Why EPDM Is the Smart Flat Roof System for Midwest Homes & Additions

Weather-Resistant in All Four Seasons

EPDM remains flexible in extreme cold, resists UV degradation, and handles ponding water better than many other flat-roof options.

Ideal for Residential Additions & Garages

It’s a top pick for low-slope areas where shingles aren’t an option — giving homeowners a clean, low-maintenance alternative.

30+ Years of Performance with Minimal Upkeep

Properly installed, EPDM can last three decades or more with simple inspections and resealing of accessories as needed.

Budget-Friendly Without Cutting Quality

EPDM offers one of the best cost-to-performance ratios in roofing — especially when installed by a crew that understands how to detail it correctly.

Plays Well With Gutters, Flashing & Skylights

We pair every flat roof install with the correct water management systems — including custom edge metal, tie-in flashing, and compatibility with skylights or curb-mounted accessories.

“Flat Roofs Fail When the Details Are Missed. We Don't Miss Details.”

EPDM isn’t a one-size-fits-all solution — it’s a specialty system that demands careful layout, trained installers, and a contractor who sees the whole picture. That’s why builders, architects, and homeowners across Chicagoland and Metro Milwaukee trust Custom Installations.

Greta Harrris

John Robinson & crew was a pleasure to work with: very professional, respectful & competent. They kept me informed of their work schedule at all times & even went the extra mile to address a vent issue that I did not know I had. I would highly recommend using Custom Installations for their quality of work & making the customer feel at ease answering every question. Very satisfied.

Carol Ann B.

My garage I had vinyl siding was done in one day . They did a great job I am so happy i had it done. the crew were working hard all day and the project manager, John Robinson, came often to check on the work. I will recommend this company to my friends.

Jonathan J.

John Robinson at Custom Installations was a pleasure to work with from beginning to end. He was extremely responsive, collaborative and nice, which is rare these days. His team worked diligently for nearly a month. Overall, it was a great experience to work with John and his team at Custom Installations.

Denali

Had Custom installations redo the entire exterior,(hardie board) roof, and gutters of our home and the results were great! Very professional and organized. Whenever I had a concern or question, my point of contact and project lead, John was an invaluable resource and took care of any issues or questions immediately. I was very impressed with his knowledge and ability to communicate my concerns and wants to whatever crew was working for the entirety of the project. Would definitely recommend and use custom installations on future projects.

Ryan Chitwood

I was in need of a metal crew that could do very high end copper work and was recommended this company by a major national player that owns a company in Denver, Co. The people at Custom Installations were amazing from start to finish, literally. They traveled here during the week for work and were so careful and respectful. Their copper/metal work is as good as I have ever seen. They just completed the most beautiful roof we have ever done for a homeowner. Their communication was fluid and consistent and we had zero issues. For a job with a ticket that size, we needed this to be a smooth process and Custom Installations Inc knocked it out of the park for us. Thank you guys!

Rob

Custom Installation was great to work with through this whole process. From the beginning, Ted Aydt Was very professional and thorough with the bid and immensely helpful with the insurance issues. On the job, the whole crew was great and so respectful. John Robinson was The project manager and always kept us up-to-date as did the office staff. I would definitely recommend them for your roofing job.

Will Lynn

Our old siding and part of our garage where damaged due to a storm which resulted in our house needing to be completely re-sided and part of the garage roof replaced. We chose Custom Installation not only for the quality of their work but their skilled teams knowledge of insurance claims. Bruce truly made this entire process as smooth as possible. We could lot be happier with how our house turned out.

Jacob Rosenfeld

We just hired Custom Installations to re-side & re-roof my home. We chose James Hardie, Board & Baton siding. The Custom Installations team was awesome, from my sales contact, Brad Hironimus, to the installers. Despite the house being originally constructed in the 1960's, it now looks brand new and I expect will further stand the test of time. The foreman assigned to our job, John Robinson, was exceptional. He was extremely responsive and always arrived on site with a great attitude. Whenever I had questions or concerns, he was easy to reach and successfully drove the team into delivering a fantastic result. I would definitely refer the Custom Installations team to anyone looking to improve their home.

Robert Tschurtz

We recently had a new asphalt roof installed on our residence here in Wisconsin. Mr. Pohlman and his crew were professional, timely, and exacting in the quality of their work. The project started and ended on time with no issues. Our property was left in the same condition as when they started. Mr. Pohlman was always available by email and personal cell phone for any questions, and personally on site. Overall, an excellent experience all the way around. Very rare these days.

Brett Paschke

The roof looks great and communication from Kevin and team was excellent throughout. Bob and the onsite team were up on the roof in below zero weather getting the job done.

David Held

Danny was able to arrange for contractor to remove the solar panels. He and his crew did a great job reroofing our home.

What Homeowners Ask Us Most

How long does an EPDM roof last?

When properly installed and maintained, an EPDM roof can last 25 to 35 years — sometimes even longer. Regular inspections and minor upkeep can extend its lifespan significantly.

Is EPDM suitable for residential homes or just commercial buildings?

Absolutely. EPDM is a great choice for low-slope sections of residential homes — like additions, porches, garages, and sunrooms — where shingles won’t perform well.

Does EPDM require special maintenance?

EPDM systems are low-maintenance but should be inspected periodically for seam integrity, drainage, and membrane condition. We recommend a check every few years or after major storms.

What’s the difference between fully-adhered and mechanically-fastened EPDM?

Fully-adhered systems are glued down for a smoother finish and better wind resistance. Mechanically-fastened systems use fasteners and plates — typically faster to install and ideal for certain commercial or retrofit applications. We’ll recommend the best fit for your structure.

How does EPDM compare to TPO or modified bitumen?

EPDM offers superior flexibility in cold climates, has fewer seams, and is proven over decades of use. While TPO and mod-bit have their place, EPDM remains a go-to choice for durability and ease of long-term maintenance.
