Building Code 

Building Products

Note: Effective August 1, 2018, TDI will no longer maintain a list of asphalt shingle products that complies with the adopted standards for the Windstorm Program. The adopted code standards require shingle manufacturers to indicate compliance to either ASTM D 3161 or ASTM D 7158 standards on the shingle wrapper. All windstorm inspectors (Appointed Qualified Inspectors and TDI Field Inspectors) should be looking for these standards on the shingle packages as part of the inspection process. Since the code requires manufacturers to label their products, it is not necessary for TDI to maintain the asphalt shingle list.
