A thermally modulating roof system wherein a minority of climate space between an existing and new roof is occupied by a phase change material assembly. The system maintains an industry standard of no more than a distance of about 4 inches between the roofs while still incorporating a substantial capacity to modulate an otherwise rising temperature of a facility during the day. Unique methods of installing the system, utilizing it and circulating air through the system to enhance performance are detailed.

The present concept is a method of roofing a bare roof deck. Asphalt shingles and metal flashings are applied to a wood deck of a roof before flashings and asphalt capping are applied. Metal panels are applied overtop of existing asphalt roof, thereby creating a metal overlay configured such that substantially all of the asphalt shingles are covered with a metal panel for preventing further degradation of asphalt components by shielding from sunlight, UV rays, excessive moisture, snow, wind, ice and fire. No further flashings are installed thereby the metal panel overlay creates a semi-watertight seal wherein the metal panel overlay together with asphalt roof is adapted to create a watertight seal. The present concept is also a method for roofing an existing asphalt shingled roof where metal panels are applied overtop the existing asphalt shingled roof. This creates a metal overlay that covers substantially all of the asphalt shingles for preventing further degradation of asphalt components, and provides a method of preserving an asphalt shingled roof.

An expandable flashing device comprises first and second pieces of flashing material that overlap one another with hems or folded edges located on opposite lateral sides of the pieces that hold the pieces together, yet allow the pieces to slide or shift with respect to one another to selectively change the length of the device. In a first stowed position, the pieces overlap one another and in an expanded second position, the pieces may be pulled apart to increase an overall length of the pieces. The maximum length of material that overlaps between the pieces is defined as the overlap range. The overlap range defines the range to which the device can be shortened or lengthened to fit a particular installation. A flashing system and a method of installing flashing are also disclosed.

The roof valley batten is configured for use with a roof. The roof valley batten attaches a plurality of shingles to a structure formed by a roof valley and a metal valley. The roof valley batten attaches to the metal valley in a manner that does not require the use of a fastening device that perforates a structure selected from the group consisting of the roof valley and the metal valley. The roof valley batten provides a mounting structure for the plurality of shingles that allows the use of a fastening device that does require the perforation of the roof valley batten. The roof valley batten comprises a mounting surface, a plurality of pedestals and a plurality of channels. The plurality of pedestals attach to the mounting surface. The plurality of channels are drainage channels formed within the plurality of pedestals.

A device and method for covering a roof. The interlocking roof shingle includes a shingle having a top surface and a bottom surface. A first edge of the shingle is curved over the top surface and a second edge of the shingle is curved under the bottom edge of the shingle. The first edge of the shingle is configured to engage with the second edge of an adjacent shingle. The device further includes a tab configured to receive a nail and engage with the first edge of the shingle. Some embodiments of the shingle are configured to fit along the ridges and valleys of a roof. In these embodiments, the shingle has a center fold and a gap in the upper and lower folded edges.

A ridge structure at a roof edge, having a base panel lying on a roof surface and a hollow ridge structure over the base panel. The hollow ridge structure is constructed in a flat spring form along the eaves, and therefore one slope of the ridge faces the roof and the other slope the opposite direction. The slope facing the roof can be lifted to receive and secure roofing materials between the slope and the base panel. When water flows down the roof surface, most water flows over the ridge structure and the rest flows into the hollow space inside the ridge structure and drains through drain holes on the base panel.
