Professional ASCE 7-22 wind load analysis with nothing to download or install. Open a tab, enter your project, and get instant design pressures for components & cladding, MWFRS, and roofs — across all 50 states.
No installer. No version you have to keep current. No license tied to one machine. Just professional ASCE 7-22 calculations on demand.
Traditional engineering software means installers, license servers, and annual upgrade cycles. WindLoadCalc skips all of it. Sign in and your projects are right where you left them.
Enter the location and geometry and the software returns zone-by-zone design pressures right away. The correct design wind speed is pulled from the project address automatically.
The software produces a clean Engineering Report with the inputs, the cited coefficients, and the resulting pressures. When a project needs a stamp, PE sign-and-seal is available separately.

No paid testimonials — just a verifiable 24-year track record.
No. WindLoadCalc runs entirely in your web browser. There is nothing to download, install, license, or update.
Open a tab on any computer, sign in, and start calculating design pressures.
The software is built on ASCE 7-22, the current edition of the standard. We have navigated 7 ASCE 7 editions since 2002.
Your calculations always reflect the standard building departments expect today.
It covers components and cladding for windows, doors, and shutters today. Main wind force resisting system (MWFRS) and roof pressure calculators are rolling out by category.
Each calculator outputs zone-by-zone design pressures.
Yes. The software supports projects in all 50 states and U.S. territories using ASCE 7-22 provisions.
Florida projects include High-Velocity Hurricane Zone (HVHZ) handling for Miami-Dade and Broward counties.
Yes. Florida projects apply the High-Velocity Hurricane Zone rules and Florida Building Code jurisdictional overrides where they apply.
The correct design wind speed is selected automatically from the project location.
You get instant zone-by-zone design pressures on screen, plus a permit-ready Engineering Report you can export.
Every coefficient traces back to its ASCE 7-22 section, so the math is never a black box.
Yes. PE sign-and-seal is available in all 50 states through the firm's professional engineer network.
The software produces the calculations; sign-and-seal is a separate service you can add when a project needs a stamped deliverable.
Our reports carry a 100% permit approval record across 24 years of operation. Every coefficient cites its ASCE 7-22 reference.
An in-house Florida P.E. stands behind the methodology.
Yes. A free tool lets you look up the design wind speed for any U.S. ZIP code with no signup.
From there you can start a free trial of the full calculators to run a real project.
Pricing is by calculator category as a simple subscription. See the current plans on the pricing page rather than guessing.
Totals are shown as a single price with no per-report fees.
No installer, no license server, no version to chase. Start a free trial of the ASCE 7-22 software, or run our free wind speed lookup first to check a ZIP's design wind speed.
Our free wind speed lookup handles every U.S. ZIP and applies Florida Building Code overrides for Miami-Dade, Broward, and Collier counties. No signup. No meter.
