Retractable roof and/or wall panels are disclosed herein. Such panels may be used as roof or wall portions for tents or other temporary structures allowing for variable outdoor exposure and easy transitions from indoor to outdoor spaces.

A method includes obtaining a roofing membrane. A first layer of the roofing membrane is applied along a length of a roofing substrate covering a first portion of the roofing substrate. At least a first edge of the first layer is fastened to the roofing substrate. A second layer of the roofing membrane is applied over the first layer along the length of the roofing substrate such that a first edge of the second layer overlies the second edge of the first layer. The first edge of the second layer and the second edge of the first layer are fastened to the roofing substrate using a second fastener in a fastening zone along the length the roofing substrate. The second layer is reoriented such that the second layer overlies the fastening zone and covers a second portion of the roofing substrate adjacent the first portion of the roofing substrate.

A roof system comprising a roof substrate, a first membrane including first and second opposed planar surfaces, and a second membrane including opposed first and second planar surfaces, where said second membrane is adhered to said roof substrate through an adhesive disposed on said roof-substrate contacting portion of the first membrane, and where said second membrane is adhered to said first membrane through said adhesive disposed on a lap portion of said second membrane.

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.

A method is provided for forming an adhered membrane roof system that meets Factory Mutual (FM) 4470/4474 standards for wind uplift. The method comprises applying a bond adhesive to a substrate on a roof to form an adhesive layer and applying a membrane directly to the adhesive layer. The bond adhesive includes a moisture-curable polymer.

A roof product has a thermal heat storage layer, a vent layer with channels for transferring excess heat through a length of the roof product, and a flame retardant to suppress fire through the vent layer. These three materials form a unitary structure. The roof product may have a radiant layer, the thermal heat storage layer and the vent layer to form the unitary structure. The roof products are assembled in an abutting configuration on the roof of a building. The vent layer vents excess heat from an eave of the roof up to a ridge of the roof and out to atmosphere. The roof products manage thermal energy in the roof by storing thermal heat with the unitary roof product during a heating cycle; venting excess heat through the unitary product; and releasing the stored thermal heat from the unitary product into or out of the building during a cooling cycle.

A roofing membrane includes a membrane layer. An adhesive layer is adhered to a first side of the membrane layer and a layer of granules is adhered to the first adhesive layer.

Some embodiments of the present technology may encompass roofing membranes. The roofing membranes may include a waterproof membrane having a top major surface. The roofing membranes may include a first liner having a top surface and a bottom surface. The bottom surface of the first liner may be removably coupled with the top major surface of the waterproof membrane. The first liner may have a first color. The roofing membranes may include a second liner having a top surface and a bottom surface. A bottom surface of the second liner may be coupled with the top surface of the first liner. The second liner may have a second color that is different than the first color.

A sheet material for roofing to be installed on a roof under an overlayment comprising a closed-weave woven having a top side and a back side; a thermoplastic layer affixed on the top side; and a water-based adhesive coating affixed on the back side. The sheet material is manufactured as a roll in which the thermoplastic layer isolates the water-based adhesive coating from an immediate environment when the sheet material is in a roll form.
