I was out inspecting my roof today and found one corner that wasn't finished well. I took a pic: I'm tempted to squirt some black roof repair caulk into the hole under the shingles. The wood beam that is sticking out might be construction or it might be decorative. I'm not sure right now. I thought about sanding it and painting it, but the area is so small and not visible that I would consider something less attractive if it's simpler/quicker. Any advice for me?
