Abstract
A fungi resistant asphalt is combined with a base sheet to form a fungi resistant asphalt containing sheet material. Typically, the base sheet is a fibrous base sheet that, by itself, may or may not be fungi resistant. The fungi resistant asphalt is at least partially absorbed by the base sheet to form the fungi resistant asphalt containing sheet material and typically forms one or both major surfaces of the fungi resistant asphalt containing sheet material.
