What is built up roofing and why are we hearing about it now? Build up roofing refers to the roof being built up over a time period of many years, often many decades. This is a building process, where layers of tar and gravel are poured onto the roofing structure and then allowed to sit and bond together over the course of many years. Once the layers of tar and gravel have been laid down and bond together, this is known as the tar layer. At this point, the surface of the roof is called the concrete layer.
If you have ever lived in an old style house, then you know that there will be areas of your home that will be moist and even damp during the entire year. During the summer months, these moist spots on your roof will collect debris from rain and continually seep into the ceiling and attic. Over time, this wet buildup will start to rot the wood and create unsightly water stains and mold. If you have any sort of decaying or damaged shingles on your roof, this is where the build up roofing comes into play. As the water and debris continue to sit, it will cause what is called flashing to appear across the roof line.
The tar and gravel layers that are used in asphalt shingles are the base for your new roof. After these layers are applied to the roof, they will be mixed with a type of binding agent to help keep the car in place. This agent, which is commonly referred to as granulated asphalt, is what makes your new roof last. It also adds additional strength to the roof so that the layers don’t break off.
As you can see, this process requires a little bit of building up before the tar and gravel are applied to the roof. When the tar is applied, this helps to level the roof. This also allows the builder to be able to make sure that all of the proper lint cutters have been used during the installation process. This ensures that no one should get a line on their building or home that goes over an existing tar line.
In order for a tar and gravel system to work properly, the tax must be applied to a level that is below the finished surface of the roof. When you first start to install your roof, you will need to make sure that this level is at or just below grade. Once this has been accomplished, you will then be able to create the proper flashing for the roof. This will help to provide the extra strength that is needed in order to support the heavier roof materials. This also prevents shingles from blowing off in strong winds.
