Commercial Roofing and How it Differs to Residential Roofing

Commercial roofing is roofing that is usually found on warehouses, shops, factories, and restaurants. As such, commercial roofing differs from residential roofing in that the surface area is much larger than a residential roof’s size, and its slope is either very low or the roof is completely flat.

Due to the flatter pitch of a commercial roof, there is an increased risk of drainage and moisture complications over-and-above its larger roof size, which is why commercial roofs are made from different materials to those of residential roofs. In addition to this, commercial roofs often have heavy air-conditioning vents, HVAC blowers, extractor fans, smokestacks, skylights, and industrial pipes resting on them, which means that they need to be built differently and sturdier to minimize openings from these heavy objects, which are not typically found on residential roofs.

Commercial Roofing Materials

The materials that are used in commercial roofing are dependent on the type of commercial roofing chosen, as well as budget and weather concerns.

Due to most commercial roofs being low-pitched or flat, they are covered in several layers of roofing materials, usually made up of insulation, decking, a protective coating, and coatings that reflect the sun. Due to these multiple layers, as well as the significantly larger size, commercial roofing systems comparatively take a longer time and a more complicated skillset to install. They also take a little more maintenance compared to residential roofing systems.  

This is one of the reasons why it is so important to select a commercial roofing contractor that is fully qualified to install commercial roofing systems, as their installation, maintenance and repairs are much more complex. We at Aegis Construction Group are able to help!

Commercial Roofing Options

Modbit (Modified Bitumen)

Modbit (also known as modified bitumen) is a type of membrane roof that is constructed with multiple layers. It is primarily asphalt-based and is designed to endure tough weather conditions.

Modified bitumen roofs are made up of five layers, which consist of the following:

  •       Insulation layer: This is to provide thermal endurance, and ensures that the roof system’s temperature remains stable, thereby stabilizing the temperature within the building.
  •       Modified base sheets: These form the foundation of the roofing system and provide stability to the system.
  •       Modified bitumen membranes: This is a sheet membrane, which is made up of various polymers and is strengthened with fiberglass or polyester.
  •       Adhesive: This is the layer that provides waterproofing and contains a bonding agent which is either applied through heat (such as torches) or with cold press methods.
  •       Surfacing: This layer provides protection from the sun’s UV rays, as well as weather-resistance. Modified bitumen roofs can either be granule-surfaced, foil-surfaced, or a combination of both types of surfacing, where granule-surfacing is used on the flat part of the roof, and foil-surfacing is used as part of the flashing.

Modified bitumen roofing is a widely used method of commercial roofing, mainly due to its proven track record of performance. This type of roofing also holds up well against water, and has high tensile strength and tear resistance, making it able to withstand foot traffic for maintenance purposes. In addition, with fluctuating temperatures from hot to cold, this type of roofing is flexible and can expand and contract without losing its shape.

EPDM Roofing

EPDM (ethylene propylene diene monomer) roofing is also known as rubber roofing. This type of roofing is made from a rubber membrane and is extremely robust. EPDM is available in black or white, and the white membrane that is installed over the black membrane acts as additional UV protection, by reflecting sunlight.

EPDM roofing is comparatively cheaper to install compared to other commercial roofing options. In addition, it is also easier to repair, mostly due to the fact that EPDM rolls are extremely wide, which results in less seams that can fail on the roof’s surface area. This means that the potential for leaks in an EPDM roof is rare.

EPDM roofing is also lightweight, quick and easy to install, and lasts a long amount of time. This type of roofing is also hail and ozone resistant. It is also highly wind resistant, which is a good choice for the windy city of Chicago.

TPO Roofing

TPO stands for thermoplastic polyolefin and is a type of single-ply roofing that is both energy efficient and reflects heat. TPO membranes come in black, and gray, but are traditionally white, so as to allow for the best reflection of UV rays and to direct heat away from the building.

Similar to EPDM roofing, TPO roofing is made of thermoplastic rubber layers that are reinforced with materials such as fiberglass, carbon fiber or talc, which makes TPO strong but also flexible and able to move with thermal expansion and contraction as temperatures fluctuate during the seasons.

TPO is an environmentally friendly type of roofing, as it does not contain chlorine. In addition, it is fully recyclable. TPO is also easy to maintain, as it is resistant to mildew and algae, and so will not require pressure washing. Installation of TPO is also relatively simple and offers options for installation from adhesives to heat welding for difficult spots on a roof where openings and projections may be present.
