Summary

Roof rejuvenation restores asphalt shingles by replacing the petrochemical oils they lose over time with plant-based oils. The solution used is eco-friendly and can extend the life of your roof by enhancing shingle flexibility, durability, and hail resistance without increasing fire risk. Unlike a full roof replacement, which can take days and disrupt your life, rejuvenation takes just two to three hours. It also costs up to 80% less than the cost to replace the entire roof.

Asphalt shingle roofs don’t last forever, but there are a few steps you can take to help them last longer over the years. Roof rejuvenation is one of the most popular options because it can help you put off early replacement and prevent the need for costly repairs.

 

Below, we explain our approach to roof rejuvenation at Roof Maxx so that you can understand its potential and decide if it’s right for your roof. You’ll learn how this technology actually works, how it compares to the process of replacing a rooftop, and whether it can help you save thousands on property repairs.

How Roof Rejuvenation Works at Roof Maxx

Roof rejuvenation is a commonly used term within the residential market to describe the roof restoration process. This process aims to restore the flexibility, durability, and overall condition of asphalt shingle roofs.

 

When you restore or rejuvenate your shingles with Roof Maxx, a trained expert sprays a specially formulated mixture of plant-based oils onto the roof to help replenish the oils your shingles lose over the years from exposure to the elements.

 

Here are some quick facts to help you understand this process from A to Z:

  • All asphalt shingles contain petrochemical oils, which are made from fossil fuels.
  • UV rays, sun, rain, wind, and snow dry these oils out over time, making shingles brittle.
  • At Roof Maxx, we use a safe, eco-friendly solution that softens old, dried-out shingles.
  • Spraying the treatment onto your shingles restores their flexibility and prevents the kind of cracking that happens when they’re dry and brittle.

On average, each treatment can extend the life of your roof by up to 5 years. It can help you get up to 15 more years of life out of your shingles if you re-apply it at regular intervals.

Roof Rejuvenation vs. Roof Replacement

The roof rejuvenation treatment we use at Roof Maxx can be an effective way to make the shingles on your roof last longer, especially if they are not yet cracked or otherwise damaged. Roof replacement is very different and involves totally replacing all of your shingles with new ones.

 

Each process is designed to solve a different problem, so they aren’t really interchangeable. Below, we’ve created a comparison chart that makes the differences clear:

Feature Roof Rejuvenation (Roof Maxx) Roof Replacement
Typical Cost Up to 80% less than the cost of a full roof replacement $20,000–$30,000 for an average home
Intended Use Extend the life of an existing asphalt shingle roof by up to 15 years Completely replace an old or damaged roof with new materials
Time Required 2 to 3 hours for most homes 1 to 3 days, depending on roof size and complexity
Environmental Impact Low (uses eco-friendly materials and reduces landfill waste) High (involves removal and disposal of old shingles, contributing to landfill waste)
Disruption to Home Minimal (no loud construction or debris) High (potential noise, debris, and temporary inconvenience to homeowners)
Effect on Home Value Moderate (extends the lifespan of the roof and maintains curb appeal) High (new roofs are often seen as a significant home value booster)
Maintenance After Treatment Annual inspection recommended Annual inspection recommended
Best For Roofs that are 5-25 years old and structurally sound Roofs of any age that are nearing the end of their lifespan or are severely damaged

How to Choose the Right Option

As you can see from the above, the choice between rejuvenating your roof and replacing it usually comes down to the age and condition of your rooftop. It’s not a question of which approach is better; it’s a question of which one is more cost-effective based on your needs.

 

Many homeowners mistakenly assume roof replacement is their only option. Jumping to this expensive process even when your shingles can be rejuvenated for a fraction of the cost means you’re spending money unnecessarily. Exploring the benefits of rejuvenation can help you avoid costly mistakes.

Long-Term Benefits of Roof Rejuvenation

Roof rejuvenation is about making shingles flexible again so they can resist the weather. 

 

There are four main long-term benefits from choosing this option:

  1. Extended Roof Lifespan: Restoring the flexibility of your shingles helps them resist water and can make your roof last much longer than it would without treatment.
  2. Cost Savings: Rejuvenation is almost always much less expensive than a full roof replacement. That means you have more money in your home-improvement budget for other projects.
  3. Environmental Benefits: Restoring your shingles with rejuvenation reduces the amount of roofing waste that would otherwise end up in landfills. That’s a win for the planet!
  4. Improved Appearance: While it isn’t the main benefit, rejuvenation can also make your roof look newer again by revitalizing the color and texture of your shingles.

Benefits like these prove that rejuvenation has an important role to play in long-term roof maintenance. If you’re getting the maximum amount of life out of your shingles, you’ll spend less on your roof over time.

Does Roof Rejuvenation Really Work?

Roof rejuvenation is still a relatively new process, so it’s easy to be skeptical or assume it’s “too good to be true.” But there’s a surprising amount of both scientific and anecdotal evidence available to back it up.

  • Paul Herchenbach’s roof make it out of a major storm unscathed
  • Becca Switzer restore flexibility to her 17-year-old shingles
  • Dennis Gurgone save his home insurance policy

Results like these speak for themselves, but the science behind the process is just as important.

The Science Behind Roof Maxx

A study conducted by Ohio State University looked at the effects of Roof Maxx when sprayed on 17-year-old asphalt shingles. 

 

Here are some of the results:

  1. Shingles sprayed with Roof Maxx were significantly more flexible than untreated asphalt shingles, suggesting better durability and wind resistance.
  2. Roof Maxx also improved the granule adhesion of the shingles it was sprayed on, suggesting that it can restore their condition to nearly-new levels.
  3. When sprayed with Roof Maxx, asphalt shingles showed no increased signs of flammability. This suggests that Roof Maxx doesn’t increase your risk for a fire.
  4. Hail damage to shingles sprayed with Roof Maxx decreased by 24%, further demonstrating that Roof Maxx helps your roof resist impact damage.

The reason evidence-based options like Roof Maxx are so popular is because they work really well when they’re applied at the right time. It works even better when paired with other roof care strategies.

Experience the Benefits of Roof Rejuvenation for Your Home

Unfortunately, there’s no way to make asphalt shingles last forever. All roofing materials will eventually reach the end of their life cycle and need to be replaced. But that doesn’t mean there’s nothing you can do to put it off and get as much life out of it as possible.

Roof Maxx is a safe, eco-friendly, and affordable alternative to a life-disrupting asphalt roof replacement that won’t harm pets, kids, or the environment. Find out how much you could save by getting a free quote today.
