Chevron deck pattern — mitered V-arrows

Chevron uses MITERED boards meeting at a perfect 90° angle at a center seam — boards have angled ends that align in a clean continuous V. Herringbone uses SQUARE-ENDED boards meeting at 90° with their ends offset (one board butts the side of the next). Visually: chevron reads as clean arrows pointing up the deck; herringbone reads as interlocking L-shapes. Chevron is harder to cut precisely; herringbone is harder to lay out.

Because the seam runs the entire length of the deck as a single continuous line. Any gap, misalignment, or off-angle miter is visible from across the yard for the full deck length. A 1/16″ gap multiplied across 10 ft of seam reads as a defect. Chevron is the most cut-precision-demanding common deck pattern — pros typically build a jig to ensure every miter is exactly 45.00°. DIY chevron is achievable but requires premium tools (sliding compound miter saw with laser guide).

Material: ~20% waste factor — better than herringbone (25%) because boards are longer (less offcut accumulation). Labor: ~2.5× straight pattern because every board needs precise 45° miters at both ends. For a typical 16×12 deck: ~$400-700 extra materials, ~$1,000-1,800 extra labor. Total premium: ~$1,400-2,500 over straight pattern. Higher than herringbone in labor, lower in material.

Yes — and in fact composite is BETTER suited for chevron than wood because cut ends are dimensionally stable (don't expand/contract differentially with humidity, which would open seam gaps over time on wood). Use square-edge composite for chevron — grooved-edge boards show the groove on the angled cut faces. Premium composite manufacturers (Trex Signature, TimberTech Reserve, AZEK Vintage) publish chevron-compatible product lines with sealable end-cuts.

Medium decks 10×12 to 14×16 are the sweet spot. On smaller decks (under 8×10) the pattern doesn't have enough length to show the V arrow effect properly. On larger decks (16×20+) the center seam length compounds cut tolerance issues — any 1/32″ error per board accumulates over 20+ boards into a visible misalignment. Mid-size decks let the pattern shine without overwhelming cut precision requirements.

Yes — joists must run PARALLEL to the center seam (i.e., perpendicular to the house wall, same as a normal deck, with the seam down the middle of the deck length). Each chevron board then bears on multiple joists. If you tried to run joists perpendicular to the seam, half the boards would have minimal joist support. Plan your framing layout before deciding on chevron orientation.

Subjective, but here's the math: chevron adds ~$1,400-2,500 over straight on a typical mid-size deck. Real estate appraisers consistently value chevron decks at +$3,500-6,000 over equivalent straight decks at resale because the pattern reads as custom-built luxury. ROI is positive if you're building a forever home, marginal-to-positive if you plan to sell within 5 years. Most buyers building chevron do it for the look + don't calculate ROI.
