Choosing the Right Flat Roof

At Grell Roofing, we pride ourselves on staying at the forefront of commercial roofing technologies. Our expertise allows us to recommend the most efficient and effective roofing solutions for each unique project.

Modern commercial roofing products offer high resistance to temperature extremes and enhance environmental efficiency. The choice of a commercial roofing system should be guided by the type of facility and the specific needs of your business.

The Basics

Commercial roofs can be classified into three categories, each requiring different materials.

     Primary Categories:

              •   flat
              •   low slope
              •   steep slope

     Most Common Systems:

              •   single-ply roofing
              •   modified bitumen roofing
              •   built-up roofing
              •   metal roofs
              •   liquid applied roofing
              •   roof coating systems

Further

To further optimize the energy efficiency of commercial roofs and lower utility bills, we recommend the use of insulation and cover boards. When replacing a roof, it’s advisable to add insulation. Single-ply membrane systems, including thermoset and thermoplastic membranes, offer flexibility and resistance to weathering. Various attachment methods are used for single-ply roofing.

Whether you are updating commercial buildings or embarking on new construction projects, the type of commercial roof you choose can greatly impact long-term costs. Contact Grell to learn more about the best types of commercial roofing for your specific building, based on your needs and the design of the structure.

What is the best commercial roofing material?

While we recommend investing in durable commercial roofing systems that provide long-lasting protection, the ideal choice for your business may depend on several factors. Property investors should consider variables such as local weather patterns, aesthetic preferences, maintenance requirements, and the need for roof accessibility. At Grell, we’re here to guide you through these considerations and help you make the best decision for your business.

Polyvinyl chloride (PVC) roofing, is a single-ply membrane used on flat or low-sloped roof surfaces. PVC roofing systems are typically comprised of two layers of PVC film and a fabric scrim that provides strength and durability. While available in a wide range of colors, white PVC roofs offer superior reflectivity compared to darker roofing systems, and PVC roofs are effective in all climates. Additionally, PVC membranes are flexible, lightweight, resistant to most chemicals, and self-extinguish after fire exposure.

Custom-fabrication is the process of manufacturing a product to meet the specific needs of a project. At Grell, we custom-fabricate every roofing system to the exact specifications of each building, eliminating 85% to 95% of rooftop seaming and ensuring an excellent fit and long-term performance.
