Technology advancements have greatly expanded the roofing options for commercial buildings. Each option provides unique benefits and drawbacks, including cost and longevity. It’s essential to understand the difference, particularly for areas such as Florida, where the environment is incredibly harsh.
Here, we’ll explore different types of commercial building roofs in Florida. We will also highlight a few advantages associated with each.
SPF (Spray Polyurethane Foam) Roofing
SPF is among the most eco-friendly options for commercial, manufacturing, and industrial facilities. It is a material made by spraying a combination of isocyanate and polyol resin. The two chemicals react to create a foam-like layer that hardens and adheres to the roof’s surface. It forms a durable and waterproof barrier.
While SPF is not the most popular commercial roofing system, the technology has existed since the early 1960s. It is an excellent option because it provides superior protection even in extreme weather. When properly installed, you can trust that it can serve your facility for over 50 years.
Advantages of Spray Polyurethane Foam Roofing
Durable. SPF is first in liquid form, which expands and hardens into a seamless membrane. This new layer then bonds with the existing underlying roof and eliminates all weak points in the roofing.
It also expands and contracts with the entire facility, reducing any chances of cracks and splitting. Energy Efficient. SPF offers air, thermal, and moisture barriers that deliver the highest R-value per inch.
Seamless and Waterproof. SPF roofing forms a continuous solid surface that does not require screws, seams, and joints. It completely eliminates vulnerable areas that can leak water and moisture.
Renewable. It’s not every day; you just recoated a roof and extended its service life for another 50 years for about 33% – 50% of the initial price. Any other roofing material would require complete replacement at 100% of the original cost.
PVC (Polyvinyl Chloride) Roofing
The PVC roofing system comprises two layers of polyvinyl chloride. In between the layers is a polyester reinforcement scrim. The bottom ply contains plasticizers that provide flexibility for easier installation. It’s also typically darker. The top ply comes with a UV-resistant membrane that offers additional protection from sunlight.
When properly installed, PVC roofs can withstand the most extreme weather conditions. What’s more? They can protect your commercial building for 30 years.
Advantages of PVC Roofing
- Fire resistance
- Visually appealing
EPDM Roofing (Ethylene Propylene Diene Monomer)
EPDM roofing, commonly called ‘rubber roof,’ comprises one membrane of two primary chemicals; ethylene and propylene. The material is a highly durable synthetic rubber offering over 50 years of perfect functionality.
What makes EPDM roofing the perfect roof for commercial buildings is its pliableness. It can absorb shock from impacts like intense hail or storms without fracturing. It also accommodates building movements without breaking or cracking.
Advantages of EPDM Roofing
- Flexibility and easy to install
- Energy efficient
- Low maintenance
- Hail and ozone resistant
Modified Bitumen Roofing Systems
First developed in Europe in the 1960s, modified bitumen roofing has gained popularity in Florida. The roof is a combination of asphalt and unique reinforcing materials like polyester. It resembles traditional built-up roofs but is more flexible and temperature resistant.
Modified bitumen roofing systems get applied in multiple layers in several ways. A professional roof installer can opt for self-adhesive sheets, cold-applied adhesives, torch-applied, or hot-mopped asphalt. The hot and cold options make it viable for installation throughout the years.
Advantages of Modified Bitumen Roofing
- Better in extreme temperatures areas like Florida
- Easy to install
- UV protection and “cool roof” effect
- Durable offering 20 years with minimal maintenance
Metal roofs are a popular choice for many commercial buildings in Florida. They are also one of the oldest roof types, used since the mid-1800s.
Metal roofs come in aluminum, steel, zinc, tin, and copper sheets, offering a variety of options that work depending on the style of your building. Additionally, they work well with all commercial roof types like flat, low-slope, and steep slopes.
Metal roofs offer an attractive finish and can last between 30-45 depending on the material and maintenance. The only downside is corrosion.
Advantages of Metal Roofs
- Fire resistant
- Low maintenance
Also called vegetable roofs, green roofs have become increasingly popular in commercial buildings. They integrate vegetation and a waterproof layer to create an aesthetic roof. (1)
Green roofs are one of the most energy-efficient roofing solutions with various benefits. These include reduced stormwater runoff, improved air quality, and lower energy bills.
Advantages of Green Roofs
- Energy efficient
- Natural insulators
- Increased biodiversity
- Stormwater management benefits
