Ethylene Propylene Diene Monomer (EPDM) roofing is a single membrane roll or sheet of rubber material typically used on roofs with little to no pitch. The material has a wide variety of uses, and as a result, there are many variables when it comes to how much an EPDM roof will cost you.

EPDM is a durable and affordable low-pitch roofing option. EPDM material costs can range from $3 to $12 per square foot but are usually around $4 to $6.50. The cost of EPDM installation adds another $1.50 to $3 per square foot. For a 1,500 square foot roof, expect to pay between $8,000 and $22,000.

The price range for an EPDM roof is incredibly vast due to various factors such as the cost of materials, adhesive, labor, equipment, and many other things. Let’s take a more in-depth look at your options when it comes to EPDM rubber roofing to help you more accurately price out your roofing project.

How Much Does an EPDM Roof Cost?

When planning an EPDM roof install, there are two primary components that you should budget for: material and labor costs. Additionally, there are some costs regarding tools and supplies, but they are much more minor in comparison.

Material Cost
The cost of EPDM roof materials varies widely depending on location, time of year, market condition, and many other factors.

Generally, you can get EPDM rubber membrane rolls or sheets for around $5 per square foot. However, EPDM prices range from as low as $3 per square foot up to $12 or more.

On a roofing quote, you will often see the EPDM material line item price written in terms of squares (1 square is equal to a 10×10 area, or 100 square feet). EPDM rubber square pricing ranges from $300-$1,200, but usually is around $500 per square for most projects.

Labor Cost
One of the most significant expenses you will have when budgeting for an EPDM rubber roof is the labor cost for installation. For many roofing projects, labor can account for up to 60% of the total cost.

Typically, hiring a roofing crew to install an EPDM roof will cost you $1.50-$3 per square foot, equal to $150-$300 per square. If you must remove old roofing before laying down the new, it will typically cost you an additional $1-$2 per square foot, or $100-$200 per square.

Removing old roofing material, replacing damaged sheathing, and putting down insulation (iso board) before installing the new EPDM can prolong the project and add considerable expense.

EPDM is a relatively quick and straightforward roofing material to install, but it is crucial to hire someone who has experience installing EPDM. Residential and suburban roofing companies will often have less experience with the material than companies that regularly work on industrial buildings.

It’s well worth spending more money to have your EPDM roof installed correctly than hiring an inexperienced crew and needing to replace the roof after only a few years. A well-installed EPDM roof can last 50+ years, and failures earlier than that are usually due to improper installation.

Tools and Supplies Cost
When hiring a roofing company to install your EPDM roof, you typically won’t have to worry about the cost of tools. The roofing crew will either bring any additional supplies with them or add them to your quote.

For most EPDM roof installations, budgeting $300-$500 for tools and supplies is sufficient. The installation process for an EPDM roof is pretty straightforward, and you don’t need many expensive pieces of equipment or supplies.

Here is a non-exhaustive list of some of the supplies and tools you may need:

  • Insulation (iso board)
  • Fasteners or nails
  • Adhesive
  • Rollers and buckets
  • Personal protective equipment (PPE)
  • Seal tape or splicing adhesive
  • Flashing and trim
  • Stiff deck broom

How Much Does It Cost to Repair an EPDM Roof?

Dealing with roof damage can be stressful and expensive. The extent of the roof damage will largely determine how much it will cost you to fix, so the table below can give you a general idea of what to expect when repairing an EPDM rubber roof.

Roof Repair ExtentRoof Repair Extent
Small roof repairs$50-$100
Medium roof repairs$250-$500
Extensive roof repairs$1,000-$2,000

Repairing an EPDM roof is pretty straightforward, whether it is a small hole or more significant damage. You can fix most damage to EPDM roofing using small rubber patches and sealant around the edges.

While fixing damage to the EPDM rubber is quite simple, things get more complicated if the structure, sheathing, or insulation below the material sustains damage. If water gets underneath the EPDM rubber outer layer of the roof, it can cause severe water damage, mold, and even electrical issues.

Well-maintained EPDM roofing under favorable conditions can last 50 years or more. Due to the roofing material’s long lifespan, it is best to repair any damage with a patch most of the time. You might consider replacing the entire roof if the damage is irreparable or if it’s over 20 years old and showing severe wear and tear.

Comparing EPDM Roofing to Alternative Materials

For roofs with little to no pitch, there are many roofing material options available. Which one is right for you depends on many factors, including your budget, needs, climate, design, and many other things.

Here is a quick breakdown and comparison of some of the most popular EPDM roofing alternatives:

Final Thoughts

Installing a new roof, regardless of the type, can be an expensive and stressful event. There are many hidden pitfalls and costs to look out for, but hopefully, you now have a little more insight into what to expect regarding the cost of an EPDM rubber roof.
