We had a damaged roof and siding from high winds. J Cwanger was fabulous! Jeff explained everything and helped us choose the right siding and color roof. His workers were courteous and fast. Cleanup was perfect. Everything was exactly how he described. I would highly recommend this company without hesitation.

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.

J Cwanger had a very competitive price and performed the entire job using quality GAF materials such that the roof has a 50 year warranty. About 2 years after installation, the roof leaked and they came immediately to repair the issue. Unfortunately, the repair required was not the immediate patch job. When it still leaked, they came back and did an extensive fix to the whole area around the leak and it has not leaked again. It's good to work with a company that stands behind its work for years to come.

I sent this company an email asking for a quote to repair a serious leak round my chimney. They requested a phone call, which I was happy to do to describe the problem. The next day, they came out to diagnose the issue (bad flashing as expected) provide a quote. Upon acceptance of the quote, which included completely redoing the previous bad job, the provided the services in two days. A bill arrived the following week. I couldn't say enough good things about this entire transaction. The price was fair and all aspects of this quality repair were professional. I even asked them to give me a review of my roof, as it's been on the house since I moved in. There was no up-sell attempt at all, just an honest assessment. I will definitely give them a call when a new roof is needed.

A good, solid roof from a good solid company! Cwanger has been an institution in the Cherry Hill area for generations. The company is being capably guided into the 21st century by Jeff Grimley, an associate and protege of the founding family. This is the second roof I have had done by this company, and I believe the third this home has had from Cwanger over the course of 60 years. (The former roof was due for replacement due to the age and appearance of the shingles, however it never leaked or needed repair--a testament to why I am loyal to this company.). Mr. Grimley is the only roofer I dealt with who had a confident, no-nonsense approach to our roofing needs. He guided us away from certain, more expensive options that we did not need, and towards the right roofing solutions for both longevity and proper roof ventilation. Cwangers was not the lowest estimate, but overall was a fair-market price for a company with a fine record and quality workmanship. The work crew also seemed very professional and satisfied in their endeavors. [I intentionally write this review several months after installation. The roof has come through several storms, including a recent wind storm with no problems, whatsoever.]

I left a voicemail when I first called and received a prompt response and scheduled service at a time convenient for me a few days later. They showed up exactly on time, listened to my concerns, and resolved the issue very quickly. I had a leak in my roof that they repaired easily that day. I haven not seen any issues while it rained since then.

 We are extremely pleased with the work that was done.  The shutters were difficult because they needed to match the 30 year old shutters that were on the rest of the house. Jeff ordered unfinished shutters and had paint mixed to match the color.  They turned out perfect! Their employees knew what they were doing and completed the work in a timely manner.  They also cleaned up the work areas work (both inside and outside the house) before they left

We have used J.Cwanger many times in the past.  They had replaced our roof, gutters, downspouts and soffits many years ago.  We also have them clean our gutters every year.

We have never been disappointed with their work and highly recommend this company.

Although price was $500 more than the nearest competitor, I believe the warranty was a little better than another roofing material's warranty. Also, Cwanger's estimator pointed out things I should be aware of with roofing jobs, including being sure that any roofer I selected would actually file the necessary paperwork to insure warranty was in place (I had been upset because my prior roof was only approximately 12 or 13 year old on a rehab of the house done by prior owner). Cwanger started and completed job as stated after it was scheduled. Cwanger was careful about foundation plants and perrenials, cleaned up after finished. Although I was not present on their cleanup of marks on my siding, they came back to remove a few missed spots when I was able to be present to point them out. I was very happy with their professionalism and have recommended Cwanger to others.

Requested an estimate for new Roofing, Gutters, & Siding via Angies List Site. Provider responded saying that they would take a look at the property and get back to me. Provider never responded.

Provider did call me and send estimate.  Thanks!

Everything went very well. The worker showed up on time, and spent at least four very thorough hours on the job, and cleaned up and took away all the resulting debris. Terrific! We will definitely be contacting the J. Cwanger Inc. company next year when we replace the roof shingles and gutters.

It was fantastic.  They were great people who did great job.  They were on time and cleaned up very well.  I had an issue with a gutter that was leaking and they came right out.  There were no issues at all.  They were very professional.  The owner and the guy was great.

Jeff Grimley (main guy under Cwanger) was most trustworthy roof contractor I dealt with.  He reminded me of Mike Holmes from HGTV - he really looked into my problem and I found him to be the most reliable and upfront compared to other contractors.  Was on-site nearly every day.  Crew was professional and reliable.  Crew went above and beyond to make sure that job was done right.  Thanks to Jeff G. and crew for their hard work.

He gave us the best price. We did get estimates from a different company. From the day I talked to him, he did it right away. Within two days, the job was done. The patio was leaking but I haven't seen an issue. The job was done well. It was quick. I don't have a leak. I would use him again.

The crew was very punctual, professional and most of all 15 minutes early for  the job. They were very responsive to any questions or concerns I had about the placement of the vents. They got right to work and was done within 30-45 minutes and cleaned up after themselves. I will definitely be using this company again in the future.
