Commercial Roofing in Houston: The Most Common Materials

Initiating the construction of a new building? Commercial roofing in Houston is available in so many different types and materials that sometimes, the information can overwhelm you, making it difficult for you to come up to a decision. But don’t worry, because we have it all sorted out here.

Commercial Roofing in Houston: The Most Common Materials

If after reading through this, you still have questions, then please reach out to a professional company that offers commercial roofing in Houston.

Generally, when deciding a suitable option for commercial roofing in Houston, you should consider several factors like lifespan, maintenance, and obviously, the cost involved. With every building, you do some sort of customization, but more or less, a lot of is about the material that is being used.

Let’s take a look at what choices you have for commercial roofing in Houston, what makes them good, and what would make you consider something else.

This is one of the most lightweight commercial roofing types in Houston. Comprising of both poly vinyl chloride or PVC and thermoplastic polyolefin (TPO), this kind of roof has a highly reflective surface which offers a great amount of resistance to wear and tear, punctures ultraviolet light and most of the chemicals. The seam strength is excellent, making thermoplastic roof suitable for second generation appliances.

Thermoplastic commercial roofing in Houston can be installed using three different application methods. A mechanically attached system is one in which the roof membrane is attached to the deck using mechanical fasteners. A fully adhered system is used when using mechanical fasteners aren’t feasible; in such a system, the roofing material is directly bound to the membrane substrate or insulation board. Considering a point fixed system, the roof membrane is welded onto plates, which are fixed at specific intervals.

A thermoplastic roof is one of the most affordable options that has a lifespan of up to 25 years if maintained well.

Ethyline Propolyne Diene Terpolymer (EPDM) is another option for commercial roofing in Houston. A typical EPDM roof comprises of flat pieces made from synthetic rubber that are joined at the seams, and forms one continuous membrane. The material offers a resistance to ozone, weathering, UV light, and abrasion. The material can withstand extreme weather conditions and can be used for second generation applications; these features make EPDM one of the most environment friendly and sustainable options for commercial roofing in Houston.

Considering the application, EPDM commercial roofing in Houston can be installed through three different means. Of these, a ballasted system is the most economical and easy to install; hence, it is preferred for around 35% total installations. Generally, a ballasted system is preferred for large new projects, but in some cases, it can serve as a replacement if the building can accommodate ballast weighing around 10 to 12 psf. A mechanically attached system is lightweight and can be used for any building, regardless of the size; the roof membrane is directly attached to the deck through mechanical anchors. If fasteners cannot be used, then EPDM roof is installed as a fully adhered application, in which the material is directly affixed to insulation or the substrate. Fully adhered applications are usually the best choice for special constructions like barrels and domes.

Generally, an EPDM roof can be expected to last for around 10 to 25 years if proper maintenance is conducted by a professional company that offers commercial roofing in Houston.

Asphalt is the most traditional material for commercial roofing in Houston. The roof is often coated with gravel, which if not applied properly, leads to issues when sealing the connection points and the seams.

Early roof leakages and frequent maintenance become a potential possibility later on. However, advanced asphalt forms don’t require any extra coating.

Asphalt roofs are quite heavy, and may even require reinforcing of the building structure itself in some cases. Repairs are time consuming if the roof has been coated with gravel because the material hides potential leaks. Plus, gravel should be kept away from the gutters and drains. But gravel is still necessary because it deflects UV light, strengthens the roofing material, keeping it in intact, and offers a resistance to fire.

Initially, asphalt roof was affordable, but prices have increased due to rising oil prices. The lifespan is around 10 to 25 years.

Modified Bitumen
Also, known as SBS or APP, modified bitumen roofs evolved from asphalt roofing systems. The material consists of asphalt along with other minerals, solvents, and modifiers. Modified bitumen offers a resistance to expansion/contraction after being exposed to ultraviolet rays. The material can be connected together through several means in order to form a complete roofing system.

If the torch process is used, the asphalt sheets are melted and then used for creating a seal. Cold applied and self-adhesive application processes may also be used.

Modified bitumen is more expensive than other options for commercial roofing in Houston. The lifespan of these roofs are roughly around 25 years, but factors like sun exposure, roof slope, and decking can reduce this.

A metal roof is made from a variety of materials like stainless steel, lead, tin, aluminum, copper, and galvanized steel. For colder regions, this roof is one of the most durable options. Metal is often recycled.

Insulation is an important consideration because metals are generally good conductors of heat. Plus, they are prone to rusting as well. However, protective waterproofing, heat reflective, and anti-rust coatings can increase the life of these roofing subsystems.

As for the costs, they vary significantly with the material being used, whereas the lifespan depends on how well the roof is maintained.

Photovoltaic Solar Panels

These roofing systems are considered to be a sustainable option. Solar panels are installed over entire rooftops, which then absorb heat from the sun and convert it into energy. Though not a widely-used option, PV solar panel roofs are a good option for minimizing costs in the long run.
