However in some situations we will get in to substainal roof repair and we will sub-out the roof work.\n\nSolarDave: Does a client come to you and say, \"Give me a new roof and a solar array\". (This is something that I need)\n\nTony Boniface:Yes, that is not tpyical but more typically when we get to a concrete tile roof then we will need a roofer to come in and cut the tiles so we can put the stand-offs on come back in, flash, reroof and then come in and finish the system. alternative, energy, panels, roofing, solar, solardave, tiles
