Many people don’t quite understand the difference between asphalt overlay and asphalt sealcoat, which is understandable; they have similar processes that are both used to upgrade and maintain your asphalt.
So what is asphalt overlay? Basically, it is a patch job done on your asphalt. An overlay is typically done when you start seeing cracking or potholes forming on your asphalt, but not damaged enough to need a full replacement. This process is done by coming through with a paver and laying a thin layer of hot asphalt on the current surface. This, however, is not a permanent fix for underlying issues. Any cracks you have on your asphalt now will eventually show through the overlay in a year or two.
Sealcoating, on the other hand, fills shallow cracks and should be done on larger cracks in order to prevent water from penetrating the underlying asphalt. This process is a lot like re-painting your home. In the end, they both turn out with a shiny surface, discourages wear and tear, keeps water or spills out of the interior and protects against harsh weather. However, unlike painting your home, the sealcoating wears out quickly. If you invest in an easy crackfill and sealcoat about every 2-4 years you can typically prevent other maintenance for a period of time.
