Berg did a wonderful job on my windows, so I recommended them to my mom. My mom owns an older Chicago two-flat, but Berg was up to the task and did outstanding on the window installation. Nick was very super nice and easy to work with. We were also impressed by the professionalism and skill of the window installers. I would highly recommend Berg.

Purchasing a roof can be a very nerve racking process. The entire experience with Berg was very professional from quote to final build. You can count on timely communication and thorough answers to all your questions. The final product exceeded my expectations for a very reasonable price. Highly recommended!!!!



Worked with Nick to replace our roof. His communication was excellent and prompt. Berg’s quote was extremely competitive and the work was completed on schedule, done well and the cleanup was great. They required no money down and you only paid when the job was completed to your satisfaction. If you’re having a roof replaced you need to include Berg in your process.

We had a great experience! Berg did our roof. Tear off and new shingles. They were able to move us up in the schedule due to a cancellation. The workers started on time and were careful doing the tear off. The debris was moved over to the dump trailer from all sides of the house. Not much fell off away from the trailer. One of the workers kept the grounds picked up the whole day. We only found 6 nails they didn’t pick up. The shingle installation went smoothly and was completed in one day. Very happy with the final result.

John did a great job looking at all of our windows, answered all questions thoroughly, he was quick to respond to messages and kept us updated on manufacturing and installation progress. John really helped make the process seamless and easy! We are very happy with our new windows and plan to use Berg for future home improvements. I highly recommend working with John.

John & team @ Berg roofing are quick to reply, personable and they provide quality value. I would use them again for any roofing needs/concerns.

Eddy M.


I contracted Berg to re-side my garage and repair some rotting fascia boards. Nick was very responsive throughout the entire process, which because of our issues with another contractor ended up taking more than six months.

The work was done well, the crew finished up quickly, and the price was very reasonable. My wife and I are very pleased and we would use Berg again.

I highly recommend Berg for your roofing needs. They are one of the few trades we’ve hired over the years that are ultra professional and go above and beyond. Here’s a quick summary of our problem and solution.

We asked Berg (and Chris, our manager/point of contact) to delete and move few plumbing vent stacks and add bathroom fan exhausts. They were competitive with a few other firms and were willing to take on a smaller job (aka not a full roof replacement) since the winter season was slow.

The job was quick, well done and the team cleaned up after themselves. We ended up having to replace an entire flat roof portion originally thought to be shingle (but undetectable from lower angles). This was an additional cost but Berg still ate some of it to stay on schedule and some other unmentioned reasons.

The key part in all of this was John’s proactivity in communicating everything from proposal to wrapping up. If you’ve had contractors ghost you in the last few years, you know why this is important. All in all we had our expectations understood and met. I’d hire them again for future roofing needs!

I just had Berg install a new roof and gutters on my home. From the beginning, Nick was very friendly, professional, and extremely responsive. He made the whole thing a lot less stressful than it could have been. They even fixed a couple of things that technically weren’t part of the roof and gutters. My house looks great! I am so happy with the job they did! I would definitely recommend Berg!



I’ve had Berg replace my roof in 2019 and my windows earlier this year. Always a great experience working with Nick and his team. Great quality and craftsmanship. Highly recommend!

Parvinder B.


I would recommend Nick and his team for any roofing needs. Their professionalism, top-notch craftsmanship, and commitment to customer satisfaction are truly second to none. I am beyond thrilled with my new roof and the overall experience.

Carol S.


We worked with John to have our windows and siding replaced on our home. It was the best customer service experience we have ever had. John was in constant contact with us throughout the project to ensure we had no unanswered questions or issues. His crew was professional and efficient. In addition to quality work, they also did an excellent job of cleanup, during, and at the completion of the project. We would highly recommend Berg Home Improvements for their exceptional quality and competitive pricing. The added bonus is having John there to help guide you every step of the way.

M. McCarthy


John was friendly and informative. He was prompt in returning calls and answering my questions. Roof and gutters look great!!

Gary B.

Due to the supply chain shortage, it took a long time for materials to get in but once they were in they got on it and knocked it out. They never hopped jobs and showed up at my job every day until it was complete. They had a clear and organized plan to efficiently do the job and it went about as well as this big of a job could go. All new doors, windows, siding, facia, soffit, gutters….Had to improvise and get creative in a few areas but they figured it out. Very happy with the results and have already recommended them to others.

Kevin S.

The pricing couldn’t be beat, extremely helpful and attentive to what needed to be done. John was upfront and honest. Would highly recommend them to anyone who would ask.

Annamarie W.

Professional and prompt. All the laborers are courteous and easy to work with. Upon completion of the job, the area was cleaned. No debris was left behind. The completed job is beautiful!
I highly recommend this company and will use them again!!

Karla F.

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!

Michael L.

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.

Andrew B.

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.

Kenneth M.

Berg Roofing is the most PROFESSIONAL Company I have ever dealt with. Tom is the man, truly amazing, courtesy of your time, and very professional. I would highly and only recommend Berg Roofing for ALL your exterior needs for your house. They will not disappoint you, but ONLY IMPRESS YOU. They go above and beyond ALL customers’ expectations. I cannot say enough positive words about Berg Roofing and especially Tom and his expertise. Thank you for ALL your help, you have a customer for life and ALL my referrals.

Ilja W.

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. Wolk Bolingbrook, IL

Kristen L.

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!!!

Suzan L.

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!

Brooke M.

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!

Elizabeth H.

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.

Brian S.

Nick came to the house for an estimate, and we had a deal within the hour. Communication was open and easy, the job itself was done quickly and effectively while we were at work and looks incredible. They even fixed a drainage issue from previous owners that we did not discuss, which was a nice surprise. Recommend this company 100%.

Nedim P.

I had a very pleasant experience working w/ Berg Roofing. Their quote came in significantly lower than anyone else that I had come out to my house. The job the crew did was phenomenal, even when the weather was not. They left my property in great shape as far as cleanliness is concerned. John Oros was detail-oriented and went out of his way to check up on me as the project kept getting postponed due to climate weather.

Jim P.

John O. was a fantastic project Manager. His responsiveness was outstanding! His crew (Cesar and co.) did a high-quality job with our siding. Andrew and his crew also did an excellent job on the install of our new windows. They cleaned up at the end of each day which was a big plus. Overall, we are extremely happy with their work and the siding and windows installed.

T Dillon

Berg is awesome! Great communication, fantastic work, and the finished product is incredible! Thank you so much!

Melodi L.

We just got our roof done by Berg, and we are so glad we chose them! Our initial meeting for the estimate was great. The representative was on time, great at explaining everything, and gave us a very fair estimate. When it came to scheduling, Berg’s communication was professional and timely. They finished our roof in one day and communicated with us throughout the project as needed. They cleaned up well, and the roof looks great! We couldn’t be happier! We’ve worked with other companies in the past, and we highly recommend Berg.

Trish A.

Worked with Berg for a full roof replacement, 3 unique skylight replacements, gutters, siding, & trim work. The company rep John was wonderful to work with. He made everything very simple, clear, & he stayed on top of everything, which made the whole experience for me very pleasant. Their teams did great work & good cleanup as well. I would work with John again & recommend that you do too.

Jessie L.

John and the team were very professional, responsive, fair, and punctual. We are very happy with the fantastic job they did on siding our house and garage. They paid attention to details and were very diligent about clean-up as well. I highly recommend Berg Roofing and Home Improvements.

Michelle M.

We cannot say enough amazing things about Berg Home Improvements. From our initial meeting for quotes with John to our final day of completion, we are blown away by the amazing service every step of the way. Working with Berg was incomparable to the two other companies we spoke with, and they made our decision very easy! Their on-the-spot quote was more affordable than we anticipated, we were not “sold” anything but rather given information only on what we were looking to complete, they were helpful in doing what it took to make the project work for us, the work done was always timely and clean, they respected social distancing during the pandemic, communicated throughout the entire process, and overall just satisfied us as customers on all fronts. We live on a busy street and happily have left the sign in our yard and pass out business cards to neighbors because we are that confident in what their company offers. Thank you to the whole team at Berg! And special thanks to John who worked alongside us from day one to completion day.


Berg Roofing has done two roofs for me at two different homes, and both were done exceptionally well. From deciding on the shingles to installation, their service is top-notch. They even had someone come out to meet with our insurance appraiser to help assess hail damage. The crew worked exceptionally fast…I have a huge roof with a steep pitch and lots of angles, so the fact that they were done in a day and a half is crazy. They are trustworthy, and I highly recommend them!

Meg B.

From the presentation of options for siding and windows, including ideas on how to do certain components in an affordable way, to the installation, Berg Home Improvements was professional, followed through, and answered any questions we had within minutes of an email or text. They removed my shutters so I could spray paint them and then replaced them for us at the end at no additional charge. The siding crew worked hard – from 7 am until 7 pm for 4 days. We did pick up a few nails here and there, but for the most part, the yard was left in great shape.

Deonna J

Great experience with a roof replacement. John was punctual for appointments and communicated everything, didn’t have to call him for updates. The crew was professional minding our landscaping and did an amazing job cleaning up seeing the scope of the mess from the project. Pricing was extremely competitive, highly recommend it.

Scott S

It was a smaller job, re-roof a garage, install gutters and soffit and facia. I had contacted 3 different contractors, and Berg came in with the best price. Our contact was Nick, and he was the other reason we went with Berg. Low pressure and informative with any questions we had. An asset to the company. As for the work, all three crews were excellent- they were the real stars. Excellent craftsmanship, friendly and you never would have known anyone was there- the cleanup was so good. Highly recommend and would use them again.

Mark F.

We were put in touch with John Oros as we needed to replace our entire roof. From the start, John was professional, very responsive, and helped guide us through the process. I appreciated that John kept us in the loop throughout the process both regarding timing and during the work itself. The team doing the job was also very professional, punctual, and fast! We are not only happy with how the roof looks but can’t say enough in terms of what a pleasure it was working with this company. I would highly recommend Berg for any of your roofing needs and would encourage you to ask for John. Overall a great experience.

Luis D.

I hired Berg for vinyl siding. They did a great job on the installation and have very experienced installers. John Oros from Berg was very responsive and great to work with. He truly understood and went above and beyond to meet all my needs!

Diane S.

Installed 7 windows for me. Installation guys very respectful of my home and came with masks. Windows look great! Purchasing 7 more.

Christina B

We used Berg Home Improvements for our roof, siding, and windows in May of 2021. We were blown away by not only the quality of their work but their professionalism and customer service as well. From the initial consultations, John was patient and knowledgeable, and the pricing and timeline for our projects were reasonable. Each of the crews for the roof, windows, and siding were always punctual, courteous, and extremely hardworking. Any time we had questions, we were able to promptly speak with a crew member or John. We were prepared for the projects to take longer than promised or for issues to come up, but none of that happened, and everything went incredibly smoothly. Berg exceeded all our expectations. It is so rare to find a company that meets every deadline and is priced, with quality work and customer service from top to bottom. We are so thankful to have worked with them and would recommend them to anyone in need of their services.

Anne S

We had Berg Construction install new vinyl siding on our home. John was professional, knowledgeable, and responsive to everything. They came as scheduled and completed the work in 2 days. The clean-up was awesome. We had many estimates and had researched what we wanted. Berg impressed us with his recommendations and was the best price. We were 110% satisfied with the work and siding product. Highly recommend Berg Home Improvements.

Darlene S

For over a year, we searched for a company that we felt comfortable installing new windows on our home. Finally, we called Berg Home Improvements, and a wonderful salesman named Nick came out to give us a quote and to explain in detail about the windows we would be getting and the time frame that it would take to install them. The installation crew, Andrew, and his partner arrived right on time and were also a pleasure to deal with. They were extremely professional and installed the windows in no time with minimal disruption in the house. They cleaned up thoroughly and walked us through how everything works with the new windows. We couldn’t be happier with the craftsmanship of the installation and the quality of the windows. Andrew even was kind enough to fix a small gap in our gutters where birds were getting in and out. All in all, it was a wonderful experience, and we highly recommend them; and we look forward to having more windows installed soon!

Update: We had Berg out again the following year to install more windows. As before, Nick was a pleasure to work with and offered us competitive prices on high-quality double pane windows. This time Brent came out to install the windows. He did a wonderful job and really took the time and effort to get the finer details, such as capping the exterior trim and caulking perfectly. Again we highly recommend them if you want great windows installed with pride and care at an affordable price!

Leslie Vanco

Berg Home Improvements recently installed our windows and they did a great job. The price and quality were amazing! Work was completed quickly once windows were received. We would definitely use them again for other services!

Jenny McNamara

With the stresses of a leaky kitchen skylight, John Oros came at the height of the pandemic to provide a thorough estimate. I never felt rushed when I asked him a gazillion questions (my husband was quite impressed) I did my research. Berg Roofing wasn’t the cheapest bid, but I had a feeling we’d be taken care of with this project in their hands. Berg and John did just that throughout the project (including new gutters a few months later. John far exceeded my expectations – I’d refer him and Berg Roofing hands down. Thank you.

Roman Leung

Bob is such an honest, knowledgeable, patient and professional. There is no better contractor I have ever come across. He is like an angel from heaven helping me out to resolve my roof issue. Will definitely refer to anybody who has roofing and all exterior housing needs.

Lily Tsai

I would like to thank Nick and his team of contractors who helped me fix up a home I’m remodeling in Villa Park. They did an amazing job with the new garage roof, garage soffit/gutters and new gutters and soffits for the home. I would definitely recommend and use again in the future. Thanks!

Tracy L., Glen Ellyn

I had a very positive experience with Berg Roofing. John Oros provided the most affordable roofing estimate. He was straightforward and dependable throughout the process. The crew worked quickly but effectively. They did a great job cleaning up after the project was complete. We would choose Berg again in the future and highly recommend this company to others.

Nancy W., Naperville

Berg Roofing was GREAT!! The workers are very neat and clean. They were very careful not to damage your yard. The windows and patio door they installed are high quality. I’m looking forward to winter knowing I will No Longer have drafts coming in. We would HIGHLY recommend Berg Roofing!!

Cathleen N., Glendale Heights

Berg was recommended by a friend and after receiving a few estimates I went with Berg. They did not disappoint. Nick was very professional and no pressure. Explained everything and took the time to answer all my questions. They completed the roof in a day and gutters the next. I am very happy with the work and the price.

Tommy D., Lombard

Berg is awesome! Great communication, fantastic work, and the finished product is incredible! Thank you so much!

Paul P., Naperville

Highly recommend! We had a complete tear off, replaced a skylight, added a solar tube and ridge vent. They were fast, clean, professional and had great communication along the way. We will hire them again for future projects.

Bill and Donna Waller

Very impressed with this company. They removed two layers from our roof and replaced it with a new one in three days. Very professional, and very neat. Not one piece of debris or nail left. Now we are calling to have them look at our siding. Highly recommend this family owned company.

Sarah T. Willowbrook, IL

Berg Home Improvements did my siding, fascia, soffit and gutters in fall 2011. They did a wonderful job. I couldn’t believe how fast and clean the workers were. The project took just three days! Everything had turned out just as my salesperson said. It was nice to work with a family business that did exactly what they said they would do! I would and have highly recommended Berg to anybody looking for a contractor. Thanks for a job well done!

Jennifer Downers Grove, IL

I am glad that I found Berg. I had replaced my roof eight years ago and I had used the cheapest priced contractor. What a mistake! From day one I had problems with my roof. The leaks never stopped. The company I used tried a few times to fix them but never did. Finally, I found Berg, they came in and fixed the leaks and I have had a dry roof ever since! Thanks, Berg for all your help.

Kim S. Naperville, IL

I did my research because this is a large purchase for me and I didn’t want to make a mistake. I had gotten a number of estimates. Berg by far was the best company I interviewed. The sales rep did an incredible job explaining exactly what they were going to, the products they used and why. They also said they wouldn’t be the lowest priced contractor but would give me a 10 job for a 5 price. I was glad they were in the BBB. They gave me references and that they were a certified contractor with Certainteed and could offer me an extended warranty that the other guys couldn’t. The job turned out great and I couldn’t be happier with my new roof.

George G. Hinsdale, IL

I had been recommended to Berg Home Improvements by a fellow work colleague. My friend had stated that they do roofs in one day. They were extremely clean and really treat your house as if it was there’s. Boy that was understated, they far exceeded my expectations and I am actually a very picky person. I had them replace my roof and I was so happy that I had them do my siding, windows, gutters and fascia and soffit. It was really nice dealing with only one company for all of my exterior remodelings. Thank you Berg Home Improvements for a job well done! I would highly recommend Berg to anybody, you can’t go wrong!

Greg W. Naperville, IL

I had used Berg Home Improvements for my new roof a few years ago. They were fantastic and they did the job in one day. I had left for work in the morning and the job was done when I got home. It was almost as if they were never there. The cleanup was great. When it came time to replace my siding, windows, fascia and soffit and gutters, I knew I had to give Berg a call. I am glad I did. They only use the best products and they had a very competitive price. They came in and did a great job. The crew was easy to work with and they very accommodating. This was a large project and changed the whole look of my house. As expected Berg Home Improvements delivered. Thank you for my new house!

Art D. Wheaton, IL

They were clean, easy to deal with, and did my roof in one day! I would highly recommend Berg Home Improvements!
