An asphalt coated roofing shingle including a mat substrate saturated with asphalt, a top asphalt layer on a top surface of the mat, a bottom asphalt layer on a bottom surface of the mat, a granular layer on the top asphalt layer and a layer of melt-blown fibers applied to the bottom asphalt layer. A method for making a lightweight roofing shingle including the steps of saturating a mat substrate wherein the mat substrate has a top surface and a bottom surface; applying a top asphalt layer to the top surface; applying a bottom asphalt layer to the bottom surface; applying a layer of granular material to the top asphalt layer opposite the mat after the top asphalt layer is applied to the top surface; and applying a layer of melt-blown fibers directly to the bottom asphalt layer after the bottom asphalt layer is applied to the mat substrate.

A roof laminate (10) includes a roof membrane (12, 100, 200, 300) and a protective sheet (14, 114, 214, 314) removably affixed thereto. The surface (20) of the roof membrane (12, 100, 200, 300) can be protected from dirt, scratches and scrapes by a protective sheet (14, 114, 214, 314) which also provides other beneficial attributes that aid an installer. The membrane (12, 100, 200) and the sheet (14, 114, 214) are heat laminated together in the absence of adhesive and tackifiers. Alternatively, the membrane (12, 300) and the sheet (14, 314) are surface treated and then brought into contact with one another in the absence of adhesive and tackifiers. The sheet (14, 114, 214, 314)) may be single layer or include at least a first layer (30) directly secured to a second layer (32). The first layer (30) provides at least one of UV protection, anti-slip, and anti-glare to the roof laminate (10) and so aids the installer in at least one of those respects. The second layer (32) is removably affixed to the roof membrane (12, 100, 200, 300).

A fiber mat includes an assembly of fibers including a minority portion including a set of polymer fibers and a majority portion including a set of fibers different than the minority portion, wherein the minority portion is a plane parallel to a plane of the majority portion of the assembly of fibers; and a binder including an organic resin, wherein an air permeability of said fiber mat is not substantially different from an equivalent weight fiber mat containing a homogenous mat structure and 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 the equivalent weight fiber mat containing the homogenous mat structure.

Asphalt sealcoats and asphalt shingle waste coatings for roofing materials are provided. A roofing material comprises a substrate having an exposed surface and an unexposed surface. An asphalt shingle waste coating is located on at least a portion of the exposed surface of the substrate. The asphalt shingle waste coating comprises an asphalt shingle waste, wherein the asphalt shingle waste comprises a waste asphalt and a limestone. An asphalt sealcoat is located on at least a portion of the asphalt shingle waste coating. The asphalt sealcoat is substantially free of the asphalt shingle waste. The asphalt sealcoat has a thickness of no greater than 50% of a thickness of the asphalt shingle waste coating.

Some embodiments of the present disclosure relate to an roofing shingle comprising a low penetration point asphalt reinforced glass mat. In some embodiments, the reinforced glass mat comprises a glass mat and a reinforcement material. In some embodiments, the glass mat comprises a web of glass fibers. In some embodiments, the reinforcement material is embedded into the web of glass fibers of the glass mat. In some embodiments, the reinforced glass mat comprises a sufficient amount of the reinforcement material, so as to result in a nail shank shear resistance of 13 lbs to 17 lbs, according to ASTM 1761 at 140° F. Methods of making the roofing shingle and methods of forming a roofing shingle from the roofing shingle are also disclosed herein.

A shingle comprises an overlay, an underlay, and a height increasing material disposed between the overlay and the underlay. The height increasing material includes a first adhesive adhered to the overlay, height increasing granules adhered to the first adhesive, and a second adhesive adhered to the height increasing granules and the underlay. The height increasing material can extend along front ends of tab portions of the overlay, along front cutout edges that extend between tab portions of the overlay, or both.

A bituminous composition comprising at least one bitumen base, at least one compound of general formula (I): Ar1-R.sub.1—Ar.sub.2 (I), and at least one compound of general formula (II): R.sub.2—(NH).sub.nCONH—X—(NHCO).sub.p(NH).sub.n—R′.sub.2 (II). The invention also concerns a process for the preparation of said bituminous composition.

A method for generating a shingle roof coating is described. The method includes receiving an asphalt feedstock and separately proceeds to mix an elastomeric polymer and an asphalt flux to generate a first concentrate. The first concentrate is then heated separately from the asphalt feedstock. The method then mixes the first concentrate with the asphalt feedstock and heats the combined first concentrate and the asphalt feedstock to generate the shingle roof coating. The amount of elastomeric polymer in the first concentrate is adjusted based on the type of asphalt feedstock such that the resulting shingle roof coating includes 0.5% to 6% by weight of the elastomeric polymer.
