Asphalt sealcoating is the process of adding or replacing a protective top layer to your asphalt driveway or parking lot in order to prevent many types of damage. Unfortunately, many people do not know how to spot the signs that it is time to sealcoat their asphalt surfaces. This can lead to a variety of different types of damage and may even result in the need for a whole new piece of asphalt to be poured. Thankfully, taking the time to look out for the three signs described below can help you to avoid finding yourself in this same position. 

#1: Faded Color

Asphalt sealcoating not only helps to protect your driveway or parking lot from damage, but it also helps to contribute to its cosmetic appeal. This is because sealcoating your asphalt will prevent this surface from becoming faded as a result of exposure to UV rays. This allows you to maintain the deep black color that makes asphalt such a great aesthetic choice. If you notice that your asphalt is starting to take on a faded gray color, this is a good indication that it is time to have your asphalt sealcoated. 

#2: Poor Drainage

The protective layer provided by asphalt sealcoating helps to prevent liquids from seeping deep into the asphalt. This is very important since high moisture content can result in potholes and large cracks as the liquid expands and contracts in reaction to outside temperatures. Some substances such as motor oil can also leave behind dark stains on your asphalt if these liquids are allowed to seep below the surface. If you notice staining or puddles on your driveway, this is an indication that moisture is no longer being effectively drained away from your asphalt. Having your asphalt sealed will restore proper drainage and allow you to avoid damage. 

#3: Alligator Cracks

There are several different types of cracks that can develop in your asphalt over the years. Alligator cracks get their name from the fact that they closely resemble the pattern of alligator skin. This particular type of cracking is most often related to a top layer that has worn off leaving the underlying asphalt exposed to the elements. If you notice this type of cracks in your asphalt, simply filling them in will not be enough to prevent future damage. In order to accomplish this goal, you will both need to fill the cracks and have your asphalt sealed.
