Re: Removing Trex boards
Screws tend to like to snap off, your best bet is to hope that they snap between the wood framing and the trex, rather than just the head snapping off.
There really is no "trick", either the screw will back out or it won't. Probably the best advice is to have plenty of back up, properly sized, driver tips at the ready, and to really clean out the heads of the screws before you start so the driver tip gets a full bite. Use low speed and care when starting the removal, once the screw is loosened, you can increase the drill speed.
For the screws that snap off, you can use pry bars to slide the board over the screw. For the screws that snap off, if you need to save the trex, then use a sawzall to cut the screw between the framing and the trex. If you don't have to save the trex, simply break it off and worry about the screw afterward.
