An improved method of sealing and attaching, in a weathertight manner, a mounting support, such as a mounting support of an equipment, to a roof surface. A flared hole is formed in a sheet of metal flashing. The flashing is placed on the roof with the flared hole thereof aligned with a hole in the roof and protruding upward from the roof. A resilient pad is applied to the roof flashing over the flared hole, with a hole in the pad surrounding the flared hole in the roof flashing. The mounting support is then bolted to the roof surface by passing a bolt through the mounting support, the pad, and the aligned holes. The bolt engages the mounting support and the underside of the roof surface so as to secure the mounting support to the roof surface with the flashing and resilient pad pressed therebetween. This sealing technique provides a reliable water-tight seal through which water cannot readily penetrate, even over long periods of time.
