EPDM Roofing
If you’re looking for a durable and cost-effective solution for a flat or low-slope roof, EPDM roofing is a strong choice. At New Era Roofing, we install and repair EPDM roofs for both residential and commercial properties throughout the Sacramento area. With over 25 years of industry experience, we’ve seen firsthand how reliable this single-ply membrane can be when installed properly.
What Is EPDM Roofing?
EPDM (ethylene propylene diene monomer) is a type of synthetic rubber used to cover flat and low-slope roofs. Often called “rubber roofing,” EPDM is known for its flexibility, UV resistance, and long service life. It’s especially common on commercial buildings, but it’s also used on garages, additions, porches, and other flat areas of residential homes.
EPDM membranes are available in large rolls, which means fewer seams, and fewer seams mean fewer places where water can sneak in. That makes it a solid pick for leak protection.
Why Choose an EPDM Roof?
Here are a few key benefits of EPDM roofing systems:
Long-Lasting Protection: A properly installed EPDM roof can last 25–30 years or more.
Cost-Effective: EPDM is more affordable than many other flat roofing options, including TPO and PVC.
Low Maintenance: It requires very little upkeep and can handle harsh weather, hail, and UV rays.
Energy Efficiency: Available in black or white, EPDM can either retain or reflect heat based on your needs.
Flexible Installation: It’s lightweight and can be installed in multiple ways to fit your structure.
EPDM roofs are especially great for Sacramento’s weather, they can handle both hot summer sun and cooler rainy months without breaking down.
EPDM Roofing for Homes & Businesses
EPDM roofing is most often used on commercial buildings, but it’s also a great solution for parts of residential properties with flat roof sections. Common areas include:
Home additions or dormers
Carports and garages
Covered patios
Flat-roofed apartment buildings or duplexes
If your roof has a pitch of less than 2:12, traditional shingles won’t work, and that’s where EPDM comes in. It’s made to handle standing water and stay sealed tight.
Installation Options for EPDM Roofs
There are three ways EPDM roofs are installed:
Fully Adhered: The membrane is glued directly to the roof surface. This method offers the best performance and appearance.
Mechanically Attached: Fasteners and plates hold the membrane down along the seams. It’s quicker to install but can be more vulnerable to wind.
Ballasted: The membrane is laid loosely and held down by heavy materials like gravel. This method adds weight to your roof and is better suited to buildings designed for it.
The method we recommend depends on your roof’s structure, budget, and how much foot traffic the roof might see.
Thickness & Color Options
EPDM membranes typically come in three thicknesses: 45 mil, 60 mil, and 90 mil.
45 mil is the most budget-friendly but offers less protection from punctures.
60 mil is the most common and provides a great balance of durability and cost.
90 mil is ideal for heavy-duty use or areas with harsher weather conditions.
You can also choose between black or white membranes. Black helps absorb heat and is great for cooler areas, while white reflects sunlight and keeps indoor spaces cooler, a smart choice for Sacramento’s hotter months.
The Downsides of EPDM (And How to Avoid Them)
Like any roofing material, EPDM isn’t perfect. It can shrink over time if not installed correctly, and it’s possible to puncture the membrane with sharp objects or heavy foot traffic. However, working with an experienced EPDM roofing contractor in Sacramento, like New Era Roofing, helps prevent these issues.
We install EPDM the right way the first time, so you don’t have to deal with costly repairs later on.
EPDM Roofing FAQs
How do I know if EPDM is right for my roof?
EPDM is ideal for flat or low-slope roofs where water tends to pool. If your roof has a pitch below 2:12, EPDM is likely the right material. It’s also a smart choice if you want something long-lasting, low-maintenance, and cost-effective.
Does EPDM work well in hot climates like Sacramento?
Yes, especially if you choose white EPDM. The white version reflects heat and helps lower indoor temperatures. Black EPDM is also an option, but it absorbs more heat, which may raise cooling costs in warmer areas.
What happens if my EPDM roof gets a tear or puncture?
Small punctures or tears can usually be repaired quickly with patch kits or sealants. The key is catching the damage early. That’s why regular inspections (especially after storms) are important to keep your roof in good shape.
Will the EPDM roof look okay from a second-story window?
EPDM roofs are sleek and clean-looking, but they can collect dirt over time, especially white membranes. If your roof is visible from above, we can walk you through aesthetic options to make sure you’re happy with the look.
How much does an EPDM roof cost in Sacramento?
The cost for EPDM roofing typically ranges from $9 to $17 per square foot for smaller areas, and $7 to $12 per square foot for larger jobs. Factors like membrane thickness, installation method, and added insulation will affect your total price.
