A fungus among us...

This tile roof had a serious leak into the living room and the home owner never fixed it for many years. She said "It would only leak once in a while and never really became much of a bother." Over time the roof decking boards became soft with a fin layer of fungus or wood rot. A wire brush and some liquid fungicide (Copper-Green) got rid of it in preparation for the permanent surface patch. The board would have been super difficult to remove and replace. Thankfully, "ROOFING MASTIC & FIBERGLASS FABRIC, TO THE RESCUE." It won't leak here for a million years...
