A fastener plate for use in coupling an underlayment to a roof surface is disclosed. In use, the fastener plate is arranged and configured to enable subsequently applied liquid coatings to flow through a top surface of the fastener plate and into one or more cavities so that the liquid coating seals any openings created by introduction of the fastener. In one embodiment, the fastener plate may include a top surface, a bottom surface, a fastener opening for receiving a fastener, a plurality of openings formed in the top surface, and one or more cavities positioned between the top surface and the bottom surface, the one or more cavities being in fluid communication with the plurality of openings so that the liquid coating can flow through the plurality of openings formed in the top surface and into the one or more cavities to seal any voids created by the fastener.

Panels with substantially integrated watershedding features may be installed on the roof a house or other structure in lieu of traditional roofing materials. The panels include a body formed from a mixture of filler materials and polymeric binder materials, which can include recycled materials, with watershedding features generally formed with and/or integrated with the panels. The panels also can be installed in overlapping courses along a roof with the watershedding features incorporated along one or more peripheral edges. The watershedding features of adjacent panels further can cooperated to collect and divert water away from the upper surfaces and/or away headlap and/or sidelap joints defined between the panels.

Roofing shingles are disclosed that are capable of self-adhering to a roof deck or underlayment and/or other roofing shingles and that require few or no mechanical fasteners to remain attached to the roof. By appropriate positioning of sealant lines on the shingle, direct adhesion between the shingle and the roof deck or underlayment and/or other roofing shingles can be achieved. If the shingle is laminated, the layers may be mechanically attached with indentations in the common bond area. The nail zone of the shingle may be visually indicated with fines and/or one or more paint lines. A roofing system comprising a plurality of courses of the shingles is also disclosed.
