    ACI installed a roof on my home in 2022. They issued a 10 year warranty at completion of the job. The roof has been leaking for the past several months. I have reached out to them several times with email as well as phone calls over the …

    I would not recommend using this company. A company that isn't honest and doesn't pay their registration would worry me. Truck had a well over 2 year expired tags.

  • 1 out of 5Scott Schubbea year ago

    I hired ACI to replace my roof due to hail damage in the spring of 2024. Nearly a year later, the project remains unfinished. I have attached photos showing some of the damage caused by their team while working on my property, as well as a poor attempt at replacing flashing—after their work intentionally damaged the previously undamaged flashing. Unfortunately, the owner has consistently ignored my attempts to communicate. If anyone at ACI sees this, I would greatly appreciate a return call, text, or email. Thank you.

    ACI storm chased my property and I set up an appointment. During the inspection they stated they are there to assist the customer during the insurance process and are customer focused, and offered almost unbelievable warranties. After the inspection appointment, I requested 2 more inspections on 2 other properties. They stated they would get right on it when they arrived back at the office. I heard nothing. After a week I called and emailed. This was the company that I was going to have replace my storm damaged roof, gutters, and siding. However, they don't even remember me. I only recieved any communication, after I gave a 1 star review.

    ACI Exteriors worked with us to repair or replace roofing, gutters, and siding that was damaged from a hail storm. They were responsive to our needs and schedules. They were great to work with.

  • 5 out of 5Carter Rethwisch8 months ago

    Shawn and his crew were great. They managed working with the insurance company. We had renters coming in and they got it done in time. It looks great. Thanks ACI!

    Our HOA contracted with this roofing company and I just wanted to say how professional and thorough they are. I appreciate these qualities and they are deserving of 5 star rating!! Thank you.

  • 5 out of 5Chloe Florea10 months ago

    Joe is a great guy! Highly recommend working with this company!!

  • 5 out of 5Rick Kidd11 months ago

    ACI acted quickly and efficiently in taking care of our roof claim. Shawn came over right away and inspected our roof. ACI worked well with our insurance company, and their installation crews worked tirelessly to finish the tear off and replacement in one day. The gutter crew followed the roofers and then the window wrap crew finished us up. I would gladly recommend ACI for roofing and exterior needs. They are First Class Professionals.

    Absolutely phenomenal service! Britton and his team couldn’t have been more helpful

  • 5 out of 5Johnson Vlogsa year ago

    I haven’t had the opportunity to personally have aci do work on my house but Britton was incredibly professional and helpful. Even though I didn’t need work at the time when I am ready I will make sure this company gets my business!

  • 5 out of 5Sofia Finleya year ago

    Great company! Very helpful as well!

  • 5 out of 5Robert Bruhya year ago

    ACI Exteriors sent a roofing crew that put in a long 12hour day to complete the job in one day. They not only did a great job on my roof replacement but an excellent job cleaning up when finished. They left my yard spotless.

  • 5 out of 5Eric GroningerEdited a year ago

    Some difficulty communicating but nice people and they stand by their work. Had an issue with the roof leaking. It took some time to fix but it was done. Currently waiting on an estimate for future work.

  • 5 out of 5Greg Greenleea year ago

    We had a great experience with ACI. Shawn was quick with providing an estimate and explained everything to us up front. Quality of work was excellent and they didn't try to up-sell us on anything we didn't need. You won't find a better "bang for your buck" than ACI. I have a new patio that will need a roof soon and there is no doubt in my mind who I will call for the job.

    Reply from the business

    Thank you, Greg! We're so glad to hear you had such a positive experience with Shawn and the team. It’s always our goal to make sure our customers feel confident in their choices without any unnecessary upsells. We’ll be here whenever you’re ready for that patio project!

A quick inspection now can help prevent a small problem from turning into a much bigger one. If your home was recently hit by strong winds or severe weather, ACI Exteriors is here to help with a straightforward, no-obligation inspection. 25 years of serving St. Louis and surrounding communities. #ACIExteriors #StormDamage #RoofInspection #Roofing #RoofRepair #RoofReplacement #StLouisRoofing #MissouriRoofing #StormDamageInspection #Homeowners4 days agoLearn more
