Porch replacement

Hey guys. I bought my house last year and have slowly been doing repairs and upgrades. Within the next year or so I plan to replace my back porch due to some rotting wood. My initial plan for the porch was to use Trex composite boards. My concern first and foremost is that the wood that is currently on my porch is 3/4 inch thick and the Trex is 1 inch thick. Where the porch meets the house the boards slide under approximately 1/2 inch, and im not sure if this will be an issue. Can i just set the boards up against the house or do they HAVE to slightly be underneath? Also if they do have to theoretically I could use a miter saw to remove some material on the end. My other question is that I've seen many porches in my area use tongue and grove wood for these porches, this one included. Is there any benefit for that? Other than of course nothing can fall through? I was curious if there was any reason I should go with that other than deck boards. So Im just trying to find out what the best coarse of action would be : Trex composite boards Cedar deck boards Or Tongue and groove, submitted by /u/horrorfreak94 [link] [comments]
