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.

A roofing board, such as a polyiso insulation board, includes first and second surfaces, where the first surface is lighter in color than the second surface. This allows the roofing installer to choose which of the surfaces to expose to the atmosphere, the lighter surface being cooler than the darker surface. The lighter surface may have a solar reflectance greater than the darker surface. A roofing membrane is then adhered or otherwise attached to the exposed surface.

An integrated roofing product comprising a wood or cellulosic structural or roof sheathing base or core panel with a rigid foam insulation sheet or layer laminated or otherwise attached to the panel's inner face. Shingles and/or other protective material may then be attached to the panel's outer face. A plurality of parallel air channels extend vertically in the rigid foam insulation sheet or layer, providing a pathway for air to pass up and out of the eave space. Some or all of the air channels are disposed on the surface of the foam layer that is laminated or attached to the panel's inner face, so that part of the air channel is formed at the interface. A radiant barrier layer may be placed on the inner face of the rigid foam insulation sheet or layer, or between the foam insulation and the inner face of the roof sheathing base or core panel.

A roof system includes a roof deck, a weighted cover board disposed upwardly adjacent the roof deck and a plurality of fasteners coupling the weighted cover board to the roof deck.

The panel includes a water resistant barrier layer secured atop its outward facing surface. The water resistant barrier layer includes a skid resistant surface. The panels are made of lignocellulosic material. The water resistant and skid resistant surface may include indicia for aligning strips of tape or for aligning fasteners. A method for manufacturing the water resistant building panels is also disclosed and includes the steps of feeding paper onto a forming belt, depositing lignocellulosic material and the binding agent onto the forming belt so as to form a lignocellulosic mat, applying heat and pressure so as to impart the skid resistant surface on the paper, and cutting panels to predetermined sizes.

A roofing system with interlocking structural panels that have an outer, exterior side surface adapted to be exposed to weather, and an inner side that faces the interior of a structure when installed. The roofing system generally can include a first plurality of structural panels and a second plurality of structural panels, with at least one of the pluralities of structural panels including roofing panels, and the other plurality of structural panels including photovoltaic modules or solar panels that can be mounted in series with the roofing panels to form the roof structure. The structural panels of the roofing system are configured to act as structural components for construction of a roof structure, and are further adapted and/or constructed to be easily handled and installed by individual installers.

A hook and loop system for attaching a roofing membrane into the top of a building insulation board including a roofing membrane with a fleece backing having a release sheet on the fleece backing. The release sheet is manually removed in the field to attach the fleece backing directly onto a layer of hooks that have been pre-attached onto the top of the insulation board. The release layer may be somewhat sticky, yet not adhere too tightly to the fleece layer such that its removal does not damage the fleece backing. The release layer may also be pre-rolled together with the fleece backed roofing membrane and shipped together as a unit into the field.

The disclosure relates to a thermal and/or acoustic insulation system as waterproofing for a flat or flat inclined outside surface of a building, especially for a flat roof or a flat inclined roof, consisting of at least one insulation element made of mineral wool, preferably made of stone wool, and having a major surface, and a lining element consisting of at least a first layer made of lining material and a second layer made of a glue activatable by heat and oriented to the major surface of the insulation element, whereby the major surface of the insulation element is free of protrusions, especially flights, and cavities thereby being planar and whereby the area connection between the insulation element and the lining element is at least 70%, preferably at least 80% of the major surface area of the insulation element.
