I am looking at replacing the facia, soffits and rain gutters on a 30 year old house. The facia and soffits are wood/plywood and starting to rot...probably due to weather and poor gutter installation. I am not sure what is better, aluminum or vinyl soffits and facia panels, or a combination??...The width of current soffits is 36" from facia board to outside wall. Also, is a wood facia board or something man-made better?? I figured seamless gutters are probably best but I really wanted to do it myself, or is there a seamless system I can do??
