Klemm Exteriors

There is a reason that Klemm Exteriors has so many five star reviews - they deserve it! They have a long history of making customers happy. Excellent communication about the process upfront, followed up by a skilled team of roofers and an onsite Project Manager, Jesse, who keeps you informed on progress every step of the way. No surprises, no hiccups, no problems. A positive experience from start to finish.

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.

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!

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

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.

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.

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.

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.

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.

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!

Hired these guys off the recommendation of a chimney company and they were quick to get us a quote and got to work within the week. The job was super seamless and looks great! Hope I won’t need them anytime soon but if I do I know who I’ll be contacting.

We had our roof replaced due to the hail storm last September. Even though many storm chasers knocked on our door, we waited until G Klemm roofing could inspect our roof. We found we did have damage and went ahead with the replacement. We had the best group of workers, they protected our shrubbery and windows with plywood and tarps and netting. They swept the ground constantly for nails. And cleaned up everything. Our new roof is beautiful! We would highly recommend G. Klemm roofing for your roofing needs.

I don't usually write reviews, but these guys are AWESOME! We've used them for various projects, including gutter guard installation, bathroom fan installation and roof/wood repair due to water damage. Steve is great to work with. We would not hesitate to use them again for any project!

The September 18, 2022 storm that passed through Geneva pummeled our roof (including copper roofing) and gutters, and they had to be replaced. In the past, we had used local roofing contractor, G. Klemm Roofing, to inspect our roof and do minor repairs, and so we knew of their great work and reputation. They were top of mind, even though they didn't come knocking on our door like the 15 - 20 other roofing contractors did.

Jeff Rosier and his team (both in the field and the office) took care of everything from the first inspection, to dealing with the insurance claim, to roof and gutter installation, to final cleanup (they even sweep the yard and driveway with magnets to pickup nails and metal scraps). They took all the stress out of the process. They are the most professional, fair, and reasonable contractor I have ever dealt with, by far. They warranty their work, to boot. So, no surprise why they have stayed in business for 29 years and get top reviews.

Family-owned super great company to work with. Honest and fairly priced. Their communication with the client is superior. I highly recommend them.

I met with Jeff to have him evaluate my roof from recent storms. He found hail damage and worked with me to file for insurance coverage. My insurance company pushed back and initially turned it down. Jeff fought the decision and got it reversed. Two weeks later they came out and did a GREAT job installing the new roof, copper flashing and gutters. Everything looks great. There are a lot of shady roof installers G Klemm is not one of them. They are honest, responsive and exceeded my expectations. Thanks again!

Klemm roofing is a good company. My wife has a local business in Geneva so we try to use local, small business for our needs. I called them a couples years back to fix some lost shingles and they did not recommend to replace the roof. By now I'm losing more and more shingles and I used them to replace the roof. Reasonable quote and they are using top notch material (Consumer reports rated the shingles as the best ones). Also everything comes with a warranty. Jeff is super knowledgeable and a great guy to work with. I'm happy with my new roof.

I can't say enough about these guys. They were absolutely wonderful to work with. I had an emergency roof repair and they were able to come out and fix it the next day. Jeff was extremely professional and worked with me throughout the entire process. What should have been a disaster for me turned out to me a non-event. They were a true lifesaver. 100% recommended

I needed a new roof and they took care of everything with very little effort on my part, including talking with insurance and making sure everything was covered. They removed the old roof and put the new one on and completed everything all in one day. All made for an incredibly easy process

Great service and quality work. Gave the quote and was able to fix the issue on the spot. Nick is awesome by the way.

Trustworthy and fair. I've had them out to look at my roof a couple times. First time they confirmed I did not have storm damage but identified and fixed a couple small items.

If a storm chaser says you have roof damage tell them to go away and call these guys. They are honest and local.

Would recommend G Klemm Roofing to anyone needed a new roof or roof repair!! Quality work! There is a reason why they have been in business for so many years! AAA+++

We had a couple gutter issues that Nick was able to fix correctly and quickly. The whole process from initial contact with G Klemm roofing was professional and pleasant. The office staff (Mary & Pam) are awesome!

I just want to give a shout-out to Klemm Roofing. This company is excellent. We've had them come out twice now. Once for a repair around a skylight. Instead of telling us we had a major repair, they fixed the seal around the skylights. Four years later, it's still good. This week, we had them come out to see if we needed ice removed. They told us we did not, AND they didn't even charge us for a service call. Honest and fast. I'd recommend Klemm without any qualms.

I have used G Klemm on several homes where I could not safely handle the work on the roof. They are always prompt, courteous and provide a great value. Always my first contact for anything on the roof.

Excellent experience with G Klemm Roofing. I thought I had a leak in my skylight, but Steve inspected it and advised I have a condensation issue possibly exacerbated by a minor issue with the skylight. Point is I can wait for any repair and no charge for the inspection. I am unemployed so especially appreciate they care as much about their customers as they do themselves in the short term. G Klemm is an honorable business.

Great service and responsiveness. Jeff Rosier did an amazing job representing us and was very persistent with the insurance company. We had an amazing experience and highly recommended the company.

Thank you Klemm roofing. We had constant trouble with our smoke- carbon monoxide detectors sounding alarms despite the fact I replaced the batteries. I even called the Geneva fire dept, and they found no monoxide but that our detectors were 12 years old and needed replacing. I installed 7 new detectors and the alarm kept going off. I took them down and found drops of water in one of them. I called Klemm roofing and they came out the next morning . He inspected the roof and attic and found that two of our bathroom fans were vented to the side of the house instead of through the roof. Nick came out and installed piping and two new vents were installed in the roof. More importantly we were told
By Klemm the moisture in the detector was caused by the ice on the roof. It is a common occurrence and there was no need for a new roof.
Thanks Steve, Nick and the trustworthy people at Klemm roofing

Great service and fair pricing with amazing response time when I had a tree put a hole in my roof!

Prompt, immediate response. No nonsense, friendly, serious professionals. The gave me the feeling that they really cared about my leaky roof issue. Reasonable, up-front price estimate was met on time and it was fixed earlier than I expected. What's not to like?

I called this company for my 78-year-old father who had a leaking roof and is ex-roofer himself. They sent somebody out several days later to inspect the house. They told my dad that it was it a simple job that required the vents being replaced because they were put in wrong the first time (not by my dad). Their man came out at the appointed time and spent less than two hours at my dad’s house fixing the problem for less than $300 total. My dad is extremely happy and pleased with the service and quality of work he received. He told me to give this company the highest rating I could possibly give them, so I am.

G Klemm Roofing did a great job on my roof. I had an estimate within 1 day of contacting them and the work was scheduled for 3 days after that. The roof was completed from start to finish in 1 day. Workers were hard working and courteous. Highly recommend!

From the very first appointment until the drop off of the warranty information, this company was one of the best and most professional I have ever dealt with. We got several quotes, Jeff worked hard to be competitive and was. I never had to chase them down for an appointment or a reply to an email sent. In fact Jeff was always on point and in touch with me before I had a chance or a need to reach out. I was well informed of all aspects of the job, the crew was fast and efficient and all work was completed within a day and a half. My roof looks awesome, the work is top notch and you can see the quality and care that was put into the job. The follow up from Jeff was awesome as well, and he made sure after it rained that we were leak free. I will never recommend another roofing company. Seriously one if not THE best around. I was dreading the roof replacement but because of Klemm roofing and their staff...I was at ease 100% of the time. Amazing results through and through.

This is the second time I've used G Klemm Roofing and this experience was as good as the last. We have an older roof with two layers of shingles, which we know will have to be replaced but in the meantime, we are fortunate to have only minor issues. The first time we used them was in December 2014 for a small leak repair around our chimney vent and that fix has held up. This time the issue was pertaining to the roof area that extends over our front porch.

Like the last visit, roofing repair specialist Steve called ahead to give a 10-15-minute eta and then arrives promptly. Steve is very professional and personable and explains what he is going to do before getting on the roof and then explains what he discovered once he comes back down, complete with pictures. He gives a couple options to try with the understanding that, given the age of the roof, the best fix is replacement. We went with the repair and will not hesitate to use them when we get around to replacing our roof. I highly recommend them.

G. Klemm Roofing helped with the Algae problem on our roof. They had a great solution for getting it removed. Their staff is friendly and we will be using them in the future for our roofing needs.
