, or a phased plan.
Choosing the right roofing system. We recommend commercial roofing systems and materials suited to your building, climate, and long-term goals.
Pre-tear-off planning. Before removal begins, we advise on asbestos testing and roof deck replacement, plan interior protection, and set a schedule that keeps disruption to your business as low as possible.

The best roofing system for a flat commercial building depends on your roof’s condition, how the building is used, and your budget. Most flat roof replacements center on the membrane, and the most common options fall into two groups: single-ply and multi-ply systems.
Single-ply membranes
TPO: A white, reflective membrane with heat-welded seams, popular for its energy efficiency and cost-effectiveness.
EPDM: A synthetic rubber membrane with a long track record of durability and flexibility in changing temperatures.
PVC/KEE: A heat-welded membrane that resists chemicals, grease, and fire, making it a strong fit for restaurants and industrial facilities.
Multi-ply systems
Modified bitumen: Asphalt-based sheets reinforced for strength, installed in layers for added puncture resistance.
Built-up roofing (BUR): Alternating layers of bitumen and reinforcing felts, often topped with gravel, for a thick, redundant barrier.

Your roof’s current condition determines the scope of the project. If the existing roof is wet, deteriorated, or already has two layers, a full tear-off down to the deck is usually required. If it’s dry and structurally sound, a roof overlay or retrofit over the existing system can save time and money while extending the roof’s life.
