Enter an address and a few building details. Get the ASCE 7-22 design pressures in psf for components & cladding, MWFRS, and roofs — the design wind speed is looked up for you — then download a permit-ready Engineering Report.
Whatever surface you're designing, the pressure comes out in psf — cited, and permit-ready.
Most tools do one thing. This one returns the design pressure for the panel, the frame, and the roof from the same job address — no re-keying, no second app.
Enter a ZIP and the design wind speed is looked up — then the calculator applies exposure, topography, and the enforceable Florida Building Code value where it applies.
The output is a full Engineering Report, not a black-box number. Each coefficient cites its ASCE 7-22 section so a reviewer can follow the math line by line.
The math is ASCE 7-22; the workflow is plain language.
Type the ZIP or address. The mapped ASCE 7-22 design wind speed and the site exposure come back instantly.
Set the dimensions, roof shape, height, and enclosure. Pick the surface you're designing — wall, roof, or the whole frame.
The velocity pressure and design pressures come out in psf, by zone, with the Florida HVHZ value applied where it governs.
Export the Engineering Report as a PDF — every coefficient cited to its ASCE 7-22 section for the permit set.
Pick the surface; the calculator returns its design pressure.
Component & cladding pressures for wall panels, windows, and doors — interior (Zone 4) and corner (Zone 5), by effective wind area.
Gable, hip, monoslope, flat, and overhangs — with the corner and edge suction that governs panels, membranes, and fasteners. Open the roof uplift calculator →
Directional pressures on the windward, leeward, and side walls and the roof — the loads the structural frame is designed to.
Force coefficients for solid and open signs and freestanding walls, per ASCE 7-22 Chapter 29.
Equipment, chimneys, tanks, and trussed towers — the specialty pressures Chapter 29 covers.
Parapet and attached-canopy pressures plus rooftop and ground-mount PV wind loads.

No paid testimonials — a verifiable 24-year track record.
Yes. The wind speed lookup is free for any U.S. ZIP with no signup, and the free calculator returns a single component & cladding design pressure. Full projects, MWFRS, roofs, and the downloadable Engineering Report are on the paid calculators, with a free trial to start.
ASCE 7-22 — the current standard adopted by the Florida Building Code 8th Edition and most states. It is not a 7-16 tool; the coefficients, wind maps, and equations are 7-22.
Design pressures in psf for the surface you select — components & cladding by zone, MWFRS by wall and roof face, or roof uplift — plus the velocity pressure and every coefficient, packaged as a downloadable Engineering Report.
No. The software produces an Engineering Report, not a sealed document. A PE sign-and-seal is a separate professional service, available in all 50 states through our in-house Florida P.E. (residential up to three stories) and our PE network for everything else.
Yes. For the High-Velocity Hurricane Zone counties — Miami-Dade and Broward — it applies the enforceable Florida Building Code design wind speed and pressures automatically, so the value you submit is the one the jurisdiction checks against.
Yes. From one job address you can get component & cladding pressures, MWFRS directional pressures for the whole building, and roof pressures — along with signs, walls, equipment, parapets, canopies, and solar.
No. You provide the location and building details in plain language and the calculator applies the ASCE 7-22 procedure — exposure, Kz, Kzt, Kd, GCp, and internal pressure. Where a jurisdiction requires a stamp, PE seal service is available.
Enter a ZIP and building details and get the ASCE 7-22 design pressures in psf, with a downloadable Engineering Report. Start with the free calculator, or see every calculator and its pricing.
