Reviews

What customers say

Customers praise responsive office communication, accommodating service and professional coordination. One customer said a roof was completed within a few hours; another praised the exact match the team found for wind-damaged fascia and soffit. One customer reported recurring leaks at a worked-on section of a flat roof despite at least two patch attempts, and said another patch would be chargeable after the one-year warranty expired; another described a technician arriving before the rescheduled day and workers arriving ahead of the appointment window.

My landlord scheduled a roofing repair appointment with this company for Friday, December 5, 2025, with an appointment window of 8:00–9:00 a.m. At 9:30 a.m., the company contacted my landlord by email—not by phone—to reschedule due to the snow, which was completely understandable. The new appointment was set for Tuesday, December 9, 2025, between 1:00–2:00 p.m. However, the company unexpectedly arrived on Monday, December 8, 2025, at approximately 1:06 p.m. I answered through the Ring camera and spoke with the technician, who appeared unaware of the updated appointment date and time. He asked if he could perform the work at that moment, and I informed him that I was not home. He stated that he would return the following day during the scheduled appointment window. At this point, I began to question the company’s professionalism and anticipated further scheduling issues. As expected, on Tuesday, December 9, 2025, the workers arrived again at 11:44 a.m.—well outside the 1:00–2:00 p.m. appointment window. I spoke with the technician and reminded him of the scheduled time, explaining that I was still at work. He stated that he would wait. I arrived home at 12:45 p.m., and he returned to my door at 1:11 p.m. Upon entering the condo, he inspected the ceiling where the hole was located for 2 seconds and informed me that he would begin working on the exterior roof. I asked whether he would be repairing the interior afterward, and he stated that I would need to hire someone else to complete that portion of the work. I immediately notified my landlord, who was also unaware and confused as to why the company requested interior access if they had no intention of repairing the ceiling. The workers were on the roof for less than an hour before leaving. I looked out the window and noticed that the company vehicle had already departed. Neither of the technicians knocked on my door to provide an update, so I have no information regarding the status of the repair, whether the work was completed, or whether it was successful. The level of unprofessionalism demonstrated by this company is unlike anything I have previously experienced.

I had a great experience working with the 412 Team. I got a great overview of the services before I had to make any major decisions. I'd also like to share that this was not a "sales pitchy" interaction, I felt comfortable contacting them to get scheduled at my pace and didn't feel backed into a corner to make a decision on the spot, which is not my usual routine with contractors. Once I was scheduled, the guys were here bright and earlier and finished my roof with a few hours. The administrative team was also incredibly responsive and efficient. Overall this is the best experience that i've had with a large home project in a very long time and I am incredibly thankful. Great Work Team!

I worked with this company because of the good reviews online. Unfortunately, it was a mistake. The intitial meeting was fine. The salesman seemed knowledgeable. I had the company work on one side of the roof to slope it more because water was puddling and not draining from my flat roof. Unfortunately, within 1 year of the completed work, we started seeing signs of a roof leak. The leak was coming from the side of the roof they worked on. They had to patch and repair at least 2 times and we are still experiencing leaks. My recent contact with them was disappointing. They were going to charge me several hundred dollars to patch up again because the 1 year warranty had passed. It's about 3 years since they did the roof. I feel a roof shouldn't fail within a year and it shouldn't be patched up every few months. I have learned an expensive lesson. The initial work cost me over $8K. Please save yourself the hassle, the time, and the money. I am going with a different company this time to resolve this leak issue. There are reputable companies out there that guarantee their quality of work for more than 1 year. The attached pictures are the current state of my children's bedroom. Their ceiling is right below their failed roof work.

Paul and his team at Four Twelve did an excellent job replacing our Facia and Soffit that was damaged by high winds. They were quick with a quote and the only company that was able to find an exact match of our materials. They coordinated everything including a lift rental and were on time and very professional throughout the entire process. I highly recommend them!

Four Twelve was SO accommodating and all around wonderful to work with. We had damage to our house after a storm, and after contacting SEVERAL contractors, Four Twelve was 1000% the way to go. The blue house with the red door in the photos is my house (before the storm), and the green with the black door is my house after Four Twelve got done with everything! My husband and I LOVE our house, and recommend Four Twelve to anyone who needs anything done to their house, big or small. For reference, we got new roof, siding, shutters, gutters/downspout, chimney, fascia, some electrical work done, and painting.
