Abstract
A building structure adapted to allow for ventilation of vapors from within the structure so as to retard deterioration of the structure. A sloped roof has a decking and a sheet overlying the decking. The sheet has a plurality of projects projecting upward away from the decking. The sloped roof has a vent slot disposed along a roof ridge adapted to permit air from an interior space under the roof to flow through the slot to the exterior. A strip has a surface shaped to match the projections of the sheet. The strip has an air permeable and resilient portion. A ridge cap overlies the slot and the strip. The air permeable and resilient portion of the strip is adapted for the flow of vapors.
Claims11
A building structure adapted to allow for ventilation of vapors from within the structure to an exterior area so as to retard deterioration of the structure, comprising:
- a sloped roof having a decking and a sheet overlying the decking;
- the sheet having a plurality of projections projecting upward away from the decking;
- the sloped roof having a vent slot disposed along a roof ridge adapted to permit air from an interior space under the roof to flow through the slot and to the exterior;
- a strip having a surface including a plurality of recesses shaped to match the projections of the sheet, the surface engaging the sheet, the strip having an air permeable and resilient portion;
- and
- a ridge cap overlying the slot and the strip, wherein the air permeable and resilient portion of the strip is adapted to allow the flow of vapors from within the structure to an exterior area.
A method of improving ventilation to a building comprising the following steps:
- providing a roof having a vent slot disposed along a roof ridge, the roof having a decking and a metal sheet overlying the decking, the metal sheet having a plurality of projections projecting upward away from the decking;
- providing a strip having an air-permeable and resilient portion, the strip having a surface having a shape including a plurality of projections and recesses to complement the projections of the metal sheet;
- aligning the recesses in the surface of the strip with the complementary projections of the metal sheet;
- installing the strip to the metal sheet so that the surface engages the metal sheet;
- and
- installing a ridge cap overlying the slot and the strip.
A method of installing a metal roof to a building comprising the following steps:
- installing a decking to the building;
- providing a vent slot disposed along a roof ridge;
- installing a plurality of metal panels, the panels each having a pair of lateral sides and a plurality of projections, on the decking such that the projections projecting upward away from the decking and one of the projections in proximity to the one of the lateral edges overlaps the projections on an adjoining panel in proximity to the other lateral edge;
- providing an air-permeable and resilient strip having a surface having a shape to compliment the projections of the metal panels;
- installing the strip overlying the metal panels in proximity to the vent slot;
- installing a ridge cap overlying the slot and the strip.
