First, let’s take a quick look at the difference between overlays and sealcoats Asking for one when you require the other could lead to extra costs further down the road.
No pun intended.
An asphalt overlay is one or more layers of fresh asphalt that is installed over an existing pavement, more commonly known as resurfacing. This is the usual method when asphalt is showing some cracking or potholing, but not quite damaged enough to require a full replacement. The overlay surface appears to be new or rebuilt pavement, but they are far less expensive and faster to install.
An asphalt sealcoat is a protective coating that discourages wear, as well as preventing sun damage and interior water damage. While a good sealcoat can generally fill extremely shallow cracks, crackfilling should be done on larger cracks to prevent any water from penetrating the interior of your asphalt. A sealcoat is not recommended for major repairs, but rather, to prevent major repairs from being required.
Though sealcoating wears out relatively quickly, routine sealcoat applications and crackfill maintenance every 2-4 years can usually prevent other major asphalt maintenance for years to come. This is the most cost-effective way of maintaining asphalt over long periods of time.
