Flat Roofs Fail Quietly Until They Don't
Flat and low-slope roofs don't shed water the way pitched roofs do. That means water sits longer. Over time, even a small weak spot turns into a leak. Then the damage spreads to insulation, ceilings, and walls. By the time you notice it, the repair bill has grown.
The right roofing system makes all the difference. Our team installs and maintains systems that keep water out for the long haul.
Rubber Roofing in Bourbonnais, IL
What is rubber roofing, and why is it a smart choice? Rubber roofing, also known as EPDM, is a synthetic membrane used on flat and low-slope roofs. It's lightweight, flexible, and highly resistant to weather. A well-installed rubber roof can last 25 to 30 years with minimal maintenance.
It's a popular choice for commercial buildings, garages, and additions. It's also one of the most cost-effective flat roofing options available.
Our rubber roofing services include:
- EPDM rubber roof installation
- Rubber roof repair and patching
- Seam and flashing repair
- Full rubber roof replacement
- Roof inspections and maintenance


Modified One-Ply Roofing Systems in Bourbonnais, IL
What is a modified one-ply roofing system? A modified one-ply system uses a reinforced membrane made from modified bitumen or similar materials. It's stronger and more puncture-resistant than standard rubber roofing. It handles temperature swings well, which makes it a solid choice for Illinois winters and summers.
These systems work well for commercial, industrial, and larger residential flat roofs. Jim Brosseau Custom Roofing has installed and serviced these systems for decades.
Our modified one-ply services include the following:
- Modified bitumen roof installation
- One-ply membrane repair and replacement
- Seam welding and flashing repair
- Maintenance programs
- Storm and wind damage repair
Frequently Asked Questions
What is the difference between rubber roofing and modified one-ply?
Rubber roofing uses an EPDM membrane and is great for basic flat roofs. Modified one-ply systems use reinforced materials that offer extra strength and durability. We can help you choose the right one for your building.
How long does a rubber roof last?
Most rubber roofs last 25 to 30 years. Regular inspections and minor maintenance can help push that lifespan further.
Can a flat roof be repaired instead of replaced?
Yes, in many cases. If the damage is limited to one area, a repair is often the right call. We'll inspect the roof and give you an honest recommendation.
Do you work on commercial flat roofs?
Yes. We handle flat roofing for commercial, industrial, and residential properties of all sizes.
Do you offer free estimates?
Yes. Call us at 815-939-2935 and we'll come out at no charge.
