Tremco Roofing: products and the EPD gap

Who they are

Tremco Roofing & Building Maintenance is the roofing arm of Tremco CPG, serving education, healthcare, industrial and public owners across North America with products plus service programs that keep roofs in spec and in service. Their corporate sustainability narrative spans bio‑based materials, envelope upgrades, and green roof systems, outlined on Tremco CPG’s sustainability page (Tremco CPG Sustainability).

What they sell

The catalog covers multiple product families and hundreds of individual SKUs. Expect liquid‑applied restoration systems like AlphaGuard PUMA and silicone topcoats, built‑up and modified bitumen accessories and adhesives, single‑ply options under TremPly TPO and TPA, metal‑roof coatings, sealants and primers, plus amenity components for rooftop decks via Bison pedestals and pavers. This is not a pure play. It is a full‑line roofing house with accessories to match.

EPD coverage at a glance

As of December 19, 2025, we could not locate product‑specific EPDs publicly posted for Tremco’s mainstream roofing membranes or liquid systems in the major North American registries architects commonly check. That includes the single‑ply workhorses where EPDs are increasingly expected during design reviews. If a project‑only or region‑specific declaration exists outside public registries, it did not surface in our search.

Sustainability signals that do show up

Several Tremco Roofing products carry the USDA BioPreferred label, including bio‑based coatings and adhesives, which indicates third‑party verified biobased content under a federal program. This is a credible sustainability signal for owners, even if it is not a substitute for a product‑specific EPD.

Where the gap hurts most

Take TremPly TPO as an example. TPO and PVC membranes are frequently compared side by side during submittals. Many direct competitors publish product‑specific EPDs for their core membranes and, in some cases, for related adhesives through well‑recognized program operators like NSF and ASTM. On projects that prefer or require EPDs, a spec team will often shortlist only products with verified declarations, which means a non‑EPD membrane risks being sidelined even when technical performance is solid.

Who they face on most bids

In low‑slope commercial work, the usual line‑up includes GAF for TPO families, Carlisle for TPO and PVC, Sika Sarnafil for PVC, SOPREMA for bituminous and PVC/KEE systems, Elevate for EPDM and TPO, and CertainTeed for SBS torch, cold and self‑adhered systems. All of these brands have product‑specific EPDs available for at least parts of their roofing ranges, especially single‑ply membranes and bituminous systems. That matters in education and healthcare where carbon accounting and procurement policies increasingly shape the spec.

Practical EPD roadmap for Tremco’s mix

If we were prioritizing, we would start with the highest‑volume, most‑compared lines and the products most often substituted on projects.

1. Single‑ply membranes first. Use the common roofing PCR for single‑ply membranes so comparisons land apples‑to‑apples with peers. Target multiple thicknesses where sales volume is concentrated.
2. Liquid systems next. Publish system‑level EPDs for AlphaGuard assemblies that appear most in reroof and restoration specs, then follow with high‑runner silicone topcoats.
3. Adhesives and primers. Where an adhesive locks a system together and shows up on submittal cover sheets, add a concise EPD to keep the entire assembly spec‑able.
4. Data hygiene. Standardize plant utility and formulation data by reference year and lock a repeatable update cadence so renewals are painless. A partner that handles white‑glove data collection across plants saves the internal team weeks and keeps schedules tight.

Commercial stakes in plain view

An EPD does not automatically win a bid. It clears a gate so performance, warranty, and price can be compared on equal footing. Without it, teams often must use conservative default factors in their carbon models, which can nudge a non‑EPD system out of contention. On a competitive reroof program or a new K‑12 bundle, that can be the difference between being carried forward or getting quietly swapped.

The bottom line

Tremco Roofing has the breadth to compete everywhere, from quick‑cure liquids to full single‑ply systems. The public EPD coverage has not kept pace with that breadth. Closing the gap on TPO, TPA and flagship liquid systems would remove a recurring objection in LEED‑oriented and policy‑driven markets and make it easier for design teams to keep Tremco in the spec. It is low‑glamour work, but it pays back quickly when the next district RFP lands. And yes, it really is worth doing right now, not next season.
