This is my second time working with John Oros & Berg, the first time was 6 yrs ago for my roof, gutters soffit, & they did an excellent job. This time was to install new windows & a new window opening. John is truly a pleasure to work with, honest, professional shoots straight & very communicative. His guys do an excellent quality job & had the best prices for the excellent quality product & services they offer. I feel full confidence to refer them to friends & family & suggest if your looking for roofing or windows don’t look anywhere else!

Nick Peters was very helpful and knowledgeable. He took care of communications with my insurance company on a hail damage claim. I would recommend Berg to all my friends and family. They did a great job.

Nick was our sales person. He was professional and delivered as promised. It took a little more than a day and a half and he checked in both days to make sure things were progressing and to address any concerns I might have. The crew was also professional and did a great job. You could see they were experienced, paid attention to detail, and took pride in their work.

Wonderful experience with Berg Roofing. Our roof was replaced approximately one month ago with no problems so far. We expect many trouble-free years from our new roof. I researched many companies and Berg was clearly the company to work with. John was terrific and answered all my questions honestly. The price was extremely competitive. I would recommend this company to anyone who needs their roof replaced – in fact when it comes time to do the windows, I will give John at Berg a call based on the experience I just had. Joel A.

Berg Roofing successfully completed a complete tear off our existing layers of roof and installed a completely new roofing system and skylights using Certainteed Landmark PRO Architectural high-definition shingles. John Oros, Project Manager, was terrific and very easy to work with. Additionally, the on-site foreman and crews were so hard working and professional! All aspects of the job from start to finish, exceeded my expectations!!!

I couldn’t have asked for a better experience than the one I had with Berg. John Oros was fabulous to work with and was extremely courteous and professional. I obtained ten quotes for a windows replacement, and John gave me the best price by far. He was not a “sale-see” but instead explained what my options were. No pressure sales tactics were used, which I really appreciate. John was great about emailing me throughout the process on a timely basis and immediately responded to my questions, no matter what time of the day. The installation crew was very professional, arriving exactly on time and quickly replaced the windows. They even fixed one of the broken blinds in the process. I would recommend Berg to anyone and have only wonderful things to say about this company. Thank you, everyone!

They replaced our roof in only 2 days; our siding took a little longer because of the weather. We had one little problem that they corrected immediately. The crews were respectful and friendly, and hard workers. We would recommend Berg for roofing and siding. The price was so reasonable. John Oros was our contact and project manager and kept us apprised of the timing of each step, as well as follow-up after and during each stage. He was great, and we are very pleased!

Over the years, I’ve had Berg complete three jobs at my home. They’ve consistently completed high quality work and communicate well before/during/and after the work is completed. John Oros does a great job of making himself available and working to meet homeowner needs, educating, and supporting the decision-making process along the way.
