    Terrible book keeping and communication.

    If i could give them zero stars i would. They have absolutely no capability of dealing with insurance. They pay for reviews as well. Theres a lot of contractors out there. Use someone else.

    Having worked with Ken before, it was a no-brainer to buy a new front door as well. He went through all of the potential options with us and gave us realistic choices for our style of house. He never tried to sell us something we didn't need. Any questions were promptly answered. Installation went smoothly and it looks great!

    Ken was a pleasure to work with as we began the process of updating our home's exterior. He was friendly, responsive, and took the time to meet us right where we were in our planning — no pressure, just genuine helpfulness. We're looking forward to working with him again on our next home project!

    I recently bought a fixer upper house in Bloomington IL. Knowing the house would need a new roof, I was dreading the process of getting quotes, scheduling contractors, and getting the bill That was until my home inspector recommended Diego from Zag's Roofing. Diego was fantastic, completing a thorough inspection with detailed pictures - highlighting pre-existing hail damage - creating a reasonable quote, scheduling the work. Diego's team was fantastic, arriving at 7 AM on Day One, and working until almost 9 PM. When a surprise occured (almost all of the plywood sheets were compromised) Diego helped negotiate a lower cost for the plywood sheets. His team even stayed three hours late on Day Two to clean up - leaving the yard in a cleaner state than when they arrived! Highly recommend Zag's. I'm extremely grateful to Diego, and look forward to working with him again on our next project!

    Experience, knowledge and kindness. Ken is hard-working and honest and a pleasure to work with. Your go-to for the home exterior.

    I highly recommend Ken Polikov for any exterior project. Ken helped us plan an exterior facelift of our 1960s colonial, which included capping our columns, installing a new front door, and replacing our windows and shutters. He provided several thoughtful options and even suggested a phased approach to help keep the project within our budget. Ken was communicative throughout the process, and the final results exceeded our expectations. I look forward to working with him again in the future.

    Ken and his team were fantastic from start to finish. He was incredibly thorough, walked us through every detail of the project, and made sure we felt confident in our decisions. Communication was clear and consistent, and the whole process …

    I interviewed a few contractors before choosing Zags, and I'm really glad I did. Like most people, I was nervous about spending this kind of money and worried about getting stuck with a mess or dealing with someone who'd disappear after I signed. From day one, Ken treated this like a consultation, not a sales pitch. He walked the property with me, explained what I actually needed vs. what could wait, and gave me a clear plan with transparent pricing—no vague estimates or surprise costs. The crew showed up exactly when promised, protected everything, and cleaned up completely each day. I never had to chase anyone down for updates—Ken and his team communicated proactively the whole way through. Our home looks incredible, and it's already more comfortable inside. But honestly, the best part was how stress-free the whole process was. If you're looking for someone who treats your home with respect, explains everything clearly, and delivers exactly what they promise—call Ken at Zags. You won't regret it.

    Ken, John and their crew were an absolute pleasure to work with on replacing 21 windows in my home. Easy from start to finish. A breath of fresh air when it comes to any type of home project. As a cherry on top, they got three days of work done in two days. 5 stars isn’t enough.

  • 5 out of 5Jessica Min7 months ago

    I'm not one to write reviews but I had such a great experience with Ken. We are in the middle of a major full house renovation and recently had our exterior doors installed. We ran into a few issues with the new doors and I needed an …

    Legendary. Impeccable service and great communication. They go above and beyond - it’s obvious they truly care about their work and their clients. Highly recommend.

  • 5 out of 5Michael Brodsky11 months ago

    Zags Roofing recently installed our new roof and we couldn't have had a better experience. Their team was extraordinarily professional, efficient, punctual, and customer-focused. John, in particular, continually went above and beyond. Not …

    John (see photo) went above (pun intended) and beyond a traditional roofing estimator. He corrected the insurance companies mistaken estimate. He helped after the fact when we needed some documents for our realtor. And, of course he was …
