Roofing shingle system and shingles for use therein
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.
1 . A roofing system comprising:
a roofing substrate;
a first course of roofing shingles adhered to the roofing substrate, the first course comprising at least one first course roofing shingle having:
(a) a front surface, a back surface, a top edge, a lower edge, a length, and a width;
(b) a first sealant line disposed on the front surface of the at least one first course roofing shingle that extends substantially across the length of the front surface of the at least one first course roofing shingle; and
(c) a first sealant line disposed on the back surface of the at least one first course roofing shingle that extends substantially across the length of the back surface of the at least one first course roofing shingle,
wherein the first sealant line disposed on the back surface of the at least one first course roofing shingle is the only sealant line on the back surface of the at least one first course roofing shingle,
wherein the first sealant line disposed on the back surface of the at least one first course roofing shingle is disposed near the top edge of the at least one first course roofing shingle, and
wherein the first sealant line disposed on the back surface of the at least one first course roofing shingle is adhered only to the roofing substrate; and
a second course of roofing shingles vertically adjacent to the first course, the second course comprising at least one second course roofing shingle.
2 . The roofing system of claim 1 , wherein the first sealant line disposed on the front surface of the at least one first course roofing shingle is adhered to the at least one second course roofing shingle.
3 . The roofing system of claim 1 , wherein the first sealant line disposed on the front surface of the at least one first course roofing shingle is the only sealant line on the front surface of the at least one first course roofing shingle.
4 . The roofing system of claim 1 , wherein the at least one first course roofing shingle is a single layer shingle.
5 . The roofing system of claim 4 , wherein the at least one first course roofing shingle has no cuts, tabs, or openings.
6 . The roofing system of claim 1 , wherein at least one of the first sealant line disposed on the front surface or the first sealant line disposed on the back surface of the at least one first course roofing shingle is formed as one of (i) a continuous strip of sealant or (ii) a dashed or dotted strip of sealant.
7 . The roofing system of claim 1 , wherein at least one of the first sealant line disposed on the front surface or the first sealant line disposed on the back surface of the at least one first course roofing shingle is covered with a release tape.
8 . The roofing system of claim 1 , wherein the roofing substrate comprises a roof deck or an underlayment that is positioned on a roof deck.
9 . The roofing system of claim 1 , wherein the roofing system passes the ASTM D3161 test at 110 mph.
10 . A method comprising:
obtaining a plurality of first course roofing shingles;
adhering the plurality of first course roofing shingles as a first vertical course on a roofing substrate;
obtaining a plurality of second course roofing shingles; and
adhering the plurality of second course roofing shingles to the first course roofing shingles in a vertically adjacent orientation,
wherein each roofing shingle of the plurality of first course roofing shingles includes:
(a) a front surface, a back surface, a top edge, a lower edge, a length, and a width;
(b) a first sealant line disposed on the front surface of each roofing shingle of the plurality of first course roofing shingles that extends substantially across the length of the front surface of each roofing shingle of the plurality of first course roofing shingles; and
(c) a first sealant line disposed on the back surface of each roofing shingle of the plurality of first course roofing shingles that extends substantially across the length of the back surface of each roofing shingle of the plurality of first course roofing shingles, and
wherein the first sealant line disposed on the back surface of each roofing shingle of the plurality of first course roofing shingles is the only sealant line on the back surface of each roofing shingle of the plurality of first course roofing shingles,
wherein the first sealant line disposed on the back surface of each roofing shingle of the plurality of first course roofing shingles is disposed near the top edge of each roofing shingle of the plurality of first course roofing shingles, and
wherein the first sealant line disposed on the back surface of each roofing shingle of the plurality of first course roofing shingles is configured to adhere only to the roofing substrate.
11 . The method of claim 10 , further comprising adhering the first sealant line disposed on the back surface of each roofing shingle of the plurality of first course roofing shingles only to the roofing substrate.
12 . The method of claim 10 , further comprising adhering the first sealant line disposed on the front surface of each roofing shingle of the plurality of first course roofing shingles only to a roofing shingle of the plurality of second course roofing shingles.
13 . The method of claim 10 , wherein the first sealant line disposed on the front surface of each roofing shingle of the plurality of first course roofing shingles is the only sealant line on the front surface of each roofing shingle of the plurality of first course roofing shingles.
14 . The method of claim 10 , wherein each roofing shingle of the plurality of first course roofing shingles is a single layer shingle.
