We Look Up Your Design Wind Speed
We geocode your address and read the ASCE 7 design wind speed (Vult) mapped for your county/state, plus whether you’re in a wind-borne debris region or Florida’s statutory High-Velocity Hurricane Zone.

Why your wind zone matters
Your design wind speed — the ASCE 7 wind hazard value (often written Vult, the “ultimate” design wind speed) mapped for your area — is what building codes use to decide how strong a roof, its connections, and its openings have to be. It also tracks closely with what you pay for wind and hurricane coverage. On its own it’s an engineering input; what makes it useful to a homeowner is knowing which threshold you fall into. Two things escalate the rules: being in a wind-borne debris region (where flying debris in a windstorm is likely, so openings must be impact-rated or shuttered), and being in Florida’s High-Velocity Hurricane Zone (HVHZ) — Miami-Dade and Broward counties, where the strictest product-approval and debris rules in the country apply by statute. This tool reads the design wind speed mapped for your county/state free, then explains what your threshold means for your roof and insurance — no phone calls and no signup.
How homeowners use their wind zone
Understand roof requirements: a higher design wind speed means stronger roof-to-wall connections, fasteners, and rated roof coverings
Know your opening rules: in a wind-borne debris region, impact-rated windows/doors or shutters are typically required
Anticipate insurance: higher wind zones and HVHZ status drive separate wind/hurricane deductibles and premiums
See your full picture: pair your wind zone with flood, storm, roof, and radon risk for the whole property
What the design wind speed is (and isn’t)
- Design wind speed (Vult): the ASCE 7 mapped wind hazard used by building codes for your area, in mph — an engineering input, not a forecast of the fastest wind you’ll ever see.
- A county/state indicator, not a point value: what we surface is derived from ASCE 7 wind maps at the county/state level. It is not a point-exact engineered value for your exact lot.
- Wind-borne debris region: a mapped area near the coast where debris is likely in a windstorm, triggering impact-rated or shuttered openings — flagged in the teaser and report where it applies.
- HVHZ is the one statutory exception: in Miami-Dade and Broward, Florida law sets the zone directly — there the designation is fixed by statute, not estimated.
- Not an engineered design: the permitted design wind speed for your specific structure is set by a licensed engineer or your local building department, not by this lookup.
A note on accuracy
This is a free, honest indicator, not an engineered figure. The design wind speed and grade we show are derived from ASCE 7 wind hazard maps at the county/state level — a confident starting point for understanding your area, not a point-exact value for your exact address. The one exception is Florida’s High-Velocity Hurricane Zone (Miami-Dade and Broward), which is set directly by statute. The actual design wind speed used for a permit is determined by a licensed engineer or your local building department — never treat the value here as surveyed or code-final. We surface the grade label honestly so you can see whether the number is a state/county baseline or a statutory HVHZ designation. Design wind speed based on ASCE 7 wind hazard maps.
Design wind speed based on ASCE 7 wind hazard maps. The full report also uses the Federal Emergency Management Agency’s OpenFEMA API for flood-zone context, but is not endorsed by FEMA. The Federal Government or FEMA cannot vouch for the data or analyses derived from these data after the data have been retrieved from the Agency’s website(s).
Frequently asked questions
How do I find the wind zone for my address?
Enter your address above. We geocode it and read the ASCE 7 design wind speed (Vult) mapped for your county/state, plus whether you’re in a wind-borne debris region or Florida’s HVHZ. The result appears free in seconds. It’s a county/state indicator, not a point-exact engineered value; the full report adds what it means for your roof and insurance.
What is the design wind speed (Vult)?
It’s the ultimate design wind speed from the ASCE 7 wind hazard maps, in mph — the value building codes use to decide how strong a roof, its connections, and its openings must be. It is an engineering design input, not a forecast of the fastest gust you’ll ever experience.
How accurate is this wind zone lookup?
The design wind speed and grade we show are derived from ASCE 7 wind maps at the county/state level — a solid indicator of your area, not a point-exact engineered value for your exact lot. The one exception is Florida’s HVHZ (Miami-Dade and Broward), which is set by statute. The design wind speed used on a permit is determined by a licensed engineer or your local building department.
What is the High-Velocity Hurricane Zone (HVHZ)?
The HVHZ is Miami-Dade and Broward counties in Florida, where state law imposes the strictest wind-borne-debris and product-approval requirements in the country. Unlike the mapped wind-speed indicator elsewhere, HVHZ status is set directly by statute, so where it applies we flag it as a statutory designation.
What is a wind-borne debris region?
It’s a mapped coastal area (generally where design wind speeds are high) in which flying debris is likely during a windstorm. In these regions, building codes typically require impact-rated windows and doors or approved shutters to protect openings. The teaser and report flag whether your address falls in one.
How does my wind zone affect my roof and insurance?
A higher design wind speed means codes require stronger roof-to-wall connections, more fasteners, and rated coverings; debris regions add impact-rated openings. On the insurance side, higher wind zones and HVHZ status commonly carry separate wind or hurricane deductibles and higher premiums. The full report explains what your specific threshold means.
Is this really free?
Yes. The design-wind-speed lookup is completely free — no credit card and no hidden fees. Enter your email to also get your full property risk report (wind zone, flood zone, storm, roof, and radon) at no cost; a deeper paid report is offered but never required.
