Polyvinyl Chloride (PVC)
PVC roofing typically falls in the price range of $3 to $5 per square foot. PVC, short for polyvinyl chloride, stands out as a popular choice among commercial roofing materials. This thermoplastic material is derived from salt and oil components. One of PVC’s key advantages is its suitability for structures like factories and buildings dealing with chemicals and oils. Unlike rubber, PVC roofing membranes are resistant to these substances. PVC roofing systems are known for their cost-effectiveness and straightforward installation. They are particularly well-suited for buildings in moderate to warm climates, as PVC can withstand high temperatures without damage, thanks to its reflective white surface. Furthermore, in emergency situations involving fire, PVC roofs don’t contribute to fire propagation, thanks to the cooling effect of chlorine present in PVC.
Glass Reinforced Polyester (GRP)
GRP flat roofing is an emerging roofing material that’s gaining popularity. It’s crafted from polyester fibers reinforced with glass, rendering it highly resistant to corrosion, rot, mold, and fire damage. GRP roofs boast a potential lifespan of up to 20 years and offer affordability compared to other flat roofing options. The installation cost for a GRP roof typically ranges from $4 to $6 per square foot. Its lightweight nature doesn’t burden the structure with excess weight, and it’s fireproof, unlike some other roofing materials that are susceptible to burning.
Thermoplastic Polyolefin (TPO) - A Blend of PVC and EPDM
TPO, or Thermoplastic Polyolefin roofing membrane, is a fusion of plastic and rubber polymers. The installation cost for a TPO roof varies between $3 to $5 per square foot. TPO stands out as an exceptionally flexible material, capable of withstanding extreme heat and cold without succumbing to hail damage. It shines as an energy-efficient roofing option, particularly well-suited for climates characterized by warmth, mildness, or snowy conditions.

EPDM - The Resilient Rubber Roofing Membrane
EPDM, a rubber-based membrane often used for flat roofs and insulation, enjoys popularity in industrial and commercial settings due to its exceptional durability, resistance to chemicals, and ability to brave harsh weather elements, including hailstorms and heavy snowfall. The average cost for replacing a roof with EPDM material can range from $5 to $13 per square foot. EPDM roofs are renowned for their longevity, boasting an average lifespan of 40 years. Their naturally dark color makes them ideal for structures in cold climates, as dark hues help absorb heat. However, for regions with warmer temperatures, it’s possible to opt for a color change with a slight additional cost.
Built-Up Roof (BUR) - A Multi-Layered, Dual-Ply Membrane
If you prioritize a robust, flexible, and enduring roofing solution, the built-up roof (BUR) is a compelling choice. BUR roofing systems consist of multiple layers of roofing materials, starting from the deck and progressing through insulation, asphalt, a cover board, and finally, a protective reflective coating on the surface. BUR roofs can offer a remarkable lifespan of up to 40 years, though they tend to be costlier compared to PVC and rubber membranes. Opting for a built-up system in your commercial flat roof replacement project can entail costs ranging from $4 to $10 per square foot.
Modified Bitumen
Modified Bitumen, also known as mod-bit, is another excellent roofing option. Bitumen, synonymous with asphalt, has been a trusted roofing material for over a century. Modified Bitumen elevates this classic material by incorporating fiberglass and rubber or plastic polymers for added strength and flexibility. The top layer is coated with mineral protection to guard against UV damage and prevent heat absorption. This roofing membrane is particularly resilient and can withstand heavy foot traffic. The cost to install a modified bitumen roof typically falls in the range of $4 to $6 per square foot. Compared to concrete roofs, mod-bit roofing provides a more economical choice for those seeking a robust flat roof solution while managing costs.
Concrete Flat Roof
Concrete flat roofs present substantial weight and installation challenges. They typically weigh around 10 to 12 pounds per square foot and require precise alignment with your existing roof structure. With a lifespan of approximately 50 years, concrete roofs prove to be a cost-effective option for many business owners, especially those with rooftop businesses or frequent roof utilization. The average cost for concrete flat roofs ranges from $4 to $8 per square foot.
Flat Metal Roof
Flat metal roofs are premium choices that offer long-term cost-effectiveness for businesses. The cost of a commercial metal roof falls within the range of $3 to $15 per square foot. Two common types of metal roofing panels are standing seam and nailed-down. Both systems can endure for up to 50 years, with standing seam metal roofs known to withstand the test of time for over 60 years. Metal roofs are a popular choice for low-slope and flat roofs due to their ability to withstand adverse weather conditions and their energy-efficient properties.
Green Roofing System
The growing emphasis on sustainability and eco-friendly business practices has propelled the popularity of green roofing systems. A green roof, also referred to as a living roof, features a top layer adorned with vegetation. This type of roof demands consistent maintenance of its plants and grass. Green roofs offer numerous advantages, including the potential to reduce your building’s temperature by up to 50%, mitigate air pollution in the vicinity, curtail stormwater runoff, and provide insulation for enhanced energy efficiency. The cost of a flat green roof typically falls within the range of $10 to $25 per square foot. It stands as an ideal choice for business owners seeking to advance sustainability objectives and promote environmentally responsible business practices.
To arrive at a more accurate estimate, it’s essential to consider various hidden factors that wield significant influence over the final cost of your flat roof replacement project.
Factors Influencing Flat Roof Replacement Expenses
- Property Size: The dimensions of your property play a pivotal role as larger areas necessitate more extensive roofing. Consequently, the cost is contingent on your building’s size, impacting both labor and material requirements.
- Building Location: The geographic location of your commercial space holds significance, especially in regions prone to storms or extreme temperatures. Such areas often require thicker roofing membranes and more frequent maintenance, adding to the overall replacement cost.
- Roof Pitch: Roof slope matters, as steeper, sloped roofs demand meticulous installation work compared to flat ones. This increased complexity contributes to higher expenses for flat roof replacement.
- Labor Expenses: The pricing range for commercial roofing contractors hinges on their expertise and service quality. Moreover, the location of your building also influences costs, with cities boasting robust competition typically offering lower roofing rates than towns with limited contractor options.
