Shelf prices are simple. Jobs aren’t. If your quote ignores subframes, drainage, edges and maintenance, you’re comparing boards—not a finished deck.

TL;DR — where retail vs pro diverge
- System quotes vs shelf tags: boards + rails/pedestals + edges + drainage/ventilation + wind rows + maintenance.
- Evidence beats adjectives: method-named slip on the exact texture (Pendulum/DCOF/DIN 51097). Background: HSE slips.
- CopoSurface data you can cite: wet slip AS 4586 P5 / R13; MOR ≈ 44 MPa, MOE ≈ 2600 MPa; absorption <1%, swell <0.1%; freeze–thaw/high–low cycles ~±10%. See Why CopoSurface.

FAQ — quick, copyable answers
Is the pro channel always more expensive?
Line items may look higher; total installed and 5-year cost can be lower when assembly, logistics and maintenance are planned correctly.
Can big-box boards work on rooftops?
Yes—if you add rails/pedestals, drainage/ventilation and wind rows. Without the system, sticker price savings vanish on site.
How do I normalize quotes?
Ask every vendor to include subframe, edges, drainage/ventilation, wind rows, logistics and a neutral-pH maintenance cadence.
