Can you use Pinnacle subflooring on a roof?


Is your Pinnacle Subflooring suitable for roof applications?

Thank you for the email Eric. I assume you are referring to a pitch roof with typical rafter/truss spacing. It will make a very strong roof for sure and if you proceed I recommend you install the panels with the groove facing the eve as that would reduce the chances of moisture getting trapped in the groove. You would, of course, still need to space the square edges 1/8″, cover the roof as quickly as you can, and you may need to use longer nails to accommodate the thicker panels. If this is a flat roof with wider spacing of the supports please refer to your designer, code official, or architect to ensure the dead loads are within the roof system capabilities.
