Commercial Flat Roofing

Commercial Flat Roofing in Dallas, TX

Builders occasionally put in an inappropriate roof on buildings with flat roof structures (as opposed to low-slope or steep-slope systems). Because they are unaware of all the decision-making criteria necessary to select the best roofing material from the wide range of available possibilities, inexperienced roofing contractors and novice building owners install commercial flat roofing systems that are subpar.

More frequently than not, a building’s history was marked by changes in the nature of the businesses operating inside.
And while the building’s original commercial roof might have been ideal for its previous use, it might now be inappropriate or simply too old and causing leaks inside the structure.

No matter what, it’s critical to comprehend the fundamental characteristics of how the flat roofing system on your building is made so you may make more intelligent decisions about preventative maintenance, repairs, and potential replacement in the future. You may learn a little about the common flat roofing materials that may already be installed on your roof in today’s post, as well as how to assess whether
you have the ideal roof for your company.

Which Flat Roof is Best?

In conclusion, it can be difficult—or even impossible—to provide a general response to this topic. The type of business you perform inside the building may frequently determine which roofing system is appropriate, even if there are many commercial buildings of almost comparable structure situated in regions with similar climatic circumstances. Of course, additional elements like the owner’s budget will also have an impact on the final decision.

Constructed Roofing (BUR)

Built-up roofing is one of the earliest commercial roofing systems that still has value in some new installation scenarios from today. A continuous, semi-flexible membrane consisting of felt or layers of fabric is a feature of BUR systems (called plies). BUR roofs are commonly referred to as “tar and gravel” roofs because roofing contractors alternate plies with layers of other asphalt-based materials such hot tar/bitumen and aggregate.

BUR systems are incredibly robust and can be repaired rather easily. Although they usually don’t need much maintenance, we do advise twice-yearly checks to make sure it’s leak-free and doing its job of shielding your structure. For many flat roofs, BUR roofing systems are a reliable roofing option.

TPO and PVC Roofing

Reflectivity is a key advantage of PVC (polyvinyl chloride) and TPO (thermoplastic polyolefin) roofs. These roofs frequently offer strong chemical resistance and are white.

PVC might be the best roofing material for a restaurant or a facility that produces food because it actively resists chemicals like oils and fats that might be emitted onto your rooftop.

Roofers install TPO and PVC roofing by unfolding the rolls it comes in, adhering or mechanically attaching the material to the roof deck, much like they do with all single-ply membrane roofing. TPO and PVC roofing employ heat to weld seams and make the roof impermeable, in contrast to EPDM roofing, which we shall discuss next. Although the two-step installation technique seems straightforward, it is labor-intensive and demands expertise.

EPDM Thermoset Roofing

EPDM thermoset roofing can be the ideal choice for your commercial building if you’re seeking for a commercial flat roofing material with exceptional fatigue and scratch resistance. Ethylene propylene diene monomer, also known as EPDM, is a substance that resembles rubber. These systems may be referred to by roofers as “rubber roofs.”

With its “tried and true” technology—which professionals have used for more than 50 years—EPDM has an advantage in the market.

What’s best? Many of those first EPDM roofs are still in use today and can withstand most anything Mother Nature throws at them.

The EPDM roof membrane is very long-lasting. It offers commercial flat roofing systems long-term protection.

Because EPDM is normally black, it is not reflecting, but light-colored ballast might affect how efficient it is. When getting their roof fixed,
many building owners with EPDM roofs add the light-colored coating to improve the building’s energy efficiency.

Modified Bitumen

Modified bitumen is a different method that is frequently referred to as “rubber roofing” (MB). Similar to BUR, MB is a layer-based commercial flat roofing material that has a petroleum-based component in between each layer to give it a rubberized appearance and qualities.

Because MB roofing is significantly thicker than certain single-ply membranes, it can withstand regular foot traffic, which is one of its many advantages. In comparison to BUR or even TPO, it is also easier for commercial flat roofing contractors to install because it frequently doesn’t call for the usage of heat.

Instead, self-adhering “cold process” sheet material makes up the majority of MB roofing. It can help safeguard buildings by saving energy because it is highly robust and reflective.
