This picture is taken under the deck. (The bolt is where the deck is secured to the house.)
There is a gap between the siding (on the left) and the aluminium sheet (on the right.)
In the gap, looks like there is house wrap, and wood behind it. Today it rained, and the wood inside the gap is wet. Although I don't know exactly where the water comes from that caused the wetness... Directly from the gap, or somewhere else...
My question is: Should I seal the gap or cover it in anyway?
Thanks a lot.
