A Second Life for Your Roof
Asphalt shingle rejuvenation is a treatment that restores aging shingles by replenishing lost oils, improving flexibility, and extending roof life by 5-15 years—at up to 80% less than the cost of replacement.
Quick Answer:
- What it is: A bio-based spray that penetrates shingles to restore lost oils.
- Cost: $1,500-$3,000 (vs. $10,000-$30,000 for replacement).
- Time: 2-3 hours to apply.
- Results: Extends roof life 5 years per treatment (up to 15 years total).
- Best for: Roofs 6-15 years old with early signs of aging.
A full roof replacement can cost $20,000 to $30,000, but you may not need one. As asphalt shingles age, the oils that keep them flexible evaporate, causing them to become brittle, crack, and lose their protective granules. This makes a roof look worn and vulnerable to leaks, even if the structure is sound.
Asphalt shingle rejuvenation offers a sustainable alternative. Instead of sending thousands of pounds of shingles to a landfill, this process uses plant-based bio-oils to restore what time has taken away. It can extend your roof’s life by up to 15 years, save you thousands, and takes only a few hours.

What is Asphalt Shingle Rejuvenation and How Does It Work?
Asphalt shingle rejuvenation targets the root cause of roof aging: the loss of essential oils. Instead of tearing off aging shingles, this process restores them from the inside out.
Unlike a coating that sits on the surface, our bio-based formula—derived from natural oils like soy—penetrates deep into the shingle. It replaces the petrochemical oils that have evaporated due to sun and weather, restoring the flexibility and protection your roof had when it was new. For homeowners across Southeast Michigan, it’s a practical alternative to the expense and disruption of replacement.

The Science of Restoring Shingle Flexibility
New asphalt shingles are rich in oils that keep them flexible and are topped with ceramic granules for UV protection. Over time, Michigan’s weather causes these oils to evaporate, making shingles dry and brittle. This leads to cracking, curling, and granule loss.
EverNew Roofing’s bio-based solution reverses this by reintroducing plant-based oils into the asphalt. Lab tests confirm that treated shingles regain flexibility, allowing them to expand and contract with temperature changes without damage. Restoring this pliability gives your entire roof a new lease on life.
Proven Performance Improvements for Your Roof
The benefits of asphalt shingle rejuvenation are backed by independent testing, showing measurable improvements that protect your home:
- Granule Adhesion: Treatments improve granule retention by up to 86%, keeping your roof’s protective layer intact.
- Hail & Wind Resistance: Restored flexibility helps shingles resist hail impact and makes them less likely to tear off in high winds. Studies show 24% less hail damage on treated shingles.
- Fire Resistance: The treatment does not increase fire risk. In fact, some tests show up to a 40% improvement in fire resistance.
- Water Permeability: Rejuvenation revives the waterproof barrier, with tests showing a 97% decrease in water vapor permeability through aged shingles.
These are real performance gains that create a more resilient, longer-lasting roof.
Is Your Roof a Candidate? Key Signs for Rejuvenation
Asphalt shingle rejuvenation works best on roofs that are showing age but are not yet failing. Knowing the signs helps you act at the right time. Look for these indicators:
- Granule Loss: Finding coarse, sand-like granules in your gutters is a primary sign that your shingles are losing their protective layer.
- Curling or Lifting Edges: As shingles dry out, their edges may curl or lift, creating entry points for wind and rain.
- Brittle Texture: If shingles feel rigid or crack when gently bent, it means the essential oils have evaporated.
- Dark Streaks: Often caused by algae, these streaks can indicate that shingles are becoming more porous with age.
- Roof Age: The ideal window for rejuvenation is typically when a roof is 6 to 15 years old and showing these early signs.
These are your roof’s warning signs. Learn more in our guide: 5 Signs Your Roof Needs Rejuvenation.
When to Refresh Your Asphalt Shingles
Timing is key. The sweet spot for rejuvenation is when your roof shows early aging but is still structurally sound. This proactive approach is like changing your car’s oil before the engine seizes. By treating shingles between 6 and 15 years old, we intervene before minor issues become major damage, potentially adding up to 15 years to your roof’s life. Waiting until shingles are severely degraded means it’s likely too late for rejuvenation, and replacement becomes the only option.
Understanding the Limitations of Asphalt Shingle Rejuvenation
Rejuvenation is a powerful tool, but it’s not a cure-all. It restores the oils in your shingles but cannot fix existing physical or structural damage. Rejuvenation is not a solution for:
- Severely Curled or Brittle Shingles: If shingles are too far gone, they may not regain enough flexibility.
- Missing or Broken Shingles: These must be replaced before treatment. Our pre-treatment tune-up addresses this.
- Major Leaks or Structural Damage: Active leaks or rot in the roof deck require repair first.
- End-of-Life Roofs: Shingles that are completely worn out cannot be restored.
Our certified professionals conduct a thorough assessment to ensure your roof is a good candidate, providing an honest recommendation every time.
The Value of Rejuvenation: Cost, Convenience, and Sustainability
Asphalt shingle rejuvenation delivers value in three key areas: your wallet, your time, and the planet.
The Financial Advantage: Significant Cost Savings
The financial case for rejuvenation is compelling. A typical roof replacement in Michigan costs $20,000 to $30,000, while rejuvenation averages just $1,500 to $3,000. That’s a savings of up to 80%.
By extending your roof’s life by 5 to 15 years, you delay that massive replacement expense, keeping thousands of dollars in your pocket. This approach significantly reduces your total roofing costs over the life of your home.

The Convenience Factor: A Quick and Non-Disruptive Process
A roof replacement disrupts your life for days with noise, debris, and a dumpster in your driveway. In contrast, a rejuvenation treatment is completed in just 2 to 3 hours.
Our process is quiet, clean, and efficient. We protect your property, apply the treatment, and are gone before you know it. There’s no loud tearing of old shingles, no mess, and no stress. Any overspray of our gentle formula simply rinses away with water. It’s a “no mess, no fuss” approach that our Metro Detroit customers love.

The Sustainable Choice: Environmental Benefits
Each year, about 11 million tons of asphalt shingles are dumped in U.S. landfills. Rejuvenation keeps your existing shingles on your roof and out of the waste stream.
This choice also conserves the resources and energy needed to manufacture and transport new roofing materials, lowering your home’s carbon footprint. Our treatments support this goal, as many are USDA Certified Bio-Based products made from natural, food-grade oils. These non-toxic formulas are safe for your family, pets, and landscaping, making rejuvenation a truly green alternative.

The Rejuvenation Process: From Inspection to Protection
Our asphalt shingle rejuvenation service is a comprehensive, three-step process handled by certified professionals to ensure lasting results.
Step 1: Detailed Roof Assessment and Tune-Up
Every service begins with a thorough inspection. Our certified team examines your shingles for signs of aging like granule loss and brittleness, documenting any areas of concern. What sets us apart is that we then perform a complete roof tune-up. We address minor issues that could become major problems, such as caulking around vents, securing loose flashing, and fixing lifted shingles. This tune-up is essential, as rejuvenation works best on a sound roof. We’ll give you an honest assessment and only proceed if the treatment will provide real value.
Step 2: The Quick and Safe Treatment Application
After the tune-up, we apply the rejuvenation treatment. Using a specialized spray system, we ensure even coverage, allowing the bio-based formula to penetrate deep into the shingles. We carefully protect your landscaping, siding, and windows from overspray. Our 96% USDA Certified Bio-Based product is safe for people, pets, and plants, and any overspray rinses away with water. The entire application takes under three hours for most homes. The treatment penetrates within an hour, and in 72 hours, your roof’s flexibility and waterproofing are restored.
Step 3: Warranty and Long-Term Peace of Mind
We stand behind our work with a 5-year transferable warranty. This warranty covers the flexibility and granule adhesion of your treated shingles under normal conditions. If you sell your home, the warranty transfers to the new owner—a great selling point. The warranty ensures the treatment performs as promised. It does not cover pre-existing conditions or damage from severe weather events like major hail or hurricane-force winds. Our goal is to give you maximum value and peace of mind.
Frequently Asked Questions about Shingle Rejuvenation
Here are answers to the most common questions about asphalt shingle rejuvenation.
How long does a roof rejuvenation treatment last?
A single treatment extends your roof’s life by 5 years. The process can be repeated every 5 years, up to three times, potentially adding 15 years to your roof’s total lifespan. This allows you to delay a costly replacement while keeping your home protected.
Is the treatment safe for my family, pets, and plants?
Yes, absolutely. Our treatment is an all-natural, agricultural bio-oil formula, and many products are 96% USDA Certified Bio-Based. It is completely non-toxic and safe for people, pets, and property. Any overspray on your landscaping or driveway rinses away easily with water or the next rainfall.
Will rejuvenation void my roof’s original manufacturer warranty?
It’s highly unlikely. Most manufacturer warranties are heavily prorated and offer very little value by the time a roof is old enough for rejuvenation (6-15 years). Our treatment is a penetrating solution, not a coating, that restores the shingle’s original properties. Furthermore, we provide our own 5-year transferable warranty on the treatment’s performance, which often provides more meaningful protection than an aging manufacturer warranty. Proactive maintenance through rejuvenation can also be viewed favorably by insurance companies, potentially helping you maintain coverage.
