Just built my 2 story home.Getting ready to put siding on.I put on my housewrap and then put fanfold over that.(hope this is the way to go)Was told by some to put fanfold on first and then housewrap, but most told me to put on housewrap first and then fanfold, so that is the way i went.My question is....Do i tape the seams or not? Thanks for any information! :)

Hello: Moved into a house that has T1-11 vertical siding. At the bottom, the siding is "finished off" with a horizontal board that runs the width of the house. Typical pine board, perhaps 6" X 3/4 x ... The bottom edges of some of the siding (rests on top of the 3/4 board edge) has wicked up water over the years, and looks as if I'll have to replace some of it. Also, a new horizontal board, as it does improve the looks. It has been suggested that I make sure to have the bottom edge of the siding where it meets the horizontal board be flashed with a "Z Flashing". Certainly sounds like a good idea. Found a picture of Z flashing on the web, and my question relates to the top most vertical edge of the flashing: Obviously there can't be a perfect seal here between the edge of the AL flashing and the face of the siding board. When it rains, due to small gaps between, or just capillary action, I would imagine water seeps in and probably migrates to the bottom siding edge (again). Is this anything to worry about ? Is the paint that goes over all of this supposed to seal it adequately, or should one run a small bead of RTV here, or... ? Any thoughts on all of this would be most appreciated. BTW: T1-11 still used and available ? Thanks, Bob (PS: Is this the most appropriate forum for this ?)
