How Climate Affects Roof Performance and Longevity
How Climate Affects Roof Performance and Longevity By Russell Beckum, Roofing Systems & Performance Specialist Earlier this month, several regions across the United States experienced severe hailstorms, damaging winds, and tornado outbreaks that left thousands of homeowners dealing with roof damage, fallen debris, and emergency repairs. Events like these serve as a reminder that climate is not just a background factor in roofing performance, it is one of the most powerful forces affecting how long a roof lasts and how well it protects a home. An asphalt shingle roof in the dry desert heat of Arizona ages differently than a roof exposed to the humidity and hurricane conditions common in Florida. Homes in Colorado may face repeated hail impacts, while northern states deal with freeze-thaw cycles and ice buildup throughout winter. Every climate creates a unique form of stress on roofing systems. From a roofing systems perspective, roofs do not deteriorate based on age alone. They respond continuously to environmental conditions such as heat, moisture, ultraviolet exposure, storms, and temperature fluctuations. Over time, these conditions influence how roofing materials expand, contract, retain flexibility, and resist deterioration. At Roof Savers®, understanding climate-related stress is essential when evaluating roof performance and longevity. A roofing system is always reacting to its environment. During hot afternoons, roofing materials expand. At night, cooler temperatures cause contraction. Rain introduces moisture stress, while prolonged UV exposure gradually weakens material composition. This cycle repeats every single day. Over years of exposure, these environmental reactions accumulate and slowly affect roof performance. While a roof may still appear functional from the ground, internal deterioration can already be taking place. Climate should never be treated as a secondary consideration. It directly influences the lifespan and durability of roofing materials. In warmer regions throughout North America, prolonged heat and sunlight create significant stress on asphalt shingles. Ultraviolet radiation slowly breaks down the protective structure of roofing materials through oxidation. As shingles lose flexibility, they become increasingly brittle and vulnerable to cracking. Heat also intensifies thermal movement. Roofing materials repeatedly expand during the day and contract at night, creating long-term mechanical stress that contributes to surface fatigue, granule loss, sealant breakdown, and structural weakening. States such as Arizona, Texas, and parts of Nevada experience some of the highest levels of UV exposure in the country, which can accelerate roof aging considerably faster than cooler climates. Recent hailstorms across parts of the Midwest and South have highlighted another major climate factor affecting roof performance, impact damage. Large hail can weaken asphalt shingles by dislodging protective granules and creating hidden fractures that may not be immediately visible. Strong winds associated with tornadoes and severe storms can lift shingles, loosen flashing, and expose vulnerable sections of the roof system. What makes storm damage particularly dangerous is that it often goes unnoticed at first. A roof may appear fine after a storm, but small vulnerabilities created by hail or wind can eventually lead to leaks and accelerated deterioration. This is why post-storm inspections are critical, especially after major weather events. In northern states, roofing systems experience an entirely different type of stress due to freezing temperatures and snow accumulation. When moisture enters small cracks or vulnerable areas and freezes, it expands. This expansion gradually widens weak points and places pressure on roofing materials. Ice dams are another common issue in colder climates. Improper ventilation can cause snow to melt unevenly and refreeze near roof edges, trapping water beneath shingles. Cold temperatures also reduce material flexibility, making shingles more vulnerable to cracking during freeze-thaw cycles. In humid regions like Florida and the Carolinas, moisture becomes one of the primary factors affecting roof performance. High humidity levels can contribute to algae growth, prolonged surface dampness, and accelerated material wear. Coastal environments also expose roofs to salt-laden air, which can increase corrosion on metal roofing components and fasteners. Moisture management is essential in these climates because trapped moisture gradually weakens roofing systems from both the exterior and interior. One of the most overlooked aspects of roof care is adapting maintenance to local climate conditions. A roof exposed to intense UV radiation requires different preservation considerations than one exposed to hailstorms or coastal humidity. Roofing systems should be evaluated based on how environmental conditions affect their specific performance characteristics. This includes: A proactive approach allows homeowners to address climate-related wear before structural issues develop. Because environmental exposure accelerates roof deterioration, preservation becomes increasingly important in climates with severe weather conditions. Preservation treatments such as Renueit17® are designed to support asphalt shingle performance by improving flexibility and helping maintain granule stability. When applied at the appropriate stage of roof aging, Renueit17® can extend the life of an asphalt shingle roof by 17 additional years. Preservation is about maintaining performance under ongoing climate exposure, not simply improving appearance. Climate plays a major role in determining how roofing systems age and perform over time. Heat, hailstorms, tornadoes, moisture, freezing temperatures, and UV exposure all contribute to long-term roof deterioration in different ways. Understanding how local weather patterns affect roofing materials allows homeowners to make smarter decisions about inspections, maintenance, and preservation. Through regular evaluations and preservation strategies from Roof Savers®, homeowners can better protect their roofs against the long-term impact of environmental stress while maximizing roof lifespan. Comparing Roof Preservation Technologies: Understanding the Different Approaches to Roof Longevity By Scott, Roofing Systems & Technical Insights For decades, the roofing industry has largely focused on one outcome when asphalt shingles begin to age, replacement. Once signs of wear appear, homeowners are often told the roof has reached the end of its useful life. However, advances in roof preservation technologies are changing that conversation. Today, preservation solutions are designed to extend roof performance, reduce premature replacement, and improve long-term system efficiency. But not all preservation technologies work the same way. Different formulations, application methods, and performance goals create significant differences in how these systems interact with roofing materials. At Roof Savers®, the emphasis is on understanding roofing systems scientifically and selecting preservation strategies that support long-term durability rather than temporary cosmetic improvements. This article compares modern roof preservation technologies and explains how different approaches affect asphalt shingle performance and roof lifespan. Traditional roofing philosophy often treated aging as irreversible. Once shingles showed signs of brittleness, granule loss, or discoloration, replacement became the standard recommendation. However, roofing systems do not typically fail all at once. In many cases, structural integrity remains intact while material performance gradually declines. Preservation technologies are designed to intervene during this stage by restoring or maintaining critical performance characteristics. The goal is not to make an old roof appear new. The goal is to extend functional lifespan while maintaining protection and durability. Modern preservation systems generally fall into several categories, each with different technical approaches. Some technologies focus primarily on surface coatings. Others are designed to improve flexibility, reinforce material stability, or reduce environmental degradation. The effectiveness of each system depends on how it interacts with the roofing material and whether it addresses the underlying causes of aging. Some early roof treatment technologies relied on oil-based or penetrating formulations designed to soak into asphalt shingles. These systems aimed to restore flexibility by reintroducing oils into aging materials. The theory behind these technologies was that as shingles aged and dried out, replenishing lost oils could improve flexibility and reduce brittleness. While these treatments may temporarily alter material characteristics, they do not always address broader system-level concerns such as granule retention or long-term environmental durability. Additionally, penetration-based approaches can vary significantly depending on roof condition, weather exposure, and material composition. Another category of preservation technology focuses on stabilizing the outer surface of asphalt shingles. These systems prioritize maintaining granule adhesion and preserving the protective outer layer of the roof. Granules play a critical role in shielding shingles from ultraviolet radiation and environmental wear. Once granules begin detaching, deterioration accelerates rapidly. From a systems perspective, preserving surface integrity is essential because it directly affects how well roofing materials resist UV exposure, moisture, and thermal stress. More advanced preservation technologies now utilize water-based polymer formulations. These systems are designed to improve flexibility, reinforce material stability, and support long-term performance without relying on oil-based penetration methods. Renueit17® is an example of this type of preservation technology. Unlike oil-based treatments, it uses a water-based polymer formulation engineered to support asphalt shingle performance while helping maintain granule adhesion and material flexibility. This approach focuses on preserving the structural behavior of roofing materials rather than simply altering surface appearance. When applied at the appropriate stage of roof aging, Renueit17® can extend the life of an asphalt shingle roof by 17 additional years. One of the most overlooked aspects of roof preservation is granule retention. Granules serve as the roof’s primary defense against ultraviolet radiation and environmental exposure. Once granules begin washing into gutters or collecting around downspouts, the asphalt layer beneath becomes increasingly vulnerable. Some preservation systems focus heavily on restoring appearance, while others prioritize protecting the functional outer surface. From a performance standpoint, maintaining granule stability is one of the most important factors in extending roof lifespan. Roof preservation technologies are built around a fundamentally different philosophy than roof replacement. Replacement removes existing materials and starts over completely. Preservation, on the other hand, seeks to optimize the remaining life of the current roofing system. From a lifecycle management perspective, preservation can reduce material waste, lower costs, and delay replacement until it is structurally necessary. This does not mean preservation is appropriate for every roof. Severely damaged or structurally compromised systems may still require replacement. However, many aging roofs remain viable candidates for preservation long before replacement becomes necessary. When comparing preservation technologies, homeowners should consider more than immediate visual results. Long-term performance depends on several factors, including: A preservation system should support the overall roofing structure, not simply provide a short-term cosmetic improvement. No preservation technology should be applied without first evaluating the condition of the roofing system. Proper inspections help determine whether the roof remains structurally sound and whether preservation can provide meaningful lifespan extension. At Roof Savers®, roof evaluations focus on performance indicators rather than age alone. The condition of the shingles, granule retention, flexibility, and overall system integrity all play a role in determining whether preservation is appropriate. Roof preservation technologies continue to evolve as the roofing industry moves toward more sustainable and performance-driven solutions. While different technologies use different methods, the core objective remains the same, extending roof life while maintaining protection and durability. Understanding the differences between oil-based systems, surface stabilization methods, and water-based polymer technologies helps homeowners make informed decisions about long-term roof care. With preservation solutions like Renueit17® and system-focused strategies from Roof Savers®, homeowners now have more options to maximize the lifespan of their asphalt shingle roofs before considering replacement.

Allen Childs is widely recognized for his expertise in roof preservation and lifecycle extension.
As a leading voice behind Roof Savers®, he focuses on helping homeowners understand that
roof replacement is not always the only option. In this interview with Morning Mix, Allen explains
how modern preservation methods, including the use of Renueit17®, can restore aging roofs,
extend their lifespan, and significantly reduce costs.
Welcome back to Morning Mix. Your roof is one of the most important parts of your home, but
it's also one of the most expensive to replace. Now there may be another option that helps
extend the life of your roof and save you money along the way. Today, we're talking about roof
preservation and how it works. Joining us now is Allen Childs. He is the owner of Roof Savers®.
Allen, good to see you.
Good to see you, too.
For people who may not be familiar with this, which I kind of doubt, because you're on TV
everywhere. What is Roof Savers®? What services do you guys offer for this?
So our main focus is on roof preservation. We can take asphalt shingles that are a little bit older,
dry and brittle, and we can preserve them, giving a homeowner an additional 17 years of life
with just one application. Our product is patent pending. There's nothing like it on the market
today, but it also has multi-surface applications. We can do vinyl siding, Hardie board, stucco,
as well as asphalt shingles, and even metal roofs.
Wow, you're really bringing things literally back to life.
Yeah, and when you look at the cost of materials and labor today, everything is expensive. So
why not take care of something that you already own instead of replacing it?
Absolutely. So what exactly is roof preservation? If you could break that down for us, and how
does it work?
When an asphalt shingle gets older, it becomes dry and brittle. You might notice granules in
your driveway or gutters when you're cleaning them out. That’s actually your roof aging. What
we do with roof preservation is use a patent-pending product called Renueit17®. We lock down
those granules to keep them on the roof, extend the life of the roof, and bring back flexibility.
Wow, look at those before and after pictures. That’s amazing work.
Yeah, it really is. And like I mentioned, it’s not just for roofs. We also have another product
called Renueit Wood Armor. It helps preserve wood, so instead of re-staining every year, you
can get an extra 5 to 10 years with one application.
What makes this Renueit17® product different from other options out there?
So there's the original formulation. It's called soy methylester. a plant-based product, and it
basically works a little bit differently where it penetrates the shingles and goes in, they're
supposedly bringing back the flexibilities. We're concentrating more on keeping the granules on
the shingles. You keep the granules on the shingles, you keep the roof on the house longer.
So how much can a homeowner save compared to a full roof replacement?
Up to 75 percent. It depends on the size of the home, but most homeowners see around 70
percent savings.
That’s a big difference. So walk us through the process. What does it look like from start to
finish?
We start with a free roof inspection. We get on the roof, take photos, and determine if it
qualifies. If it does, we come back for a three-step process over two visits. First, we do a roof
tune-up by securing loose shingles, replacing missing ones, and sealing flashing areas. Next,
we soft wash the roof to remove algae and buildup. Then about a week later, we apply the
Renueit17® treatment. Once completed, the homeowner receives a 17-year transferable
warranty.
That transferable warranty is a great benefit.
Yes, it adds real value, especially for homeowners thinking long term.
For viewers interested in learning more, where can they go?
Visit our website at myroofsavers.com. You’ll find more information about what we do, and you’ll
also see our national spokesperson, Larry Mize, a former Masters champion. We actually
treated his father’s roof, and he was so impressed he decided to work with us.
That says a lot. Allen Childs, great to see you.
Great to see you too. Thank you.
thinking to preservation-focused solutions. With innovations like Renueit17®, homeowners now
have the opportunity to extend the life of their asphalt shingle roofs by 17 years while saving
significantly on costs.
