The present disclosure relates to roofing materials with patterned adhesives and methods for applying the patterned adhesives.
Traditional roofing materials have adhesives for attaching the roofing materials to other roofing materials and/or roofing substrates. Adhesives are typically applied to a roofing material in a two-step process. First, the roofing material may be manufactured in a factory. Then an adhesive may be applied to the back of the roofing membrane. After the adhesive cures, the roofing material may be adhered to another roofing material and/or to a roofing substrate.
