"I couldn't be more pleased with the outstanding service provided by J. Cwanger. From the very first call regarding a roof leak, their team was professional, responsive, and incredibly helpful. Their initial inspection and diagnosis were thorough, and they provided clear explanations of the necessary repairs. Throughout the process, communication was seamless, even with the added complexity of coordinating with my loan approval. I truly appreciated their patient and understanding approach, as they never pressured me for a sale and consistently kept me informed about scheduling. Once my loan was approved, J. Cwanger's team was on-site within days. The roof replacement was completed in a single day, a testament to their efficiency and skill. During the work, they identified and addressed unforeseen issues with the underlying plywood, demonstrating their commitment to thoroughness and quality. What truly impressed me was their follow-up after a significant rainstorm. The team proactively came to inspect the roof the next morning, ensuring everything was functioning as expected. This level of dedication and customer care is rare and greatly appreciated. J. Cwanger came highly recommended, and I now understand why. Their professionalism, efficiency, and commitment to customer satisfaction are truly exceptional. I wholeheartedly recommend them for any roofing needs."

"I had my roof installed four years ago. They did an excellent job. The workers were pleasant and efficient. I had to call again for a problem with my downspout just the other day. They responded quickly. Again, the workman was very pleasant. I would definitely recommend this company to others!!"

"We had Brian replace our entire roof, including ripping two layers. Brian is always very professional and knowledgeable and the quality of his work is excellent. The job was delayed due to weather and schedule run overs in jobs before ours, but Hope provided us with regular status updates so we knew when to expect them. We used Genovese in the past for repairs and were very happy with the roof replacement.

Christmas Day we had a leak I called and he answered and came out the next day to repair my roof. The owner was professional and polite and made my roof a priority!  We joked about how santa ruined my roof! I was amazed how fast the repair took and how  quick he came out over a holiday. We are on a fixed income and procrastinating to get our roof redone. I definitely called the right company because they made it way more affordable than we anticipated.

"Ivan did an outstanding job on the replacement gutters. It was a one day job and he worked throughout the day. I might add that it was a Saturday. The recent storms has shown that the gutters do not leak. Installed 5and quot; gutters and 3X4 downspouts. I opted not to install the leaf guard system.
I am looking to replace the siding on my house. I would certainly give Ivan a call to give me an estimate when the time comes to do that.
