ricbob Report post Posted March 16, 2017 I got a call from a guy here in palm harbor. He had a huge rubber tree cut, it was hanging over the roof. The rubber sap, ran on the roof and the saw dust landed on that. It is embedded in the rubber , I need something that will dissolve the rubber, without hurting the shingles. nothing seems to touch it,,,,,any ideas???
