COPYRIGHT© FRSA/FILE ROOFING INSTITUTE April 2012 HIP AND RIDGE INSTALLATibN General - The following recommendations are only for products approved by the Florida Building Code (FBC) and tested according to SSTD-I I via third party independent FBC approved laboratories. Theyrvill determine the wind upllift limitations of the various hip and ridge attachment methods or by installation methods currently recognized in the High Velocity Hurricane Zone (HVHZ) section of the FBC. There are three basic attachment methods of the hip and ridge tiles: mechani- cal attachment, adhesive -set and mortar -set attachment systems. The minimum head lap when installing hip and ridge tiles is 2" unless restricted by product design. Any exposed fasteners should be covered with a W resistant sealant Field Tile Cuts at Hip or Ridge - All cut field tiles adjacent to a hip pr ridge shall be attached to the Cap Sheet and/or the adjacent tile with an approved adhesive, mortar or mechanical fasteners and adhesive. The following table outlines the different parameters for the hip qnd ridge attachment options. See Drawing FHW-13. I I . ME Foam Metal Mechanical FOB Foam Coating Mortar Mortar Mechanical or Foam Mortar Plastic Foam Foam Foam Coating Mortar Mortar Foam Foam Coating Mortar Mortar Foam Mechanical I Foam Coating Wood H-Bracket Straps with , Flexible Dry Adhesive Mortar Mortar Foam Mortar Mortar Mortar Mortar Mortar Mortar Hip and Ridge Attachment - Choose one of the following. • Metal Member - Set member in plastic cement or compatible sealant Fasten 6" on center on each side of the metal flange with minimum 1-1/4" ring shank roofing nails. If mechanical attachment of the member is not used, install the member with Foam per the manufacturer's instructions. ment, Mortar can be used as a structural attachment Place a full bed of pre -bagged mortar under the entire tile. Each tile must be fully embedded into the mortar. The field tile secured to the underlayment along with the mortar on each trim tile creates the structural bond. The entire cavity under the trim tile should be filled with approved mortar. Starter Tiles -All startertiles must besecured at both ends Plastic Member -'Install the member with Foam per of the tile either with mechanical fasteners, mortar and/or the manufacturer's instructions. adhesive. Wood Member - Fasten 18" on center with four #8 screws per metal strap or H-bracket. Each attachment point shall have two fasteners on each side of the wood member. The fasteners shall be spaced evenly on the metal strap or H-Bracket with the attachment holes parallel to the hip or ridge. The Straps and H-Brackets shall be a minimum of 26 gauge. A11 materials must be compatible with each other. If mechanical attachment of the wood member is not used, install the member with Foam per the manufacturers instructions. Mortar - When using Foam or Mortar field tile attach - When the field tile is installed with foam or mortar, the starter tile may be installed with an approved mortar. If using a structural member choose one of the following. Metal Member - Place foam under starter tile per manufacturers recommendations or secure the head of the tile with one #8 screw and apply adhesive in the gap between the uctural support and the tile. The member may need to lye cantilevered to provide a base for the adhesive. The starter tile must make contact with the adhesive. See manufacturer's recommendations.
