Tilcor Roofing: products, EPDs, and the spec gap
Tilcor is a focused stone‑coated steel roofer with a catalog that hits the sweet spot for pitched roofs. The product story is strong. The EPD story is mixed. Their last product‑specific EPD is now past its validity window, which can quietly nudge them out of shortlists when projects expect current, third‑party verified disclosures. Here is where Tilcor stands, how it stacks up against common alternatives, and the fastest path to get fully specification‑ready again.
Who Tilcor is and what they sell
Tilcor (tilcorroofing.com) specializes in stone‑coated steel roofing systems for pitched roofs. Profiles span Mediterranean‑style tiles, shake, shingle, and low‑profile slate looks, supported by accessories and vents. This is a pure‑play roofing manufacturer rather than a diversified building‑products conglomerate, which keeps the product line tight and easy to navigate.
Product range at a glance
Across the profile families and colorways, the commercial assortment lands in the dozens of SKUs, not hundreds. That breadth is enough to cover most residential and light‑commercial aesthetics without fragmenting volume. If you spec roofs for education, hospitality, or mixed‑use with sloped sections, you will usually find a match in their line.
EPD coverage today
Tilcor published a product‑specific EPD for “Pressed and Coated Metal Roofing System Tiles” with UL on October 1, 2020, valid five years. That means it expired on October 1, 2025 (Tilcor EPD, 2020) (Tilcor EPD, 2020). Teams pursuing LEED v5‑ready material transparency, public procurement preferences, or owner policies that call for current Type III EPDs may treat an expired declaration as insufficient. It’s a small miss, but it matters comercially.
Likely best sellers, and where the gap shows up
CF Shingle and Antica style tiles are frequent picks for pitched residential and campus buildings. When those projects ask for an in‑date EPD, design teams look for substitutes that keep the look or the performance while checking the paperwork box. Many standing‑seam and roll‑formed metal roof panel manufacturers point to an industry‑wide EPD from the Metal Construction Association that is current and acceptable on many jobs, even if it is not product‑specific (MCA, 2025) (MCA, 2025). That keeps them specification‑eligible while a stone‑coated alternative without a current EPD may face a hurdle.
Main competitors Tilcor meets on projects
- Stone‑coated steel peers: DECRA and Unified Steel (Westlake Royal Roofing Solutions) often appear in the same bids. Their public sites emphasize performance and weather approvals; if one of them fields a current EPD before others, they gain an easy filter advantage with procurement.
- Other metal options: standing‑seam systems from brands like McElroy Metal or Englert show up when aesthetics allow a panel look. Many of these manufacturers leverage the MCA industry‑wide EPD noted above (MCA, 2025).
- Non‑metal substitutes: asphalt shingles remain common in residential, while single‑ply systems dominate low‑slope sections on education and light‑commercial. Large brands such as GAF list multiple current product‑specific EPDs for membranes and related components through NSF’s directory, valid through 2028–2029 (NSF, 2025) (NSF, 2025).
Why a current EPD changes shortlists
Procurement teams juggling LEED v5 targets or owner ESG screens often prefer products that come with verified, current EPDs. Without one, they must default to conservative emission factors that can penalize a specification, which naturally tilts the table toward competitors with paperwork in hand. The result is fewer at‑bats and more price pressure when you do make the cut.
What “good” could look like
Tilcor’s 2020 document already framed the right scope and PCR family for metal roof panels. A refreshed, product‑specific EPD that consolidates representative tiles by coating group (stone‑coated, satin) keeps the bill of materials and process data tight while maximizing SKU coverage. Pair that with a short addendum strategy for regional plants as needed, and the catalog can be largely covered in one sprint (UL, 2020) (Tilcor EPD, 2020).
Fastest path to close the gap
- Confirm the reference year and production boundaries that mirror the prior EPD, then pre‑pull utility, coatings, scrap, and transport data from ERP and QA logs.
- Reuse the previous PCR alignment for roof and wall panels, validate any PCR revisions, and select the program operator that matches target markets.
- Publish a representative EPD for each coating group, map product SKUs to each, and socialize the cut‑sheets with sales so bids stop getting flagged for missing documentation.
Sustainability story, in their words
Tilcor publicly leans on recycled steel, above‑sheathing ventilation, and potable run‑off testing as part of its sustainability narrative. If you want to see how they frame it for North America, it is here: Tilcor Sustainability.
Bottom line for specifiers
The products are credible, proven, and cover the common looks that owners ask for. The missing piece is a current EPD. Refreshing the 2020 declaration now removes an avoidable filter on LEED v5‑minded projects and keeps stone‑coated steel in play beside standing‑seam and other roof systems that already point to active disclosures (MCA, 2025) (MCA, 2025; NSF, 2025) (NSF, 2025).
Frequently Asked Questions
Does Tilcor currently have an active, product‑specific EPD for its stone‑coated steel tiles?
No. Tilcor’s last product‑specific EPD, issued October 1, 2020 with a five‑year validity, expired on October 1, 2025 (Tilcor EPD, 2020).
Will an industry‑wide EPD satisfy projects that ask for EPDs?
Often yes for the basic requirement, although product‑specific EPDs can be preferred or score higher in owner or rating‑system rubrics. Metal roof panel makers commonly rely on the MCA roll‑formed cladding EPD that is current as of 2025 (MCA, 2025).
Which competing roof products commonly show current EPDs?
Single‑ply membranes and related roofing components from large brands such as GAF have multiple active, product‑specific EPDs listed with NSF through 2028–2029, which keeps them spec‑ready on low‑slope work (NSF, 2025).
