Abstract
A ridge vent system includes a screen layer positioned between an underlayment layer and a ridge vent cap. The screen layer includes a screen material positioned between sections of a second material and aligned over the ridge to enable air flow. The screen material is aligned over an underlayment slot and has a first side edge and a second side edge, the second material has a first section attached to the first side edge and a second section attached to the second side edge. The screen material may be heat welded to the second material. A layer of shingles may be positioned underneath the ridge vent cap, with the layer of shingles positioned to enable air flow through the ridge vent and vent cap. The screen material may further be coated with a durable coating such as a durable water repellent.
Claims20
A ridge vent screen system comprising:
- roof sheathing forming a ridge, and a slot defined in the ridge to form a ridge vent in the roof sheathing to enable air to flow through the ridge vent;
- an underlayment layer positioned on the roof sheathing, the underlayment layer defining an underlayment slot in the underlayment layer, the underlayment slot having a first side and a second side, the underlayment layer slot at least partially aligned over the ridge vent in the roof sheathing;
- a treated screen layer positioned on the underlayment layer, the treated screen layer including screen material and a second material, the screen material aligned at least partially over the underlayment slot and having a first side edge and a second side edge, the second material having a first section and a second section, the first section attached to the first side edge of the screen material and extending over the underlayment on one side of the underlayment slot, the second section attached to the second side edge and extending over the underlayment on the other side of the underlayment slot, wherein at least a portion of the screen material is treated with a durability coating, the at least a portion of the screen material aligned over the underlayment slot;
- and
- a vent cap at least partially aligned over the mesh material of the screen layer.
A ridge vent screen system comprising:
- roof sheathing forming a ridge, and a slot defined in the ridge to form a ridge vent in the roof sheathing to enable air to flow through the ridge vent;
- an underlayment layer positioned on the roof sheathing, the underlayment layer defining an underlayment slot in the underlayment layer, the underlayment slot having a first side and a second side, the underlayment layer slot at least partially aligned over the ridge vent in the roof sheathing;
- a screen layer positioned on the underlayment layer, the screen layer including screen material and a second material, the screen material formed from a porous mesh aligned at least partially over the underlayment slot and having a first side edge and a second side edge, the second material having a first section and a second section, the first section attached to the first side edge of the screen material and extending over the underlayment on one side of the underlayment slot, the second section attached to the second side edge and extending over the underlayment on the other side of the underlayment slot, wherein the screen material and the second material are each formed from a thermoplastic, and wherein the screen material is coated with a durable water repellent;
- and
- a vent cap at least partially aligned over the mesh material of the screen layer.
A method for installing a ridge vent screen system comprising the steps of:
- providing a roof support structure having a ridge;
- attaching a sheathing layer over the roof support structure;
- forming a sheathing slot in the sheathing layer, the sheathing slot aligned with the ridge;
- placing an underlayment layer over the sheathing layer
- forming an underlayment slot in the underlayment layer, the underlayment slot in alignment with the sheathing slot;
- providing a screen layer having a porous screen material attached to a non-porous second material;
- coating at least a portion of the porous screen material with a durable coating that maintains the porosity of the material;
- positioning the screen layer over the underlayment layer with the coated portion of the porous screen material in alignment with the underlayment slot;
- and
- attaching a ridge vent cap over the mesh screen layer.
