Customer Reviews
"We want to send a big thank you to Joe and SJ Roofing for transforming our 1950's shore house in Ventnor. From our first meeting, Joe listened to our wishes and offered sensible ideas to enhance our vision. To say SJ Roofing exceeded our expectations is an understatement. We communicated that finish work and detail were a priority to us, and the finished project shines with those touches. Meticulous dedication to detail aptly describes the goal of the business and the various teams involved in the project. We want to especially thank the team involved in the windows, siding, and the new entrances. They were on site for most of the 14 days, and their dedication and hard work could not be overly stressed. Finally, things happen in life for a reason. We feel blessed that our initial call to Marcus for a leak at the house led to the subsequent call to Joe about this project. SJ Roofing came through for us, and we urge you to contact them for any of your exterior home projects."
"SJ roofing is very professional and they do great work for a fair price. They did my roof on my shed, my gutters, replaced my sliding glass door, my bathroom window, and replaced my front deck. I highly recommend this company for all your needs!"
"I recently had some work done on my house with SJ Roofing. Joe was great. Very professional, and everything that was agreed to was delivered on time. I would definitely recommend SJ Roofing if anyone needs roof work done. Thank you SJ Roofing!"
