Hello Wrenches, I have a job on a 3.5/12 pitched rubber roof. We have 1.5” foam under the EPDM, then the steel decking, then the purlins. Purlin spacing supports adequate attachment points for a conventional rail mounted system. I have 2 questions 1) A typical L-foot attachment to the roof would likely compress the underlying foam and result in divets at each foot. What do you recommend to disperse the load at the point of attachment 2) What type of screw do you recommend for attaching the L-Feet to the purlins
