CJS roofing did an outstanding job on my roof project. The storms that swept through our region in March 2025 did a number on our house. The shingles were damaged and the insurance adjuster recommended replacement. We got 4 bids over several weeks from reputable St. Louis based businesses. CJS Roofing was chosen based on their bid and reputation. Their contract was thorough and addressed our roofing needs. It also explained the costs should additional hidden defects be present, such as rotted roof sheathing. No added frills or high pressure by their representative. Just basic questions about what we needed or wanted performed, what type of roof materials, and explanations of the differences in product lines. Very informative. Because of the high demand for their services, there was a waiting list. All the reputable businesses we contacted are stacked up, but quality and pricing are very important. When they came out to perform the work, they started around 7 am and finished by 3 pm. Our home is a ranch style over 2200 sq ft under roof. The roof looks beautiful, and the property was free of any debris when they were finished. I can only give CJS Roofing compliments for our experience with them. Their pricing and quality are outstanding! read more

Honest, fair, and excellent work. CJS has a great team that get the job done in a timely manor.

CJS Roofing recently replaced my mother's roof, and we couldn't be more pleased with the results. They were recommended by a neighbor who has used them twice and spoke very highly of their work--and now I understand why. From the first interaction to the final cleanup, the entire process was seamless. They went above and beyond to help me meet a tight deadline, keeping me well-informed and reassured through every step. The crew arrived on time, got straight to work, and impressed me with their professionalism and efficiency. The job was completed by early afternoon, and when they left, there was no debris--just a beautiful new roof that we absolutely love. We can't recommend CJS Roofing highly enough. If you're looking for quality craftsmanship, dependable service, reasonable pricing, and a team who truly cares about the customer, look no further. read more

We entered into a mutually signed and negotiated contract for $11k to complete some of the work needed on our roof after a hail storm in Nov 2024. After patiently waiting 6 months for CJS to honor that contract (because of weather and winter) in June 2025 it was time to do the actual work CJS came back to us and had increased our contract to $24+K an increase of over 118%. This is exactly the kind of shady contracting we feel consumers need to be aware of. I would highly recommend avoiding this company read more

We had a wonderful experience working with CJS, from the initial consultation to the final inspection. They are experts in their field, knowledgeable, and prompt in communication. They delivered the quality materials we wanted and installed them in a single day! We are very satisfied with their service and highly recommend them to anyone who needs a new roof! Thank you, Chris and Denise. read more

I had to have a new roof and gutters due to a hail storm. Working with Chris and Denise made everything so very simple. They worked with the insurance all the way and all I had to do was wait to have it done. The workers were topnotch . They did their work and were out of here before I knew it. What I expected would last two days because I had a double roof was only one. Both roofing and gutter crews cleaned up to the point there was nothing left. I would highly recommend CJS Roofing.

CJS does quality work for a great price, absolutely no problems. Denise handled the insurance end of things smoothly and efficiently. The proof is definitely in their roofs! read more

I will try to make this short.. But CJS Roofing was one of the best contractors that I have worked with. Between Chris, Ryan and Denise they were all there to answer any and all of my questions. The day before the job, Ryan called me to let me know they would be there around 6:15. Sure enough, they were at my house at 6:15 with the first person on the roof by 6:21. These guys worked quick and diligently and had our new roof fully on by 11am. They were cleaned and packed up by noon. I would highly recommend this local, family owned and operated company to everyone... and I do every time I hear of someone talking about needing a new roof. read more

CJS Roofing did an amazing job replacing our roof, and roof on the shed. If you are looking for a roofing company, look no further. Mike came out and inspected the roof, and it was damaged from the March 2024 hail storm. He made another trip to our house to work with the adjuster and the claim. Denise, assisted me with the insurance claim, and walked us through the entire process. I could not have done this on my own! The crew that came out, had the old roof off and new roof on in less than one day. The cleanup after the installation far exceed our expectations. Mike made another trip back to inspect the roof. I am truly amazed with the customer service, the easy of getting a roof replaced with insurance claim. The roof turned out absolutely gorgeous. read more

Used CJS to replace our 20+ year old roof in June, 2023. All members of the team were professional, answered all of my questions, and dealt with the unexpected very well. We were very satisfied with the quality of the installation and the clean up after they finished the work. They came back the next day to finish up some detail work and made sure we were happy. Definitely worth considering this family run company for your roof. read more

I highly recommend CJS roofing. They replaced my neighbor's roof and did a fantastic job! When I needed my roof replaced I called them. Chris and Denise are just wonderful to work with. Denise ask what color shingles I wanted I really wasn't for sure some type of gray. Denise made a few suggestions and Chris brought me samples. I went with one of colors she recommended. My roof turned out great a fantastic color! I felt the quality was great the price was fair and they really care about their work! We had a storm in my area a several shingles came off my roof. I was already on the schedule but I was very concerned that my roof would start leaking due to the missing shingles. I called and spoke to Denise and expressed my concern she assured me they would what ever they could to get me scheduled as soon as possible and they did! I have been having some other type of repairs made to my home. It is very difficult to find people that I feel I can trust and get a fair price. Thank you Chris and Denise for the fantastic customer service and quality work!! read more

I worked with CJS for a new roof and gutters. They were easy to contact and set-up the replacement right away. They were on time, did the job and cleaned up where I didn't know they had been there. They also put me in touch with someone that could assist with some flashing that needed to be repaired. Very helpful. Every thing was great and I would highly recommend them to anyone needing roofing. read more

We had used CJS 10 years ago to install a new roof in South County. We thought CJS did a great job. Quality shingle, expertly installed. At that time, a neighbor came over and asked Chris to look at her roof, she thought she might need a new one. Chris got on her roof, came back down the ladder and told her "you don't need a roof but there are some flashing areas that need caulking". He went back up and caulked. Told her no charge since he was standing in my yard anyway. Two years ago we moved to Wentzville. We were warned by the house inspector that there were multiple issues with the shingle job the builder had put on. After living with it for two years (and praying during every wind storm that multiple shingles would not tear off) we figured we would have to bite the bullet and replace. I called, figuring they might not work this far out in St. Charles. I was thrilled that they were happy to give me a quote. Once again their crew was fast, efficient and friendly. The roof looks fantastic. They installed ridge vent at the same time. My wife and I are happy to have peace of mind in the frequent wind storms Wentzville encounters. Thanks to Chris, Ryan, Denise and their crew! Highly recommend! read more

Chris Sielfleisch and CJS Roofing did an excellent job replacing my mom's roof. They coordinated with the insurance company at each step to make certain that she was properly reimbursed, and kept us informed all along about what would happen next. They delivered the shingles on Thursday 19 November, and started work the following day. By day's end on Friday 20 November, they had finished the work and had thoroughly cleaned up all the debris. They came by the following Monday morning to make sure the job was satisfactory in every way. Each team member was outstanding, and the entire process was perfectly choreographed. It was a pleasure to do business with them. I highly recommend CJS Roofing. read more

Couldn't be happier with our experience with CJS roofing. Professional, no nonsense advice, worked with our insurance company, and made the whole process of replacing our roof and gutters rather painless. Many members of our family have used them, and have nothing but good things to say. Highly recommend!!! read more

We had a new roof put on and they installed larger gutters on the front of the house. Started when they said they would. Finished when they said they would. It took as long as they said it would and we paid the price they said it would cost. Fast, efficient with no surprises and the rood and gutters look great. I highly recommend them. Great job. read more

Great experience with CJS. A true example of a business focused on the people rather than "the job." CJS came out and gave us an estimate with no pressure, push, or expectation on us to go with them. They answered all our questions with professionalism and understanding. And they were supportive throughout the entire process! Oh yeah...the roof work was fantastic as well! Highly Recommend! read more

I called CJS initially to check for recent storm damage to our roof. Chris was out the next day and verified not only that we didn't have any damage, but that our roof was in great shape for its age. Because we had had some ceiling leaks from the flashing of our 30+ year old skylights, Chris offered to quote us on their replacement. Chris was quick to provide an estimate and kept in touch throughout the process. The new skylights look great and I no longer worry about further leaks. When the time does come to replace our roof, we will definitely reach out to CJS. read more

We contacted CJS roofing about installing vents in our roof. Chris emailed me back with two estimates, one for vents and one for ridge vents. Both prices were reasonable so we went with the Ridge vent. we didn't need to be home. They did the work in one day and mailed us a bill and we paid. Very helpful and friendly and there was no mess when we got home. Never knew they were there except for the new ridge vent on our roof. I recommend them highly! read more
