"I had had a piece of roof facia edge tore away in a big storm in April. I had our roofing company come out to replace it and was assured it would hold. 8 weeks later the same piece tore away in a windstorm again. The roofing company said if they put it up again, it would be the same price and would be put up the same way. I called Triton Exteriors who agreed to to replace it for about the same price and so far it has held up through a couple of strong storms. The installer said the previous piece was not cut and secured properly. Thank you Triton for your excellent service."

"Craig (Owner) and his team were absolutely great to work with. He answered all of my questions throughout the entire project.

I am definitely recommending Carroll Roofing and Exteriors to my family and friends."

"We had a new roof and gutters installed. From the first contact it was a stellar experience. Mark answered many questions his first visit and even looked in the attic to assess the roof from underneath. We had a 30 yr old shingles over the original 20 yr old roof; 2 layers. He quickly came back with the quote, showed us the products and explained what new innovations have occurred since our last install. Had financing options for us to look at and all his preparation led us to using his company. The loan only took 5 minutes to approve. The crew was fabulous and the cleanup was exceptional. The same can be said for the gutter guys. And Mark was here to oversee that things were going well. He wants to do business with you. Overall his company deserves a 10 star rating!"

"Zack and Rob were excellent contractors to work with. The crew they sent out did a great job installing the roof, and the cleanup during and after install was incredible. I highly recommend these guys."

"Our roof needed to be replaced following the May 2025 tornado in St Louis. The job in itself was not super complicated, but there were many moving parts including dealing with the insurance, handling solar panels, etc. These guys did an excellent job, and I would work with them again if I had to start all over. They were particularly good in handling the back and forth with the insurance, and the whole project was completed in a very reasonable time. Most houses in my neighborhood are still waiting for a new roof... "

"Lifetime did a wonderful job repairing shingles and some soffit on my roof. Fully anticipate using them once I replace it."

"Perfect. They were upfront about cost and always let you know where project stood. They also cleaned work area up the only thing they left behind was a repaired roof and a nice looking fascia."

"We called gateway brothers after a hail incident. Our roof was old, and we wanted to get it replaced under our homeowner's policy. Tony explained how the system worked and how we could make the most of the claim. Tony and Aaron are personable and the work they did was exactly what we needed. We had some previous water damage that was not covered by the claim, and they handled that for us as well with a very modest upcharge. We would definately use them again."

"From A to Z, Start to Finish (and beyond) this company and the people involved in my roof repair were nothing short of remarkable. Nathan Snyder was my sales rep and was Fantastic. Knowledgeable, kind, considerate, no hard pressure sales. He just simply stated facts easily to understand and was with me by follow up throughout the entire process. He sent a stand in to meet with the Insurance agent who was INCREDIBLE, Dillon. I really liked the was in which he spoke to and treated the insurance agent, very kind and very considerate. They worked in partnership easily. I also has the opportunity to meet the owner of the company this day--how great that he took the time to introduce himself. Dillon and Nathan went way beyond to find just the right type and color roofing that I wanted (not n their books, so they were able to obtain what I wanted) How many company's extend themself in this manner? The day of install was done by a very competent, efficient, and friendly crew--after they left you would never know they had been there, other than the wonderful new roof! (which neighbors have already raved about) Thanks to Blue Ladder Roofing.--I will be telling everybody THIS is the only company you should use."
