Asphalt surfaces, whether they are driveways, parking lots, or roads, are exposed to constant wear and tear from traffic, environmental factors, and weather conditions. Without proper protection, the lifespan of asphalt can be significantly shortened, leading to cracks, potholes, and costly repairs. One of the most effective ways to protect asphalt from harsh weather conditions is through sealcoating. This process involves applying a protective layer over the asphalt, which not only enhances its appearance but also extends its durability by shielding it from the damaging effects of weather. With this in mind, we at Andersen Asphalt & Striping would like to discuss how sealcoating protects asphalt from the more harsh weather conditions.
UV Rays & Sun Damage
One of the most destructive elements asphalt faces is sunlight. Over time, the sun’s ultraviolet (UV) rays can oxidize the asphalt, causing it to become dry, brittle, and more prone to cracking. This process accelerates the deterioration of the asphalt, turning a once smooth surface into a network of cracks and fissures. Sealcoating acts as a protective barrier, reflecting UV rays and slowing down the oxidation process. By doing so, it preserves the flexibility of the asphalt, preventing it from becoming brittle and less resistant to weather-related damage.
Rain & Water Penetration
Water is one of asphalt’s biggest enemies. When water seeps into cracks in the asphalt, it can weaken the underlying structure, causing it to break apart over time. This is especially problematic during freezing conditions when the water expands as it turns to ice, causing cracks to widen. Known as the freeze-thaw cycle, this process can create significant damage in colder climates. Sealcoating provides a waterproof layer that prevents water from penetrating the asphalt surface. By sealing small cracks and imperfections, it minimizes the risk of water infiltration, reducing the chances of damage from freezing and thawing.
Protection from Snow & Ice
In regions with harsh winters such as Northern Nevada, asphalt surfaces are subjected to snow and ice accumulation. As snow melts, water seeps into cracks, and when it refreezes, it causes the cracks to expand. Over time, this freeze-thaw cycle can lead to potholes and other surface damage. Sealcoating offers an additional layer of protection by reducing the asphalt’s exposure to moisture. Moreover, a well-sealed surface makes it easier to clear snow and ice, as sealcoated asphalt is smoother, reducing the adherence of ice and snow to the surface.
Oil & Chemical Resistance
In addition to natural weather conditions, asphalt is often exposed to oil, gas, and other chemicals that can degrade its surface. Vehicles frequently leak fluids that, when left unaddressed, can break down the asphalt’s binding agents. Sealcoating creates a protective layer that resists oil and chemical penetration, preventing them from weakening the asphalt and causing deterioration. This is particularly important for commercial parking lots and driveways with heavy traffic, where the risk of exposure to these substances is higher.
Temperature Fluctuations
Asphalt expands and contracts with changes in temperature. In areas that experience significant temperature fluctuations between day and night or between seasons, this constant movement can cause cracks and other forms of damage. Sealcoating helps to mitigate the effects of temperature changes by providing a flexible layer that moves with the asphalt, reducing the risk of cracking due to expansion and contraction.
Longevity & Cost Savings
Sealcoating doesn’t just protect asphalt from harsh weather; it also extends the life of the pavement. Regularly applying sealcoat can double or even triple the lifespan of an asphalt surface, saving property owners from costly repairs or premature replacement. The upfront cost of sealcoating is relatively low compared to the expenses of major repairs, making it a cost-effective solution for long-term maintenance.

Sealcoating is an essential step in asphalt maintenance, particularly for surfaces exposed to harsh weather conditions. By protecting against UV rays, water penetration, temperature fluctuations, and chemical exposure, sealcoating helps to preserve the integrity of asphalt, preventing cracks, potholes, and other forms of damage. For property owners looking to maintain their driveways, parking lots, or roads in top condition, regular sealcoating is a smart investment that pays off in durability, longevity, and reduced maintenance costs.
