Two buildings that look the same can be built very differently depending on where they stand. The difference is the design load.
Wind load
Measured in miles per hour, it's the wind speed the building is designed to resist. Coastal and open areas need higher ratings. Higher ratings usually mean closer frame spacing, more bracing and more anchors.
Snow load
Measured in pounds per square foot (psf), it's the weight of snow the roof is designed to carry. Northern and mountain areas need more. A vertical roof sheds snow better than a regular roof.
Why we ask for your ZIP code
Local codes set the minimum wind and snow loads for your area. Your ZIP code lets us quote a frame that meets them from the start, instead of changing it later.
Certified drawings
Many counties require stamped engineering drawings for a building permit. Ask for certified drawings in your quote request and we'll include them in the proposal.
