Asphalt is a durable and widely used material for driveways, parking lots, and roads, but it’s not invincible. Over time, exposure to sunlight, rain, oil, chemicals, and heavy traffic wears it down. That’s where seal coating comes in. This protective layer shields your asphalt surface from damage, keeping it looking good and functioning well. But what happens if you delay it?
Today, we at Andersen Asphalt & Striping would like to take a look at the real risks of waiting too long to seal coat your asphalt.
Why is Asphalt Sealcoating Necessary?
1) Increased Surface Damage. Asphalt is made of aggregates (stone, sand, gravel) and a binding agent. Without seal coating, the sun’s UV rays gradually break down the binder, causing the surface to dry out and become brittle. This leads to cracks, potholes, and crumbling edges. If ignored, these small issues become major repair jobs, costing significantly more than preventative maintenance.
2) Water Infiltration. Cracks in unsealed asphalt allow water to seep into the base layer. Once water gets underneath the surface, it weakens the foundation, especially during freeze-thaw cycles in colder climates. This can lead to serious structural problems that compromise the integrity of the entire asphalt surface.
3) Stains and Oil Damage. Without the protective barrier of seal coating, your asphalt is vulnerable to staining from oil, gas, and other vehicle fluids. These chemicals can soften and weaken the asphalt, making it more prone to cracks and potholes. Seal coating helps resist these substances and makes cleanup easier.
4) Faded, Worn Appearance. Curb appeal matters, whether you’re a homeowner, property manager, or business owner. Asphalt that hasn’t been sealed in years will begin to look gray, patchy, and aged. A fresh seal coat restores that deep, rich black finish that gives a clean and well-maintained appearance to your property.
5) More Frequent & Costly Repairs. When seal coating is delayed too long, routine maintenance no longer cuts it. Instead, you may need to invest in crack filling, patching, or even full resurfacing or replacement. Seal coating every 2–3 years is a much more cost-effective way to protect your investment and extend the life of your asphalt.
6) Reduced Safety. Asphalt in poor condition poses safety risks. Cracks and uneven surfaces can become tripping hazards for pedestrians or damage tires and suspension systems for vehicles. For commercial properties, this could even result in liability issues.

Don’t wait until it’s too late. If your asphalt is showing signs of wear, like fading, cracks, or water pooling, it’s time to take action. Delaying seal coating only leads to more serious damage, higher repair costs, and shorter pavement life. Think of seal coating as insurance for your asphalt: a small investment now saves you from much bigger expenses later. If you’re unsure whether it’s time for a fresh seal coat, we’re here to help.
