How we calculate
The Trex Signature Calculator is the brand-deep estimator for Trex Signature — Trex's 2024 flagship decking line that sits above Transcend at the top of the lineup. Signature carries Trex's longest warranty (35-yr structural + 35-yr fade & stain), the most realistic hardwood-grain multi-tonal cap Trex has shipped, and a six-color palette focused on premium aesthetic: Whidbey (cool weathered driftwood), Aspen (light premium oak), Helios (sun-bleached warm), Maverick (rich mid-brown w/ streaking), Iron Bluff (deep gray w/ hardwood grain), and Carbonized (darkest, heat-mitigation cap). This calc focuses on Signature with Transcend and Select as comparison anchors so you can see exactly what the Signature premium costs on your specific deck. TUHF + Cortex fasteners, Signature aluminum railing, optional RainEscape and DeckLighting. 2026-Q1 retail.
Per-LF retail prices reflect 2026-Q1 Trex Signature pricing at Home Depot + TrexPro Platinum channel. TUHF + Cortex specs from Trex install manuals. 35-yr structural + 35-yr fade & stain warranty per Trex Signature published terms (2024 launch). Color palette + heat ratings from Trex 2024 color guide.
Rows = ceil(width × 12 ÷ (5.5 + 0.125)) — Trex face is 5.5″ with 1/8″ install gap. Waste % is pattern-driven.
Each TUHF box ships 90 clips and covers ~50 sqft at 16″ joist on-center. Total clips = boards × (length × 12 ÷ 16 + 1).
Signature is $6.40/lf vs Transcend $5.40/lf — a $1.00/lf premium. On a 400 lf project that's $400 more in materials. The premium buys 10 more years of warranty (35 vs 25) plus a more realistic hardwood cap.
Signature installs are 25% slower than face-screwed PT (TUHF clip-system sequencing). Pattern + shape multipliers compound.
Over the warranty life, Signature's higher upfront cost amortizes across 35 years vs Transcend's 25. Annual amortized cost is often LOWER for Signature when you factor the 10-year-longer warranty life.
