This is the best company in illinois if you are looking to fix your roof or siding!Posted on Sokratis Koutelidakis2024-12-12Trustindex 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 Ron Hsiao2024-12-12Trustindex 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 Stephanie Doro2024-09-13Trustindex 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 James Levi2024-01-11Trustindex verifies that the original source of the review is Google.

Highly recommend him.Posted on Daniel Polivka2023-09-19Trustindex 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 Brian DeSimone2023-08-03Trustindex verifies that the original source of the review is Google.

Signs It's Time for a Full Roof Replacement
Spotting a few leaks or missing shingles isn’t always enough. Here are the telltale signs your Lake Forest home needs full replacement, not patching.
-
Multiple missing or curling shingles across slopes
If damage affects more than one side or widespread shingle lifting occurs, repairs will just be a band-aid.
-
Interior water stains, peeling paint, or mold near eaves
These often signal long-term leaks that have compromised decking or insulation.
-
Blistering, sagging, or soft spots on roof planes
Blistering, sagging, or soft spots on roof planes These suggest structural or moisture damage underneath; fixing them piecemeal is risky.
-
Roof age over 20–25 years
Even "good" roofs wear out. Lake Forest sun, storms, and extreme temperature swings age materials faster.
-
Granule loss and bald patches
If your gutters or downspouts are filling with roof grit, shingles may no longer properly protect against water.
Replacing early can save tens of thousands in downstream costs (rot, mold, interior damage). Many local competitors don’t call this out clearly, but we will.
Keep Your Roof Strong Long Term With JSMM Inc.
Annual or biannual inspections
We check seals, flashing, vent collars, gutters, and roof valleys. We catch issues before they balloon.
Clean gutters & downspouts regularly
Debris causes water backup, ice dams, and moisture damage. Let us clear and maintain them.
Trim overhanging tree limbs
Lake Forest has significant tree coverage. Overhanging branches scratch or break shingles, cause excess moss growth, and wear materials prematurely.
Prompt repairs after storms
Even small hail or wind damage should be evaluated. What looks minor today can worsen fast.
Monitor attic or ceiling signs
Musty smells, light through the roof boards, or sudden temperature shifts inside may hint at deeper damage.
We also provide preventive care packages designed specifically for Lake Forest homes near Market Square and the Lake Michigan shoreline, where seasonal conditions can be especially harsh.
