Roofing systems
Commercial roofing systems
A quick guide to the systems we work with, where they are often used, and what affects whether one is right for your building.
TPO
A single-ply membrane, often white, that is heat-welded at the seams. It is a common choice for low-slope commercial roofs.
Often used on
- Warehouses
- Retail centers
- Office buildings
What affects suitability
- Condition of the existing deck and insulation
- Amount of rooftop equipment and foot traffic
- Attachment method required for the building
All systems at a glance
| System | Overview | Often used on |
|---|---|---|
| TPO | A single-ply membrane, often white, that is heat-welded at the seams. It is a common choice for low-slope commercial roofs. | Warehouses, Retail centers, Office buildings |
| EPDM | A synthetic rubber membrane installed in large sheets. It is flexible and has a long track record on flat roofs. | Low-slope buildings, Additions, Roofs with fewer penetrations |
| Modified Bitumen | Asphalt-based rolls with reinforcement, installed in layers. It is often torch-applied or self-adhered and is known for its toughness. | Retail and shopping centers, Roofs with regular foot traffic, Multi-layer systems |
| Metal | Standing seam and panel systems for sloped commercial roofs. Metal can also be restored with coatings in some cases. | Warehouses and industrial buildings, Sloped commercial roofs, Covered walkways |
| Roof Coatings | Liquid-applied coatings that cover an existing roof surface. They can extend the useful life of a roof that is still structurally sound. | Aging but sound membranes, Metal roofs, Buildings that want to avoid a full tear-off |
Lifespan and performance depend on the building, installation, and maintenance. We will explain what to expect for your roof after an inspection.
