Hi PWR community,
Would soft washing a tile roof (cleaning with a 3-4% Sodium Hypochlorite roof mix) run the risk harming the underlayment?
My concern is the chemical will leach through to the underlayment onto the tile (unlike a typical asphalt shingle roof) and dry out the underlayment (tar paper).
Does anyone know of some good soft wash videos regarding concrete tile roofing?
I appreciate your help (in advance).
