Silicone Asphalt Roof Coating
BUR Asphalt is “Built Up Roofing” and we coat it with Silicone every day!
Asphalt BUR is made up of multiple layers of reinforcing plies and asphalt, forming a redundancy of water resistant layers. The reflectivity of built-up roofs depends on the surfacing material used. Gravel is the most common, and they are referred to as asphalt and gravel roofs. Asphalt degradation is a serious concern. UV-rays oxidize the surface of the asphalt and produce a chalk-like residue. As plasticizers leach out of the built-up asphalt roofs become brittle. Cracking and alligatoring inevitably follow, allowing water to penetrate the system, causing blisters, cracks, and leaks. Compared to other systems, installation of asphalt roofs is energy-intensive (hot processes typically use LP gas as the heat source), and contributes to atmospheric air pollution (toxic, and green-house gases are expurged during installation).
Asphalt roofs are common, and we often see someone with a heated bucket of tar and a mop trying to stop leaks. Silicone Roof Coating over asphalt would solve your leaky asphalt roof issues. Contact us for more information and a free inspection of your asphalt roof.
About Asphalt Roofing
Asphalt is an aliphatic compound (hydrocarbon) and in almost all cases, a byproduct of the oil industry. Some asphalt is manufactured for roofing. Asphalt ages through photo-oxidation accelerated by heat. The more the heat, the faster it degrades. As it ages, the asphalts melting point rises, and there is a loss of plasticizers, meaning it gets brittle. As mass is lost, the asphalt shrinks and forms a surface similar to alligator skin. Asphalt also breaks down in water although this can take years. Asphalt dissolves easily when exposed to oils and some solvents.
Four Types of Roofing Asphalt
Type I asphalt has characteristics closest to coal tar and is used on dead level surfaces.
Type II is considered flat and can be applied to surfaces up to 1/4 in 12 slopes.
Type III is considered to be “steep” asphalt but is limited to slopes up to 2 in 12.
Type IV is “special steep.” It can be used up to a 5 in 12 pitch.
Advantages of using a silicone roofing system:
- Silicone is permanent and will not degrade, chalk or crack under harsh UV rays.
- Silicone forms a seamless membrane that withstands permanent ponding water without softening.
- Silicone creates a smooth surface that offers excellent resistance to mold, mildew, and staining.
