How to use
PRO Reserve (flagship composite, 30-yr structural, premium multi-tonal cap) is the default. Compare against PRO Legacy (mid-tier hardwood streak look) and EDGE Prime+ (value entry, Lowe's stocked). For AZEK PVC instead, use the AZEK Deck Calculator.
Four signature multi-tonal colors — Antique Leather (warm tobacco brown), Driftwood (cool weathered gray), Storm Grey (mid-tone gray), Pecan (golden brown). Each color is grain-printed on the cap for natural-looking variation rather than the uniform color of capped composites.
Length × width in feet. Pattern: parallel (7% waste, 1.0× labor), picture-frame (12%, 1.18×), diagonal 45° (15%, 1.12×). Calculator quantizes board count using TimberTech's stocked 12/16/20 ft.
CONCEALoc hidden-clip is the default — 90 clips/box, $85/box, ~50 sqft coverage at 16″ joist on-center. Cortex (color-matched plug system, 50/pack, $38/pack) is the face-screw alternative.
Premier Aluminum ($175/lf, slimmest sightline), Reserve Composite ($90/lf, color-matched to Reserve decking — natural pair), or Builder Composite ($55/lf, value tier).
AZEK Drink Rail ($45/lf top-mount shelf) and TimberTech Lighting (post-cap + riser LED kit + 100W transformer + low-voltage wiring) are toggles.

Three honest paths. Composite wins the 25-year math for most homeowners, wood wins on upfront cost, and PVC is unbeatable around water. Each card below answers in one glance — recalculate the bill of materials by clicking a brand in the picker above.
How we calculate
The TimberTech PRO Reserve Calculator is the composite-tier deep-cut for homeowners who've decided on the PRO Reserve flagship capped composite. Reserve is TimberTech's premium composite line (one tier below AZEK PVC) — 30-yr structural + 30-yr fade & stain warranty, multi-tonal cap for natural-looking variation, and four signature colors: Antique Leather (warm tobacco), Driftwood (cool weathered gray), Storm Grey (mid-tone gray), and Pecan (golden brown). This calc covers the full TimberTech composite tier — PRO Reserve as the focus plus PRO Legacy (hardwood-streak mid-tier) and EDGE Prime+ (value entry) for side-by-side comparison. You get a real BoM with CONCEALoc clip-box count, optional AZEK Drink Rail, optional TimberTech Lighting, and a 3-line composite-tier auto-comparison. Pricing reflects 2026-Q1 retail from Lowe's Pro + TimberTech AZEK Pro dealer channel.
Per-LF retail prices reflect 2026-Q1 TimberTech composite pricing at Lowe's Pro + TimberTech AZEK Pro dealer channel. CONCEALoc + Cortex specs from TimberTech install manuals. 30-yr structural + 30-yr fade & stain warranty per TimberTech PRO Reserve published terms.
Rows = ceil(width × 12 ÷ (5.5 + 0.125)) — TimberTech composite face is 5.5″ with 1/8″ install gap. Waste % is pattern-driven.
Each CONCEALoc box ships 90 clips and covers ~50 sqft at 16″ joist on-center. Total clips = boards × (length × 12 ÷ 16 + 1).
Composite installs are 25% slower than face-screwed PT (clip-system sequencing). Pattern + shape multipliers compound.
Within the TimberTech composite tier, Reserve is the premium ($5.50/lf), Legacy is the hardwood-streak mid ($4.80/lf), EDGE Prime+ is the value entry ($4.10/lf). All carry the 30-yr structural warranty except EDGE Prime+ (25-yr).
If you're choosing between Reserve composite and AZEK Vintage PVC, run both — AZEK is $7.20/lf vs Reserve $5.50/lf. Over 25 years, the PVC premium ($1.70/lf × ~400 lf = $680) is offset by AZEK's longer warranty (50-yr vs 30-yr) and lower maintenance cost.

PRO Reserve is TimberTech's flagship capped-composite line — a recycled wood-fiber + plastic core with a polymer cap. AZEK Vintage is TimberTech's flagship PVC line — solid PVC with no wood content. Reserve is $5.50/lf vs AZEK Vintage $7.20/lf, but AZEK carries a 50-yr structural + 30-yr fade warranty versus Reserve's 30-yr structural + 30-yr fade. PVC also runs cooler in dark colors. Pick Reserve when budget matters more than warranty length; pick AZEK when you want the longest warranty in residential decking. Both are made by AZEK Building Products.
Four signature multi-tonal colors: Antique Leather (warm tobacco brown), Driftwood (cool weathered gray), Storm Grey (mid-tone gray), and Pecan (golden brown). Each is grain-printed on the cap for natural-looking variation. Reserve uses TimberTech's deepest multi-tonal cap technology, so the color streaking is more visible than on Legacy or EDGE.
$45-75 per square foot installed depending on color + pattern + complexity. A 16×20 (320 sqft) Reserve deck with Reserve Composite railing and 4 stairs lands around $22,500 nationally; the same deck with Premier Aluminum railing and Drink Rail lands around $30,500. Multiply by ~0.92× South or ~1.28× West Coast. Calculator outputs project-low to project-high range.
For most buyers, yes — Reserve has the deeper multi-tonal cap (looks more like real hardwood), the 4-color premium palette (Antique Leather + Driftwood + Storm Grey + Pecan vs Legacy's Mocha + Tigerwood + Espresso + Ashwood), and slightly better impact resistance. The materials premium is about $0.70/lf (Reserve $5.50 vs Legacy $4.80), which on a 320 sqft deck is roughly $225 in materials. The aesthetic upgrade usually justifies the small premium. Legacy is the right pick when you want the dramatic streaked-tropical look that mimics IPE.
TimberTech's hidden-fastener clip system for grooved boards. Each box has 90 clips and covers ~50 sqft at 16″ joist on-center spacing. Box price is $85; loose clips $1.15 each. The clip nests into the board's edge groove and screws into the joist, leaving a clean screw-free surface. Functionally equivalent to Trex's TUHF system but slightly cheaper per box.
TimberTech PRO Reserve carries a 30-year limited residential structural warranty AND a 30-year limited residential fade & stain warranty. Transferable to a future homeowner one-time at no charge. Register at timbertech.com/warranty within 30 days of install for full coverage. Note: that's longer than Trex Transcend's 25-yr fade and matches the longest composite warranties in the industry alongside MoistureShield Meridian's lifetime structural.
Three channels: Lowe's stocks core Reserve colors; Lowe's Pro Desk does full Reserve palette special-order with 1-2 week lead; TimberTech AZEK Pro Dealers (timbertech.com/find-a-pro) carry the complete palette plus Premier Aluminum railing in stock. Pro Dealer lead times are 2-4 weeks but palette access is widest.
Once you set length × width + pattern + fastener + stairs, the calculator prices the exact same deck across all 3 TimberTech composite lines (Reserve, Legacy, EDGE Prime+) using each line's per-LF retail. The side-by-side table shows total range + per-sqft for each. Tap any to switch the calc to that line; the color picker resets to that line's first color. AZEK PVC lines (Vintage / Harvest / Landmark) are excluded — for those use the AZEK Deck Calculator.
Reserve runs warmer than AZEK PVC at the same color tone (capped composite absorbs more solar heat than PVC) but cooler than uncapped composite. The darkest Reserve color (Antique Leather, heat rating 1) measures 155-165°F surface in 90°F full sun. The other three colors (Driftwood / Storm Grey / Pecan, heat rating 2-3) stay 10-20°F cooler. For barefoot-friendly dark decks in hot climates, upgrade to AZEK Vintage in CoolColor variants.
Yes — TimberTech composite is approved for pool deck use as long as the boards aren't permanently submerged (the cap-not-cap edge cuts could absorb water over years). For boat docks or below-waterline applications, switch to MoistureShield Meridian (the only composite ICC-ES rated for water immersion) or stick to PT marine-rated lumber.
