Built-up Roofing (BUR) has been with us for quite a long time now. We all know that it has always provided long-term performance for property owners. This, nonetheless, depends on a few simple industry rules, which sometimes get overlooked.
Fortenberry Roofing Co. adheres to these rules in all roofing projects. Your trusted commercial and residential roofing contractor reviews them here to help you get the most of your BUR.
Use the Right Asphalt
As always, it’s using the right material is key. ASTM D312 Type III and Type IV make up 95% of the hot asphalt used in roofing today. This is the standard specification for asphalt used in a built-up roof. Contractors consider both climate and roof slope when using D312 asphalt.
Use Only the Right Amount
The saying, “if a little is good, a lot must be better” does not apply to the construction of a built-up roof. Most manufacturers agree on the right amount of asphalt to use in a built-up roof. Too little asphalt means the finished membrane cannot keep water out. Too much of it and slippage of the plies and asphalt can occur. Fortenberry Roofing Co. is strict when it comes to abiding by these specifics. Your residential roofing company ensures a uniform and consistent application of the asphalt.
Be Mindful of EVT
“Equiviscous temperature” (EVT) helps in deciding on the right amount. Researchers also determined that there is a “best viscosity” for asphalt. When installed at this best viscosity, the amount will be approximately 25lbs per square. EVT also takes into consideration how the asphalt is being installed. Hand mopping specifies a viscosity of 125 centipoise, while mechanical spreader, 75 centipoise.
