Have some guys putting up a patio roof against the house and they are putting back the siding. I did have felt paper where the joints of the cement boards come come together but now the guys are using the aluminium instead. Will thiis be an issue or am I not remebering it right.? Read where the new P.T lumber doesn't like the Aluminum but how about the siding?? thanks Walt
