Nelson Onderdonk Roofing LLC

Nelson Onderdonk did an amazing job on my roof. I have a 200 year old home. He rebuilt my whole roof. It looks brand new. He was so particular and left the area around the house immaculate each day. I would recommend Nelson to anyone needing a new roof. Outstanding work .

Nelson and his crew did a great job replacing the roof on our home & shed at a reasonable price.
Our roof work took about 3 days and his crew worked from early in the morning until late afternoon.
They took precautions when one of the days presented some rain.
The crew worked independently well and also worked great as a team.
They were friendly, hardworking and respectful of our home and yard.
Nelson was on the job each day supervising and working.
They cared about details and stayed until they were done.
Cleanup was a priority before they left.
Nelson also connected us with a brick mason who rebuilt our chimney.

Our roof looks great and we would certainly recommend Nelson Onderdonk Roofing LLC to others!!

Nelson and his entire crew were friendly, hardworking and courteous. I had to ask them to pause working for an hour twice during the time they were here because I was presenting and recording a webinar, and they readily accommodated my request.

Nelson came out to provide our initial quote and got up on our roof and did some caulking at no charge to help with a small issue we were having until we made a decision about the larger job. This, when he didn't even know if we'd choose him yet for the larger job.

His crew took the time to tidy up after themselves every day, not leaving materials lying around, etc.

Our roof looks and functions great and he was able to connect us with someone to provide new gutters and downspouts as well.

We would definitely recommend Nelson and his crew and are very satisfied with their work. It was a large and complex job and they did an awesome job, plus they are just nice people!

Nelson and his brothers did an amazing job on our 166 yr old house. We had a complete roof replacement. They offered a very competitive price and the work was outstanding. Transformed this old house to a beautiful brand new roof. I highly recommend Nelson.

Nelson and his crew were phenomenal. They installed a brand new roof for me at the beginning of the summer. He went above & beyond fixing a few other issues found when tearing my old roof off. Its hard to find companies who value work as his team does. 10/10 HIGHLY RECOMMEND

Nelson and his crew did an amazing job replacing my roof and gutters. They identified a number of problems and expertly addressed them all. Having replaced a number of roofs over the years, I have never seen such a clean install. Highly recommend!

Nelson and his crew did a very high quality, competitively priced and detail oriented job. They also repaired some serious rot and structural damage that was hiding beneath the surface. The end result is beautiful and you would never know they were here. Very highly recommended.

Nelson and his crew were fantastic! Had been agonizing about a new roof for over a year when I found this company. Nelson made me feel confident in the process without any “hard sell” tactics. He and his crew were professional and courteous. I love my roof ... So glad I found them!

Nelson & Co. really delivered on a fairly complicated roofing job for us at a very fair price. Great communication, friendly crew, ended up doing some gutter work for us also. The very definition of a terrific locally owned family firm. Highly recommended.

Nelson works fast and provides multiple solutions to find the best value, whether it's a new kit or a combo of used items to meet your budget. We called him back for a second job and he remembered that we had a newborn, so he knocked softly on our front door (it's the small things that matter when hiring someone to work on your home). This is a family business that functions with great ethics and kindness. Highly recommend.

Had roof replaced on house and garage. Was nervous having this done as you just never know how something like this will go. It went great. Really precessional and conscientious people that did great work. Would definitely use them again and refer to any of my friends.

Friendly, fast and superior workmanship. Very pleased with our roof replacement. Highly recommended.

Very professional, courteous and communicative . The new roof looks great and their price was very reasonable. Would highly recommend Nelson Onderdonk.

Nelson and his crew were great! Very responsive, great communication, good price, and fabulous work.

Great install and great price!

Our company has worked with Nelson for years and his work is quality.

Kind and courteous...great company
