We serve Springfield, Ozark, Nixa, Willard, and everywhere in between.

A-1 Guarantee Roofing was founded in 1992 by Brian Garber, a lifelong roofing industry professional and resident of Springfield. Together, Brian and his wife Sally grew the business from a single-truck operation to one of the largest roofing companies in Springfield with over 20 full-time employees.
A roof is much more than simply a coating for the top of your home. It's a complete system, with parts like roofing underlayment, flashing, and ventilation all working together to make your house dry, safe, and energy-efficient. That's why, when you need a new roof, it's important to hire lifelong roofing professionals who understand all the components of a roofing system, not just some guys who know how to nail up shingles.
A-1 Guarantee Roofing will handle any job all the way down to a leaking carport, but we're also capable and equipped for the largest commercial jobs. The Drury Science Center in Springfield and St. John's Clinic in Nixa are just a couple of recent examples. Commercial roofs are generally higher-maintenance than their residential counterparts.
When a roof needs repaired the project is usually very time sensitive. A-1 Guarantee Roofing understands the vital nature of roof repair and can provide on-site professionals quickly to fix the problem whether its a commercial or residential project. You can trust our years of experience to get it right the first time.

Friendly people to work with and they do good work but, be sure to get estimates in writing before submitting to insurance. They'll charge every penny your insurance pays out, even if money was allotted for other things such as roofs on outbuildings. One roofer cussed like an absolute sailor while there. I picked up roofing nails by the handful for nearly a week.

Also left sharp metal shavings, gutter nails and debris from gutters absolutely everywhere. Didnt put elbows on two downspouts as they said they would and left the rain sensor for my sprinkler system just laying in the side yard. Only gave 4 stars because they were quite kind to deal with and they do qualify work.

We are very pleased with the attentive and professional care given in the replacement of our roof. Troy Johnson was very helpful throughout the whole process, from assessment of damage of our roof, arranging the repair work, communicating with our insurance rep. The work was completed very quickly, efficiently, and professionally. We relied on Troy completely, and he was extremely attentive to accuracy and detail. Thank you for all the work done on our behalf. Stephen and Rita Hagenhoff

From the time I called A-1 to the completed project communication was wonderful. When Chad came to look at my roof I had already seen 2 other companies. I felt that Chad was honest, knowledgeable and made sure that I understood what the issue was. The project manager Chris kept in contact with me in regards to the actual project and timeline. The guys who came out to make repairs were efficient and cleaned up really well. Thank you again for great service!

I HIGHLY recommend A-1 Roofing If you want an truly HONEST, hardworking company then this is the company for you! I can't begin to tell you how wonderful this company and their staff is! Chad was so kind, understanding of my needs and courteous through the quoting process and beyond! If you need all the t's crossed and the i's dotted this is your man!

The installation crew of NINE were incredibly respectful of our property and did such quality work in a very timely fashion. They kept things picked up as they went and removed debris each day! The onsite inspectors and crew leader made sure all the contract details were adhered to, as well as doing a final inspection of the installation to insure everything was as it should be!

The job was completed on-time, with no "surprises" or upcharges(as other companies tried to tack on), everything is PERFECT and now my neighbors now have roof envy! If you look at my photos you will see not only how beautiful it looks, but the great care taken during the process to protect my property

We signed with A1 to re-shingle our home. They seemed to do an excellent job. When we signed the contract with Chad he was very knowledgeable about what A1 would do and answered my questions. I had one specific question concerning my backyard.we have dogs that needed to go out now and then. The yard IS fenced and I asked if the crew would be in the back at all.

His reply was "yes for clean-up and such". I told him that the gates HAD to be kept closed. He said he'd inform the crew--. *PERSONAL NOTE*-- When the crew started work, we told them about the dogs, fence and the gates HAD to be closed if the crew went into the back (dogs were never in the yard when the crew was working), they assured us they would make sure gates were closed.

After day one they asked to place ladders in the back to prevent them from being seen from the street after work, which we agreed. After they left, I happened to go out and found a gate left wide open. Had I let the dogs out, they would have been gone. We told the crew the next day about the open gate and they said they would "be more careful". The last work-day was Saturday, Sept.4th.

When the crew finished the job, they cleaned up all around the house. Before they left, we said goodbye and I asked one of them if the back gates were closed. They replied "Yes, they were sure they were shut" It was after dark, so I let the two dogs out as usual. One came in but the other was still out. After a half hour, she still had not come in which was not normal.

I went to look and found a gate left wide open and the dog gone. We drove and walked all the area looking for our dog. We had flyers made and posted in stores and yards.even posted on social media. By Monday we thought our dog was gone for good. On Wednesday, we had a call from a lady saying she found our dog.nearly two miles away from our home. We picked her up.she was hungry, thirsty and very scared.

Somehow she managed to go across 2 very busy streets. Sunset and then South Campbell) without being struck by cars. She had been missing 4 days. We had raised them from 8 weeks old and they are 7 years old now and it was like losing a part of the family as much anything can be. If you have a pet, you know how we felt. We had told the company people (who came out later to check the job) about the gates left open and losing our dog and their response was, like, "TS. Mac" ( any vets out there will know what THAT means) they didn't care. OK.rant over. I can only hope they put on shingles better than knowing how to close gates!

These folks were amazing! Showed up on time with a full crew, stripped the shingles off of our house and replaced with new in under 2 full days. We have a fairly large house and the efficiency was unbelievable. Cleaned up great around the house, was courteous and professional. Not to mention their pricing was better than other companies and wasn't because of lesser quality or materials. They also offered transferable warranty at no extra cost that others wanted to charge for. You won't regret calling this company.

Very professional from our initial meeting with them to the completion of our new roof. We originally contacted Chad at A-1 for a roof inspection when buying our new home. He provided excellent feedback and reasonable price for some minor roof repairs. Over the next 4 years we called Chad many times for advice on roof leaks due to an aging roof and he was always available to stop by within 24 hours.

After hail storm damage we finally decided it was time to replace the roof and A-1 did a fantastic job. The crew was very professional and provided high quality service. I would highly recommend them!

A-1 Guarantee Roofing was recommended to me and that proved to be a great recommendation. I do not live in Springfield, but was helping my mom with her roof repair. A-1 kept their appointment, understood our needs, and made good recommendations. They kept me informed along the way as to the status of our project, did a great job of cleaning up and the roof and gutters look great.
