Since the main reason behind the use of roofing tar is to enhance the durability of the roof and protect it from the affects of weather and other natural factors.
What is roofing tar made of?
Roofing tar is actually an oily mixture with a dark color which is used to fix any leakages or gaps on flat roofs. The main elements used in its formation are mostly petroleum and coal tar byproducts. During the process of coal production a dark brown or black residue is left behind which is called as coal tar. When this dark substance is refined keeping in mind the standards which have been set for use in the process of roofing, the product formed is called roofing tar.
Since roofing tar is a refined form of coal tar, it is important that readers first come to terms with what exactly coal tar. Coal tar is a substance which is used to repair any damages or leakages on flat roofs as it has amazing properties of sealing and repairing areas which are deteriorating. Many formulations of coal tar include solvents, mineral fibers, surface adherents or plastic fillers. However, most of the newer formulations of this sticky substance are asbestos free. When it comes to coal tar, users need to make sure that it has be applied by trowel, unlike other varieties of roofing tars which can be applied on the areas that need repair simply as caulk or paint.
While most formulas of roofing tars are very dark brown or black in colors, however newer varieties are also available in white or silvers tones. Also, if the actual damage was in a visible area which may look unsightly with black roofing tar, you can paint most varieties of roofing tar after they have dried. You can paint over dried up roofing tar so the area matches the color of the surroundings and does not affect the ambiance of the room with its dark color. In addition to this, you can also remove any access roofing tar by a specially designed tar remover but on the downside it can cause some damage to a certain type of roofing surfaces.

Roofing tar is one of the most extensively used products when it comes to the construction of a roof in a building as it makes it more durable and weather resistant than anything. Tar is formed by destructive distillation of roots and trees and is an ages old formula to enhance the life of roofs be it residential or commercial buildings or even boats and ships.
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. To take proper care of your roof you need to make sure that the materials which are ever used in case of a repair job are compatible with the original materials used in the construction of the roof. Also, record keeping of any repair jobs done over time will help you in ensuring proper maintenance of your roof.
Asphalt roofing tar
When it comes to Asphalt roofing tar, it is recommended to be used in built-up roofing, roof shingles and roll roofing. Asphalt shingles come in a wide range of varieties including individual pieces which can either be rectangular or hexagonal, interlocking to enhance their resistance to wind, laminated as thick tiles made of asphalt or in strips. If you are considering roll roofing products you can easily find them in varieties like saturated felt, mineral surfaced, specialty eaves-flashings or smooth surfaced. Roll roofing products are primarily used in residential buildings instead of commercial buildings. On the other hand are built up roofing also known as BUR which is most commonly used in industrial, commercial or institutional structures.
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.
What are the uses of roofing tar?
Before we begin about what are the uses of roofing tar, you need to keep in mind that it is important to pick out right variety of roofing tar as they come in a very wide range of brands and formulations so you need to pick out the best product for use very carefully.

Ideal temperature for roofing tar
Temperature is a critical aspect when it comes to the perfect setting of roofing tar. 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. Using roofing tar in a wrong manner or walking over the area which has fresh roofing tar on can lead to disastrous consequences and is better avoided. So, if you have a damage repair issue of any major or minor type it is always better to immediately consult a professional you can trust.
Since it is very tricky product to use, experts recommend that homeowners always consult professional services for any damage repair jobs to avoid any more disasters. It is very important that the roofs of buildings in particular are of a very good quality as any damage caused to them can directly affect the quality of construction of the entire building.
