BD Wolf2025-03-19Trustindex verifies that the original source of the review is Google. I had gutter guards installed by Klemm Exteriors about a year and a half ago and it was a good experience. So much so, I hired them reroof my home last November. Klemm uses quality materials, they have years of experience, and their employees care about doing a job well. It’s satisfying to hire a good company like this. Their customer service is GREAT. C H2025-01-31Trustindex verifies that the original source of the review is Google. We have used Klemm Roofing for repairs in the past- they were always honest, responsive and did quality work at reasonable price. We were having some issues with a leak from our skylights late last winter, and Steven from Klemm came out and noticed there was significant hail damage. We filed a claim and eventually were able to gain approval for a new roof, skylights and siding from my insurance company. Jeff at Klemm was a great help throughout the process. He was present during the insurance company inspection, helpful in addressing issues from my claim and assisted in picking out our new roof and siding. The installers were excellent- they exhibited quality craftsmanship and were very respectful of our property cleaning up every evening and upon job completion. Jesse did a great job keeping us updated as the process and addressing any concerns with the job. We are ecstatic with the outcome of the project. We feel we have the nicest looking home in the neighborhood! Thank you Jeff and everyone at Klemm! Eric Oja2025-01-31Trustindex verifies that the original source of the review is Google. I wanted to take the time to thank G Klemm roofing and especially Steve Borodaj for assessing my condensation issues throughout my home. Initially the suspect of water stains on my cathedral/vaulted ceilings and in our master bedroom were due to a newly installed roof about 1 1/2 years ago. Naturally I wanted a 2nd opinion by a very referred company. I reached out to G Klemm and they were able to schedule a home inspection the very next day. Steve Borodaj was very professional and had a vast knowledge of many common issues seen in the homes throughout Mill Creek. He was able to give me a diagnosis of the true root of the problem and educate me to prevent any further issues and potential damage. My wife and I plan to use G Klemm roofing for future projects that they offer services for such as painting our exterior cedar siding. Knowing what I know now and the positive experience I had with Steve, I wish I would have known about G Klemm roofing to select them as my roofing contractor a few years ago. Thank you for all your help and I will reach out to you soon for a quote on our home! Eric Oja Justin Miskawitz2024-12-06Trustindex verifies that the original source of the review is Google. Ya....Do yourself a favor and just choose these guys for roofing. They come on time when they say they will, they are communicative from the office, they clean up after themselves and the roof looks perfect. They care about their customers and you can tell immediately. Jeff came out to my house and he was great. They also do Christmas lights and were $300 less expensive than a competitor and the lights are perfect. Dawn Greene2024-11-20Trustindex verifies that the original source of the review is Google. We recently moved to St. Charles, and I saw a posting by G. Klemm Roofing & Exteriors for installing Christmas lights this season. Since my husband and I are getting up there in years, I thought it would be a perfect time to have someone do the work for us. They did a great job. The installers were friendly and professional, and the house looks ABSOLUTELY AMAZING! I highly recommend them. If it is something you have considered doing, make the call, you won't regret it. Nancy Chapp2024-06-08Trustindex verifies that the original source of the review is Google. This company put a new roof on our house today. We had a wonderful crew that were very respectful of our property and did an awesome job. They were here at 7am and worked until 9 pm. Jessie helped us pick the shingles and his choice was spot on. We couldn’t be more happy. Thank you to everyone at Klemm Roofing. Len and Nancy Chapp Joe Giandonato2024-05-30Trustindex verifies that the original source of the review is Google. Easy to work with. Jeff Rosier was very professional and incredibly knowledgeable. Very honest and upfront with the whole process, not like some of the storm chasing roofing contractors in the area. Josh Crost2023-11-28Trustindex verifies that the original source of the review is Google. Team was quick and efficient. Couldn’t be happier. Thank you! Brent Busby2023-10-07Trustindex verifies that the original source of the review is Google. We have used G. Klemm Roofing several times and they have always been amazing. They are thorough, friendly, and always help ensure you know whether something is damaged or not. They will always be my choice for roofing work. Michael Nicholson2023-09-13Trustindex verifies that the original source of the review is Google. I previously used G Klemm roofing for a small roof repair project and once completed I was impressed with cost and quality. Fast forward a few years when a storm caused hail damage to my home and my FIRST thought was G Klemm. Once again the project was discussed, estimated, and at project end I was happier with all final results than I thought I could be - they really are a honest and reliable team to work with and I will not hesitate to call upon again should the need arise. Very happy indeed!Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
