The Types of Commercial Roofs We Install
TPO Roofs
TPO stands for thermoplastic polyolefin. TPO roofing is a single-ply membrane made of rubber that covers the surface of your roof. It is a very durable and cost-effective option for commercial roofs, potentially lasting up to 30 years if properly cared for.
PVC Roofs
PVC roofs are made from polyvinyl chloride. Like TPO roofs, it is also a single-ply membrane that covers your roof. It is a strong and stable material that can be installed by welding rather than adhesive.
Flat Roofs
Flat roofs are a great option for businesses because they require fewer damage and repair costs over the lifespan of the roof. We specialize in flat roofs for commercial and industrial buildings and are happy to answer any questions you may have throughout the entire replacement and installation process.
