Roofing panels with water shedding features may be installed on the roof of a house or other structure in lieu of or as an underlayment for traditional roofing materials. The water shedding features can be built into a base of the roofing panels, as part of a frame for the roofing panels, or formed as part of a waterproofing layer applied to the base of the roofing panels, or which can be configured as a roofing panel. The roofing panels also can be installed in overlapping courses along a roof with water shedding features applied thereto or incorporated along one or more peripheral edges. The water shedding features of adjacent roofing panels will collect and divert water away from the upper surfaces and/or away from headlap and/or sidelap joints defined between the roofing panels.

Implementations described and claimed herein provide for modular snow and ice retention and mounting systems. In various embodiments, a bracket may comprise a mounting strap, a hybrid pad, a bracket assembly and a rod. The hybrid pad may comprise a face portion and a support portion. The face portion and the support portion may be operatively coupled together. The hybrid pad may be operatively coupled to the mounting strap. The face portion may comprise a stiffening rib. The stiffening rib may be defined in a front surface of the face portion. The stiffening rib may define a first load plane. The face portion may also define a first rod notch. The first rod notch may be defined on a first side of the face portion. The face portion may also define a second rod notch. The rod may be mountable to the hybrid pad.

A telescoping rail assembly for a roof hatch includes a bracket configured to couple to the roof hatch, where the roof hatch is configured to provide access to a roof of a building, a post coupled to the bracket and configured to extend from the roof hatch and outward from the roof, and a telescoping rail having a first portion and a second portion, where the first portion and the second portion are slidably adjustable with respect to one another, and where the telescoping rail is disposed along a portion of a perimeter of the roof hatch to enable the telescoping rail assembly to enclose an area that includes the roof hatch.

A roof curb is used in association with a roof flashing installed on a roof with an incline and corrugated ribs, the roof flashing having a base member that may be mounted over a substantially vertical chimney in the roof and a hollow member having a first end and a second end, the first end being larger than the second end and the first end being attached to the base member of the roof flashing. The roof curb includes a first skid and a second skid that may be mounted upon the roof substantially in a direction of the incline and substantially parallel to each other. The first skid and the second skid each have a length that terminates in a top end and a bottom end, each of the first skid and the second skid being tapered such that the bottom end of each of the first and the second skids has a height greater than the top end, the first and the second skids being selectively attached to the roof to bridge the corrugated ribs and the taper being of a gradation to permit attachment of the roof flashing to the roof curb and passage of the substantially vertical chimney therethrough, the roof curb being discrete from the roof flashing.

Headwall flashing and sloped wall flashing, each having a ledge, where the ledges are designed to meet at an outside corner of a roof protrusion comprising a headwall and a cheek wall, the headwall flashing being configured to abut a face of the roof protrusion and having a downwardly-angled ledge that ties into the ledge of the sloped roof flashing, which is angled such that it forms a consistent ledge for installation of siding up a cheek wall, despite the siding creating a shimming effect that would typically result in a stepped appearance and misalignment thereof.

A sealed attic insulating and roof ventilating system includes a plenum formed in part by a barrier material attached to adjacent pairs of rafters and having a radiant or reflective upper surface and a corrugated lower surface to which an insulation material may be secured. This arrangement creates an uninterrupted air chamber or ventilation plenum between the barrier material, the adjacent rafters, and the roof decking through which exterior air can circulate unimpeded from the lower vents to the upper vents of the roof. The circulation through the ventilation plenum prevents moisture from accumulating or condensing under the roof decking and warping the roof decking, which ultimately leads to deterioration of the roof decking and failure of the roof covering, and eliminates ice damming on the top surface of the roof covering.
