Commercial Roofing

Most commercial buildings are low-slope and require a single ply roofing material – that is a roofing material that essentially acts as one large roofing membrane. The most common single ply roofing membranes are TPO, PVC, and EPDM. These membranes are available in rolls and are hot-air welded to each as they are installed. As a result, a single ply roofing membranes is more resistant to slow moving water than, for example, asphalt shingles.

Being a commercial roofing company, we install, maintain, and repair the above mentioned single ply roofing products, as well as modified bitumen. These systems can be installed onto any roof, be it commercial or residential, as long as the pitch isn’t too steep.

A commercial building can have a non-single ply roofing product, such as shingles, metal, or tile, if the slope is steep enough. That said, you can install a commercial roofing product onto a residential building. We often install EPDM onto home additions and detached residential garages. Some steep slope roofs have a section that is low slope which has a low slope roofing material, such as modified bitumen. It’s not uncommon to use some amount of modified bitumen on a modern home’s roof.

New Commercial Roof

Choosing a single-ply roof for your commercial building is relatively easy. Assuming you have a low-slope roof, start by asking yourself if greases, oils, or fats are being used inside your building. If they are, PVC is the right choice as it is resistant to these. If you answered no to that question, is money a concern? If not, go with TPO since it’s less expensive than PVC yet still a great product. If money is a concern, go with EPDM since it’s the least expensive single ply roofing material. Let us know if we can help you with your new commercial roof.

Single-Ply Roofing Systems We Offer


PVC is a type of plastic. It holds-up very well to harsh weather. Most restaurants choose PVC roofs because it is resistant to animal fat and grease. The average lifespan of a PVC roof that is not re-coated is about 20 years. PVC is strong, but not as flexible as TPO or EPDM. Learn more about a new pvc roof to see if it’s right for you.


A reflective membrane made from fused polymer and rubber. If the building is not a restaurant, TPO is a good choice. A new TPO roof last about 25 years without additional coatings. TPO is less expensive than a PVC roof. It is non-toxic and is recyclable. Because it reflex UV radiation, it helps keep your Summer utility bills lower.


The ‘rubber roof’. A very durable rubber membrane most commonly used on low-slope commercial buildings, detached garages, RVs. EPDM is the least expensive of these single membranes, yet the one that lasts the longest. The average lifespan of a new EPDM roof is 30 years.

Commercial Roofing Installation

Correctly and professionally installed, high quality commercial roofing materials from reputable manufacturers is key. These are the first steps in a long-lasting roof. Any improperly installed roof is a waste of time, materials, and money. Punctures in a roof or damaged flashing happen, but everyone can avoid an improper installation and improper materials. Once a roof has been installed correctly with the right materials, they are relatively easy and low-cost to maintain and repair.

We not only install single-ply membranes onto existing commercial buildings, we also install offer new construction roofing – that is, roofing for new construction.

Commercial Roof Repair

Not only do we install new commercial roofing, we also repair them. One of the most common problems we encounter is improper installation. When correctly installed, a commercial roof should last at least 15 years. When improperly installed, or if installed in poor weather conditions, problems almost immediately begin to show. What’s more, an inappropriate system can also cause problems. For example, if one installs an EPDM roof onto a restaurant – the cooking fats can prematurely breakdown the membrane and cause problems.

Common commercial roof problems that result in repairs are a lack of maintenance, poor installation, improper roofing materials used, standing water from improper drainage, punctures from debris or walking where one shouldn’t, shrinkage, and damaged flashing and pitch pans.

Whatever the roofing problem is you’re having, we can help.

Commercial Roof Maintenance

Any roof is expensive. And, the last thing any of us wants to do is spend money when we don’t need to. That said, a properly maintained commercial roof lasts longer than a roof that’s been ignored. Your commercial roof should be inspected by a commercial roofing professional at least once a year. Only a professional commercial roofer will know what to look for. Since we offer free inspections, you have nothing to lose. 🙂

A single ply roof should last 15 years or more if it’s not damaged and it’s been properly installed. In addition to regular inspections, if your single ply roof gets the occasional re-coating, it will last a lot longer.
