Abstract
A one piece flexible elastomer boot membrane flashing of EPDM extends from the roof upwardly around the wood base frame and over the top edge to provide a complete seal for a skylight window unit. A tape seals the outer edges of the outwardly extending peripheral lower flange portion of the boot to the roof. The skylight may be either of the fixed or ventilator type.
