Why roofing EPDs vary by system type
"Roofing" covers several fundamentally different systems rather than one product family — single-ply membranes, asphalt shingles, built-up and modified bituminous systems, and metal roofing are installed differently, last different service lifespans, and are manufactured through unrelated processes. Each has traditionally been covered by its own PCR, so an EPD for one system type says little about another, even when both end up on the same building type.
Key materials typically covered
"Roofing" EPDs span several distinct system types, generally declared separately:
- Single-ply membranes — TPO, EPDM, and PVC roofing membranes
- Asphalt shingles — the most common residential roofing product
- Built-up and modified bituminous roofing — layered asphalt-based systems
- Metal roofing and cladding — a distinct material category from membrane or shingle systems
- Roof cover boards — installed beneath the membrane, declared separately from it
Key standards and PCRs
In North America, the Single-Ply Roofing Membranes PCR and the Asphalt Shingles, Built-up Asphalt and Modified Bituminous Membrane Roofing PCR — both hosted by NSF International — cover the two largest roofing-system categories separately. In Europe, roofing products fall under EN 15804. See Product Category Rules for how to confirm the current, applicable PCR for a specific roofing system.
Top EPD program operators for Roofing
Roofing EPDs concentrate around a small set of program operators:
- NSF International — hosts the largest share of roofing EPDs in North America, across both single-ply membrane and bituminous system PCRs
- UL — also active as a program operator for roofing products
- ASTM International — operates PCR and EPD programs covering some roofing categories
- Internationally: EPD International and EPD-Global operate active roofing EPD programs in Europe
Notable producers of Roofing
Major roofing manufacturers — including companies like Sika, a large-scale single-ply membrane producer — have published product-specific EPDs across membrane, shingle, and bituminous product lines. Coverage varies significantly by manufacturer and system type; check a specific producer's own published EPDs rather than assuming coverage.
Sample EPDs for Roofing
To see what an actual roofing EPD looks like, EPD-Global's public registry publishes full documents — for example, Sika Services AG's EPD for the Sarnafil G 410-20 single-ply membrane, searchable by NEPD number. In North America, NSF International lists published membrane roofing EPDs directly.
How to Get a Roofing EPD: Step-by-Step
Getting an EPD for a roofing membrane, shingle, or related product follows the same core process as any other construction product: choosing the applicable system-specific PCR, collecting primary production data, building the LCA, and having it independently verified before publication. See How to Get an EPD: Step-by-Step for the full process.
Frequently asked questions
Is a single-ply membrane covered by the same PCR as asphalt shingles?
No — single-ply membranes (TPO, EPDM, PVC) and asphalt/modified bituminous systems are covered by separate PCRs, reflecting their genuinely different materials and installation methods rather than being variants of one roofing standard.
Who publishes the most roofing EPDs?
NSF International hosts the largest share of membrane roofing EPDs in North America, followed by UL and ASTM International — worth checking which program operator issued a specific EPD, since coverage and update cadence differ between them.
Does roof color or solar reflectivity show up in an EPD?
Not directly — reflectivity and solar reflectance are separate performance metrics, often certified independently (for example through the Cool Roof Rating Council), while an EPD reports embodied-carbon and related environmental impacts rather than thermal performance.
Are roof cover boards declared separately from the membrane above them?
Yes — cover boards (typically gypsum- or wood-fiber-based) are a distinct product category with their own EPDs, separate from the waterproofing membrane installed over them, even though they're always installed together.
Who verifies roofing EPDs?
Predominantly NSF International, given the volume of membrane roofing EPDs it hosts, alongside UL and ASTM International for other roofing system types.
Where can I see an example of a real roofing EPD?
Public EPD registries such as EPD-Global publish full roofing EPD documents — see Sample EPDs below. NSF International also lists published membrane roofing EPDs directly.
