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.

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.

How We Handle a Winnetka Commercial Reroof
Clear steps keep a reroof predictable from the first visit to the final cleanup. Here is how the project runs.
Inspectors assess the existing roof first, checking membrane, seams, flashing, and deck for moisture and wear. You get a written report with photos before any work is quoted.
Material choice comes next. Single-ply systems like TPO roof replacement and EPDM roof replacement in Winnetka suit most flat and low-slope buildings, and we match the system to your budget and energy goals.
Photo updates track progress through the tear-off and install. Owners with several properties can see our full commercial roofing services for repair and new installation.
What a New Commercial Roof Delivers
Replacing a failing roof does more than stop water. These are the returns Winnetka owners notice first.
-
Lower Utility Bills
Reflective membranes and fresh insulation cut cooling loads across a flat roof.
-
Open Doors Throughout
Staged work around your trading hours keeps customers coming in during the project.
-
Appearance That Fits the Village
Clean edge detail and tidy rooftop equipment matter on Winnetka's visible storefront blocks.
-
Fewer Emergency Calls
A sound membrane ends the cycle of leak calls after every heavy storm.
Predictable, tidy, and built to last, a business roof replacement in Winnetka should cause you as little disruption as possible.
Signs Your Flat Roof Is Ready for Replacement
Roofs give warning before they fail outright. Catching these early lets you plan a reroof instead of reacting to one.
-
Leaks That Keep Returning
Water reappearing in the same spot after each repair points to a failed membrane.
-
Water Sitting After Rain
Puddles still standing two days later signal drainage or slope problems.
-
Seams Pulling Apart
Open or lifting seams across the roof show the system is near its service limit.
-
Patch Costs Adding Up
Several repairs a year usually cost more over time than one planned reroof.
Unsure whether a fix would still hold? Our commercial roof repair in Illinois team can extend a sound roof, and the signs you need a new roof guide helps you judge.

Frequently Asked Questions
Does my roof need replacing or just repair?
Repeat leaks, standing water, widespread seam failure, or a roof past 20 years point to replacement. One isolated fault usually just needs repair. Book a free inspection and we give you a straight answer.
Which system suits a Winnetka building?
TPO and EPDM are the usual choices for flat roof replacement in Winnetka, with different strengths. Our guide on roof flashing covers a detail that matters on every flat system.
Will the work close my business?
Rarely. We stage the site and secure access so your doors stay open while the reroof is underway.
What drives the cost of a reroof?
Roof size, system choice, deck condition, and access all affect it. You receive an itemized estimate after a free inspection, with no obligation.
How long will the project take?
Most projects run from a few days to a couple of weeks, depending on size and system. A prior roof inspection helps us schedule accurately around your hours.
