Pitched roofs are designed to let rain and other precipitation slide off. Flat roofs have limited drainage, making it easier for water to build up and cause damage. This is why rubber roofing is a good choice for low-slope roofs. Evan Greene, Sales Manager of Northeast Exteriors for the New England Branch of Long Home Products, explains that PVC membrane roofing is better in low-slope roofing because it can handle water pooling better than metal or asphalt, which are two of the other choices for low-slope roofing.

Rubber’s waterproofing properties make it more difficult for water to enter your home than other roofing materials. It’s also weather—and fire-resistant and requires minimal upkeep. Installing a rubber roof usually costs $7,000–$23,000. This guide covers frequently asked questions about rubber roofing and breaks down other cost factors.

What Is Rubber Roofing?

Most rubber roofing is made of single-ply membrane or long, single-layer sheets of thermoplastics. These membranes are almost exclusively installed on flat roofs or low-slope roofs since these styles need more waterproofing than pitched roofs. The rubber roofing membrane comes in rolls that are adhered, screwed, or ballasted to the wood or metal roof surface.

Rubber shingles are an alternative to common asphalt shingles for pitched roofs. These shingles are typically made of 75%–95% recycled tires and other plastics. The installation process is similar to other types of roof shingles. Rubber shingles cost more than single-ply membranes, but they’re more durable.

What Are Common Rubber Roof Membrane Types?

There are multiple types of synthetic rubber membranes. Each type has different pros and cons.

TPO

Thermoplastic polyolefin, or TPO, is a relatively new roofing material. It was invented in the 1980s and first used on roofs in the 1990s. TPO must be welded with a heat gun, making it more complicated to install and maintain than other membrane types. TPO roofing is available in multiple colors. Those in warm climates can choose white roofing for improved energy efficiency.

Pros and Cons of TPO

Pros

• Affordable
• Long-lasting, heat-welded seams
• Surface reflects UV rays

Cons

• Complex installation and maintenance
• Shorter life span

EPDM

Ethylene propylene diene monomer (EPDM) is the only true synthetic rubber typically used in roofing. It’s also the earliest type of rubber roof membrane, so it’s been well-tested over the years. With proper maintenance, it can last up to 60 years, and it usually lasts at least 20.

Pros and Cons of EPDM

Pros

• Easy to install
• Long life span
• Resistant to fire and hail damage

Cons

• Glued seams may leak
• Only comes in black, which retains heat

PVC

Polyvinyl chloride, or PVC, is typically the most expensive rubber roofing membrane, but it’s also the most flexible and leak-resistant. Unfortunately, as it breaks down over time, it releases dioxins and chlorine.

Pros

• 20-year life span
• Heat-welded seams
• High weather-resistance

Cons

• High cost
• Less eco-friendly

Pros and Cons of PVC

What Is The Average Rubber Roof Installation Cost?

Rubber roofs cost an average of $7,000–$23,000. Where your roofing project falls within that range depends on the following factors.

• Roof size: Rubber roofs cost $4.25–$14 per square foot.
• Membrane type: EPDM is the least expensive single-ply membrane, followed by TPO and PVC.
• Labor: Labor accounts for about 60% of professional roof installation costs.

Cost by Roof Size

Roofing materials and installation costs are typically priced by square foot, so the larger your home is, the more a new roof will cost. The average roof is about 1,700 square feet. For a project of this size, a new roof would cost $7,225- $23,800.

Cost by Membrane Type

Rubber roofing membranes don’t vary widely in price, but there are some differences. Make sure to balance cost with durability. The less often you need roof replacement, the less you’ll spend over time.

Membrane Type	Cost per Square Foot	Life Span
TPO	$4.50–$14	7–15 years
EPDM	$4.25–$12	20 years
PVC	$5.25–$13	20 years
Rubber shingles	$7.50–$15	30–50 years

Labor Cost

A new rubber roof costs an average of $7,225–$23,800. About $4,335–$14,280 of that goes to labor. Rubber membranes that need to be installed with heat guns will cost more than other types of roofs because of the extra time and skill required.

---

What Are Additional Rubber Roofing Cost Considerations?

Here are some other factors that may impact your rubber roof cost.

Climate

Climates with extreme temperatures or weather may require different, more expensive types of rubber roofing. For example, those in hot climates will likely want light-colored rubber or rubber with reflective coatings.

Old Roof Removal

You’ll need to remove your existing roofing material before you can install your new rubber roof. Sometimes, new roof sheathing is also needed, and this can cost anywhere from $1 to $5 per square foot.

Roof Penetrations

Roof features such as chimneys or skylights that require the roofing contractor to penetrate the rubber sheeting require extra flashing and sealant to remain waterproof. These also require more time to work around, which will increase labor costs.

How Does Rubber Roofing Compare to Other Types of Roofing Materials?

Though there are many factors to consider when choosing a new roof, two of the most important are the overall cost and projected life span of each material. Learn how rubber roofing compares to other roofing material options by gauging both of these factors.

Many of the materials below are extremely common but can’t be used for low-slope roofs. Even if other options are more affordable, you’ll have to stick with either rubber, metal, or asphalt when replacing a flat roof.

Asphalt Shingles

Aluminum Shingles

Cedar Shingles

Clay Tiles

Copper Tiles

Flat Roofing

Slate Tiles

Standing Seam Metal Panels

Steel Shingles

Zinc Tiles

Material	Cost per sq. ft	Life span in Years	Cost Per Year of Use*
Asphalt Shingles	$2.08–$3.50	20–30	$220
Built-up Roofing (BUR)	$3.42–$4.90	15–30	$370
Clay Tiles	$5.90–$14.68	50–100	$275
Concrete Roofing	$5.16–$8.60	50	$275
Green Roofing	$10–$28	40	$950
Metal Roofing	$9–$14.60	40–70	$430
Slate Roofing	$7.56–$18.70	75–200	$190
Solar Roofing	$16.10–$20.85	25–30**	$1,350
Wood Roofing	$6.53–$9.90	15–30	$730

*Cost per Year of Use is an estimate for how much each roofing material costs for a 2,000 sp. ft roof for each year of its life span and is meant to help show the potential value of each option.

**Solar roofing life span is a general estimate due to the technology only being 10 years old.

Your roof’s life span may vary depending on how well you maintain it and various weather and locational conditions. If not maintained properly, your roof may need replacement sooner rather than later. Once again, keep in mind that rubber, metal, and asphalt are your three material choices when dealing with a low-slope roof.

Should You DIY vs. Professional Rubber Roof Installation?

Most roofing projects aren’t do-it-yourself (DIY) jobs. Rubber roofing is usually only installed on flat roofs, so it’s a little more DIY-friendly than shingles, but most homeowners should still hire a professional.

Professional Rubber Roof Installation

It’s wise to hire a rubber roofing contractor—rather than a general roofing contractor—to install a rubber roof. Professionals with experience applying membrane roofing will know how to seal it properly to ensure it’s waterproof. A roofing company is also the best choice for installing roofing that needs to be sealed with specialty heat guns, such as TPO and PVC. This costs more money than doing it yourself, but the project will get done much quicker.

DIY Rubber Roof Installation

You may be able to install rubber roofing yourself in some circumstances. For example, if you’re using glue-sealed EPDM or the building is only one story and has few roof penetrations. However, you risk creating an improper seal that could cause water damage to the underlying roof decking if you don’t know what you’re doing.

How To Save Money on Rubber Roof Installation?

Here are some ways to save on rubber roof installation, even if you opt to hire professionals.

• Compare pricing: Get quotes from multiple roofing contractors. Be wary of any contractors who charge much more or much less than others.
• Complete your project in the off-season: Roofing companies often charge less during late fall or early winter when they’re less in demand.
• Do parts of the job yourself: If possible, remove and dispose of your old roofing materials yourself.
• Opt for affordable materials: EPDM is the least expensive rubber roofing material, but be sure to balance price with long-term durability. Also, carefully review the warranty.

How To Hire a Professional Roofer

Here are some tips for finding the right rubber roofing contractor.

• Ask whether they have specific experience installing the rubber membrane type you want. Are they certified by the manufacturer for installation?
• Verify the contractor’s license and obtain copies of their liability and workers’ compensation insurance.
• Inquire about extra charges for things such as roof penetrations and slopes. The contract should list all items individually.
• Check the company’s Better Business Bureau rating and accreditation status.
• Ask for references and check customer reviews on sites such as Yelp and Trustpilot.
• Get all estimates in writing and ask about the project timeline.

Our Conclusion

It’s usually best to let professionals deal with roof repair and replacement, especially for a specialized material like rubber. We recommend getting at least three estimates from different companies before hiring a contractor. If you decide to take the project on yourself, make sure you know what you’re getting into and take all necessary safety precautions.
