Hi, I assume if these are safe for rubber roofs they are OK to put atop fiberglass roofdeck patios/roofs as well? Ie, whatever is on the bottom that touches the roof is soft and not hard plastic like it appears the actual tiles are?
We do not recommend using these tiles on rubber or fiberglass roofs since the bottom of these tiles is made of hard plastic. Please use our Soft Flex Tiles for this purpose.
