What is rubber roofing?
You might not have heard of rubber as a potential roofing material. But according to the EPDM Roofing Association, this roofing material has been around for more than 40 years.EPDM (which stands for ethylene propylene diene terpolymer) is a relatively affordable roofing option compared to metal, slate and other roof types. Please be advised there are other types of roofing that are made from rubber. What are the different types of rubber used in rubber roofing?
Rubber roofing might refer to any one of three compounds of single-ply, membrane roofing materials. These three compounds are best suited to roofs with low slopes and are EPDM, TPO and PVC. You will also find rubber shingles in the mix. We’ve briefly discussed EPDM, but let’s look at this material and the others more closely.
EPDM.
This synthetic rubber is used in many applications and has become an essential material in the roofing industry. EPDM is an extremely durable material used in low-sloped buildings, residential and commercial, worldwide. Its two main ingredients are ethylene and propylene. You can find EPDM roofing in black or white and a broad variety of widths between 7.5 feet and 50 feet. The thickness of EPDM is available in 45 and 60 mils.
Roofers install EPMD either mechanically attached, ballasted or fully adhered, sealing the seams with specially formulated tape or liquid adhesives.
Note: For the purposes of this article, we will be focusing primarily on EPDM rubber roofs.
TPO.
Thermoplastic polyolefin (TPO) has been on the market for decades, and you will recognize it easily since it is white and most commonly used on commercial rooftops. This material offers excellent energy savings among single-ply membrane roofing materials. Although these roofing systems are largely intended for commercial use, they are worth including here to get a full picture of rubber roof materials. PVC.
Another strong, durable and stable rubber material that works well for flat, low-slope roofing jobs is polyvinyl chloride (PVC), a high-quality way to protect commercial buildings. This material’s cool reflective properties provide resistance to discoloration and damage from the sun.
What are the advantages of a rubber roof?
In addition to its affordability, some homeowners may also choose this roofing alternative because of its ability to withstand harsh weather, including strong winds, hail, UV rays and fire. This type of roofing is also relatively easy to install, maintain and fix, which means you may save money on roof repairs and have more peace of mind in the long run.
Historically, rubber roofs have been used primarily on commercial buildings; however, homeowners may consider an EPDM rubber roof for their residence — especially if they have a low-slope or flat roof. With a flat or low-slope roof, water can quickly pool and cause damage to your shingles. A rubber roof has water-resistant properties that can handle pooling water better than your typical asphalt roof.
Due to their insulating properties, EPDM roofs are also energy-efficient and can help you maintain a cooler roof and home, possibly lowering your energy bills in the process.
If you’re not sure if EPDM rubber roofing is right for you, chat with a local contractor about your other roofing options and get a few cost estimates before you decide. Not sure if you should install an EPDM, TPO or PVC rubber roof? Ask local contractors near you. Material and labor costs for rubber roofs.
When you receive several EPDM roofing cost estimates, you’ll likely see how the material costs compared to the labor costs. Here’s a quick look at the average costs for both:
Labor cost
| Average cost per square foot | Average total material cost* |
|---|
| $1.69-$2.83 | $4,235-$7,095 |
Material cost
| Average cost per square foot | Average total material cost* |
|---|
| $1.69-$2.83 | $4,235-$7,095 |
*All figures represent costs for 2,500-square-foot roofs.
On average, you can expect to pay $5.67-$7.53 per square foot for installation costs. Here’s a look at how much you can expect to pay:
| Roof size | Estimated average cost* |
|---|
| 1,000 sq. ft. | $5,670-$7,530 |
| 1,500 sq. ft. | $8,505-$11,295 |
| 2,000 sq. ft. | $11,340-$15,060 |
| 2,500 sq. ft. | $14,175-$18,825 |
| 3,000 sq. ft. | $17,010-$22,590 |
