The invention provides a bright white refractory roofing granule, comprising a ceramic material formed from a substantially homogenous mixture of a ceramic-forming clay, sintering material, and optionally comprising silica particles, and other potential additives, said bright white refractory roofing granule having a total solar reflectance of at least 0.80 and a Hunter Color Lvalue of at least 85.0, together with processes for making and using the same.

Roofing granules having a color coating layer are covered with a clear, transparent or translucent outer coating composition including a functional material, such nanoparticles of anatase titanium dioxide.

Solar reflective roofing granules include a binder and inert mineral particles, with solar reflective particles dispersed in the binder. An agglomeration process preferentially disposes the solar reflective particles at a desired depth within or beneath the surface of the granules.

A tufted geosynthetic lightweight ballast system for roof protection in which the system comprises a composite of one or more geotextiles tufted with one or more synthetic yarns.

Some embodiments of the present disclosure relate to methods and roofing systems including a hybrid layered structure. In some embodiments, the hybrid layered layer structure, method, and system are used for waterproofing at least one steep slope roof substrate. In some embodiments, the at least one steep slope roof substrate at least one protruding member protruding from the at least one steep slope roof substrate. In some embodiments, the hybrid layered structure comprises a first coating layer, a roofing membrane, and a second coating layer.

A roofing formulation may comprise a first part and a second part. The first part may comprise a coating material, the coating material comprising at least one acrylic latex resin, at least one functional filler, and at least one hydrophobic additive. The second part may comprise an activator formulation. The roofing formulation may be applied as a coating to a roofing substrate. A roofing system may comprise at least one roof substrate and a multi-layer coating system. The multi-layer coating system may comprise at least one top layer and at least one core layer disposed between the at least one top layer and the at least one roof substrate.

A two component roof coating system and method includes a sufficiently porous fabric attachable to a roof deck. A first component of the two component roof coating may be applied to the fabric after it is attached to the roof. Alternatively, fabric may be pre-soaked with the first component prior to attachment. A second component of the two component roof coating may then be applied to the fabric. The first and second components react with each other to form a waterproof roof coating. The fabric can hold the components in place and prevent sagging.

Fastener systems for roofing systems are disclosed for fastening a fabric, mesh, or base sheet to a roof deck prior to application of a liquid applied roof coating. The fastening assemblies may be attached to an uncleaned or unprimed roof deck and a fabric is laid atop the fasteners. The fasteners secure the fabric using mechanical binding or chemical bonding without penetrating or dimpling the fabric.
