Too late to screw down IPE decking?
I had to pull up ipe on our roof deck in order for roofers to do some checking/work over the past few weeks. The deck is about a year and a half old and is not treated. My question is should I wait to screw the boards down again onto the pressure treated sleepers (really just long strips of pressure-treated wood that were cut on an long angle to compensate for roof slope) or is it fine to screw down the boards in the current 32-38 degree weather we are having here in Brooklyn, NY? The boards are 1x6 and were screwed down every 18 inches.
Also we waited a year to let the wood 'season' and were planning to treat it in the spring. What type of prep would people recommend for decking which has been exposed for this long?
Any advice would be appreciated. Like others I have also found these forums invaluable!
