A retractable roof system includes a support structure, having a first vertical leg, a second vertical leg, a third vertical leg, and a fourth vertical leg extending upward from a ground surface; a first guide track extending from the first vertical leg to the second vertical leg; a second guide track extending from the third leg to the fourth leg; a first support beam connecting the first vertical leg and the third vertical leg; and a second support beam connecting the second vertical leg and the fourth vertical leg; a roof retractably secured on the support structure, the roof having: a frame having a first edge aligned with the first track and a second edge aligned with the second track; rollers connected to the first edge and the second edge to slidingly engage with the first track and the second track; and a flexible roofing material secured on the roof frame; a pulley attached to the first end of the frame; force exerted on the pulley pulls a set of the rollers towards a center of the roof, causing a first end of the frame to retract.

A roof cover board made from a mixture of 30-60% stucco; 20-50% perlite; 10-30% cellulose fiber; 3-20% starch; and siloxane. Also disclosed is a stucco-free roof cover board made from a mixture of 30-60% perlite, 30-60% cellulose fiber, 5-25% starch; and siloxane. Also disclosed are methods for making same.

A covering of a damaged or uncompleted building; the covering including a film of heat shrinkable material stretched over damaged or uncompleted portions of the building; the film formed as a sheet comprising an assembly of lengths of the heat shrinkable material applied to surfaces of the building.

A method of providing covers over at least a portion of a roof of a storm damaged built structure that includes the steps of: applying a sheet of heat shrinkable film over the portion of the roof, the sheet having a leading edge and a trailing edge and being a film of low density polyethylene including shrinking resins; wrapping portions of the leading edge around a first batten and attaching the first batten to the underside of a first eave or to the facia of the built structure; wrapping portions of the trailing edge around a second batten and attaching the second batten to the underside of a second eave or to the facia of the built structure at a location different than the first batten; and heating the sheet of heat shrinkable film to bring the film into conformity with the portion of the roof, wherein the heating step shrinks the sheet of film tight against the built structure to cover over the portion of the roof.

In one aspect there is provided an insulated modular roof system for a roof structure. The system comprises a plurality of modular panels suitable for installation onto the roof structure and a water-proof membrane. Each of the plurality of modular panels comprises a first planar member, an insulating layer covering substantially all of the first planar member and a second planar member suitable to cover substantially all of the insulating layer. Preferably, the system further comprises a joint closure member and a joint fill material suitable to fill any empty space between any abutting modular panels. The water-proof membrane may be provided in sections on each of the plurality of modular panels.

Silicone membranes and methods of manufacturing membranes are provided.

A method of installing a wind-resistant roof underlayment is disclosed that includes providing a wind-resistant roof underlayment having a lower surface including an adhesive medium. The wind-resistant roof underlayment includes an upper surface having a first non-release liner portion with a width of at least three inches. A second release liner portion is provided having a width of at least eight inches. The second release liner portion is disposed in an overlapping relationship with an upper surface adhesive medium coupled to the upper surface. The method includes coupling the lower surface to a roof deck, with a portion of the second release liner portion at a position substantially adjacent to an eave of the roof deck, removing the second release liner portion, thereby exposing an adhesive strip of the upper surface adhesive medium, and coupling a plurality of shingles to the strip of the upper surface adhesive medium.
