McStay Quality Roofing & Solar is your reliable source for any commercial roofing needs. Typically, a low-slope or flat roof (dissimilar to most residential homes that have much more significant slopes), commercial roofs differ from residential roofs in a few other ways: the necessary materials differ, the installation process, and the plans for maintenance. No matter the application, though, McStay Quality Roofing & Solar has the expertise and the experience to make sure that your roof is of the highest quality.

Roof Replacements

Fortunately, commercial roofing technology has improved greatly over the years, and many business owners are happy to find that their roofs can last a very long time! Eventually, though, there will come a time when your roof must be replaced. McStay Quality Roofing & Solar has the experience and expertise to support your commercial roofing replacement needs. Give us a call today, and we can make a plan together!

Flat Roof Repair

While the 3 primary types of commercial roofing (built up, modified bitumen, and single ply) are all strong, durable roofing systems, they will each require some level of repair at some point in time.

Although the name would suggest otherwise, flat roofs are never completely flat as some degree of slope is required for drainage purposes. Even so, the flatter nature of “flat roofs” and “low-slope” roofs does invite its most common problem: water collection (also known as “ponding”).

While the 3 main types of commercial roofing systems have fundamental characteristics that combat the issue of ponding, no roofing system is inherently immune to this issue. It is worth having our professionals at McStay inspect your roofing system to determine whether your roof requires repair.

Signs or events that may indicate that your commercial roof may need some expert-level attention:

  • Degrading seams
  • Bubbles (which can form between the top layer of your roof and the layer just beneath it)
  • Consistent leaking issues caused by standing water
  • Hailstorms, tornadoes, or other severe weather
  • Clogged drains
  • Gaps in roof’s flashing
  • Rising energy bills (as this might indicate a reduction in the reflectivity of your top coating)

Modified Bitumen

Modified bitumen (also known as “mod bit”) is one of the most popular commercial roofing system options. It is durable, leak-resistant, and cost-effective. Three different application techniques are possible when installing modified bitumen: heat-welding, hot asphalt, or cold-adhesion. Lasting up to 20 years with regular maintenance, modified bitumen is a solid choice for your commercial roofing needs.

If you have a modified bitumen roof and you believe that your roof requires some repair, good news: modified bitumen roofing systems are also easy to repair.

Single Ply

Installation and Repair: Single-ply roofing options have improved over the last several decades. Particularly for flat and low-slope commercial applications, roofing materials have migrated towards far more durable options with much easier maintenance.

Types of Single-Ply Roofing

McStay Quality Roofing & Solar offers 3 different types of prefabricated single-ply membranes that support flat and low-slope commercial applications: EPDM, PVC, and TPO. Read on for more information on each of these single-ply membranes.

  • EPDM Roofing: Ethylene Propylene Diene Monomer (EPDM) is a durable and low maintenance single-ply roofing membrane. EPDM Roofing refers to single-ply low-slope roof systems where sheets of EPDM rubber are joined together to make a waterproof roof membrane. EPDM is available in both black and white, and it is sold in a broad variety of widths.
  • PVC Roofing: PVC (polyvinyl chloride) Roofing is a singly-ply white membrane used in both commercial and residential roofing. Because it is white, the membrane actually reflects heat, which saves the property’s air conditioning unit from having to work as hard! (By the same token, it also saves your wallet!)  This robust material also offers protection against chemicals, water leaks, UV rays and fire. Thanks to its cool reflective properties, PVC is resistant to damage and discoloration from the sun’s radiation.
  • TPO Roofing: TPO (thermoplastic polyolefin) consists of recycled rubber, and it is sold in rolls that are held together by seams glued together using welding. Similar to PVC, it is white and highly reflective, offering a potential reduction in air conditioning costs. An eco-friendly, low-maintenance, and lightweight option for your roof, TPO offers some great benefits that you should consider!
  • Repairs: Single-ply roofing solutions are incredibly durable, and they withstand all of the elements of occasionally severe and unpredictable Texas weather very well.


SPF (or Spray Polyurethane Foam) is a high-performance material that begins as a sprayed liquid that transforms into an expanding foam. The resulting foam creates a solid layer across the roof. The SPF roofing system option serves as a strong, lightweight, and very protective membrane.

Additionally, no matter the existing material, SPF can serve as part of a roof repair project for your current roof, which, in effect, lengthens its lifespan. SPF adjusts well to various temperatures and weather thanks to its inherent flexibility, and because of its foam nature creating an insulating barrier, the energy efficiency of your roof and building are also improved.

SPF roofing application can last up to 50 years in the North Texas region!


One option for roof restoration projects is strategic and professionally applied roof coating materials. Coatings offer a seamless and waterproof solution to the majority of common maintenance and restoration needs. There are several coating options that, while all serving the same overall function, would each offer slightly different benefits. Our roofing professionals at McStay would be able to walk you through all of the options for your particular project.


Acrylic coating is very durable, cooperative with most existing roofing systems, and highly reflective (improving your roof’s energy and your energy bill). Application of an acrylic coating is extremely simple, and it can last up to 15 years before requiring another coating. 


Elastomeric coating is applied in liquid form that hardens to become a durable, flexible membrane. The differentiating factor for elastomeric coating in the North Texas region is that it functions very well in extremely high temperatures, so the difficult summer months in North Texas will not affect the functionality of this coating.


Polyurea coating is a fast-setting coating that can be applied in multiple layers to achieve the desired thickness. Chemical-resistant and durable in all types of weather, polyurea also provides a robust deterrent against corrosion and rust.


Silicone coating responds particularly well in situations where high UV radiation is an issue. It is possible to reduce your energy bill by almost 40% with a silicone coating!
