Different Commercial Roof Types

Certain commercial roof types require certain maintenance and installation processes. Before finalizing your decision, consult with an industry-trusted roofing contractor to decide which membrane roofing material is most suitable for your structure.

The Advantages of Various Commercial Roof Types

Your commercial building needs the best roofing possible to protect your occupants, maintain a professional appearance. Familiarizing yourself with different commercial roof types enables you to make the wisest choice based on your location, budget, and style preference.

Most commercial buildings have flat roofing systems. Since their low-sloped structure is spacious and more easily accessible, these systems are multifunctional and cost effective. Flat roofs also house HVAC equipment and are perfect for building add-ons like skylights to boost energy efficiency and allow natural light into the building. Flat commercial roof types can also be transformed into rooftop patios for meetings, parties, and other on-campus activities. There are many different commercial roof types to choose from, including:



Thermoplastic polyolefin, or TPO, has become a top contender among commercial roofing materials since its introduction in the 1980s. TPO membranes are single-ply roofing systems that offer incredible reflectivity, insulation, and cost effectiveness.

This material’s seamless installation improves water resistance, so property owners can worry less about roof leaks. TPO’s white topcoat creates certified cool roofs, meaning they reflect more sunlight than they absorb to keep the roof cooler. As a result, indoor temperatures remain more comfortable so the AC runs less frequently.


Ethylene propylene diene monomer (EPDM), also known as rubber roofing, is another single-ply flat roof material type. It entered the roofing industry in the 1960s and is still an economical, dependable roofing system to this day. It’s quite versatile, perfect for medical buildings, warehouse roofs, and many other commercial structures. Its flexibility makes it resistant to thermal shock, which is when weather fluctuations cause roofing materials to expand and contract. Plus, it’s made with a chemical self-bonding adhesive or pressure-sensitive seam tape to stay firmly in place.

EPDM comes in large monolithic sheets that are either mechanically fastened, adhered, or ballasted with river rock or a gravel-like layer. This additional layer of protection keeps roofs waterproof and low maintenance. Since EPDM roofs aren’t easily damaged by rainfall, hail, or high temperatures, they often last for at least 30 years before they need to be replaced.


Polyvinyl chloride (PVC) roofing arrived on the scene in the 1960s. This commercial roof type is perfect for more challenging roof deck layouts since its flexibility helps it easily adapt to curves and contours. PVC is most commonly used on restaurants since it’s chemically resistant to fats, grease, and other pollutants.

PVC roofing membranes have either a polyester or fiberglass reinforcement, which helps with puncture resistance and makes them resistant to hail or fallen debris. In the rare event of damage, building owners have extra peace of mind thanks to manufacturer and labor warranties that often exceed 20 years.


Of all the different commercial roof types, metal flat roofs are arguably one of the most beneficial. Metal is naturally reflective, regulating the building’s temperature and lowering utility bills. Plus, though they’re solid and reliable, metal flat roofs are relatively lightweight and easy to install, clean, and maintain for professional technicians.

Metal is one of the oldest commercial roof types on the market. It’s gone through many changes, from copper and lead fabrications to sturdier materials like aluminum and steel. Building owners who choose metal roofing have little to worry about in terms of its long-term structural integrity.
