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.

After the siding, roof, and gutters got pummeled by hail, I received a recommendation for JSMM through a family friend.

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.
