ENERGY STAR® Program Requirements
for Roof Products
Partner Commitments
Revised FINAL DRAFT
Commitment
The following are the terms of the ENERGY STAR Partnership Agreement as it pertains to the
manufacturing of ENERGY STAR qualified roof products. The ENERGY STAR Partner must adhere to
the following program requirements:
•	comply with current ENERGY STAR Eligibility Criteria, defining the performance criteria that must be
met for use of the ENERGY STAR certification mark on roof products and specifying the testing
criteria for roof products. EPA may, at its discretion, conduct tests on products that are referred to as
ENERGY STAR qualified. These products may be obtained on the open market, or voluntarily
supplied by Partner at EPA's request;
•	comply with current ENERGY STAR Identity Guidelines, describing how the ENERGY STAR marks
and name may be used. Partner is responsible for adhering to these guidelines and for ensuring that
its authorized representatives, such as advertising agencies, dealers, and distributors, are also in
compliance;
•	qualify at least one ENERGY STAR roof product within one year of activating the roof products
portion of the agreement. When Partner qualifies the product, it must meet the specification (e.g.,
Tier 1 or 2) in effect at that time;
•	provide clear and consistent labeling of ENERGY STAR qualified roof products. The ENERGY STAR
mark must be clearly displayed in product literature (i.e., user manuals, spec sheets, etc.) and on the
manufacturer's Internet site where information about ENERGY STAR qualified products is displayed;
•	through product literature, provide the following information to end users: 1) a description of the
variables that influence the amount of energy savings that can be realized when an ENERGY STAR
qualified roof product is installed on a home or building, 2) an acknowledgement that the solar
reflectance of any roof products overtime may increase or decrease, depending on the product
make-up, due to aging and dirt and microbial accumulation, and 3) a description of the proper
maintenance procedures required to maximize solar reflectance over the longest period of time
possible (e.g., rinsing or power washing each spring or recoating every five years). Partners may
continue to use the following statement to meet this requirement: "When installed properly, this
product will help reduce energy costs. Actual savings will vary based on geographic location and
individual building characteristics. Consult your product manufacturer, roofing contractor, or call 1-
888-STAR-YES (1-888-782-7937) for more information." This statement must be placed in close
proximity to the ENERGY STAR mark wherever it is included in product literature and on the
manufacturer's Internet site.
•	provide to EPA, on an annual basis, an updated list of ENERGY STAR qualifying roof product
models. Once the Partner submits its first list of ENERGY STAR qualified roof products, the Partner
will be listed as an ENERGY STAR Partner. Partner must provide annual updates in order to remain
on the list of participating product manufacturers;
•	for each qualifying roof product, provide to EPA test data to certify that the product has met the
required performance characteristics. This data may be in the form of a testing report, either from the
Partner or a third party. EPA will only add models to its product list after reviewing and approving the
product test results;
ENERGY STAR Version 2.0 Program Requirements for Roof Products: Revised Final Draft	1

-------
•	provide to EPA, on an annual basis, unit shipment data or other market indicators to assist in
determining the market penetration of ENERGY STAR. Specifically, Partner must submit the total
number of ENERGY STAR qualified roof products shipped (in units by model) or an equivalent
measurement as agreed to in advance by EPA and Partner. Partner is also encouraged to provide
ENERGY STAR qualified unit shipment data segmented by meaningful product characteristics (e.g.,
capacity, size, speed, or other as relevant), total unit shipments for each model in its product line,
and percent of total unit shipments that qualify as ENERGY STAR. The data for each calendar year
should be submitted to EPA, preferably in electronic format, no later than the following March and
may be provided directly from the Partner or through a third party. The data will be used by EPA only
for program evaluation purposes and will be closely controlled. If requested under the Freedom of
Information Act (FOIA), EPA will argue that the data is exempt. Any information used will be masked
by EPA so as to protect the confidentiality of the Partner;
•	notify EPA of a change in the designated responsible party or contacts for roof products within 30
days.
Performance for Special Distinction
In order to receive additional recognition and/or support from EPA for its efforts within the
Partnership, the ENERGY STAR Partner may consider the following voluntary measures and should keep
EPA informed on the progress of these efforts:
•	consider energy efficiency improvements in company facilities and pursue the ENERGY STAR mark
for buildings;
•	purchase ENERGY STAR qualified products. Revise the company purchasing or procurement
specifications to include ENERGY STAR. Provide procurement officials' contact information to EPA
for periodic updates and coordination. Circulate general ENERGY STAR qualified product
information to employees for use when purchasing products for their homes;
•	ensure the power management feature is enabled on all ENERGY STAR qualified monitors in use in
company facilities, particularly upon installation and after service is performed;
•	provide general information about the ENERGY STAR program to employees whose jobs are
relevant to the development, marketing, sales, and service of current ENERGY STAR qualified
product models;
•	feature the ENERGY STAR mark(s) on Partner Web site and in other promotional materials. If
information concerning ENERGY STAR is provided on the Partner Web site as specified by the
ENERGY STAR Web Linking Policy (this document can be found in the Partner Resources section
on the ENERGY STAR Web site at www.enerqvstar.gov). EPA may provide links where appropriate
to the Partner Web site;
•	provide a simple plan to EPA outlining specific measures Partner plans to undertake beyond the
program requirements listed above. By doing so, EPA may be able to coordinate, communicate,
and/or promote Partner's activities, provide an EPA representative, or include news about the event
in the ENERGY STAR newsletter, on the ENERGY STAR Web pages, etc. The plan may be as
simple as providing a list of planned activities or planned milestones that Partner would like EPA to
be aware of. For example, activities may include: (1) increase the availability of ENERGY STAR
labeled products by converting the entire product line within two years to meet ENERGY STAR
guidelines; (2) demonstrate the economic and environmental benefits of energy efficiency through
special in-store displays twice a year; (3) provide information to users (via the Web site and user's
manual) about energy-saving features and operating characteristics of ENERGY STAR qualified
products, and (4) build awareness of the ENERGY STAR Partnership and brand identity by
collaborating with EPA on one print advertorial and one live press event;
•	provide quarterly, written updates to EPA as to the efforts undertaken by Partner to increase
availability of ENERGY STAR qualified products, and to promote awareness of ENERGY STAR and
its message.

ENERGY STAR® Program Requirements
for Roof Products
m
Eligibility Criteria
Revised FINAL DRAFT
Below is the REVISED FINAL DRAFT product specification (Version 2.0) for ENERGY STAR qualified
roof products. A product must meet all of the identified criteria if it is to earn the ENERGY STAR.
1) Definitions: Below is a brief description of roof products and other terms relevant to ENERGY STAR.
A.	Roof surface: The uppermost part of the roof system that is in direct contact with solar radiation.
B.	Low-Slope Roofs: Surfaces with a slope of 2:12 or less.1
C.	Steep-Slope Roofs: Surfaces with a slope greater than 2:12.
D.	Low-Slope Roof Products: Products that are typically installed on low-slope surfaces such as
single-ply membranes, built-up-roofs (BUR), modified bitumen, spray polyurethane foam, roof
coatings, metal panels, and standing-seam profiled metal. Some products that are typically
installed on low-slope roofs may also be installed on steep-slope roofs (e.g., single-ply
membranes and roof coatings). For the purposes of this specification, the roof product will
constitute the uppermost surface of the building structure.
E.	Steep-Slope Roof Products: Products that are typically installed on steep-slope surfaces such as
composite shingles, clay, concrete, or fiber-cement tile, slate, metal panels, and metal shingles.
Some products that are typically installed on low-slope roofs may also be installed on steep-slope
roofs (e.g., single-ply membranes and roof coatings). For the purposes of this specification, the
roof product will constitute the upper most surface of the building structure.
Roof Product Technologies
F.	Built-Up-Roof (BUR): Traditional hot asphalt or coal tar built-up roofing membrane assembly
consists of alternating layers of felts, fabrics, or mats saturated with bitumen during manufacture,
assembled in place, and adhered with applied layers of hot bitumen. Surfacing for the hot BUR
can be aggregate embedded in hot asphalt; mineral-surface cap sheets; modified bitumen cap
sheets; or smooth-surface applications or coatings.2
G.	Asphalt Shingle: Composed of a base material, either organic felt or glass fiber mat; asphalt; and
surfacing material, generally in the form of mineral granules.3
H.	Metal Roof Component: Metal roof product designed to resemble a traditional steep-slope
residential product such as shingle, tile, shake, or slate.
I.	Metal Roof Panel: 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
loads. Standing seam roofs can be used on roofs with slopes as low as %:12. Steel and
aluminum sheets are commonly used to fabricate metal roof panels. Steel requires a corrosion
resistant metal coating such as zinc, aluminum, alloys of zinc-aluminum, or tin. Metallic coated
steel includes galvanized steel, aluminized steel, zinc-aluminum-coated steel and terne-coated

steel. Metallic coated steels may also be painted to provide additional corrosion protection, as well
as color.
J. 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.4
K. 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 include 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.
Note: The definition for Roof Coating has been expanded to include epoxy based roof coatings and
other formulations that are applied in a liquid state to the roof surface.
L. Roof Tile: May be composed of clay, concrete, fiber-cement, or synthetic materials. A variety of
tile profiles, styles, finishes, and colors are available.
M. Single-Ply 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.5
N. Spray Polvurethane Foam Roof System: 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.
O. Variegated Roof Products: A material with a varied surface color, requiring a larger sample for
measurement of Solar Reflectance.6
Roof Product Performance
P. Solar Flux: The direct and diffuse radiation from the sun received at ground level over the solar
spectrum expressed in watts per square meter.
Q. Solar Reflectance: The fraction of solar flux reflected by a surface expressed as a percent or
within the range of 0.00 and 1.00.
R. Solar Spectrum: Radiation originating from the sun, including ultraviolet, visible, and near-infrared
radiation. Approximately 99 percent of solar energy lies between wavelengths of 0.3 to 3.5
micrometers (Fm).
S. Thermal Emittance: The ratio of the radiant heat flux emitted by a sample to that emitted by a
blackbody radiator at the same temperature (Total Thermal Emittance).7
2) Qualifying Products: Any roof product, as defined in Section 1 above, is eligible for ENERGY STAR.

Emissivity Reporting Requirement: Manufacturers are required to report initial emissivity results using
the new Version 2.0 Qualifying Product Information (QPI) form. Manufacturers must use one of the test
procedures listed below when measuring emissivity:
¦	ASTM C1371-04a - Standard Test Method for Determination of Emittance of Materials Near
Room Temperature using Portable Emissometers
¦	ASTM E408-71(1996) e1 - Standard Test Method for Total Normal Emittance of Surfaces Using
Inspection-Meter Techniques.
ENERGY STAR Version 2.0 Program Requirements for Roof Products: Revised Final Draft

-------
Note: Following the release of the Draft 1 specification, many stakeholders continued to have concerns
about EPA's proposed emissivity requirement. In particular, they questioned the applicability and cost
effectiveness of a national requirement due to extreme differences in regional climates across the U.S.
Based on several industry discussions and review of data made available through various resources,
including the DOE Cool Roof Calculator, EPA has decided that more time is needed to assess whether
an emissivity requirement is appropriate. Therefore, all references to emissivity and Solar Reflectance
Index (SRI) have been removed from this Version 2.0 specification.
However, because emissivity remains an important consideration, particularly in cooling dominated
regions of the U.S., EPA will begin collecting and posting initial emissivity values on the ENERGY STAR
qualified product list. Starting October 31, 2007, the effective date of this Version 2.0 specification,
manufacturers will be required to report initial emissivity results for newly submitted and already
qualified products using the new Version 2.0 QPI form. In combination with the emissivity data, EPA
will post information on the ENERGY STAR Web site that explains the benefits and potential savings of
emissivity, based on geographic location. In drafting the educational content, EPA may seek review by
researchers and industry experts. Manufacturers are encouraged to submit with their comments
any ideas regarding existing sources for clear and accurate information on this subject.
EPA will continue to follow research efforts and state energy efficiency initiatives regarding emissivity and
may decide to revisit the specification if new data or research is presented that clearly supports a specific
emissivity level that is applicable nationwide.
4) Test Criteria: Manufacturers are required to perform tests and self-certify product models that meet the
ENERGY STAR guidelines. Partner agrees to follow the test methods as outlined below. Alternatively,
a Partner already participating in the Cool Roof Rating Council (CRRC) Product Rating Program8 may
submit solar reflectance and thermal emittance product information derived from CRRC certification.
Please note, at the time that this document was written the CRRC Product Rating Program had not
yet produced results for maintenance of solar reflectance. Therefore Partners shall either wait until
these results are available to submit product information, or use one of the test procedure options
listed below to derive values for the maintenance of solar reflectance.
Test results must be reported to EPA using the Roof Products QPI Form. Only completed QPI forms
will be accepted. QPI forms indicating that data is pending will not be accepted. Documentation of
test results, e.g., test reports, in either hard copy or electronic format, must be submitted to EPA along
with the QPI Form for each qualifying product. Note: Supporting documentation must include the test
results of all required samples in addition to providing the final average test results for ENERGY STAR
qualification.
Initial Solar Reflectance
Product shall be tested using ASTM E 903 - Standard Test Method for Solar Absorptance,
Reflectance, and Transmission of Materials Using Integrating Spheres. Products need only be tested
for solar reflectance (values for solar absorptance and transmission need not be obtained).
Manufacturers will submit a 3" X 3" flat sample of each product to a laboratory that has the appropriate
equipment. The manufacturer shall request that the test be performed using a black background for
the sample. Where appropriate, the sample shall be prepared according to manufacturer
recommendation for thickness used in the field.
Product may also be tested using ASTM C 1549 - Standard Test Method for Determination of Solar
Reflectance Near Ambient Temperature Using a Portable Solar Reflectometer.
Variegated roof products may also be tested according to the CRRC Test Method #1,9
If Partner has changed a fundamental element of product formulation such as the base latex, Partner

must retest for the solar reflectance of the product both initially and according to the Maintenance of
Solar Reflectance (see next section). In addition, to ensure other product formulation changes will not
affect the solar reflectance of the product, Partner shall certify that the product formulation or recipe
has not changed since the solar reflectance testing was performed.
Maintenance of Solar Reflectance
Partner shall use one of the following methods to test the maintenance of solar reflectance of a roof
product. NOTE: The test surface of each sample shall not be washed, cleaned, or wiped in any
fashion. Loose dirt, embedded dirt, environmental stains, mold, mildew, and any other material that
rests on - or has become incorporated into - the surface of the material shall not be altered. For
existing products qualified under version 1.0 of the roof products specification, retesting on uncleaned
samples is not required. These products will be denoted in some manner on the ENERGY STAR
qualifying product list as having been tested on clean samples.
A) Identify three (3) existing roofs on which the same product was installed a minimum of three years
prior. At least one of these existing roofs must be located within a major metropolitan area such as
Atlanta, Boston, Chicago, Dallas, Houston, Los Angeles, Miami, Minneapolis, New York, Philadelphia,
San Francisco, St. Louis, Washington D.C., etc. The roof product need not have been installed at the
same time on the three buildings; however, the roofs must each be at least three years old.
Note: EPA is continuing to require that roof surfaces not be cleaned prior to testing for maintenance of
solar reflectance. Although manufacturers may provide recommendations regarding routine cleaning,
roofs are rarely cleaned after installation. The purpose of requiring data from uncleaned samples is to
provide end users with more realistic product performance information under a typical use scenario. EPA
will retain a list of previously qualified ENERGY STAR roof products that were cleaned during testing on
its Web site.
1)	For low-slope roof products and coatings, use either ASTM E 1918 - Standard Test Method for
Measuring Solar Reflectance of Horizontal and Low-Sloped Surfaces in the Field or ASTM C
1549, to test the solar reflectance of the roof product as installed and weathered for three years.
Partner shall divide the roof into at least ten (10) equal sections. Measurements shall be
performed in the center of each area. At least three (3) repetitions shall be made of each
measurement (the exact same area). Note that if a pond or birdbath occurs in the center of the
area to be measured, offset the measurement location so that it is outside of the pond or birdbath.
Partner shall take the average of all solar reflectance values obtained from the roof to determine if
the solar reflectance of the roof product as installed and weathered for three years is greater than
or equal to the threshold value in Table 1. If Partner is employing ASTM E 1918, the test must be
performed on a clear day (no clouds) between 10:00 AM and 2:00 PM when the sun is high in the
sky and there can be no obstruction in the field of view.
2)	To measure the solar reflectance of steep-slope roofs as installed and weathered for three
years, use ASTM C 1549. Partner shall divide the roof into at least ten (10) equal sections.
Measurements shall be performed in the center of each area. At least three repetitions shall be
made of each measurement. Partner shall take the average of all solar reflectance values
obtained from the roof to determine if the solar reflectance of the roof product as installed and
weathered for three years is greater than or equal to the threshold value in Table 2.
B)	Take a minimum of three (3) samples from the each of the existing roofs as identified above. At
least three (3) measurements of solar reflectance are to be taken from different areas on each sample
using either ASTM E 903 or ASTM C 1549. Partner shall take the average of all solar reflectance
values obtained from the panels to determine if the solar reflectance of the weathered roof product is
greater than or equal to the threshold values in Tables 1 and 2. Subsequently, the Partner is
responsible for ensuring that the roof from which samples were taken is properly repaired so as to
resume watertight integrity.
C)	Expose panels outdoors on commercial or private weathering farms that are accredited to ISO/IEC
17025:1999 General Requirements for the Competence of Testing and Calibration Laboratories. The
panel must be prepared such that the surface to receive solar radiation goes over the intended
ENERGY STAR Version 2.0 Program Requirements for Roof Products: Revised Final Draft	7

-------
substrate10. At least three (3) panels with the identical formulation as those that were tested for initial
solar reflectance must be exposed for three years in accordance with ASTM G 7 - Standard Practice
for Atmospheric Environmental Exposure Testing of Nonmetaiiic Materials. Each exposure panel must
be at least 24 square inches (155 square centimeters) in size, e.g. 4" x 6" or 3" x 8", and must be
mounted so that there is no run off from one panel to another. To further avoid runoff onto samples,
where possible, the exposure panel should be mounted near the top of the test rack.
At least three (3) measurements of solar reflectance are to be taken from different areas on each
weathered panel using either ASTM E 903 or ASTM C 1549. Partner shall take the average of all
solar reflectance values obtained from the panels to determine if the solar reflectance of the
weathered roof product is greater than or equal to the threshold values in Tables 1 and 2.
1)	For low-slope roof products and coatings and for product that can be applied to either low-slope
or steep-slope roofs, Partner shall use test samples exposed at a slope of 2:12 or less (1/4:12 is
recommended) and facing south.
2)	For steep-slope roof products and coatings, Partner shall use test samples exposed at a slope
between 2:12 and 12:12 (4:12 is recommended) and facing south.
Note: In the case that an ASTM test procedure expires, due to the ASTM committee's failure to revise
it within an 8-year period, manufacturers will use the most recent version of the test procedure for
purposes of testing roof products under this specification.
5) Effective Date: The date that manufacturers may begin to qualify products as ENERGY STAR will be
defined as the effective date of the agreement. The ENERGY STAR Roof Products Specification
(Version 2.0) shall go into effect on October 31, 2007. Any previously executed agreement on the
subject of ENERGY STAR qualified roof products shall be terminated effective October 30, 2007.
Qualifying Roof Products under Version 2.0: All products, including models originally qualified under
Version 1.0, with a date of manufacture on or after October 31, 2007, must meet the new (Version
2.0) requirements in order to qualify for ENERGY STAR. The date of manufacture is specific to each
product and is the date (e.g., month and year) of which a unit is considered to be completely
assembled.
Note: EPA has spent the last several months meeting with several stakeholders and reviewing
industry supplied comments and performance data, particularly with regard to the previously
proposed emissivity requirement. As a result, the effective date has been moved from May 1 to
October 31, 2007. With the removal of the emissivity requirement and SRI alternative, EPA does not
anticipate any further delays and considers this date to be final.
6) Future Specification Revisions: ENERGY STAR reserves the right to change the specification should
technological and/or market changes affect its usefulness to consumers, industry, or the environment.
In keeping with current policy, revisions to the specification are arrived at through industry
discussions. In the event of a specification revision, please note that the ENERGY STAR qualification
is not automatically granted for the life of a product model. To qualify with the energy efficiency
criteria of ENERGY STAR, a product model must meet the ENERGY STAR specification in effect on
the date of manufacture.
10 For example, if a coating is intended for BUR, the specimen set needs to be prepared using BUR. If the coating is
to be used over Modified Bitumen, a specimen set needs to be prepared using Modified Bitumen.
