FRSA-TRI 6th Edition Tile Manual - April 2021

Thu, Apr 01, 2021

The High-Velocity Hurricane Zones (HVHZ) utilizes the roofing application standards (RAS) 118, 119, 120 and 127 for their requirements for roof tile installation.

With the adoption of ASCE 7-16 into the FBC, roof design pressures have changed and more calculations or information from the tile manual tables are needed to establish uplift moments and the potential need for stronger attachments. Other notable changes include:

■ Matrix revisions for underlayment and flashing
■ New project design flow charts
■ Design attachment system examples
■ ASCE 7-16 design roof zone reference
■ Updated tables for underlayment and ridge attachment per ASCE 7-16
■ Revised tables for required uplift of field tile per ASCE 7-16
■ Revised and improved installation detail drawings 

Matrix Revisions
The matrix is a table (next page) that was created to help contractors determine the type of roof that will be installed following a set method. The table flows from left to right. Each step is dependent upon the next and cannot be mixed. Select your roof system and follow the matrix each step of the way. Read More.
