Abstract
A self-sealing fastener for installation of roofing materials for creating a substantially watertight seal around fastener penetrations where roofing materials or panels are affixed to an underlying roof deck by the fasteners. Also disclosed is a method for installing the self-sealing fastener for attachment of roofing materials to an underlying roof deck with the penetrations areas or holes created by the fasteners being substantially sealed against water penetration.
Claims19
A fastening system, comprising:
- a fastener plate comprising a fastener cap, a fastener, and an opening, defined along the fastener cap, and wherein the opening is configured to receive the fastener therethrough;
- and
- a sealant material positioned within a space defined below the fastener cap;
- wherein the sealant material is adapted to engage the fastener and disperse along the fastener plate when the fastener is received through the opening defined in the fastener caps;
- wherein the fastener cap further comprises a central portion, an outwardly flaring portion, and at least one passage defined between the central portion and the outwardly flaring portion of the fastener cap, and adapted to facilitate passage of air through the fastener cap and into contact with the sealant material to promote curing of the sealant material.

A roofing system comprising:
- a plurality of roof panels, each roof panel configured to overlie an upper surface of a roof deck;
- a fastener assembly positioned on each roof panel, each fastener assembly comprising,
- a fastener plate including a fastener cap having an opening, and a fastener, wherein the opening of the fastener cap is configured to receive the fastener therethrough to penetrate into a roof panel on which the fastener assembly is positioned to at least partially form a penetration hole therein;
- and
- a sealant material positioned within a space defined between the fastener plate and the roof panel, wherein the sealant material is dispersed along the roof panel and flows at least partially into the penetration hole at least partially formed in the roof panel when the fastener is moved through the opening and penetrates the roof panel;
- wherein the sealant material comprises an amount of sealant material selected such that upon dispersion of the sealant material along the roof panel and at least partially into the penetration hole, the sealant material has a thickness sufficient to form a substantially watertight seal and occupies less than an entire volume of the space defined between the fastener plate and the roof panel.

- a fastener plate including a fastener cap having an opening, and a fastener, wherein the opening of the fastener cap is configured to receive the fastener therethrough to penetrate into a roof panel on which the fastener assembly is positioned to at least partially form a penetration hole therein;
- a sealant material positioned within a space defined between the fastener plate and the roof panel, wherein the sealant material is dispersed along the roof panel and flows at least partially into the penetration hole at least partially formed in the roof panel when the fastener is moved through the opening and penetrates the roof panel;
- and
- an agitator positioned in the space, the agitator comprising a paddle projecting radially from a central hub, and wherein the fastener is adapted to engage the central hub of the agitator and cause the agitator to engage and stir the sealant material within the space.
