Mick Lacenski
Had our roof fully replaced by 4 Brothers Contracting and I would recommend their service to anyone needing exterior work done. The entire process was smooth with prompt return of an estimate, to scheduling and prep before the project. The new roof looks great and was completed at a high-level of quality. They even went above and beyond to remedy another small problem unrelated to the roof. Couldn't ask for more from a organization.

4 Brothers was great to work with! I noticed water damage due to leaks in my old roof, and they came out right away to assess it and answer all of my questions. They even fit me into their schedule before more storms came to prevent further water damage, and completed all the work (chimney removal and roof replacement) in one day. I would definitely use 4 brothers again for any roofing projects.

4 Brothers was our contractor for full house hail storm damage repair/replacement. After the storm, we needed to replace the roof, gutters, downspouts, several windows and siding. AJ provided exceptional customer service start to finish; from the first walk around to assess damage, working with the insurance company, and final punch list. The work completed was high quality, the crew were professional, and house looks amazing! I highly recommend using 4 Brothers!

AJ, thank you for the absolutely wonderful experience we had working with you on the roofing, siding and gutter replacement that was done to our home. Your attention to detail, responsiveness, and excellent communication was second to none. You and your crews exceeded our expectations in every aspect of the work performed. As a contractor for home repair you have truly raised the bar for other contractors. You deserve a ten star rating !!!! Again, thank you. Mark Sargent
