The roof at DataDoc had considerable gravel build up, so Seamless Roofing Inc. first had to remove all loose gravel. This was followed by cleaning all dirt and gravel that remained on the roof. We then applied a specially formulated emulsion adhesive over the top of the gravel. This adhesive flood coats the roof surface encapsulating the gravel, allowing the roofing fabric to adhere to the gravel. This was followed by a white silicone top coat.
