Different types of roof require different types of coating, so make sure you are applying the right type of coating for your roof by checking out the most common types of roof coatings below.

Caulk

Caulk is a type of roof coating that can be used on most roof toppings with crack and holes. Caulk is a popular roof coating because it’s cheap, easy to use and can be repeatedly replaced. Caulks must be applied using a caulking gun, and should never be applied when the roof is moist. You may have to wait for the roof to completely dry up before applying caulk to ensure a better seal.

Primers

This type of roof coating comes in different formulas, and is commonly used before painting the roof. One of the primary uses of primers for the roof is to help the paint adhere to the roof surface. Primers can also be used as sealants, but most variants have to be thoroughly dried before applying other kinds of sealants and coatings. The only notable drawback of primers is that it cannot be used on asphalt roofs.
