"I’m going to begin this review by saying, I have never hired someone to do a job on my house where I have been completely satisfied with the labor and the finished product. Until now. I just hired a company to remove my existing shingle roof and replace it. Not only is the finished product of excellent quality, but the technicians were extremely diligent in making sure everything was done with precision. The entire job even down to the clean up afterwards is outstanding…. I highly recommend Coxs Roofing and I will be using them whenever I need roofing work done. Oh! And they also had the best price quote out of three estimates I received. 1121 Roland Heights Ave. 21211"

"We had a bad leak. Milton Roofing workers repaired the flashing around the chimney and re-caulked around the roof vents. It has been two weeks since the repair was done. The leaking has stopped. I highly recommend the company. Billy was punctual and easy to work with. The total repair cost was reasonable."

"The guys were very professional and polite, they did a great job. This is the second time we have used them and we would definitely hire them again. They replaced the missing shingles, checked the entire roof, flashings, pipe sealants, and ridge vents. They sealed everything that needed touched up. They also cleaned and tightened up the gutters and downspouts. Once they were done they made sure everything was cleaned up behind them."

"The roofing crew was phenomenal. They did something I have never seen before—they put tarps on all the bushes around the house. In addition to the shingles, they also had to replace all the wood under it. They did beautiful work! They treated our property with the care they would have used on their own homes."

"Bought my house in 2017 and told it had a new roof. Came to find in 2025 that it had been totally botched. Shingles were coming up, there were large holes where knots in the frame had been knocked out by nails, and I had severe water damage on one of my trusses. Roof Pups came out, assessed the damage, worked with me on the price, and in less than a week I had a crew on site that fixed everything in a single day. They were here for over 12 hours making sure the job got done and they did a great job. I couldn't be happier with my experience."

"Very happy with the company very nice people, wonderful service, amazingly fast would most definitely recommend to anyone needing roof repair/ replacement 10 stars for me."

"Company's responsiveness was great, including the visit, inspection, and discussion of repair of roof ridge vent damaged due to storm had samples to show the differences in the ridge vents an samples of my old vent he explained in detail about each and how its installed. They scheduled quickly everyone was several weeks out and Larry @ Reliable Roofing kept in touch of when had availability and working with my insurance company and squeezing us in to their very busy schedule, Larry was a very pleasant person and his crew was too â ¦ they explained what needed to be replaced and repaired and suggested different types and best for your money they were honest, I checked the pricing of their estimate of product and grade difference !! Larry kept in touch with us the whole way thru, A great company I will use them every time I need roof repairs and recommend them to friends and family!! They were in and out quickly and did a great job!! So glad I choose them out of the three estimates! Happy customer :)"

"Overall the installation went well except the "bowing" in the portion of the roof over the garage. We contacted Power on several occasions, but we haven't received a proper response yet. Below is the email we sent to Power. Power did acknowledge receiving the email, but nothing has happen so far. Email: You replaced our roof April 23, 2022 – project number 35-74502. We’re pleased with the replacement except for the portion over the garage…it’s bowing. Below, is our account of the events detailing how we have tried to resolve this issue. March 26, we met with sales team, Chris Pierson and Christy. We were assured that the bowing over the garage would be addressed and corrected since we were getting a brand-new roof, down to the decking/framing. The replacement should resolve this issue unless it’s structural. Brandon, project manager came out March 30 to check the readiness of the installation; to verify the frame could support the new roof. During the appointment, he mentioned that he would be on site the day of install. The roof was replaced on April 23rd. No on-site manager ever came on site, the lead guy of the work crew was not an effective communicator. We engage beyond the one time he asked for an extension cord. I called POWER and left a message with Chris Pierson that same day after the crew left to express my dissatisfaction with the roof over the garage. POWER came out to inspect/QA the project at completion (the roof) on April 25th, I believe his name was Zach. We pointed out the concaved roof on the garage. He stated that portion may be a structural issue and Power could not address that. I asked him how much would it cost to replace it? He thought about it for a minute or so, then stated it could be replaced, but it would be “redo” and he quoted us a price of approx. $8900. He proceeded to say that he could knock it down to about $7800 if we added an additional project to replace the house trim. This is when he mentioned that they have company meetings on Tuesdays in the morning and he was sure this project would be discussed. He acknowledged that POWER’s communication could have been better (better details in the project notes). We waited few days thinking that someone from POWER would reach out and when that didn’t happen, we called Chris Pierson (the POWER sales guy) on April 28th. During this call, Chris scheduled another QA/follow up appointment for May 9th at 10:00am; he said Dylan, a service manager would come out. On May 9th no one showed up. About 10:20am, we called POWER only to find out that we did not have an appointment for that day. We were not the appointment list. We then rescheduled for 10am the next day, not even 10 minutes later POWER called back to inform us that unfortunately they were not going to be able to make it because of some staff meeting. I recall asking “is the meeting all day”. That’s when we were told that the next available date was June 16th; feeling like we had no choice we accepted the June 16th date at 6pm to allow both of us to be present for the meeting. Upset and feeling like we were about to get the runaround, we placed a call to GreenSky (financing team) to inform them of the matter since loan was activated and payments would begin soon. After sharing the situation with the GreenSky rep, she took notes, and we submitted a complaint because again we felt like we were about to get the run around. On June 12th, we had a call with the assigned GreenSky caseworker. He advised that we should continue to try and resolve the matter with POWER. On June 16th around 1:50pm, I received an apologetic call from Terry, apologizing for being late, that his prior appointment ran over, he was out in the sticks and phone reception was not all that great. I mentioned that our appointment wasn’t until 6pm as so my husband could be home. I was told that I must be mistaken because they don’t make appointments after 6pm, his latest appointment would be around 4:00pm. He said that my husband really didn’t need to present, it would be a quick look and since he was in the area. He asked for a summary of the situation; I gave him the run down. He asked if I could send him a few pictures, which I texted him a few of the garage roof. He said he got the jest of it. He apologized and asked what could they do… we said that we would be open to a knocking something off the price or repairing the area. He said let me call my office. He called us back to say that someone from senior management would be calling us to try and resolve this that evening of June 16th, but still haven’t heard from him or POWER."
