What an absolute PLEASURE this company was to work with!!! I consider myself to be relatively difficult to please. My expectations are usually not met, and virtually never exceeded. James and Whitney exceeded them in every way! It started with two lengthy home visits by sales representative Cory Little. Prior to the first visit, he obtained drone footage of our roof so we could see exactly what he was talking about. He was honest, thorough, and exceptionally courteous. He had multiple proposals prepared and explained them all until we were satisfied on our decision. He showed me a photo of who our project manager would be and gave me the manager’s contact information, while letting me know I could reach out to him at any time as well. Enter project manager, Daniel King. Daniel telephoned me to explain how the days of installation would transpire. He was here at 7am as promised to open the job. He was in communication with me throughout the job. He even took the initiative in moving our personal vehicles around as I was responsible for remaining inside with my elderly father who has advanced dementia. His roofing crew was TOP NOTCH. No holds barred, the hardest working crew I have ever watched. Knowing that dad was deeply disturbed by the noises, they finished a two day job in 10 hours! They were roofing in winter, after dark, with headlamps. I gave the crew access to an over the garage apartment to warm up and have coffee. When the crew left, I was expecting to have to mop, wash dishes, and clean a bathroom. NOPE. They left it as tidy as they found it!! Construction workers. I could no more strongly recommend this company!

Siding keeps coming off. Not worth the money I paid. I have had roofing and siding done by this company. The roofing would be five stars. The siding is getting a 1 star because there was no communication that my work date changed. They sent the bill before the job was done. The dumpster and extra equipment was left in my yard for 5 days. Now the siding is coming off. Also I had to specifically ask them to fix the rot I saw that they were trying to cover. I can assume from that that if there was other rot it got covered. I had this done month ago. 5 times my siding has fallen off since installation.

I had James and Whitney Co do my roof, vinyl siding and upcoming new rain gutters. I can’t say enough good things about my experience. Dane started the whole project by coming on sight and discussing what my goals were. He made suggestions and answered all my questions. I reached out to him several times before things got going and he was always there for me. The roofing project came first. The team arrived promptly at 7a.m. and removed the old shingles, put new ice and water shield and new shingles, then cleaned everything up and were gone by 11 a.m.! The next project was new vinyl siding. Cedar shakes were 30+ years old and long overdue for replacement. They started on a Monday and by Wednesday mid-day they were finished! The gutters are next. I had posted pics on social media and had a few folks ask if I got a new house! Many thanks to Dane and the project managers for the roofing and vinyl siding projects. Also to their hardworking, dedicated crews. I would highly recommend James and Whitney Co. if you are in need of exterior work.

We are extremely pleased we chose to go with James & Whitney for our siding project. We had several other businesses give us quotes and decided to go with James & Whitney. The salesman was knowledgeable and presented the company well. The project manager Heath and the whole crew did an amazing job with putting the siding on. They took the time to make sure it was done right and that it looks spectacular. We have had many people stop to tell us how great it looks and say they can see how well they did with the siding. Some of the communication could be improved, but as far as the work, workers, and quality, we highly recommend them.

I had my roof replaced on April 14 by James & Whitney Company. To me, my roof replacement job was complex because my roof was a hip roof, joined by another hip roof of a different height, joined by a sunroom roof of a different height to that, with a very low pitch. Both hip roofs were joined seamlessly. Old decking was made up of smaller boards, so new 4x8 sheets of plywood decking were needed throughout to ensure consistent base for new shingles to go onto. The flashing at the base of the brick chimney, as well as the stone chimney, was redone and looks very nice! Cricket was added behind the stone chimney to help disperse water to either side of the chimney. The finished look is breath-taking! The drip edge they used gives crisp, straight lines throughout. Their "attention to detail" is top notch, with special care taken where the sunroom Flintlastic low slope roofing meets the shingled roof. A fascia section highly exposed to moisture was replaced with a PVC fascia, so I never have to worry about sanding and painting that section in the future. From the beginning of the project with Tyler taking the time to go over all my options and recommendations and responding to all my questions, to Brandon ensuring all is running according to plan and including the dumpster pickup that happened the very next day, to the crew working very hard to ensure this project started and finished on the same day, and the cleanup that resulted afterwards. I am extremely happy with the results! This crew is very hard working and they work extremely well together. The few times I looked out my window, there was a flurry of activity every time! When the project was done, special care was taken to rake the area clean of any and all debris, and they used used a wheeled magnet to ensure every last nail got picked up. I highly recommend them!
