Today the majority of roofs that we do are non-ballasted. For many roofs, however, removing the roofing stone presents new challenges. The dual role of this stone was to also protect the roof, not only from the elements but in many formulations from FIRE. Many roofing membranes are combustible (EPDM included) without the stone. Also the addition of stone helps to modify the extreme temperature swings (especially in black membranes).
