When roofing tar is applied to the roof, it seems to be somewhat in a liquid stage. After a certain period of time, the roofing tar tends to harden up or bond a firm layer on your rooftop.

The curing process also can be calculated on temperature, types of tar used, and weather conditions.

If the weather is dewy, snowy, or rainy, do not start the process of tarring. Because in such a situation, the humidity of the weather remains high. Thus, the curing becomes slower and the roof becomes all messy and sticky.
