Commercial Flat Roof Systems Types
What flat roof system is best for you? These are the most common options.
EPDM
Ethylene Propylene Diene Monomer (EPDM) roofing is made of industrial-grade synthetic rubber and is known for its durability and suitability for low-slope roofing.
The flat roof surface is strong and resilient, able to resist UV light and accommodate expansion and contraction with temperature changes. EPDM has been used on commercial flat roofs for over 50 years.
Maintenance: While EPDM membranes are robust, they can be susceptible to splitting if they come into contact with sensitive materials. Regular checks and periodic cleaning are necessary to maintain the EPDM surface. It is also important to ensure proper drainage of the roof surface.
Lifespan: A properly installed and well-maintained EPDM system can last over 30 years.
Cost: The cost of EPDM roofing ranges from $3.25 to $14.75 per square foot.
The choice of roofing materials and the brand used can significantly impact the lifespan of the roof.
TPO
Thermoplastic Polyolefin (TPO) is a common single-ply membrane used in the US. The membrane is made from polypropylene, ethylene-propylene, or rubber. The material is rolled into large rolls, and the seams are welded using hot air. While the standard TPO material is usually white, it can also be produced in various colors such as gray, tan, or custom shades.
Maintenance: A TPO roof system requires regular cleaning and inspections to ensure long-term durability. Proper drainage is also essential for TPO roofs, just like any other type of roof system.
Lifespan: With expert installation and consistent maintenance, a TPO system can last up to 30 years.
Cost: TPO roof systems typically range in cost from $3.50 to $14 per square foot.
When considering roof replacement, it is advisable to select a commercial roofing contractor with a high rating.
PVC
PVC roof systems share similarities with TPO, as both feature polyester reinforcements, hot air welded seams, and a range of color options. PVC’s top layer contains additives that provide resistance to UV rays and chemicals. PVC roofs are durable, flexible, and relatively easy to install compared to other roofing systems.
The PVC system is fire-resistant and is available in various thicknesses, widths, and colors, with reinforcements included.
Maintenance: Like other single-ply membranes, PVC membranes require regular cleaning and inspections. It is crucial to have a properly functioning drainage system to extend the life of your PVC roof.
Lifespan: With proper maintenance, a PVC roof can last up to 30 years.
Cost: The cost of PVC roof systems typically ranges from $4 to $12 per square foot.
Building owners are advised to trim back any trees that overhang their buildings to prevent falling branches from puncturing single-ply roofs.
Modified Bitumen & BUR Flat Roof
The built-up roofing system (BUR) has been in use for a long time. It consists of three or four layers of roofing felts that are adhered with hot asphalt adhesives.
Modified Bitumen (MB) is a modernized version of BUR roofing. It combines asphalt with a polymer chemical to improve flexibility and temperature resistance. Both BUR and modified bitumen have thick membranes and coarse surfaces, making them highly durable. They can also withstand heavy foot traffic due to their granulated surface.
Maintenance: BUR systems require less maintenance compared to other roofing materials because of their multi-layered structure. Petroleum-based products can become brittle and dry over time, so it is advisable to have a professional inspect your roof at least twice a year.
Lifespan: Modified bitumen roof systems typically last between 20 to 30 years.
Cost: The price of a modified bitumen system ranges from $9.50 to $14.50 per square foot.
Regular maintenance will not only reduce the risk of injuries but also save your company money on equipment damages and costly shutdowns. If you have a BUR roofing system, it is important to ensure proper maintenance is carried out.
Metal Roofing
Metal roofs have been utilized for many years in commercial buildings due to their durability and long lifespan of up to 30 years. However, it should be noted that metal roofing systems tend to be more expensive compared to other types of roofs.
Maintenance: Regular inspections and ensuring proper drainage are necessary to maintain a metal roof system. It is also essential to take measures to prevent falling debris from damaging metal panels.
Lifespan: Metal roofs with adequate slopes can last 30 years or more if proper installation guidelines are followed.
Cost: The cost of metal roofing typically ranges between $8 and $18 per square foot.
Metal roofs are available in a variety of colors and styles, making them suitable for commercial buildings such as malls, apartments, and hospitals.
