Flexible high collar roof flashing |
摘要 |
A roof flashing for sealing an opening in a roof through which an upstanding pipe extends includes a base member having an opening for passage of the pipe and a collar attached to the base member surrounding the opening in the base member for receipt of the pipe when the base member is attached to the roof. The collar has corrugations which permit the collar to be expanded and compressed to different lengths to accommodate different length pipes within the collar. The corrugations at the outer end of the collar are flattened out to facilitate folding of the outer end over an upper end of the pipe to form a watertight seal between the collar and pipe.
