Abstract
A single sheet of relatively stiff material is formed with a flat rim surrounding a raised area except along one open side or edge with the raised area having a low elevation so as to present a low profile when placed on the roof and is in air communication with an opening through the roof with the open edge providing an opening for air passage to the atmosphere and having a baffle at the open edge to prevent foreign materials and rain from entering and having tabs at the open edge for grasping the edge of a covering roof shingle. Preferably the vent is triangular in top plan so that the apex angle of the vent opposite the open edge can be easily inserted under a shingle between the nails which hold the shingle in place.
Claims3
For a slanted shingled roof having a ventilating opening, a low profile ventilator, comprising:
- a single sheet of generally triangular substantially stiff material formed into a raised area defining a low profile chamber which is open at one edge only and closed along the other edges by low side walls with a flat rim extending around the bottom edges of said side walls, said rim resting against the roof so that said chamber is above and in air communication with the roof ventilating opening and slanted downward along the roof toward said open edge from the ventilating opening;
- said raised area being uncurved so that the covering shingle lays flat on top of the raised area;
- a foraminous screen closing off the open edge of said chamber;
- and
- tabs at said open edge for engaging the edge of a roof shingle covering over the ventilator for holding the shingle in place on top of the ventilator.
