A roofing installation comprising a plurality of basic supporting elements for blocks of insulation upon which is disposed a composite board. A plurality of spot bonding pads and the composite board are covered respectively with a flexible membrane cover and with a roofing membrane which is flexible and preferably formed of rubber. The cover extends over each spot bonding pad and is adhesively secured thereto, the cover extending beyond the edges of the spot bonding pad and such extensions of the cover are adhesively secured to the flexible membrane. Each spot bonding pad is adhesively secured to the flexible membrane. A screw extends through the cover, the spot bonding pad, the membrane, the composite board, the insulation and the remaining roofing elements. Means covering the head of the screw is adhesively secured thereto and to the aforesaid cover and, in this form of the invention, the cover is not adhesively secured to the spot bonding pad and the spot bonding pad is not adhesively secured to the flexible membrane. An additional form of the invention encloses the head of the screw by the cover which is adhesively secured to the flexible membrane as well as the head of the screw, the spot bonding pad and the flexible membrane.
