What are the different types of commercial roofs?

A commercial roof has the same basic purpose as a residential roof to protect the contents and people inside. There is one definitive difference though, a commercial roof has a lot bigger area to cover.  Other differences between a commercial roof and a residential roof are the design and type of roof, and what materials are used to cover the roofs. 

The choices in a commercial roofs are many today. Depending on the structure itself and the typical weather will determine which commercial roof type is right. There are also many commercial roofing contractors out there too. A good contractor will work with you on the roof type and materials to make sure you get the best one for your structure.  The different commercial roof types are: 

  • Flat Commercial Roofs: A commonly used commercial roof solution because it is a cost-effective option compared to a pitched or steep roof slope option.  Flat commercial roofing minimizes wasted space, offers energy conservation, especially when the right roofing material is used, and needs minimal maintenance. A flat commercial roof can have almost any type of roofing material, with thermoplastic polyolefin (TPO) being the most popular in Texas. Other commercial roof materials include PVC,  EPDM , BUR, and modified bitumen. 
  • Low-Sloped Commercial Roofs: This type of commercial roof is installed on apartment buildings, factories, and warehouses. It offers a seamless water runoff and provides safe working conditions for the employees. The same varieties of roofing materials are used on this type of commercial roof, but because they don’t hold up to heavy loads of snow, they aren’t popular in snow-bound regions.  
  • Metal Commercial Roofs: This style of commercial roof provides an extended lifespan in comparison to other types of commercial roofing. It is cost-effective, provides optimal protection, is eco-friendly, and re-roofing is simple with the retrofitting process.

What are commercial roofs made of?

 There are 3 popular choices in commercial roofing and waterproofing for commercial structures, each having benefits and each having drawbacks. What is best for each building can vary based on several factors: 

Single-Ply Membrane

A time-tested commercial roofing option that is also used on industrial and manufacturing structure.  This rubber material of EPDM or TPO is installed in sheets that are either ballasted, chemically adhered, or mechanically fastened together and to the structure. 

For tight budgets, this is an ideal commercial roof material that will last up to 30 years when installed and maintained properly. An EPDM materials has a long track record and building owners can decide to add insulation or not. With a Class A Fire rating, it is lowers insurance costs and with the high reflective nature, the TPO version is a white surface and helps to lower energy bills. 

Spray Polyurethane Foam 

SPF commercial roof material is an eco-friendly roofing material used on commercial, industrial, and manufacturing structures. It is a liquid that is sprayed on, then expands as it turns into foam and creates a solid layer.  When SPF commercial roofing is installed correctly and recommended maintenance is followed, it has a lifespan of 50 years or more.  

SPF commercial roofing is energy efficient, offers a high rated R-value, and provides a moisture barrier. This durable material contracts and expands with the structure and the temperature, and as a solid surface, there aren’t any seams to be concerned with leaking. An environmentally friendly material because it can be installed on top of the existing roof, eliminating the need for tear-off materials to the landfill. 

Metal Roofing

Metal commercial roof material has been around forever and today, the choices of metal are many from aluminum, to corrugated galvanized steel to tin. A lightweight material, it can be installed on top of other commercial roof material and a waterproof coating can be included at time installation.

What materials do roofers use?       

Along with most commercial roof contractors, we recommend TPO roofing system for most commercial structures in this area of Texas. The pros we’ve listed here will support that decision: 

  • Cost – A budget friendly material with a white coating that provide a heat-reflective surface with heat-sealed seams. 
  • Energy Efficient – With the white surface and heat reflectiveness, TPO commercial roof coatings keep the interior temperature cooler, so less stress on the HVAC system. A decision that commercial building owners can appreciate during a Texas summer in the long term of budgeting.
  • Maintenance – A TPO commercial roof is a single-ply roof membrane that doesn’t need to be pressured wash. Anti-algae and anti-fungus makes this commercial roof material a popular choice. 
  • Weight – TPO commercial roof material is lightweight with a high performance rating for low-sloped roofs. Because it is light weight, it is an ideal choice for an older building that the structure may be questionable for a heavier roofing material.
