Aluminum Ridge Vent w/Nails

Aluminum ridge vents are installed across the crown of the roof to allow ventilation. Although the vent manufactures allow these vents to be installed with aluminum nails, the nails they provide are not long enough to penetrate the decking as required by the Florida Building Code. Most roofers will simply use the same nails as they use for installing shingles. However, these nails are galvanized and the vents are aluminum, fair and unfair metals, which lead to electrolysis. We suggest these nails be sealed and screws with special EPDM gaskets at the screw’s head be installed to prevent vent blow-off, self seal the fasteners and prevent further electrolysis.
