A drip edge having a flange configured to rest against a roof surface following installation on a perimeter of the roof surface and a flap hingedly extending from a terminal edge of the flange configured to be positioned a predefined distance towards the center of the roof surface, as measured from an edge of the roof surface on which the flange is configured to be mounted, following installation of the flange on the roof surface, wherein the flap and flange, in combination, form a cavity configured to retain a shingle therein, thereby improving the strength with which the starter shingle is secured to the roof surface against wind uplift while improving its resilience to moisture intrusion and easing installation while also rendering shingle alignment more consistent.

A covering having insulated panels is meant to prevent or slow the spread of fire. Each panel has a top cover; a fire-prevention layer having a fire-retardant material, a fire-resistant material, or a combination of both; and an insulation layer. The fire-prevention layer is located, at least partially, between the top cover and the insulation layer. When there are two or more insulated panels, they interlock at a joint and form a plane.

Flashing for use at the edge of roofs or decks that are provided with surface materials are presented. In exemplary embodiments, flashing may be provided at the edge of a roof to retain or provide an edge treatment for an aesthetic and functional surface material, such as, for example, a cast paver, while at the same time allowing for water drainage. In one embodiment, a piece of flashing material contains a leg that is fastened along the edge of the top of a flat roof. This embodiment continues into two legs that form a V-shaped trough which comes off the roofing membrane and has penetrations at the bottom to release water. The outer leg of the “V” most commonly extends to a level higher than the roofing membrane in order to make contact with and edge an installed surface material. Various other shapes and end treatments, including various embodiments providing both an edge flashing as well as an integrated rectangular shaped gutter-like trough are also presented.

Polyolefin compositions useful for construction articles for outdoor use, for instance house siding, cladding, soffit or roofing. The compositions comprise a polyolefin substrate which has incorporated therein one or more additives selected from the group consisting of a) one or more ultraviolet light absorbers, b) one or more hindered amine light stabilizers and c) one or more antioxidants. Advantageously, the polyolefin substrate also has incorporated therein d) one or more colorants, e) one or more fillers, f) one or more flame retardants and optionally g) one or more antimicrobial compounds. The compositions exhibit certain performance levels according to standard tests, for example impact strength of >35 in-lb per ASTM D4226, coefficient of linear thermal expansion of

A covering employing a fascia gutter is disclosed. The fascia gutter includes a front member, bottom member, a rear member, a ledge, a guiding groove, a protrusion and a receiving space. The bottom member connects the front member to the rear member. The receiving space is defined by the front member, the bottom member, and the rear member. The ledge is connected to the rear member. An opening is defined by the ledge and the protrusion.

Photovoltaic mounting systems that form chemical flashings are provided herein. Such mounting systems can include a mounting plate adapted to interface with an off-the-shelf mounting puck so as to allow mounting of the puck on the roof surface without use of traditional roof flashing and/or modification of shingles of the roof surface. Such mounting plates can include a top surface adapted to interface with the puck and a bottom surface that defines a cavity between the mounting plate and the puck in which to form the chemical flashing by injecting a flowable sealant into the cavity via an inlet of the mounting plate that remains accessible from outside the puck during mounting. Such mounting plates can further include features for orienting the plate, directing runoff away from any sealed roof penetrations and filling of the cavity with flowable sealant.

The present invention relates more particularly to improved flashings for use in integrating specialized roof-mounted structures, such as photovoltaic devices for the generation of electrical energy, with conventional roofing materials on a roof. In one aspect, the invention provides a flashing element having a cross-sectional shape comprising a laterally-extending flange, the flange having an edge, a first end and a second end, the side flashing element comprising a return hem disposed at the edge and comprising a folded-over strip of material disposed over the top surface of the flange at the edge, the return hem having a first end disposed toward the first end of the edge, and a second end disposed toward the second end of the edge, wherein the total thickness of the return hem at its second end is no greater than the interior thickness of the return hem at its first end.
