I will be installing solar soon on my epdm rubber roof. I am not concerned about leaks. Already I have installed a ladder and utilize Dicor Lap Sealant. Works perfectly. I will be doing the same. I am going to attached the mounts to the panels first and apply sealant to the bottom of mount then place the panel on the roof. Now fasten with a screw gun through the hole oozing in sealant. After apply more sealant over the top. This way sealant is under the bracket and also follows the screw into the hole. The Dicor self levels and makes for a nice neat waterproof install.
