I worked with AJ from the onset, he was SUPER responsive and really went out of his way to make the process easy. The work was started on time, the workers all were fantastic, they made sure the area was protected, they were super polite, and they also went well out of their way to make sure everything was done professionally. AJ's follow up and at every stage through the process was professional and greatly appreciated.

Wish we could give more than 5 stars. We had a complete roof tear off and replacement with new gutters, leaf guards, and 2 roof windows replaced.

We had a great experience working with AJ for both a skylight replacement and a new roof. He was friendly, explained everything, and was honest about what we needed to do now vs. what we could put off for a few months. The roof looks fantastic and they did a very thorough job of cleaning up all of the debris. We will for sure reach out to them again if the need arises, and would definitely recommend them!

I sent an email to Four Brothers at 10p.m. asking for an estimate for two vent pipe gasket replacements and AJ was on my roof at 9a.m. the next day. He finished the job and then walked me around the house advising me on the condition of the roof, pointing out a few popped nails and telling me to keep an eye on them. Excellent service all around and very a very friendly and professional gentlemen. A great contact to have for future needs.
