What Gaco just published
Gaco‑Western entered the transparency arena with a set of product‑specific Environmental Product Declarations covering core roof coating lines. The debut includes GacoFlex S2000, S2100, S4200, and GR1600 silicone coatings plus the A4700 and A4800 acrylic systems. All were published in November 2025 and verified through Smart EPD as the program operator. The EPD development is listed to Gaco‑Western, signaling an in‑house lift rather than a third‑party consultant.
Scope that matters to specifiers
These are product‑level EPDs, not a generic brochure. The portfolio spans both silicone and acrylic maintenance and restoration use cases, with at least one system declaration for A4700 that reflects primer plus topcoat configurations. That mix mirrors how roof coating work is actually specified across metal, BUR, modified bitumen, SPF and aged single‑ply surfaces.
Who Gaco is and why this move lands now
Gaco‑Western manufactures roof coatings, deck systems, and waterproofing for commercial and institutional owners who want to extend service life without full tear‑offs. Their products show up when teams need reflective, durable membranes that install quickly. Publishing EPDs gives design teams verified numbers to drop into whole‑building LCA tools so Gaco options can compete on performance, not just price.
Program operator choice
Verification and publication run through Smart EPD, a digital‑first operator widely used in North America and aligned to EN 15804 and ISO 14025 practices (EPD Guide, 2025). For manufacturers, operator fit shapes timeline and market recognition, which is why roofing brands often default to operators that buyers already check.
Work for Gaco‑Western or competing against them?
Follow us for a product-by-product analysis of Gaco’s EPDs and see how they stack up against GAF and Carlisle in winning specs.
Competitive snapshot
GAF already brings roof‑coating EPDs to the table, including an Acrylic Top Coat and the Premium Acrylic HydroStop system verified by NSF with current five‑year windows [NSF, 2024]. That means GAF reps can walk into design‑assist meetings with coating, membrane, and insulation disclosures in one folder, a playbook they have showcased for a while (EPD Guide: Tremco & GAF Playbook, 2025).
Carlisle Coatings & Waterproofing lists coating EPDs in adjacent categories like water‑resistive and air barriers through NSF. Those are useful for envelope packages, yet they are not roof‑coating declarations per the roof‑coating PCR. That leaves room on purely roof‑restoration bids where a product‑specific coating EPD can be the decider.
Johns Manville’s roofing declarations are strong across membranes and cover boards through UL and NSF. Coating‑specific EPDs are less visible in public libraries, so the battle for acrylic and silicone restoration specs still comes down to who shows a product‑specific roof‑coating EPD on submittal day.
Why this changes the bid math
On projects tracking carbon, a product without a product‑specific EPD often drags a conservative penalty in LCA tools, which quietly downgrades its chances. Having coating EPDs removes that handicap. It also lets owners compare apples to apples across silicone and acrylic options, plant footprints, and formulation choices. One verified number beats five pages of adjectives.
PCR fit and comparability
Gaco’s declarations cite the roof‑coating PCR commonly used in North America, which is a good signal for comparability in the category. The rulebook is the Monopoly rulebook of LCAs. Ignore it and the game falls apart. Matching the prevailing PCR across competitors is how you get fair reads in bid software and databases.
Visibility check on Gaco’s site
We looked for a central EPD listing on gaco.com and did not find one at the time of writing. That makes these new assets harder for reps and architects to pull mid‑bid. Visibility matters, so pinning EPD PDFs and digital records to product pages and a sustainability hub is the next best step. It is a small web task that pays off every single RFQ, definately.
The takeaway
Gaco‑Western now has the rookie card that counts. With product‑specific EPDs across its flagship silicone and acrylic coatings, it can go toe‑to‑toe on restoration specs where GAF already had coating EPDs in market [NSF, 2024]. Expect tighter shortlists and fewer default swaps when carbon is on the scoring sheet. The fastest wins come when teams make the EPDs easy to find, keep them current, and align future waves to the same PCR so the comparison stays clean.
