The Science Behind Roof Preservation Treatments
By Allen Childs, Roof Preservation Systems
When homeowners hear the word chemistry, they often imagine a laboratory filled with test tubes and complex formulas. But chemistry plays a much bigger role in everyday life than most people realize. Every time you paint a wall, stain a deck, wash your driveway, or protect your roof, chemistry is at work.
The same is true for roof preservation.
Over the years, I've had many homeowners ask me, "What exactly are you putting on my roof?" It's a fair question. If you're investing in protecting one of the most valuable parts of your home, you deserve to understand how the treatment works and why it's different from other products on the market.
Roof preservation isn't about covering up problems or making an old roof look newer for a few months. It's about applying proven science to help aging roofing materials continue performing the job they were designed to do.
At Roof Savers®, we believe homeowners should understand the science behind preservation just as much as the results.
Every Roof Changes at the Molecular Level
An asphalt shingle roof doesn't suddenly become old overnight. Aging happens slowly through thousands of days of exposure to sunlight, rain, wind, temperature swings, and airborne contaminants.
As these environmental conditions continue year after year, the physical properties of the shingles begin to change. The surface becomes more vulnerable, flexibility decreases, and the protective layer gradually weakens.
These changes are part of a natural chemical aging process. The goal of roof preservation is to interrupt that process before deterioration reaches the point where replacement becomes the only option.
That's where preservation chemistry becomes important.
Preservation Is More Than Cleaning a Roof
One misconception I hear is that roof preservation is simply roof cleaning.
Cleaning is certainly an important first step, but it is only the beginning.
Before any preservation treatment is applied, the roof must first be properly prepared. That means removing oxidation, mold, algae, dirt, and other contaminants that have accumulated over time.
Think of it like painting a wall. You wouldn't paint over peeling paint and expect lasting results. The surface has to be properly prepared before any protective treatment can bond effectively.
At Roof Savers®, every qualifying roof undergoes this preparation process before Renueit®17 is applied. A clean surface allows the preservation technology to perform as intended.
Different Preservation Technologies Use Different Chemistry
Not all roof preservation products are designed the same way.
For many years, some preservation systems have relied on bio-based oil formulations, such as soy methyl ester. These products are designed to penetrate asphalt shingles with the goal of improving flexibility.
That approach has been available in the industry for some time.
Our philosophy is different.
Rather than concentrating only on penetration, Renueit®17 focuses on preserving one of the roof's most valuable protective assets, its granules.
I've often explained it this way:
If you keep the granules on the shingles, you keep the roof on the house longer.
Those granules aren't simply decorative. They shield the asphalt beneath from ultraviolet radiation, weather exposure, and environmental stress. Once granules begin washing into gutters or collecting in driveways, the aging process accelerates.
Preserving that protective layer is one of the most important parts of extending roof life.
Renueit®17 is not an oil-based treatment.
It is a patent-pending water-based polymer roof preservation treatment that incorporates proprietary MicroCrazeVR™ and RocLoc™ Technologies. These technologies were developed to support the long-term performance of asphalt shingle roofs while helping maintain granule adhesion and improve material flexibility.
Unlike products that require repeated applications over time, Renueit®17 is designed as a one-time preservation treatment. When applied to a qualifying asphalt shingle roof, it has been lab tested and proven to add 17 additional years of life with a single application.
That difference is significant for homeowners. Rather than scheduling multiple treatments over many years, a single preservation application can deliver long-term protection while reducing both cost and disruption.
Why One Application Matters
One question I hear frequently is why one application is enough.
The answer lies in the chemistry of the formulation itself.
Renueit®17 was engineered to create long-lasting protection rather than temporary surface improvement. Once properly applied to a prepared roof, the treatment works with the existing roofing materials to help preserve their performance over time.
Some competing preservation systems recommend multiple applications over the course of fifteen years to achieve their expected lifespan.
Our approach is different.
One properly prepared roof.
One professionally applied treatment.
One preservation strategy focused on extending roof life by 17 additional years.
For homeowners, that means fewer service visits, lower long-term costs, and less interruption.
Preservation Benefits Beyond the Roof
The chemistry behind preservation also supports something larger than roof performance.
Every year, millions of tons of roofing materials end up in landfills, even though many roofs still have years of useful life remaining.
When preservation can safely extend the lifespan of a qualifying roof, homeowners reduce construction waste while avoiding premature replacement.
That's good for the homeowner's budget, and it's a more environmentally responsible approach to maintaining a home.
The same preservation philosophy extends beyond asphalt shingles. Renueit® technology can also restore and preserve vinyl siding, cedar shake, Hardie® Board, stucco, tile, wood, and metal surfaces, helping improve appearance while extending service life.
Preservation Starts with Timing
One of the biggest mistakes homeowners make is waiting too long.
Once severe structural deterioration has occurred, preservation is no longer the appropriate solution. That's why regular inspections are so important.
The best candidates for preservation are roofs that are aging but still structurally sound.
Taking action early gives homeowners more options and helps avoid emergency repairs that often cost significantly more than preventative care.
The chemistry behind roof preservation isn't about creating a cosmetic improvement. It's about using modern material science to slow the natural aging process and help roofing systems continue performing as intended.
At Roof Savers®, our preservation philosophy is built on proven technology, thoughtful preparation, and long-term performance. Renueit®17 focuses on preserving the roof's protective granules, because those granules are essential to the longevity of an asphalt shingle roof.
When applied at the right stage of a roof's life, preservation isn't simply an alternative to replacement. It's a smarter way to protect your investment, reduce unnecessary waste, and keep your roof performing for years to come.
