Calculator


The 2015 IRC references two tables to determine the required design wind uplift pressures for roof coverings. Using these tables can be confusing, so FORTIFIED created a calculator to help roofers and evaluators determine the appropriate design pressures for steep-slope roof coverings.

Technical Bulletins
