This section will cover the types of roofing tar you can consider for your building’s roofs.

Coal tar pitch

This type of roofing tar is formed when coal tar is exposed to a temperature of a higher degree; the resulting substance has a melting point of around 150 degrees Fahrenheit and is a dark brown or black substance when it comes to its color. While primarily used for the purposes of roofing, it can also be used for paving and the construction of drainage systems as well. Similar to other types of roofing tars, coal tar pitch is used to make the roofs more durable and weather resistant; its special features include providing resistance against oxidation, chemical attack and water damage. Generally speaking, coal tar pitch has a life of anywhere between 30 to 40 years which can be increased considerably with proper maintenance and regular inspection by professionals.

Coal tar bitumen

Coal tar bitumen is also known as type III tar and is actually a residual form which is often left behind after the distillation of petroleum. It is used to make the outer covering or the protective layer around the structure of the roof and is highly recommended to be used on the roofs which have a particularly steep slope. This type of roofing tar has a very high viscous temperature; it is the temperature at which coal tar bitumen attains its optimal viscosity or its maximum level thickness which is required for the purpose of roofing. It is a very stiff type of mixture and is sometimes referred to as steep asphalt by the people in the roofing industry. When it comes to the refining process, coal tar bitumen has to go through a longer process for getting refined as compared to coal tar pitch. However, even after going through this long refining process it is still more prone to be affected by the weather conditions, is less waterproof and is overall less durable than coal tar pitch which has a longer life and is more durable. It is owing to all these limitations that coal tar bitumen is often only used in buildings with steeper slopes or those which are located in hotter climatic areas.

Higher temperatures will make it difficult for it to set, while lower temperatures will make it harden and hence will make it difficult to use. Owing to its liquid/solid properties, the ideal temperature for roofing tar is around 70F. This liquid/solid property is what makes it an ideal product to use on flat roofs or roofs with a low slope. However, roofing tar is strictly not recommended to use of roofs with a higher slope, products with asphalt or products that have been thinned using water or other similar solvents.

It has been recommended by experts that homeowners who have a damaged roof or who may need to repair damages should consult with a professional to get over these jobs instead indulging in a do-it-yourself style project.
