Abstract
This invention relates to an underlayment for use under a plurality of courses of roofing shingles. The underlayment includes a water impermeable membrane layer containing at least one flap extending horizontally across the membrane layer. The flap is movable between a flat position and a raised position. In the raised position, an upper edge of a roofing shingle can be positioned under the flap. The upper edge of the roofing shingle can then be subsequently overlapped by the flap when the flap is moved into the flat position. The flap can then subsequently be overlapped by another course of roofing shingles.
Claims27
An underlayment for use under a plurality of courses of roofing shingles, the underlayment comprising:
- a water impermeable membrane layer, wherein the membrane layer contains at least one flap extending horizontally across the membrane layer, wherein the flap is movable between a flat position and a raised position, wherein in the raised position an upper edge of a roofing shingle can be positioned under the flap, wherein the upper edge of the roofing shingle can be subsequently overlapped by the flap when the flap is moved into the flat position, and wherein the flap can be subsequently overlapped by another course of roofing shingles.
A roofing system suitable for being applied to a roof deck, the system comprising:
- a plurality of courses of roofing shingles;
- and
- an underlayment layer disposed over the roofing deck, the underlayment layer comprising a water impermeable membrane layer, wherein the membrane layer contains at least one flap that extends horizontally across the membrane, wherein the flap is movable between a flat position and a raised position, wherein in the raised position, an upper edge of a roofing shingle can be positioned under the flap, wherein the upper edge of the roofing shingle is subsequently overlapped by the flap when the flap is moved into the flat position, and wherein the flap is then subsequently overlapped by another course of roofing shingles.
An underlayment for use under a plurality of courses of roofing shingles, the underlayment comprising:
- a base layer;
- a reinforcing material applied to the base layer;
- and
- a water impermeable membrane layer applied over the base layer and reinforcing material, wherein the membrane layer contains at least one flap extending horizontally across the membrane, wherein the flap is movable between a flat position and a raised position, wherein in the raised position an upper edge of a roofing shingle can be positioned under the flap, wherein the upper edge of the roofing shingle can be subsequently overlapped by the flap when the flap is moved into the flat position, and wherein the flap can then be subsequently overlapped by another course of roofing shingles.
