ABSTRACT:
An improved roof structure using flexible sheets of waterproof roofing material such as a felt backed polyvinyl chloride. An inverted generally V-shaped channel joins adjacent edges of the sheets of material. The channels have sides and an apex extending above the normal maximum water level on the roof structure during heavy rains. The adjacent edges of the material are bonded to the opposite sides of the channel and are further sealed by overlapping and bonding together or by a bonding to the inside of a second, overlapping inverted V-shaped channel. The air space in the first generally V-shaped channel may be vented to the atmosphere to prevent sweating beneath the roofing material.
