Abstract
In a method of reducing voids in an asphalt roofing product, an asphalt coating material having voids is contacted with a vacuum in an amount effective to reduce the voids in the coating material. A mat is coated with the coating material to make an asphalt roofing product. The vacuum contacting step occurs prior to the coating step. The vacuum contacting step causes the roofing product to have reduced voids visible on a top surface compared to the same roofing product made with a coating material not contacted with vacuum.
