        deck board overlap Sign In/Join 
        posted
        I am installing a new deck surface and wonder about having the board ends overlap the rim joist. I have seen decks with anywhere from no overlap to up to 2" overlap.

        Any comments would be appreciated.

        I would cut them flush with the rim joist and then use a 1x3 or 1x4 to cover the cut ends. It makes for a cleaner look.

        It really depends on what you like. most often on pressure treated decks, we have a 1" or so overhang. Composite decking can be had with matching edge trim so you cut it flush then add the trim.

        Structurally it doesn't make any difference which style you go with.

        I do it with about a 1 inch overhang all the way around, not just the ends. It's kind of like the 'drip edge' of a countertop -- you don't want dripping water to damage what is below the top. Let the water drip to the ground. I recently did a repair for a guy on his deck where the Trex was not over hanging and the water was rotting the lumber below. But there is more than one way to do things.

        I use about 1 to 1-1/2" on my decks. I usually don't try to cut them exact when installing but let them run wild. I later come back and measure uniformly on each end and snap a chaulk line. Then use a circular saw to cut them off. That way your overhang is consistant.
