Asphalt roof shingles are typically estimated to last 20–40 years, yet the typical roof warranties cover only 15–25 years. This means that many homeowners and businesses find themselves replacing their roofs more often than expected. But there is hope! With asphalt shingle rejuvenation, you can extend your roof’s lifespan beyond what was originally estimated. Greener Shingles has developed a patented asphalt rejuvenator technology specifically for roofing shingles, and it has proven to reduce the effects of aging when applied early enough. Let’s take a closer look at how this works.

Greener Shingles' patented asphalt rejuvenator is inspired by a similar technology used to preserve oil in roads, driveways, and parking lots. After extensive lab testing, it was reformulated for use on asphalt roofing shingles. It works by re-bonding some of the oils lost as a result of weather exposure over time and restoring them back into the surface of your roof's shingles. This helps reduce the effects of aging so that your rooftop can look better from both up close and afar for longer than you'd expect.

In addition to its proven efficacy, Greener Shingle's rejuvenator also offers environmental benefits such as being non-toxic and biodegradable. Plus, it does not require any special clothing or equipment for application—just wear long sleeves and gloves as you would with any other rooftop repair job! With these benefits in mind, it's no wonder why Greener Shingle's rejuvenator is becoming increasingly popular among homeowners and business owners alike who want to keep their roofs looking beautiful for years to come without having to replace them prematurely.


All in all, Greener Shingles' asphalt rejuvenator technology provides an easy and effective way to restore your rooftop's appearance while also prolonging its lifespan beyond what was originally estimated. By simply applying this product early enough on a regular basis, you can save yourself both time and money spent on unnecessary replacements while also enjoying the peace of mind that comes with knowing your rooftop is protected against harsh weather conditions year-round! So don't wait—give Greener Shingles' rejuvenator technology a try today!

  • I recently used Grandmark Service Company for a roofing repair project and new ductwork for my central air and heat unit. Two new solar light tubes and two exterior roofing vents for my whole house fan. First Grandmark was quick in sending out a Technologist to assess my roofing repair. The repair was done in a very professional manner with special attention paid to a down spout. I can't thank that tech enough for the excellent work and attention to detail. I then decided upon inspection of my existing ductwork to have it replaced. Again, the crew removed all the old ductwork out the top of the attic where the new exterior vents would be placed saving me a ton of clean up. Throughout this process they provided tarps on the floor and did a thorough clean up at the end of the day's work. All crew member's were professional and friendly and answered any questions. If I could I would give them ten stars. But for this review five stars will have to do. Again, thank you Grandmark service company. I won't hesitate to use you again should the need arrive.

    Recently moved to the central valley, got 3 quotes from other companies that were way over priced. They finished the job in less than two weeks. Highly recommend this crew..will be using them for solar install in the future
