A roofing shingle having a fire-retardant material added to the shingle in specific locations is provided. In one aspect a roofing system with two or more asphalt-coated substrates and a sealant material provided between the substrates is provided. The sealant material adheres an overlying and underlying shingle together and can contain a fire-retardant material. In a second aspect of the present invention, a multi-layer laminated shingle is provided with an adhesive material between one or more asphalt-coated substrates which adheres the asphalt-coated substrates together and can contain a fire-retardant material.

Asphalt shingles with a fire-retardant additive

A method of manufacturing a roofing shingle includes applying an asphalt coating to a substrate to define an asphalt coated sheet, the asphalt coated sheet including a headlap portion and a tab portion. Reinforcement material is appliedfrom a spoolto the asphalt coated sheet, wherein the reinforcement material iswound in a waywind pattern on the spoolpayed out from a roll. The reinforcement material is then secured to the headlap portion of the asphalt coated sheet.Prior to applying the reinforcement material to the asphalt coated sheet, the reinforcement material has a first width. The method further includes shrinking the reinforcement material to a second width narrower than the first width upon securing the reinforcement material to the headlap portion.
