Extend the Life of Your Roof—Without Replacing It
A Smarter Solution for Aging Shingles
Your roof might be older, but that doesn’t mean it’s done. With our professional Roof Rejuvenation service, we clean and re-oil your shingles to restore their flexibility, protect against further weathering, and add 5 to 10 years of life to your existing roof—all at a fraction of the cost of a full replacement.
How Roof Rejuvenation Works
Over time, asphalt shingles lose their natural oils, become brittle, and break down under the elements. We use a plant-based, asphalt-friendly treatment that soaks into the shingles, restoring their flexibility and water resistance.
- Removes moss, algae, and stains
- Replenishes lost oils and granules
- Helps prevent leaks and cracking
- Improves curb appeal and roof performance
- An aging roof you’re not quite ready to replace
When Should you Consider Roof Rejuvenation?
If you notice any of the following, it may be time for rejuvenation:
- Dark streaks or algae growth
- Moss or green buildup
- Curling or cracking shingles
- Faded or discolored patches
- An aging roof you’re not quite ready to replace

Jason and his crew did a fantastic job doing our roof. Cleaned things out of the way and put everything back. Couldn't tell they were here cept for the new roof. Jimmy was great salesman and Mitch came the morning of to say hello.Dian D Phillips2025-10-03Trustindex verifies that the original source of the review is Google. Because there was a leak, I needed to have a roof replaced on a back porch room. I want to say that working with Guarantee Roofing was a wonderful experience from start to finish. From the moment that Cole came to the house to discuss what was needed - to the estimate process, to the work done by Mike and Mason - it was all smooth and professional. An estimate was provided by Cole, who explained the entire replacement process without pressure. I was able to choose the color of shingles, then given time to study the estimate before accepting. There was no pressure, and a total willingness to answer my questions. After the work was complete, they came back to check the work and see if I was satisfied. They even came back and caulked the interior corners to correct some minor shifting (it's an OLD house). I was very happy. Then, I had the garage gutter cleaned out and had metal gutter guards installed. Josiah came to do that job and very quickly had it finished. He also sent me photos throughout the process so I could see it from start to the final installation. In summary, I highly recommend Guarantee Roofing and would contact them again for any future projects.Joanna Dailey2025-10-02Trustindex verifies that the original source of the review is Google. My experience began with Mike Byrd, who handled the insurance claim and many other things behind the scenes! The roofing team was excellent. I have a two-storey, high pitched roof and the roofers installed the new roof expertly. The fence needed to be repaired and new gutters were needed as well. I was so glad to be guided through the process with the insurance company by Mike, as it was very drawn-out and confusing. I am very glad I chose Guarantee Roofing!MargaretMary Welch2025-10-02Trustindex verifies that the original source of the review is Google. The Guarantee Roofing team of Ben, Glen, Josiah and Leah were great to work with. They cleaned and repaired our gutters very professionally and efficiently.Patrick2025-10-01Trustindex verifies that the original source of the review is Google.

Nick, Denim, and John did a great job on my fence I’d recommend them to anyone !Nita Livvix2025-09-28Trustindex verifies that the original source of the review is Google. The folks at Guarantee are knowledgeable and professional. Cole came out and provided an estimate and also checked the roof. He told me about the process and provided a timeline for when the work would be done. He called a day before the crew came to do the work. They were fast and efficient and did a great job on replacing the fence. Special thanks to Steven, Abell, Timmy, Denim, Nick and John.Zack Keyes2025-09-25Trustindex verifies that the original source of the review is Google. Awesome job! Steven, Timmy and Abel were fantastic! Fence looks great!Matthew Switzer2025-09-25Trustindex verifies that the original source of the review is Google. My parents asked me to write a review on their behalf because they weren't sure about the online review process but wanted to share their experience. They were very pleased with their experience working with Cole on an initial estimate to replace their prior fence that has seen it's better years. I will commend Cole on the sales process working with my parents to meet their needs all the way to his installation team Nick, John, and Denim, who took the extra time to make sure things were the way my parents requested. My Dad utilizes a wheelchair so isn't very mobile but Nick took the time to talk to him in detail the day of installation as they got going to assure him of all they planned to complete. He then confirmed with the final inspection to make sure they were pleased with the install. Nick, John and Denim did an outstanding job on the fence install and my parents have received multiple compliments on how nice the new fence looks. We wanted to give a shout out to their front desk ladies who were very courteous when we stopped by to drop of the initial deposit on the job. Customer service is so critical because it is what drives the customer experience and potential returning customers so it is nice to see a company that still is committed to customer service! Overall, 10/10 experience from initial estimate, general customer service, installation and post install follow-up! Highly recommend Guarantee and hopefully you get to work with Cole and his install team Nick, John and Denim.
