A Guide to the Cost of Flat Roofing Materials for a Roof Replacement

Are you thinking about replacing your roof? Or maybe you recently bought a home, and it needs a roof replacement?

Knowing how much to spend on specific roofing materials can seem impossible. But it doesn’t need to be!

By considering a few simple things, you’ll be able to budget for flat roofing materials!

Let’s take a look at what you should keep in mind.

Built-Up Roofing (BUR)

The linear foot cost of BUR averages between $4-$7, with the majority of prices coming in on the lower end. BUR roofing is typically assembled with four layers of roofing material that are combined to form a weather-proof membrane. The four layers consist of:

  • asphalt
  • a top sheet or mat (which acts as a base)
  • two membranes of reinforcing fabric
  • another layer of asphalt

The top, weatherproof layer is composed of mineral granules such as sand or slate. The cost of BUR materials is generally lower than that of other roofing materials, such as asphalt shingles, metal roofs, and tiles.

Modified Bitumen

MB is composed of asphalt and a polymer to help improve waterproofing ability, life expectancy, and fire retardancy. MB is an economical option for roof replacement, with the cost of materials ranging from $2 to $14 per square foot. The range in cost is based on material type, thickness, and additional features like fire retardancy.

Installation costs are typically in the range of $6 to $15 per square foot. MB roofing is an ideal choice for flat roofs, as it is easy to install, low maintenance, and resistant to water damage. It is available in many styles and colors.

TPO (Thermoplastic Olefin)

TPO Thermoplastic Olefin (TPO) is an increasingly popular roofing material due to its strong resistance to UV rays, its low permeability to air and water, and its relative cost and durability. This roofing system is considered among the most cost-effective roofing options available, with an average cost per square foot ranging from $5.50 for non-reinforced to $8.50 for reinforced systems.

When installed properly, TPO systems are 20-30% less expensive than other popular flat roofing alternatives such as Modified Bitumen and EPDM rubber. It is important to make an appropriate cost-benefit analysis before choosing a new roof.

EPDM (Ethylene Propylene Diene Monomer)

EPDM Ethylene Propylene Diene Monomer (EPDM) is one of the most commonly used flat roofing materials in this type of project. The cost of this highly durable, synthetic rubber material can vary considerably, depending on factors such as the size of the roof, its configuration, and the desired thickness of the rubber membrane.

The materials cost between two and five dollars per square foot, making it a relatively affordable option for those looking to replace their flat roof. However, EPDM is more expensive than some materials. It is more durable, energy-efficient, and able to withstand more extreme climates.

Choose The Best Flat Roofing Materials That Suits Your Home

Fat roofing materials often come with a higher initial cost; however, they typically last much longer than traditional labels. The cost can vary depending on the type of material, the size of the space, and the location the roof is covering. Despite the cost, flat roofing materials are often well worth the investment for their durability and longevity.

Consider the flat roofing option next time you and your family are investing in a roof replacement.
