Cool Roofs
The Cool-America Plan supports the ENERGY STAR® Program previously implemented under the 2008 Stimulus. Tax Credits shall now apply to ALL TYPES of roofs substrates providing that solar reflecttive surfaces (albedo) meet the is .4 SRI standard or higher. Categories of roofs now eligible are defined by Energy Star as follows:
Asphalt Shingles:
omposed of a base material, either organic felt or glass fiber mat; asphalt; and surfacing material, generally in the form of mineral granules.
Metal Products: Metal roof product designed to resemble a traditional steep-slope residential
product such as shingle, tile, shake, or slate.
Metal Panels: Roofing systems using metal panels are divided into two categories: architectural and structural. Architectural metal roofs are applied over a substrate while structural metal roofs span between structural supports without the need for a substrate to carry the applied
Modified Bitumen: Roll roofing products consisting of asphalt, reinforcing layers, and in some cases, surfacing. During manufacture, a polymer (APP, or atactic polypropylene, and SBS, or styrene butadiene styrene, are the most common) is added to the bitumen while heating, which "modifies," or changes, its properties.
Roof Coating: A material typically applied in the liquid state to the roof surface at the time of construction or at a later time as a retrofit measure. Roof coatings may be bituminous, polymeric, polymer modified, epoxy based, or other formulations. Bituminous roof coatings are formulated using bitumen. Polymeric roof coatings are formulated using a variety of synthetic resins such as acrylic, neoprene, styrene butadiene, urethane, polyvinyl acetate, and others. Polymer modified roof coatings are manufactured by combining a portion of the polymeric technology with bitumen technology.
Roof Tile: May be composed of clay, concrete, fiber-cement, or synthetic materials. A variety of tile profiles, styles, finishes, and colors are available.
Membrane: A term applied to a sheet membrane which is a membrane fabricated in a controlled factory environment. It is waterproof and weather resistant. It may be a laminate of one or more materials and may or may not contain reinforcing fabrics.
Spray Poly-Foam: A fully adhered system that consists of a rigid closed-cell sprayed-in-place polyurethane foam insulation and a protective roof coating. Typical coatings include acrylic, silicone, or urethane elastomers.
Variegated: A material with a varied surface color, requiring a larger sample for measurement of Solar Reflectance.
Factory-Applied: A material or component made and applied by a licensed Original Manufacturer (OM)
