Abstract
A roofing system having a multiplicity of courses of roofing shingles and interply material comprising at least one course of interply material overlapping at least about ten percent of a first course of shingles and a second course of shingles overlapping at least a portion of the interply material and the first course of shingles. More than about 40% of the first course of shingles is exposed after installation. The roofing system has a class A fire resistant rating. Roofing shingles having particular utility in the roofing system of the present invention are also disclosed. In preferred embodiments the shingles have an exposure width of at least about 60% of the shingle, more preferably at least about 64% of the width of the shingle.
Claims (9)
1. A roofing system comprising:
(a) a roof deck of a building;
(b) a first layer of underlayment material attached to said roof deck, wherein said material is comprised of a substrate having an ionic charge coated with a coating having essentially the same ionic charge wherein said coating consists essentially of a filler material and a binder material and wherein said binder material bonds the filler material together and to the substrate and wherein said coating does not bleed through said substrate;
(c) a second layer of said underlayment material attached to said first layer;
and (d) a multiplicity of courses of roofing shingles attached to said second layer of underlayment material.
(a) a roof deck of a building;
(b) a first layer of underlayment material attached to said roof deck, wherein said material is comprised of a substrate having an ionic charge coated with a coating having essentially the same ionic charge wherein said coating consists essentially of a filler material and a binder material and wherein said binder material bonds the filler material together and to the substrate and wherein said coating does not bleed through said substrate;
(c) a second layer of said underlayment material attached to said first layer;
and (d) a multiplicity of courses of roofing shingles attached to said second layer of underlayment material.
2. The roofing system according to claim 1, wherein said underlayment material is from 10% to 25% by weight of glass of fibers and said coating is from 84% to 96% filler selected from the group consisting of fly ash, charged calcium carbonate, ceramic microspheres and mixtures thereof, and from 16% to 4% acrylic latex binder material.
3. The roofing system according to claim 1, wherein said underlayment material is comprised of a substrate having an ionic charge, (a) coated on one side with a coating having essentially the same ionic charge wherein said coating consists essentially of a filler material and a binder material and wherein said binder material bonds the filler material together and to the substrate and wherein said coating does not bleed through said substrate; and (b) covered on the other side with a water vapor impermeable material selected from the group consisting essentially of metal foils and preformed plastic films;
wherein said water vapor impermeable material is attached to said coated substrate with an adhesive.
wherein said water vapor impermeable material is attached to said coated substrate with an adhesive.
4. The roofing system according to claim 1, wherein said underlayment material is comprised of a substrate having an ionic charge coated on both sides with a coating having essentially the same ionic charge wherein said coating consists essentially of a filler material and a binder material and wherein said binder material bonds the filler material together and to the substrate and wherein said coating does not bleed through said substrate;
wherein one side of said coated substrate is covered with a water vapor impermeable material selected from the group consisting essentially of metal foils and preformed plastic films; and wherein said water vapor impermeable material is attached to said coated substrate with an adhesive.
wherein one side of said coated substrate is covered with a water vapor impermeable material selected from the group consisting essentially of metal foils and preformed plastic films; and wherein said water vapor impermeable material is attached to said coated substrate with an adhesive.
5. The roofing system according to claim 4, wherein one side of said coated substrate is covered with a metal foil water vapor barrier material and the other side of said coated substrate is covered with a preformed plastic film water vapor impermeable material; and wherein both water vapor impermeable materials are attached to said coated substrate with an adhesive.
6. The roofing system according to claim 4, wherein both sides of the coated substrate are coated with a metal foil water vapor impermeable material and wherein said water vapor impermeable material is attached to said coated substrate with an adhesive.
7. The roofing system according to claim 4, wherein both sides of the coated substrate are coated with a preformed plastic film water vapor impermeable material and wherein said water vapor impermeable material is attached to said coated substrate with an adhesive.
8. The roofing system according to any one of claims 3 to 7, wherein said adhesive is selected from the group consisting essentially of low density polyethylene, high density polyethylene, polyethylene-vinyl acetate, polypropylene, polyvinylidene chloride, nylon, polyester, asphaltic adhesive and mixtures thereof.
9. The roofing system according to claim 8, wherein said coating is from 84%
to 96%
filler selected from the group consisting of fly ash, charged calcium carbonate, ceramic microspheres and mixtures thereof and from 16% to 4% acrylic latex binder material.
to 96%
filler selected from the group consisting of fly ash, charged calcium carbonate, ceramic microspheres and mixtures thereof and from 16% to 4% acrylic latex binder material.
