Hey everybody. I’ve posted a similar question before but hey I’m anal and paranoid about my house. I put Tar paper over the plywood a couple of months ago and now I’m putting the vinyl siding up. I’m putting 3/8 extruded polystyrene fan fold over the tar paper and the vinyl on top of that. I’ve kept the joints in the foam tight so I’m sure the amount of moisture that could possibly get past the siding AND the foam would be minimal. My question is how do you know if the tar paper is still effective. Obviously its been in the sun for a while so the face is faded. It really hasn’t curled much and the back side is still looking new (dark black). Is there a way to tell if its lost its effectiveness. I know people have already said it should be fine and I can go on with the siding and I trust that. It’s more out of curiousity how u tell if tar paper is still going to be effective. Thanks.
