Abstract
Abstract A roof construction employs a continuous corrugated baffle between adjacent parallel spaced roof members which is secured between the roof deck and the roof members. The baffle may extend from the facia to the ridge or any intermediate area therebetween and provides at least one channel between adjacent roof members for conducting air from the facia to a vent at the ridge to prevent the formation of ice dams on the roof in the winter as well as providing an interior flashing for collecting and removing water which incidentally seeps through the roof deck. A second embodiment employs a continuous sheet as a baffle while a third embodiment employs a continuous sheet having spacing fins for forming the channels.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
153 words
In a dwelling, a vertical exterior wall, a series of generally parallel spaced roof members supported on the wall, a roof deck supported by said roof members, baffle means including a member having first and second portions confined between the upper edges of adjacent roof members and the roof deck and third portions located between said adjacent roof members and spaced from said roof deck to define at least one channel therebetween for conducting ventilating vapor beneath the roof deck and removing liquid which has leaked through the roof deck, air inlet means located outwardly of the vertical wall and communicating with the outer end of said channel, and air outlet means located inwardly of said vertical wall and communicating with the inner end of said channel, whereby air will enter said air inlet means and flow through said channel in contact with the undersurface of said roof deck to said outlet means.
Claim 2
Dependent Claim
153 words
In a dwelling, a vertical exterior wall, a series of generally parallel spaced roof members supported on the wall, a roof deck supported by said roof members, baffle means including a member having first and second portions confined between the upper edges of adjacent roof members and the roof deck and third portions located between said adjacent roof members and spaced from said roof deck to define at least one channel therebetween for conducting ventilating vapor beneath the roof deck and removing liquid which has leaked through the roof deck, air inlet means located outwardly of the vertical wall and communicating with the outer end of said channel, and air outlet means located inwardly of said vertical wall and communicating with the inner end of said channel, whereby air will enter said air inlet means and flow through said channel in contact with the undersurface of said roof deck to said outlet means.
Claim 3
Dependent Claim
47 words
The dwelling of claim 1, wherein said baffle means includes a continuous corrugated strip having a plurality of alternately spaced ridges and grooves with certain of said ridges adapted to grip the upper portion of said spaced roof members and said grooves defining a plurality of channels.
Claim 4
Dependent Claim
29 words
The dwelling of claim 2, wherein said ridges between adjacent roof members define spacing means adapted to maintain said grooves in spaced relationship with respect to said roof deck.
Claim 5
Dependent Claim
32 words
The dwelling of claim 1, wherein said baffle means includes spacing means engageable with the undersurface of the roof deck for maintaining said third portion in spaced relationship to said roof deck.
Claim 6
Dependent Claim
35 words
The dwelling of claim 4, wherein said spacing means includes at least one projection connected to said baffle means and disposed to collapse when sandwiched between one of said roof members and said roof deck.
Claim 7
