 Glenn in Arkansas is on the line with a roofing question. What's going on at your money pit? Well, I have some moss on my roof. I had had a bunch of tree limbs there, then I got those cut. Just got a little bitty piece of the moss here and there growing on the west side of my roof. And I just want to know what I can do to maybe get rid of it and keep from coming back that won't hurt the roof. So, Willie, you took the first step by getting rid of some of those trees. You'll have more sunlight, and that will have a natural effect, sort of a natural mildew side effect.
