One reviewer praises the roofing but says the siding remained unsatisfactory after a second visit and the matter was still unresolved.

Customer Reviews

Emily Bain

I worked with Dane to install gutters on my home and the entire process was simple and completed perfectly. They did such a great job that I referred my father to do the same. We have both been very pleased with the quality of the work. Thank you Dane and James&Whitney!

We had a fantastic experience with this roofing company. They came out promptly, did a thorough inspection and provided a clear, honest quote without any pressure. Michelle , the receptionist, was incredibly kind, professional, and helpful. She made scheduling easy and followed up to be sure we had everything we needed. Great customer service from start to finish. Highly recommend!

James and Whitney does a great job with their work. They have solid teams and will give you a reliable result. Jesse was our project manager and did a great job! There was good communication and all of our concerns were addressed in a timely manner. I used them on a seperate project too. There was a persistent intermittent leak in a single spot that took quite a bit of effort to actually find. They came out multiple times until the job was actually done. Very few contractors would actually have that level of follow through! I would definitely recommend them for exterior work!

James & Whitney recently performed a complete roofing and siding job on our house. The roofing was exemplary. The siding not so much. We decided to go with the best siding (everlast) and we were sold on the fact that the work performed would be completed by qualified professionals. To our surprise the final result was less than satisfactory. The project manager came out a second time with a "qualified " crew and still the job was unsatisfactory. We are waiting for this matter to be resolved. Would I recommend this siding to others???? Not unless you know the crew putting it up is highly trained and knowledgeable in what they are doing. We are out 60K+ for the siding alone. I am providing pictures of the quality of work that we were left with. Update 11/14/25: Added more photos of the lingering concerns. Quality manager said that they are done dealing with us and we need to understand that a house shifts which will cause this. They are going to color match caulk the siding to appease us. Please take warning that it is not a true statement that they have a 5 year workmanship garuntee on work performed. The customer service from the quality manager is less than satisfactory, the everlast product is probably nice when the siding company puts it up correctly.

Outstanding customer service and professionalism! In August 2023 James & Whitney replaced the roof and did some gutter repair on my circa 1783 house. I was very pleased - their bid was significantly less than a well-regarded competitor, salesman Shayne was helpful and courteous, and supervisor Brandon & his crew executed the job professionally, quickly, and with excellent results. Recently I noticed that one of my gutters wasn’t properly placed, but I couldn’t recall if that section had been within the scope of the repair work so I reached out to the James & Whitney office. The woman who spoke with me responded courteously and said she would have someone follow up. Brandon called me promptly and recalled the problem from 2 years ago in detail, reminding me that repairing that section had not been part of my contract and that he had discussed it with me at the time. He was correct. Nonetheless he offered to send his gutter guys to take a look when available. Imagine my surprise when Geoffrey and crew pulled into my driveway later that afternoon with their fully equipped truck and cheerfully repaired that section of gutter on the spot at no charge to me! I truly am thrilled to have received such genuinely 5-star customer service from the good folks at James & Whitney Co. Highly recommend!
