Are you trying to decide on the best commercial roof types in California? There’s a lot to consider when selecting a commercial roof system for an industrial building, including the type of operation housed in the building and your budget. 

But besides these two important considerations, you also must pay attention to the local climate and commercial roofing codes. So here’s some advice on the best type of commercial roof system for buildings in California.

Best Commercial Roof Types in California

The commercial roofing system on your California building may need to be compliant with California Title 24 and other regulations (i.e. BUR systems are now required to be white).

In addition, your roof system must be able to withstand the following conditions:

  • Extreme temperatures
  • UV rays
  • Snow and ice
  • Wildfires
  • Earthquakes

Are you looking for the best roofing materials for a new commercial roof in California? Here are some to consider. 

Metal Roofing

Metal roofing systems are known for being long-lasting – even in harsh California climates. And modern versions of the metal roof utilize a new fastening system, which reduces the likelihood of rusty screw holes.

Many types of metal roofs exist, including corrugated galvanized steel, copper, aluminum, and stainless steel. They come in a variety of colors and styles and are aesthetically pleasing.  

But besides the visual aspect and being long-lasting and less prone to leaks, metal roofs are a great choice in California because they have a strong fire-resistance rating and are more sustainable than other options. 

Built-Up Roofing Membrane

Built-up roofing (BUR) is made of alternating layers of roofing felt and asphalt. This roofing system is durable, flexible, and more affordable than some commercial roofing systems. 

Another benefit of the rugged BUR system is that it holds up to traffic well. This is especially important for commercial roofs with rooftop HVAC systems and where rooftop snow removal may be necessary. 

Although BUR roof systems aren’t known for being as long-lasting as metal roofs, they can last longer when properly installed and maintained. 

Ask your roofer about how to make your BUR roof more heat-resistant. However, the white BURs (required now in California) may be more costly than some single-ply membrane options.

Modified Bitumen

A modified bitumen system is similar to a BUR system, except that the asphalt used in modified bitumen includes synthetic rubberized polymers. These polymers make the roofing system more resistant to cold temperatures and increase the elasticity of the flat roof

Single Ply Roofing Systems

TPO (Thermoplastic Polyolefin) and PVC (Polyvinyl Chloride) are single-ply roofing systems designed to be used on low slope and flat roofs. Both are designed to conform to the shape and movement of your commercial roof. In addition, they are both light in color and provide a reflective surface, which makes the roofing material compliant with California Title 24.
