#1 Roofing Company in Cambridge

I used NexGen Exteriors in 2025. I wanted to get information on roofing & siding but I didn’t know much about it all. Jeremy came to give me an estimate on the work that could be done and he answered all of my questions thoroughly and in a very kind, patient manner. Once the work began the crew worked very hard and efficiently to get the job done. During the process, yes my yard looked like a disaster with all the materials and tools needed spread out everywhere. With that said, they did a fantastic job cleaning up afterwards to my satisfaction and to ensure there was nothing left behind that could harm my dogs. Everyone I talked to within this business (I’m sorry I don’t remember all their names) was very kind, friendly, professional and made me feel confident I made the right choice with NexGen. Thank you to all that made it possible, my house looks fantastic now!!! Kathy Lund

After numerous failed attempts to find someone to repair/replace two large skylights we found NexGen / Chris Scharmer- what an amazing guy and company ! From day one Chris was on top of things and always available with explanations n answers 👍👍 a very kind , thoughtful, professional person to work with. Bob Glick was also very helpful in lining up the installation team 👍 After a minor delay the 2 skylights were removed and replaced by a team of talented n professional guys 👍 and no more battery operated shades - we have solar powered shades that are awesome! Many thanks again Chris and Nex Gen 😊 We will use them again without hesitation!! Cathy & Ed Gould

The workmanship is top-notch— our house looks like a brand new house! From start to finish Nick and Cody were professional and knowledgeable and made the process so simple and hassle free for me. Would highly recommend using Nick and Cody to family and friends!

I had my roof installed by NexGen and the whole experience was great. Cody was professional, knowledgeable, and always straightforward with me. He kept me updated, explained everything clearly, and made sure the project stayed on track. The crew did excellent work and cleaned up perfectly. You can tell NexGen really cares about their customers. Highly recommend working with them—and ask for Cody!

Aaron was our sales person . He was energetic and guided us through the process effortlessly. But it wasn’t just Aaron it was the entire experience with Next Gen and their process. The communication from the install team was fabulous. And when the roof was done, you did not even know they were there . My husband is never wanting to do anything to the house because of the intrusion to our daily life . Aaron and the entire team made it a pleasure . And I got a roof color I liked !

Thanks Travis and NG for helping us transform the exterior of our home, we love it! Travis and their team really helped with navigating the insurance side of things, after experiencing hail damage. Aug 1,2025 Today Tim & Nick finished the install of our 10 windows. Can’t say enough about these guys. We had some big challenges & they both powered thru them with ease and professionalism. They left things so clean (maybe even cleaner than they found it😄). Also want to mention how beautiful Walsh windows are (made in MN). A big thank you to all the NexGen employees for helping us thru this stressful yet rewarding process. I can’t hank you enough for taking such good care of us along with so many others in our community, many of which are my personal clients.

Aaron Bethke was professional and helped deal with my insurance Co! love new roof! John Tessendorf

Aaron worked with me getting my roof replaced. He went up and saw what other people didn't and helped me get the ball rolling on getting my roof replaced. My insurance only wanted to cover half my roof... but after a little over a year Aaron battled with the insurance company and got me my full roof replaced! I appreciate Aaron for all the effort he put in! I would recommend Aaron to anyone looking to get work done at their house! Thanks bro!!

Professional, courteous service, very knowledgeable about the insurance claim process… Aaron and company did a great job!

Nexgen was incredible from start to finish. We had a bad tornado come through and the hail damaged our roof bad. We had people knocking on our door non stop for days trying to get our business. All of them gave us the same pitch of just let us take a look and then sign this contract and we can get you taken care of. None of those companies explained anything of how the process worked or what we were going to pay or even what we were signing. Then Amanda and Aaron from Nexgen showed up. They saw the chalk marks on our roof left from the nsurance adjuster and they just simply asked if there was anything they could do to help or if we had already been taken care of. then they explained their product. We set up a time to meet and go over things. During that time my mom passed away and I had to leave town for a couple weeks. Amanda swung by our house and dropped off a card and candy for my kids because they had just lost their grandma. (They didn’t even have my business yet) they just gave a crap. Well let’s move forward to building day. They showed up on time with everything g needed to complete the job. They tore my roof off and found that the sheathing was toast. It had 6” gaps between boards and was just not ok. They took tons of pictures of everything and They fought and got the majority of that extra expense covered by my insurance. The roof is beautiful. The crew they had at my house was incredibly professional and even laughed with my kids while they were cleaning up. I was aware of everything every step of the way but it took zero effort on my part for any planning or anything with my insurance. I would recommend these guys to anyone needing any type of work done. Hands down a great experience in a crappy unexpected Time. Thanks Aaron, Amanda and team for everything you have done for my family. Happy to call you guys friends now.
