The flange is arranged above the insulation for the roof. A hollow cap member has an open bottom and fits on and over an upper end portion of the sleeve member. A threaded connecting member extends downwardly from a horizontally extending section of the cap member and is located within the cap member. The support member has means for threadedly receiving the connecting member and for thereby detachably connecting the cap member to the support member.
