A fiber mat includes a unitary assembly of fibers including at least a first set of fibers and at least a first binder comprising an organic resin, wherein the unitary assembly of fibers includes a minority portion and a majority portion different than the minority portion, wherein the fiber mat provides at least a 5% increase in tear when placed in a bituminous roofing product compared to an equivalent bituminous roofing product made with a fiber mat of equivalent weight containing a homogenous mat structure.

This invention, in embodiments, relates to a roofing material comprising (a) a coated or covered substrate and (b) a single sealant applied to a surface of the coated or covered substrate, with the single sealant being free of asphalt. The single sealant exhibits a minimum activation temperature (° C.) (tan δ>1) from −10° C. to 0° C. The single sealant is configured to adhere the roofing material to at least one of (i) an underlying roofing material, (ii) an overlying roofing material, and (iii) a roofing deck substrate.

A green roofing substrate brick comprises a water-permeable fabric box having an open top, and a solidified and non-compressed substrate in the box. The substrate comprises a water storage and drainage medium, and a binder solidifying the water storage and drainage medium.

A process for in-line extrusion of polymeric coatings onto roofing shingles during manufacturing includes moving a web of shingle substrate material in a downstream direction and extruding a liquefied coating of polymeric material onto at least one surface of the moving web to form a thin film. The liquefied coating may be a molten polymeric material that forms a thin film on a back surface of the shingle material to prevent sticking and eliminate the need for a traditional back dusting with material such as powdered stone. The polymeric film further may be applied to the substrate material in lieu of a saturation coating of asphalt, thus reducing cost and weight while providing a comparable moisture barrier and a lighter more flexible shingle.
