"I signed the paperwork and sent the down payment Saturday. By the following Tuesday they were there at 7:00 AM. They completed the job by noon the next day. They did an outstanding job as far as I can tell. I plan on getting the roof inspected by my insurance guy to get a second eye to take a look. But I really liked them and Craig the owner is a standup guy."

"Tim is the kind of contractor you hope to get when cold-calling for a job. We hired Triton to replaced our whole roof,. In the process, Tim's crews found and fixed a stubborn water leak that was tormenting us. First off, Tim and his guys are experts. They are fast, efficient, respectful and clean up well. On top of that, Tim supplies a patient, personal touch that is much appreciated. Especially if you are not familiar yourself with whatever the work involves. He is always accessible for questions or concerns -- before, during AND after a job. I can't stress enough how important that is. He says he wants you to be completely satisfied with his team's work, and he backs that up. We have an 80-year-old, two-story brick house in South St. Louis. We had a stubborn water stain on a downstairs, interior wall. The problem persisted for months, despite the opinions -- and work -- of multiple different tradesmen. Most had done previous -- unrelated -- jobs for us. But this leakage problem persisted. Finally, in need of a new roof, we hired Triton. Before a relative had recommended Tim, we had another roofer replace the original decades-old flashing. We had no history with the first roofer., who was by far the low bidder. But we figured this roofer had addressed the problem. So when the leak persisted, we turned to other craftsmen for possible solutions. We tried tuck pointing, enlarged gutters and fresh interior painting. Nothing worked. Then we hired Triton to replace the whole roof., which involved removing the "new" flashing. Tim's crew quickly found that the original leak was in fact around the chimney -- and that the other roofer's "repairs" to the flashing actually made the leak worse. Tim patiently explained this in detail and documented it with photos. Nearly 18 months later, our interior wall remains bone-dry, thanks to Tim and his crews. What a relief! Along with my own experience, I know that Tim did a great job on an in-law's roof -- that's where I heard about Triton. I'm happy to return the favor and recommend Tim whole-heartedly. In fact, when a female neighbor had an interior water leak like mine,, she hired him at my suggestion. She told me the other day that Triton had fixed her problem as well -- though I'll let her supply her own recommendation! In our case, Triton was not the cheapest option. But I found the hard way that cheaper is not always better. To me, it was worth paying more for expertise, quality materials -- and peace of mind."

"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!"

"Our roof was at least 15 year old and it had been over 5 years since our last inspection so we had Richard come out and see if any work was indicated. He came out quickly inspected our roof and said that we had no damage and reassured us that we likely had another 5 years on our roof. We greatly appreciated his honesty! Will definitely have him back."

"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 was able to scope out our roof project, provide material options, and a quote faster than the other 4 local companies we considered for our 1,200 sq ft roof replacement were able to simply schedule a visit to / and examine our roof. The project manager (Tom B.) was unbelievably responsive, kept us fully informed through every step of the process, and made sure we had a full understanding of the services we'd be receiving. Besides the exceptionally fast and communicative project management, Lifetime was among the most affordable options we considered. I can't recommend them highly enough, and if you have a chance, ask to work with Tom B!"

FAQs for flat, foam, or single ply roofing installation and replacement projects in O Fallon, MO

Many roofing pros point to PVC as the top performer on flat roofs thanks to its tough seams and long-term waterproofing. A properly installed PVC membrane can last 30 years or more, resisting ponding water and harsh weather with ease. You will pay more up front than you would for EPDM, but the added durability often translates into fewer repairs and a lower cost per year of service.

Yes, a rubber roof is an environmentally friendly choice. Most rubber membranes contain recycled content and can reflect heat, which helps trim cooling bills in hot weather. Manufacturing has a lighter footprint than many traditional materials, and the long lifespan means fewer tear-offs headed to the landfill. If sustainability is a priority, ask your roofer about brands that carry third-party eco-certifications and confirm they meet local environmental standards.
