An extruded foam polystyrene sheet is formed into a roof vent panel for a sloping roof at the eaves. The panel has flanges and an offset wall and is formed into through troughs end-to-end which are divided by truncated triangular ridges extending from the offset wall. The ridge is reinforced by gussets and saddles which are formed as sets along the ridges. The gussets extend from the offset wall to the ridge side walls and the saddles connect the ridge side walls below the truncated apex of the ridge. The gussets on each side wall are spaced and paired with one of each pair at the end of a saddle.

A structure sloping roof vent panel comprising a large elongated panel of extruded foam polystyrene sheet having lateral flanges to facilitate the fastening of the sheet to the underside of a sloping roof at the eaves, an offset wall spaced from said flanges forming an airway trough, and at least one generally triangular ridge extending from said offset wall and open from one end of the vent panel to the other, said ridge having thinner side walls than said offset wall, and formed gussets extending from said offset wall to said thinner side walls of said ridge to reinforce and strengthen said panel sheet to maintain unobstructed venting through said trough when installed.
