We recently build a new house and I was poking around the attic today when I noticed some dark spots on the wood rafters. Do these look like mold?https://ift.tt/2HcUd3z picture of the vertical piece is not very clear since it was hard to access it up close but it looked very black and had what seemed like moisture beads scattered around in it. The other picture I could take from a spot up close, and if you touch the wood in the black spot it kind of flakes off in your hand.The builder said he'll doublecheck with his framer but he thinks it's just sap oozing from the knots in the wood. What do you guys think? via /r/DIY https://ift.tt/2Le9HqK
