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;
- a fastener cap having an opening defined therethrough, wherein the opening is configured to receive the fastener therethrough;
- wherein the fastener cap comprises a central portion and an outwardly flaring peripheral portion surrounding the central portion;
- wherein the opening of the fastener cap is formed through the central portion;
- and
- a sealant material positioned within a space defined below the fastener cap;
- wherein the sealant material is adapted to disperse along the fastener plate space below the fastener cap so as to substantially cover and seal the space defined below the fastener cap when the fastener is received through the opening defined in the fastener cap;
- wherein the fastener cap is configured to move into contact with the sealant material as the fastener is received through the opening so as to urge the sealant material under pressure from the fastener cap to flow about the space defined below the fastener cap and toward the peripheral portion.
5 more elements
A roofing system comprising:
- a plurality of roof panels;
- a plurality of self-sealing fasteners positioned on each roof panel, each self-sealing fastener comprising,
- a fastener plate including a fastener and a fastener cap having an opening configured to receive the fastener therethrough;
- 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;
- wherein the fastener cap further comprises a central portion and an outwardly flaring peripheral portion surrounding the central portion;
- wherein the opening of the fastener cap is formed through the central portion;
- and
- wherein the fastener cap is configured to move into contact with the sealant material as the fastener is received through the opening so as to urge the sealant material under pressure from the fastener cap to flow throughout the space defined below the fastener cap, toward the peripheral portion and at least partially into a penetration hole at least partially formed in the roof panel when the fastener penetrates the roof panel.
6 more elements
A fastening system, comprising:
- a fastener;
- a fastener cap having an opening, wherein the opening is configured to receive the fastener therethrough;
- a sealant material positioned within a space defined below the fastener cap;
- and
- an agitator positioned in the space defined below the fastener cap, the agitator comprising a paddle projecting radially from a central hub;
- 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 to disperse the sealant material within the space defined below the fastener plate cap when the fastener is received through the opening defined in the fastener cap.
