Proudly serving the local community right here in Acworth, Georgia. John A Callahan entered the construction field at a young age as a helper for his Uncle digging footings for homes, then advanced to concrete installation. After a number of years in the concrete industry, he launched a silk fencing company, which he sold in 1997 John went to work with Blount Construction building bridges and roadways. He returned to Georgia and went to work with another roofing company assisting with in the installation of new roofs, and repairs. He has developed expertise in every facet of roofing. John will without hesitation, get on a roof to inspect, overseeing his team to guarantee correct practices. His hands on attitude is a prime example of why this company is in existence. He is a trustworthy and fair who values customer relationships.
I started helping my uncle at the age of nine digging out footings for homes that his company built. And I found that I really loved working outside, and being a ""dirt mover"". As I grew up, I found that I really enjoyed working with equipment and developing subdivisions. I now specialize in private residential work and I find fulfillment in delivering outstanding service and craftsmanship. To say the least I love my job and I love being a business owner.

Recommended Customer Reviews

If you are looking for roof repair please please please, stay away from Georgia Roof Repair. Had the worst experience with John. This guy is very sketchy, he will start of with giving you a great quote and tell you that he can do anything with a great reputation. Then he will agree to hire him and he will automatically ask for over half the payment right away. He was contracted to complete my residence, he did get over half of it finished very quick, but when it came to the residential apartment, he did not properly finish it. John had came by to finish the roof earlier in the day, he claimed he finished as much as he could, and securely tarped the roof since there was gonna be storms later that day. It was not even 5 minutes after he left that it started to down pour. Water started leaking in the one of the rooms that he had just repaired. Within 20 minutes entire room was flooded and the chunks of the ceiling was just falling down everywhere. There was water, insulation, and sheetrock everywhere.
Police came out, the fire department came out, but John never came by. We called him immediately as the ceiling started leaking, but he didn't even bother to answer his phone. He finally called back and claimed that he was already so far out of town and that he would be there in right away, 4 hours passes by, but he still did not show up. Finally around 8pm he decided to come back. Of course when he came he had some excuse as to why he was late. But really there is no excuse for the damage he had cost us. I'm not sure how this guy was even in business, I know we were not the first customers he scammed. Please STAY away from him!!! He will leave the job half done, or leave you in more damage then what you started out with. ALSO ONLY GAVE IT ONE STAR JUST SO I COULD POST THIS REVIEW. DON'T BE FOOLS THIS GUY DESERVES ABSOLUTELY NOTHING.

Horrible experience .... did not fix leak and then ghosted me 4 times to come fix it .... total sham and I noticed his work address is a house up for sale .... probably leaving town .... don't waste your time with this company

I needed some minor roof repairs, I Called this company on Monday 12/10/18 and spoke with Mr. Callahan; very cordial and pleasant. Set an appointment for Wednesday 12/12/18 for 2PM. I took the time off from work in order to accommodate our schedules. I arrived at my house at 1:45PM and called him and told him that I was at my residence waiting for him. He told me that he was working on a vehicle and that he was running a bit late. Needles to say it's know 5PM and he is a no show. WOW! A mark of a true professional. As a residence of Acworth I try to support my local businesses, needles to say I guess he doesn't want my money. Beware of this unprofessional, unreliable, and irresponsible business. Take your business elsewhere. I will be replacing my entire roof in about 1 year (CASH) You would never guess who I'm not calling ? It's people like this that give the mom and pop establishments a bad name; SHAME on you Mr. Callahan your lack of professionalism and consideration for the time of others warrants this substandard review.

Anyone thinking of using this company for your home or roofing needs, please save yourself money and heartache and do not use them!
This gentleman and his company agreed in October 1, 2017 to paint the exterior of our home. Mr. Callahan agreed to take payments after the project was complete if we agreed to pay him a lump sum of half down. Considering he had just done our roof the previous year, my husband and I naively thought we could trust him to complete this project. He and his employee who came out only a few days, did partial prep work, pressure washing with too high of a PSI, and destroyed parts of our cedar siding--which have since had to be replaced. They also used latex paint instead of a stain based paint on our cedar siding which now needs to be completely redone.
After coming both scarcely and sporadically throughout the month of October, he and his employee never did any more work after October 31st, 2017. We had perfect painting weather throughout the month of October and most of November and even the first week of December so there was absolutely no reason why this project couldn't be completed within the 4-5 weeks Mr. Callahan agreed. We left numerous phone calls, voicemails, text messages, and even a Facebook message begging for an explanation on as to why no one was coming out to complete this project which we had already put down thousands of dollars down on....with no response.
We finally had to resort to magistrate court in Cobb County, Ga due to the incomplete and lack of work on our home after we had already paid Mr. Callahan and Georgia Roof Repair $3000.00. Mr. Callahan did, at least, show up in court. We agreed in mediation for less than what we were requesting because we have continuously wanted to resolve this issue amicably. However, we now regret not skipping mediation and going straight in front of the judge for $3800 which we were requesting including court cost and additional damage to our home.
True to history, Mr. Callahan never came through on his end of the bargain we agreed to in mediation and never paid us what he agreed. And, here we are, now with a court-ordered judgment against John Callahan/Georgia Roof Repair.
We have tried to go about this entire ordeal diplomatically, legally, and are finally--8 months later--resorting to leaving an honest review online and through social media describing our incredibly disappointing experience with this company. This is very unfortunate to us as we are hard-working people and are just trying to update our home for our family and children to live.

Update: I am the only owner of my house since 2011. Also John never called be back so I don't know how that's possible. He also ""estimated"" my roof at 14 years old and would need replacing soon. Funny the house was built in 2008(model home), the roof was less than 8 years old.
I spoke with John on the phone and he was very polite and professional, made an appointment for a quote for Wednesday at 9 am. When he wasn't at my house at 10 I called and left a message. I did not hear back and called again at 2pm, he said he would be there in 30 minutes. He came out and we agreed on a price, he said he would come back and do the work on Saturday. John did not show all Saturday and didn't call. I called Sunday morning at 9am, he said he would call me back within 20-30 minutes and would have someone out on Sunday but had to check in with his crews to nail down a time. John never called back Sunday and didn't show. I tried to call John again Monday morning but he did not answer and his voicemail is full. Typical contractor attitude and customer service.

Hands-down the best roof company in the state of Georgia! John and Somer have A1 customer service and professionalism not to mention vast knowledge in their field and beyond. They are there for YOU, the customer, rather than just trying to make a buck! Why can't all companies be like this? I will hire them for all my roofing needs the rest of my life!
