ENERGY STAR Roof Coatings: Eligibility and Certification
The ENERGY STAR label for roof coatings is administered by the U.S. Environmental Protection Agency and identifies products meeting defined solar reflectance and thermal emittance thresholds. Certification carries practical consequences: it affects eligibility for federal tax credits, procurement compliance under federal acquisition rules, and building code credit pathways under standards such as ASHRAE 90.1. The Roof Coating Listings within this directory cross-reference ENERGY STAR status as one of the primary qualification markers for commercial and residential coating products.
Definition and scope
ENERGY STAR roof coatings are coating products — applied liquid membranes, reflective coatings, and elastomeric systems — that satisfy the minimum performance criteria established by the U.S. EPA ENERGY STAR Roof Products Program. The program covers both steep-slope and low-slope roofing products, with distinct thresholds for each category.
The scope of the ENERGY STAR roof products label is limited to the radiative performance of the finished surface. It does not certify structural integrity, fire resistance classification, or wind uplift resistance. Those properties are addressed by separate rating bodies — FM Approvals for assembly-level listings and UL for fire and wind classifications.
Eligibility is restricted to products that are third-party rated through the Cool Roof Rating Council (CRRC) Rated Products Directory. CRRC conducts laboratory testing under protocols aligned with ASTM standards and assigns initial and aged solar reflectance and thermal emittance values. Products must maintain CRRC ratings in good standing to carry the ENERGY STAR mark.
How it works
The certification pathway follows a structured sequence:
- CRRC laboratory rating: The manufacturer submits samples for testing under CRRC's rated products program. Initial solar reflectance and thermal emittance values are measured, then aged values are determined after accelerated weathering equivalent to three years of exterior exposure.
- ENERGY STAR threshold comparison: The EPA compares the CRRC-rated aged values against published minimum criteria (ENERGY STAR Key Product Criteria – Roof Products). For low-slope applications (pitch ≤ 2:12), the minimum aged solar reflectance is 0.55 and minimum aged thermal emittance is 0.75. For steep-slope applications (pitch > 2:12), the minimum initial solar reflectance is 0.25, with no separate thermal emittance floor.
- Manufacturer agreement: The manufacturer signs a partnership agreement with the EPA authorizing use of the ENERGY STAR mark on qualifying products.
- Ongoing verification: ENERGY STAR requires periodic reverification testing. Products that fail to maintain CRRC ratings, or whose manufacturers do not submit required renewal documentation, are delisted from the EPA ENERGY STAR Roof Products database.
The distinction between low-slope and steep-slope thresholds is not arbitrary. Low-slope roofs — dominant on commercial and industrial buildings — present larger horizontal surface area exposed to direct solar gain. The higher reflectance floor for that category reflects the proportionally greater cooling load impact documented in DOE research on urban heat islands and building energy consumption.
The Cool Roof Rating Council (CRRC) functions as the independent testing and rating infrastructure that ENERGY STAR depends on. CRRC operates under ASTM D7814 and related test methods; its ratings are also cross-referenced in California's Title 24 Building Energy Efficiency Standards and in model code language adopted by the International Energy Conservation Code (IECC).
Common scenarios
New commercial roof coating application: A building owner applying a silicone or acrylic coating to a flat commercial roof selects an ENERGY STAR-certified product to comply with local code requirements that reference ASHRAE 90.1-2019. ASHRAE 90.1 includes a prescriptive cool roof compliance path that cites CRRC ratings; ENERGY STAR certification provides documented evidence that the product meets or exceeds those values.
Federal facility procurement: Federal agencies operating under Executive Order 13693 (the predecessor framework for sustainable federal operations) and General Services Administration procurement guidelines favor or require ENERGY STAR-certified roof products on covered projects. A roof coating contractor bidding on a federal building project must confirm ENERGY STAR status in the submittal documentation.
IRS residential energy credit qualification: Under the Inflation Reduction Act (IRA) provisions, certain residential energy efficiency improvements qualify for the IRS Section 25C residential energy efficiency tax credit. Roof products must meet ENERGY STAR requirements to qualify. For homeowners on steep-slope roofs, the 0.25 initial solar reflectance threshold is the applicable eligibility floor.
Re-roofing permit documentation: Permitting jurisdictions that have adopted the 2021 IECC or later require documentation of roofing product performance for certain building categories. An ENERGY STAR certification letter or CRRC product ID number satisfies the inspector's documentation request without requiring the applicant to submit raw test data.
Decision boundaries
Not every reflective coating qualifies, and not every qualified product is appropriate for every application. The classification boundary between low-slope and steep-slope thresholds creates a practical split: a product rated only to the steep-slope threshold (initial solar reflectance ≥ 0.25) does not satisfy the low-slope ENERGY STAR criteria and cannot be substituted in a commercial flat-roof compliance pathway.
A coating product carrying ENERGY STAR certification does not automatically satisfy air quality regulations. The South Coast Air Quality Management District's Rule 1113 limits VOC content in architectural coatings independently of reflective performance. A product must meet both sets of requirements to be fully compliant in jurisdictions under that district's authority.
ENERGY STAR certification covers the coating product as formulated and tested. Field application conditions — surface preparation failures, substrate contamination, improper mil thickness — are outside the scope of the certification and can produce in-service reflectance values substantially below rated levels. Inspection documentation verifying application thickness is a separate requirement under many commercial project specifications and has no direct relationship to the EPA certification status.
The Roof Coatings Manufacturers Association (RCMA) publishes application guidance and technical bulletins that address the gap between certified product performance and installed performance. For professionals navigating the range of certified products available, the roof-coating-directory-purpose-and-scope page explains how listings in this reference are structured and what certification markers are tracked across the directory's coverage area.
The distinction between an ENERGY STAR-certified coating and a CRRC-rated (but non-ENERGY STAR) coating matters in procurement contexts: CRRC-rated products that fall below ENERGY STAR thresholds may still satisfy some state energy code prescriptive paths but cannot be marketed with the ENERGY STAR label or used for IRS credit claims. Understanding how those two rating systems interlock is foundational to reading the how-to-use-this-roof-coating-resource page, which maps those distinctions across the directory's classification framework.
