wind uplift pressure considerations

The ASCE sets standards used in building. These standards promote safety in building. Among many things, they tell us how to calculate wind uplift pressures. Most building codes rely on their advice.

Pounds Per Square Foot, Not Actual Wind Speeds

Roofing Contractor points out that ratings for roofing systems consider pressures in pounds per square foot. That article offers details about wind uplift ratings from one rater.

Anyway, many people assume that it means wind speed itself. Actually, rating needs consider multiple factors. Really, there’s no way to determine a rating needed using basic wind speed only. That’s just one factor out of the five basic factors usually considered.

Uplift Calculations for Roofing Systems

State or local rules usually say what calculation to use. Civil engineers determine the needs of an individual roof. They consider five basic factors:

  • building height
  • building location
  • surrounding terrain
  • building openings
  • building use

Then, they plug the data into a formula. That shows pressure in pounds per square foot that the building may face. Then, builders know what rating they may need.
