Houston Commercial Roofing Systems

We Are Ready To Create a Roofing System For Any Type of Roof

Your roof is arguably the most important part of your building. Without it, you are exposed to the elements, debris, and other factors that would otherwise make the building uninhabitable. You, therefore, need to choose a roofing system that protects both the inside and outside of your building. Selecting the right roofing material is not an easy process, as there are several factors to consider. You want to be thorough with making your choice as buying and installing the roofing material is a significant and one-time investment.

The Different Types of Commercial Roofing Systems in Houston

Built-up Roofing

BUR roofing is even older than modified roofing, with installations beginning in the mid-1800s. Like modified roofing, BUR involves the use of bitumen installed with alternating layers of felt to form up to 4-ply systems. The main difference is that the bitumen is pure and is heated up to 400 degrees before being poured and spread onto your roof using specialized safety equipment. The felt is applied onto the liquid, and as soon as it solidifies, the roofing experts can add another layer of bitumen or a top layer of granules such as gravel placed on it to protect the system from the sun.


BUR systems have quite the track record, being 150 years old. They are excellent for flat roofs seeing plenty of foot traffic and guarantee excellent protection from water as they are puncture-resistant.

EPDM Roofing

If you are looking for a more modern roofing solution, consider EPDM (ethylene Propylene Diene Terpolymer) as your commercial roofing material. EPDM is a recent invention, a single-ply rubber membrane that is installed onto the roof using a hot glue gun or adhesives. EPDM materials come in black or white sheets that you may have seen on many commercial flat or low-sloping roofs.


EPDM has been increasingly popular among business owners for its cost-effectiveness. Our roofing experts will help you find an EPDM material supplier who offer high-quality and authentic EPDM from trusted sources, so you get maximum value for your money. Another reason for its popularity is energy-efficiency. Thanks to its white color and poly-iso insulation, it is able to reflect plenty of the sun’s energy and maintain heat inside the building, thus keeping your AC costs low.

Like any other plastic material, EPDM is completely water-resistant, and if well installed, its seams will be as well. Therefore, you can use it for a rooftop garden. It is also fire resistant, meaning that EPDM can slow down the progress of a fire. If you are looking for a chemical-resistant, tough, and cost-effective roofing material for your factory to last up to 20 years, EPDM is an excellent choice.

Houston Metal Roof

Metal roofing has been the top commercial roofing systems for years, especially for hangers, industrial complexes, and warehouses. Regardless of the metal you choose, metal roofing delivers quality protection from the elements. Our commercial roofing Houston TX crew will use the best installation methods to ensure maximum protection from the sun’s heat. We offer aluminum, zinc, galvanized steel, copper, tin, alloys of aluminum, zinc, and silicone, and metal tile sheets.


While metal roofs are not the best choice for a building housing employees for the loud noise they make when it rains, they offer durability and longevity, with a proper installation lasting up to 40 years. Metal roofs are also preferred for their aesthetic value, delivering a minimalist neutral finish to a high-slope roof. Metal roofing is also eco-friendly, as most of them are made up of up to 95% recycled material, and after their long life as a roof, you can recycle them again.

Modified Bitumen Roof

Modified bitumen is one of the older commercial roofing systems, with its popularity starting as early as the mid-70s in the US. It is still one of the most popular roofing systems for flat and low-sloping buildings. Modified roofing is essentially a kind of bitumen reinforced with a polymer. Our commercial roofing contractors Houston will install it by alternating layers of the bitumen with layers of reinforcing fabric and felt through hot or cold application methods.

Modified bitumen can be reinforced with atactic polypropylene (APP), resulting in a thermoplastic plastic-like form of bitumen that will be heat-welded or torch-applied to your roof. The second polymer is styrene butadiene styrene (SBS), which gives bitumen a rubber-like appearance. This second type of bitumen is installed using a cold adhesive or hot asphalt moppings.


This kind of roofing is long-lasting, offering 20 years of service with little maintenance. Modified bitumen is also robust against water and severe changes in temperature. Most clients also prefer it for its energy efficiency and strength due to polymer modification.

PVC Roof

PVC is another of the single-ply commercial roofing systems, which is more plastic-like than the other two. PVC (Polyvinyl Chloride) has been around for the last 50 years and is best installed on flat or low-slope roofs. It is installed using a hot air gun with polyester layers acting as a support substrate.


PVC is a durable roofing material, with most systems lasting about 20 years. Moreover, since its seams are hot air-welded together, they will remain intact throughout its life as the bonds formed will be as robust as the material itself. PVC, like other plastics, is resistant to water, acids, greases, and other caustic chemicals you may have on the roof. It is also resistant to fire as plastics do not support combustion, and have been known to withstand winds as strong as a category 3 hurricane. PVC roofing is also recyclable and reflective of the sun’s energy, making it eco-friendly and energy-efficient.

TPO Roofing Installation

TPO (thermoplastic Polyolefin) is another relatively new single-ply rubber roofing membrane. The major differences between TPO and EPDM are their chemical structures, mode of installation, and degree of energy efficiency. TPO is also the more popular roofing membrane, taking up about 40% of the commercial roofing systems market. TPO is a synthetic membrane that is bought in white, red, blue, or pink 10, 12, or 20-feet-wide sheets. 


Like EPDM, this single-ply rubber membrane roofing is inexpensive. Even better, the installation process is cheap, unlike that of EPDM, which might be slightly expensive. TPO, unlike many other roofing materials, offer a wide range of colors to choose from. You also select several insulation options, including poly-iso, expanded polystyrene, and extruded polystyrene. If well installed, TPO can last 30 years. TPO is also class-A fire –resistant, highly reflective of the sun’s energy, and water-resistant.
