Columbus Roofing Contractor Customer Reviews

is Rated: 5 / 5

We had a leak around our chimney that needed to be fixed. I called George at GKG on a day I was off work and he was able to come that day and take a look at the leak. George took me on the roof and explained exactly what they were going to do. He explained all the certifications his team has and the experience as well. He didn't try to sell me an entire new roof like other companies, when I knew my roof has about 5-7 years of life left. His team was able to come out the next day and fix the leak and the dumpster they used was gone that night like nothing happened. The leak has been fixed and I am a very happy customer. When I need a new roof I know exactly where I will go, GKG. You should too.

This company is A+. They were able to get the job done quickly, even right after a major storm. Communication was clear and timely. Very affordable and high quality work. Don't hesitate to give them a call.

Bill E.

The professionalism, pace and quality of this company is amazing! They were able to assess our case and make repairs in the same week, and we have no doubts the job was done right! That piece of mind is worth every penny.

Kristin M.

Literally just had him in my house. Great guy checked the attic and for mold and everything because he saw my kids. Was really worried that I'd have to get my roof replaced but he found the problem and fixed it quickly for a reasonable price. Thanks guys.

GKG is the definition of a great company. They are super knowledgeable, prompt to respond, and provide a great overall experience.

I was hoping for a reasonable estimate on a roof issue that was really concerning me. Instead, I got a reasonable estimate, and the work was done the same day! They are really nice and friendly, professional, and put my worrying mind at ease! Highly recommend!

Stephen C.

Very professional. Came out right away found the issue and fixed it the same day.

Ciera S.

Great service!!! We had a little leak from a few nails in our roof and they plugged the holes right away. GKG literally came and fixed our issue and gave us solutions to make our current roof last longer. We will be using them and recommending them to people in the future!

We spent several months getting estimates for a new roof, based on the fact or roof is 20 years old and was in need of some repairs. The estimates are all over the place. I came across GKG Roofing in online searching and they were also a CertainTeed (shingle we wanted to use) Select ShingleMaster, so I gave them a call. George came out, went over in detail his recommendation on work and how they would do it, and went over the estimate. Most of the other companies just bid the job, giving me what it would cost, but didn't go into any detail on explaining the work, the materials they would use, why, etc... It was encouraging to hear honesty from a contractor. His team did a great job, cleaned things up too well after completion, and we are very happy with their work. We would highly recommend and trust George and GKG Roofing.

Integrity, true to word and professional company! GKG Roofing accommodated my tight timeframe for getting a new roof installed after discovering a leak in my ceiling. George, the owner of GKG, came to my house within a day and immediately diagnosed the problem and showed me photos of the problem and within a couple days (due to a weekend) had a proposal for me that was less than I had originally anticipated. Upon reaching an agreement of schedule and material to be used, I signed a contract with GKG without even getting another quote because I was so impressed with his personalism and methods. Having installed roofs myself in my 20's and 30's, his methods for installing were second to none and was true to word in the contract, having watched his crew remove the old shingles, replacing rotted sheeting and installing the new roof. The crews didn't pound old nails into the sheeting but actually removed them. I cannot say enough about my experience with GKG Roofing company. If I could give 5 or more hearts instead of stars, I would because I absolutely love my new roof. The process from beginning to end was very smooth and even the crew was curious by calling me sir and accommodated any requests I had, which weren't many. They even were working well past dark to clean up the scrap that didn't make it onto the tarps. Thank you GKG Roofing for your hard work, friendly and courteous attitude. The crews seemed to want to do the job and do it right. I could go on and on about this company but if GKG would like to use me as a reference, they can. Thank you, thank you, thank you GKG for everything and all your hard and prideful work. I even tipped each of the workers $20 each (I'd have given more had I had more cash in my wallet) after the roof was installed. 5-star rating from me and more if I could!!

Brian S.

Five stars for sure. Old school prompt, courteous, conscientious service with attention to detail. Recommended.

John M.

MY CEILING IS DRY!!!!!! George and crew did a great job on my flat rubber roof. I had 4 other companies out to scope the job and chose GKG mainly because he was the only one who didn't flake. He said he would fix it, and he did. He was pleasant to work with and made it all very easy. Price was fair. Other companies wanted double because it wasn't a big job and worth their time. So hard to find people who care anymore. Thanks George!

Bodhi E.

Great experience! Showed up when he said he would. Did the job quickly and followed up just to let me know the work was done without any issues.

Doug P.

I highly recommend GKG Roofing! I feel they are very fair and honest, I cannot overstress the honest part!! It was such a refreshing experience and I am so very grateful for the prompt response in repairing the leak in my roof.

Cheri T.

Called them and they responded quickly. They came out and were able to fix our problem! Was very friendly and reasonably priced. Would highly recommend and will be using them again in the future.

Nicole B.

Fast, professional, and very helpful!! Highly recommended

Ryan F.

I found the owner of GKG Roofing to be very knowledgeable, professional, honest and timely...which is important if you have a leaky roof. Not only did the owner George Gilliland find the problem, he made sure I understood the problem and what repairs were needed. Now I understand why GKG Roofing has an A+ rating with the BBB. I would recommend this company to anyone.
Since this post, I have moved and we had GKG Roofing out to put on a new roof on our new home. Just like the previous job, GKG Roof did an outstanding job. George found that portions of our existing roof were not vented properly, and that was causing some structural damage. George and team fixed the issue and put on a lovely new roof. Thank you!

Gail H.

GKG Roofing is the roofer to hire. George and crew did an excellent job on replacing our roof. GKG made the entire process so easy from getting the quote to actually getting the roof replaced. George and his crew replaced everything from the decking to the shingles with a great price and quality materials for our new three dimensional shingle. They were professional, worked quickly but yet took their time to make sure everything was done right. The crew was good about cleaning up and making sure no mess was left behind. Delivered everything as promised with no delays. Again, this is the company to hire to replace your roof! Thanks George!!

Susan S.

George and the crew at GKG Roofing recently completed some work for us on our home. When I called George, he came out that very day to survey the job. George was very responsive and his crew completed the work very quickly and efficiently. His crew is very skilled in roofing repair, siding, chimney repair, etc. The crew was very personable and easy to work with. You can trust GKG to do a great job for you! Do not trust just anyone with your home roofing/siding/chimney repair. I will highly recommend GKG Roofing to all my friends and family.

Liz E.

This is the second time I've used GKG, both minor fixes, but with the excellent service and cost they provided the first time I had to choose them again. George is the person that came to my house both times, he's very friendly and upfront. Thanks George and GKG, I appreciate the great service.


On Saturday, June 16, 2018, we had a wind sheer come through Pickerington that landed 3 tree branches through our family room ceiling! My daughter & I were scared to death. We proceeded to clean up the water, remove the branches from inside our home and mastermind our plan to restore our home and hearts back to pre-storm. We had no idea who to call to repair our roof and gutters when I had an epiphany to go local. And how happy I am that I did. I googled local roofers near me and GKG Roofing came up on my feed. I called and left a message on Monday the 18th and within one hour the owner, George, called me back. I told him what we were dealing with and he told me he would come out before the day was over to tarp off the holes, which he did. Then on Tuesday it rained again and he had to come back out and put on a bigger tarp cause we had more holes than we initially thought. George got up on our roof in the rain and got soaked working against the elements to insure that we wouldn't have any more water inside of our home. Throughout this entire ordeal, George was so patient with us. He answered all our questions, offered his expertise on the selection of replacement materials and did an excellent job repairing the holes, roof and gutters! The workers cleaned up beautifully each day and used a special magnetic tool to collect any nails that may have fallen to the ground that my fur babies could get hurt on! We are so happy that we found GKG Roofing and truly feel that we not only found an excellent roofer but also an excellent friend!

Jenise C.

We had spoken 3 other roofers and estimators about our project. George was spot on with all that was discussed. A seasoned pro. The product is just what we wanted in design , tones and quality. His crew was of local professional tradesmen skilled and mindful of all that was going on at all times. The job had challanges, steep, high, several ridges and valleys , and brutaly hot conditions. The crew did a great job. GKG will get all of our work from here forward. Most highly recomended. Thanks George , be proud of what you and GKG bring to the table.

Bill L.

George helped us with a total roof replacement. He did a great job helping us with all of the steps dealing with an insurance claim. His employees were professional and did a great job.

Holly G.

I had an appraiser say my roof was leaky and would not consider my house marketable until inspected. George was putting a new roof on my parents house and offered to come out to take a look at mine. Very quickly he was able to confirm the roof had no issues and was happy to provide a report for the appraiser verifying. Will definitely contact for any work that may need done in the future.

Ian C.

Great work and reliable to be honest. Completed the job and even came back for a touch up making sure things look good in all this rain! Thank you!

Zack W.

GKG Roofing replaced my gutter system for me and I must say they did and excellent job. Work was done in a timely manner. Workers were very professional and clean up was excellent. Thanks George--keep up the good work.

Charlotte W.

George came to our home and went over the entire process, step by step, since we needed everything replaced. GKG Roofing replace original boards, skylights and roofing. No surprises--exactly what we agreed upon. Workers were very polite, professional and cleaned up daily. George was great to work with and we would highly recommend GKG Roofing to anyone needing a roof. Our new roof looks AWESOME, Thanks so much George

Janet D.

We recently had GKG roofing put a new roof, gutters, and downspouts on our home. We are very happy with the end results. George took the time to sit with us and show us every step of the way what was going to be done. From tearing off our two layers of our old roof and preparing our existing decking for the new one. George and his staff were professional, courteous and respectful to our property while doing their job. He has added great curb appeal to our forever home. Thank you George to you and your staff!! Randy and Sharon Miller

Randy M.

George did an excellent job in helping us with our insurance claim after we had severe storm/tree damage. He was professional and his crew did a superior job installing the new roof. Highly recommend GKG Roofing, not only do they value your business, George treats you like a good neighbor and friend, he tells you what you need and what he can do for a fair price and follows up after the job is complete to ensure you are happy with the final product. Thanks George and crew!

Richard C.

I’ve used GKG Roofing twice in the last 5 years! First, for a second story rubber roof, and just last week for new three dimensial shingles on the rest of my cape cod. GKG has the best quote, and could deliver the best quality for the money, both times. The roof looks fantastic, the job was done quick, and the guys left the yard clean. Plan on recommending to anyone I know that needs a roof!

Luke A.

Just had my roof done and I'm very pleased with the out come the workers were very professional and clean..and I would highly recomend GKG roofing to any one in need of a roof..

Niki S.

My wife and I were in a real bind. We were preparing our house to go on the market and a bad wind storm came through the area. A couple of pieces of our siding blew off and snapped in half. After dealing with insurance, they discovered that the house siding needed a full replacement. We were in a time crunch due to a new job and got quotes quickly. We are thankful we chose GKG Roofing. Not only was George's customer service prompt and professional, he understood our personal situation and made the job happen in just two weeks. The siding work itself was superb. The team was courteous, professional, and respectful of our property. They helped us get the best look for our home (shutters and all) while meeting our deadline! If you want an affordable quality driven service with good customer service, GKG Roofing is your company.

Robert D.

I had a roofing issue that needed to be taken care of quickly due to all of the rain we have been experiencing. George got a crew over to my home the same day and the workers were professional, cleaned up and left my home looking better when they arrived. They also worked in the rain, very impressive! A+++

Cynthia J.

My husband and I just had a new baby when we realized there was a hole in our roof, along with some other damage. Owner George Gilliland came out right away, showed us photos of the damage and fixed it immediately! We are so grateful for the prompt response and of course the amazing work! He helped us out during an otherwise stressful time and we couldn’t be happier with the result.

Robyn G.

The company gets A+ across the board really. Very good quality of service.

Brian C.

The GKG Roofing company did an excellent job doing a complete roof replacement including all underlying plywood. Everything in the contract was completed in a timely manner on our ranch house. We are very pleased with their profession workmanship and the 10-year warranty on all parts and labor gives us peace of mind.
David B.

George came to my home after I told him about the unpleasant experiences with so-called experts who either didn't show up or wanted to make a major project out of minor flashing problem. He found and fixed the problem in a short amount of time. I only wish I would have found him sooner. If you have any roofing concerns just call GKG. You will save yourself an immense amount of time and frustration. George is honest and fair. I won't hesitate to call him again if needed.
Tony P.

Awesome job! Arrived and completed as planned for a great price. Thank you George, well done!
Vicky M.

I've had GKG Roofing come out to evaluate and replace the roof on several properties that I own. I have been very impressed not only with the quality of work but with George's knowledge and professionalism. An A+ company!!
Tree Helpnow614

George was prompt and professional. He has many years of experience which is evident by his vast knowledge of how best to meet your needs. He does not disappoint. Thank you!
Nancy W.

We had a piece of siding fall off from the very highest point on our roof that we needed help replacing, but no one would take the job since it was a small project. We started looking into buying safety harnesses to do it ourselves when I called GKG Roofing They came out later that week, fully prepared with the equipment needed and not only took care of the siding, but also fixed a vent cover that had broken (which I was planning on dealing with later on). They took a look at the gutters and the roof while they were up there and told us everything was in good shape and we shouldn't need any additional work done for awhile. GKG Roofing was professional, honest, and I would 100% recommend them and use them again if needed!
Allison B.

George was great to work with and provided outstanding customer service and product!
Karen S.

GKG Roofing provided us with prompt, professional service. Every step in the process was handled efficiently. All of aspect of the job were explained to us clearly. The job was completed on time, neatly and professionally. I would recommend them to anyone without reservation.
Martin J.

GKG provided the most competitive estimate for our full roof replacement. Communication through the process was clear and honest and work was quality. Crew cleaned up after every day and a couple of understandable issues were addressed immediately and completely resolved within a couple of hours. Highly recommend George and GKG for your roofing needs.
Michael C.

Special thanks to George and Ty for their outstanding response (FAST) and expert repair of my roof. So impressed that George knew exactly the precise shingle match and he shared some spares just in case. Looking forward to my roof cleaning next and will provide a review update. Highly recommend GKG Roofing !
Kim H.

George did a great job on fixing our roof leak. I would recommend him. He was prompt and worked us in prior to any more damage being done.

I cannot say enough good things about GKG Roofing and owner George Gilliland. To say I am impressed is an understatement! This is the most professional and honest company I have ever dealt with. When my less than two year old roof started leaking and the contractor was not to be found I was searching for another roofer. I remembered seeing George Gilliland on Good Day Columbus on Channel 4 tv. After checking with Better Business Bureau and the producer of the TV show I decided to call him. It was the best decision I could have made. He scheduled an appointment and after inspecting my roof he gave me the bad news. The former roofing company had done very shoddy work and I had mold in my attic. That was due to no ventilation on my upper roof. Also the new gutters were not installed correctly and my leaf guard was not installed correctly. That explained why I had been having ice cycles and water pouring off the gutters when it rained. George then wrote up a quote of what needed to be done. He explained everything to me so I could understand. I had intended to interview 3 or 4 other roofers. But after much thought and against all advise from friends and family I decided not to talk to other roofers. It was not an easy decision due to the experience with the former roofer. To keep this as short as possible, I finally decided to trust George. As soon as the weather cooperated George called and scheduled the work. His three employees showed up on time and worked for two solid days in cold weather without stopping. I hardly knew they were here. Their work ethic is truly impressive. They not only replaced my upper roof but fixed the gutters and leaf guards also and some other issues. Both days they cleaned up the yard before leaving. I might add they did not quit for the day until it was dark. Also, George asked for no payment at all until the work was completed. To anyone looking for a roofer all I can say is look no further. You will not be sorry you hired GKG Roofing. With all the rain we have had lately I have had no more issues with leaks. I can sleep at night not worrying about my roof. To George and the three men who did the work I want to say Thank You. They are the definition of Honest, Ethical and Professional! They went over and beyond and it is appreciated! One more thing....I was shown pictures of what they were doing throughout the project. Job well done!
Barbara K.

Thank you GKG! George came right out got on the roof in the rain and crawled around my dusty attic to give me the information I need. He did identify issues with the roof and showed me pictures but did not sell me roof fixing, yet. Need to get the chimney addressed first! Thank you!!!!
A. Russell

" We are very happy that we chose GKG for our roof replacement and would highly recommend them for any roofing needs. Of the 4-5 estimates we received from various other contractors, George was the only one who took the time and effort to inspect our attic area, illustrating his knowledge, integrity and the genuine concern he exhibited throughout the process. We were also pleasantly surprised and grateful that his estimate came at or below the others. We have a fairly large and complicated roof, but GKG did a professional, high-quality job in a few days, rather than rushing through it in a single day, as a few others had proposed. They also did an excellent clean-up job, requiring no extra work on our part afterwards. Many thanks to George & his crew!"

" George just came out to our home, and I have to say I was very pleased with his visit. We thought we had an issue with our roof, but he was very honest with us and told us we have another 10 years of life left in our roof, which was music to my ears! His honesty is greatly appreciated. He has a roof cleaning company we are looking into as well. He said this will buy us some extra life in the roof. He went the extra mile to even draw out pictures so I could understand all aspects of what is going on with our exact situation. I highly recommend this company!"

"Relief and satisfaction. Finding a reputable contractor, especially in the roofing business is a difficult one. I came across a recommendation that endorsed GKG Roofing and gave George a call. GKG provides excellent service but I'd be happier if i could give 6-stars. The whole experience from the estimate to the follow up call when the work was done was above and beyond anything I've experienced."

"In April, 2017, I initially contacted GKG Roofing because I was experiencing some leaking in my ceiling. They came high recommended by my brother in law whose roof they had recently replaced.

When I met with George, he spent time not only discussing the types of materials that he would use, but also the caliber of the roofing crew and their levels of experience in the roofing trade.

Upon the physical inspection of my home, George also noticed that my dryer vent was completely clogged putting my house at risk for fire. It was also noted that the vent was lined with an accordion type of hose, which trapped the lint. Taking George’s advice, I immediately contacted Dryer Vent Wizard. A technician came out the following day and cleaned the dryer and vent. George also replaced the accordion hose from the roof down, with a straight steel pipe to prevent the accumulation of lint in the future.

While replacing my roof, the source of my leak was discovered and George also fixed that as well by replacing the plywood, which had black mold, and ensuring adequate ventilation to the area.

I really enjoyed working with this company. The staff is friendly, professional, and courteous. Also, the price for the job was fair and reasonable.

I would highly recommend this company."

"Within a couple hours of contacting him, George from GKG Roofing was at my house evaluating a leak I had around a roof vent. He explained the inferior type of vent used in the roof and why they are susceptible to leaks. He proceeded to seal the vent and refused payment. While this is not the long-term solution, he spent his time and resources to buy me some time until I can have the vents replaced. Because of the exemplary customer service demonstrated by George, GKG Roofers will be the company I call for my roofing needs."

"Being a first time home buyer and new to the area, we always have reservations about finding an honest and professional contractor that can deliver quality results with reasonable prices and in a timely manner. We were thrilled to find George and his team did just that. George and his team were thorough in their work. What we thought was a simple roof leak turned out to be a little worse and George's expertise saved us thousands of dollars down the road. The work was done quickly despite very rainy weather and they kept us up-to-date on their progress during that time. In addition to the roof repair, his other entity, Columbus Roof Clean also cleaned our roof at an incredible price. I highly recommend GKG for all of your roofing needs. Thank you George and team!"

"George was prompt and made time to meet on my leaking skylights, Unfortunately for me they were rotten and needed replaced. Fortunately for me, and LUCK of the schedule, I was able to have them replaced that next weekend! including the rotten boards from the bad skylights, I feel confident these will last long after I need to replace the roof in about 20 years... at which time I will call GKG, I am sure based on the quality and respectful nature of the business George and his family will still be providing the high level of work that I received."

| Rated: 5/5

"Awesome experience from start to finish! George is professional and knowledgeable. His estimate to replace the roof on our 30 year old house and rehang all the gutter was very competitive. Boosted by the fact that he threw in many extras for free: replaced shed roof, removed first course of plywood and raked back all the interior insulation, installed gutter guard. His crew was friendly, communicative and informative throughout the process and cleaned up before they left each day. To top it off, George rehung an interior light fixture that became loose as a result of the banging on the roof. Our house now looks cleaner and more contemporary. Would definitely use him again and highly recommend him and his crew. Thanks, GKG!"

"GKG roofing came out and gave me an estimate on wind damage siding. I felt very comfortable with George from GKG roofing I did not feel like I was being taken advantage of on estimate like other competitors. GKG ROOFING came out one day replace damage siding and also replacing some other broken pieces around the house they done a very very good job would recommend them to anybody that needs roofing or siding work done these guys do really quality work. "

"I called 3 contractors for roof repairs after a storm blew shingles off of our house and garage. I left a message at GKG Roofing and George called me back within a half an hour. One of the others didn't call me back at all and the third one wouldn't be able to look at the roof for three days. George was genuinely concerned because it was going to rain and squeezed us into his busy schedule. He arrived within a few hours of that call and had a temporary patch in place. We also had some damage to the siding on the house. GKG Roofing installed new shingles a few days later and simultaneously replaced the damaged siding. They even put a safety spring on the storm door to prevent this damage from happening again! I highly recommend GKG Roofing and rate them 6 out of 5 stars, or 120%. We will definitely be calling with any future needs. Thanks George and GKG Roofing!!!"

"I received several estimates for the complete replacement of the roof on my 88 year old house that had three layers of shingles in some places. When George gave me his estimate, it was competitive in price, extremely clear about what needed to be done and he was very straight forward and sincere about wanting to do the job. The job was completed exactly on time as scheduled, the workers did an excellent job on the roof and keeping the worksite. "

"GKG came highly recommended, so I wanted a bid from them on my 52 square ranch home. George was very prompt to meet me and had the quote to me that night. He was thorough in his sales/estimating and straight to the point. The installation was actually performed two weeks prior to when they committed to.(I know, what contractor does that these days??) The installation crew were "steady hands","

" After storm damage on our roof at our residence I contacted a few contractors and after meeting with many roofing companies I met with the owner of GKG roofing. He was very honest and walked me through the entire process and worked hand in hand with my insurance adjustor for the services that needed to be completed. His crew came and completed my roof within 48 hours and went over and above my expectations with the quality of their work. "

" I researched many roofing companies this past spring when I was looking to replace a 23 year old roof. Received multiple quotes from both large and small companies. George's price was very competitive and he always returned my calls promptly and showed up on time. His company did exactly what they said they would do, completed a high quality job on time, and did an outstanding job of cleanup upon completion. "

"We had GKG roofing out to our home after we discovered a major leak in our family room. George Gilliland the owner was there promptly and on the date and time we scheduled. George was able to thoroughly diagnose the problem and present us with our options to solve the problem. We are now confident we will have no roofing problems for many years to come. From start to finish we are extremely pleased with the service we received. "
