Pros and Cons of 4 Common Commercial Roofing Systems

Pros & Cons of Commercial Roofing Systems by United Renovations

Given the fact that the roof serves myriad purposes, besides providing cover from the vagaries of the nature, choosing the right commercial roofing system is very important. If you own or manage a multifamily property, installing the right roofing system helps enhance its overall appeal, value, and rentability. Similarly, installing the right commercial roofing system enables industrial unit owners to provide conducive working conditions that positively impact employee productivity. Commercial roofing contractors in Houston offer a number of roofing solutions to help property owners not only cover their properties but also avail specific benefits.

To help you select a commercial roofing solution for your multifamily property or industrial unit, this blog post discusses the pros and cons of four common commercial roofing solutions.


EPDM (Ethylene Propylene Diene Terpolymer) is a synthetic rubber roofing membrane that is popular roofing choice of low-slope commercial property owners and roof consultants for its durability. The roofing membranes are made of ethylene and propylene, resulting in a strong layer that is installed either by blasting or using adhesives. EPDM membranes are 7.5 to 50 feet wide and 45 to 60 mils thick. They are primarily available in black and white colors.

  • Long lifespan
  • Thermal shocks resistant
  • Weather resistant
  • Lightweight and affordable


  • Black sheets attract UV rays, increasing energy costs. Light color sheets are available but are expensive
  • Highly prone to punctures
  • Lacks aesthetic appeal

2. Metal

Metal is another feasible roofing system for your multifamily property or industrial unit. Aluminum and steel are widely popular metal roofing option for commercial properties as they both can hold paint and are less expensive. Copper and alloys are other metal roofing options, if cost is not a limitation. Coating the metal ensures minimum damage from UV rays and moisture.

Most of the commercial roofing contractors employ cold adhesives or torch method to install modified bitumen roofing system. Manufacturer modifies the waterproofing medium, which is usually asphalt with agents such as Atactic PolyPropylene (APP) and Styrene Butadiene Styrene (SBS), to enhance the durability of the roofing system. Modified bitumen is widely applied on properties with low slopes or flat roofs.


  • High strength and durability
  • Wear- and tear-resistant
  • Easy maintenance and repair
  • Flexible, easily expands and contracts


  • Black color absorbs heat, increasing power bill
  • If not performed under expert guidance, roof may catch fire during installation

4. Thermoplastic

Thermoplastic is another popular type of commercial roofing material in Houston. Commonly regarded as TPO roofing systems, it is a perfect blend of PolyPropylene and Ethylene Propylene Polymers. The thermoplastic sheets are commonly reinforced with polyester and sturdy materials such as colorants and UV absorbers. A TPO sheet is 6 to 12 feet wide and 40 to 100 mil thick.


  • Flexible
  • Resistant to punctures and tears
  • Fire and wind resistant
  • Cost less than EPDM and PVC roofs
  • Reflects sunlight, thereby cutting down energy cost


  • Fairly new roofing material
  • Leaks and failed membranes
