New flat, TPO, and EPDM systems for Winnetka builds and additions.
Putting a new roof on a building is the one stage you cannot revisit cheaply. JSMM Inc. handles commercial roof installation in Winnetka for additions, rebuilds, and full renovations.
Projects here are rarely open fields. Most involve an existing storefront or mixed-use building where access is tight and neighboring businesses stay open throughout.
Working across Winnetka, IL for more than 30 years, we install systems that hold up long after the scaffolding comes down.
Posted on Google Dmytro ChernetskyiTrustindex verifies that the original source of the review is Google. Jonathan did an amazing job with his crew to fix my house. The quality and professionalism is on the highest level. This is the best company in illinois if you are looking to fix your roof or siding!Posted on Google Sokratis KoutelidakisTrustindex verifies that the original source of the review is Google. I used Jsmm inc for my roof and work inside my house, they did amazing job! Jonathan and his crew are focusing on the details, they gave me updates very often and they finished everything in the timeframe that they told me. I will use them in the future for other projects too.Posted on Google Ron HsiaoTrustindex verifies that the original source of the review is Google. I highly recommend Jonathan and his team for your roof repair needs. A couple of weeks ago, we discovered a roof leak that made its way through the ceiling of our bedroom. We called some water mitigation folks to dry out the attic and made the mistake of allowing them to tarp our roof to prevent additional leaking. Even though there affected area was relatively small, they ended up tarping the entire roof. When our insurance adjuster came out, he informed us that because of the holes they put in, we'd likely need the replace the whole roof and that insurance may only cover the small section of roof that was actually leaking, which would mean we would be on the hook for the rest. Enter JSMM. They made quick work of the roof replacement and even identified and resolved the root cause of the leak (improper roof system for the roof angle). Additionally, Jonathan was an excellent communicator and throughout the process, I felt very assured that he had our back. Finally, he was an excellent mediator between us and our insurer. Dealing with homeowners insurance is almost always a pain but with Jonathan in the loop, all of that pain was hidden from me. I didn't need to worry about explaining the situation to the insurer, or about accidentally saying the wrong thing that could adversely affect my claim. He was able to negotiate with the insurer to get my whole roof replacement covered. If what the adjuster said is true, including Jonathan in the project probably saved me around $30k and absolutely increased my peace of mind. No roof leak can be called stress-free but bring JSMM into the mix and it'll be as stress-free as possible.Posted on Google Stephanie DoroTrustindex verifies that the original source of the review is Google. JSMM Inc. deserves 10 stars if this was an option! What an incredible experience I had dealing with them from start to finish on my insurance claim from hail and wind damage! Jonathan, the owner, was exceptionally great. from dealing with the insurance company, to dates and times about material drop off and installation. I literally didn’t have to do anything. He got the most out of the insurance and way more than I expected. Roof, gutters, down-spouts, garage door, soffit, facia, front door and storm door and window coverings. I was ecstatic! all while covering my deductible! His crews doing the install, were kind and courteous and also quick and thorough and everything looks fantastic. Grade A adjuster and contractor and would highly recommend! Final pics to follow!Posted on Google James LeviTrustindex verifies that the original source of the review is Google.

He was able to work with our insurance to get our new roof approved. He walked us through the entire process and we immediately knew we were in great hands. Highly recommend him.Posted on Google Daniel PolivkaTrustindex verifies that the original source of the review is Google. I am incredibly happy with the service provided by JSMM. After the siding, roof, and gutters got pummeled by hail, I received a recommendation for JSMM through a family friend. Johnathon came out and thoroughly explained everything he was going to do to fix up the house. Every single stage of the process was communicated, and I always knew when supplies were going to arrive, and when crews were going to be on site to work. Absolutely phenomenal. I will be walking in my family friend's footsteps, and recommending JSMM to anyone I know who is looking for a top tier general contractor service.Posted on Google Brian DeSimoneTrustindex verifies that the original source of the review is Google.

Roof Systems We Install
System choice depends on the building, its use, and how the roof will be accessed once occupied.
-
TPO Single-Ply
Reflective and energy-saving. Our TPO roof installation in Winnetka uses hot-air welded seams throughout.
-
EPDM Rubber
Handles Illinois temperature swings well. Our EPDM roof installation in Winnetka suits offices and retail alike.
-
Modified Bitumen
Multi-layer coverage where a tougher surface is needed underfoot.
-
Larger-Footprint Builds
Our industrial roof installation in Winnetka and the wider North Shore covers bigger spans and heavier detailing.
Whichever commercial roofing system in Winnetka fits the plans, sound flashing and detailing go in with it. Our full commercial roofing services cover repair and replacement too.
Why Builders and Owners Pick Us
An install sets how long the roof lasts, so the crew matters more than the brochure. Four things set us apart.
-
We Work Alongside Your Trades
Slotting in around framing, mechanical, and finishing crews without holding up the schedule.
-
Permit and Inspection Coordination
Applications filed and inspections booked so approvals never stall the build.
-
Installed to Manufacturer Spec
Every layer goes down to specification, which is what keeps the warranty valid.
-
Our Own Crews, Not Subcontracted
The team quoting the job is the team on your roof, start to finish.
Steady commercial roof maintenance in Winnetka keeps each of these performing, and an annual roof inspection catches faults early. See our full commercial roofing services for replacement work.
How the Installation Runs
Repairs go wrong when the cause is guessed at. Four habits keep ours right the first time.
-
Plans and System Choice
Reviewing drawings, use, and budget to settle on membrane and insulation early.
-
Coordination With Your Builder
Sequencing agreed with the general contractor so the deck is ready when we arrive.
-
Deck, Insulation, and Membrane
Each layer installed in order, with drainage and detailing built in from the start.
-
Sign-Off and Warranty Registration
Final inspection, manufacturer field check, then paperwork filed so cover begins properly.
Registration is the step most often missed, and it can void a warranty later. Avoiding the common installation mistakes matters just as much, alongside proper ventilation beneath the deck.
What You Get With a New System
Getting the roof right at installation avoids problems that are expensive to correct later.
-
Slope designed in from the deck, so water leaves rather than pooling.
-
Insulation values that meet current code and cut running costs.
-
A manufacturer warranty that starts clean, registered and on file.
-
One contractor accountable for the whole roof, not split across trades.
Should an older roof need stripping rather than a fresh build, our commercial roof replacement in Winnetka team handles the tear-off, while commercial roof repair in Winnetka covers existing faults.

Frequently Asked Questions
How long does an installation take?
Anywhere from several days to a couple of weeks, depending on size and system. We work to your build schedule so later trades are not delayed.
Which system suits my building?
TPO and EPDM cover most flat and low-slope work, with different strengths. We recommend after reviewing the drawings, and a roof inspection of any retained structure helps.
Do you handle the permits?
Yes. Applications and inspection bookings are managed on your behalf so the project stays compliant.
What affects the price of a new commercial roof?
Roof size, system, insulation depth, and site access are the main factors. An itemized estimate follows a review of the plans, with no obligation.
Can you install on an occupied building?
Often, yes. Additions and re-roofs above trading premises are staged so the business below stays open.
