📦 Austin Rooftop Equipment Wind Certification
✅ Structural Wind Load Letter for HVAC, Generators, Solar Batteries, Mini-Splits & More
This engineer-sealed letter is designed for roof-mounted mechanical or electrical equipment in the City of Austin. It verifies that the rooftop unit is properly secured against wind uplift and lateral loads, per ASCE 7-16 and the 2021 IBC adopted by Austin.
Whether you’re installing a new HVAC system, backup battery, or generator — or replacing one — many plan reviewers now require wind anchorage documentation for permitting.
🧾 What’s Included:
✔️ PE-Sealed Wind Load Certification Letter (Texas Licensed)
✔️ Uplift & Overturning Calculations (based on equipment weight & dimensions)
✔️ Roof Curb, Platform, or Bracket Anchorage Check
✔️ Wind Pressure Determination (Vult = 140 mph, Exposure C)
✔️ PDF Letter Ready for Permit Upload
🔌 Use Cases:
Rooftop HVAC Unit (RTU)
Mini-Split Condenser on Roof or Platform Solar Battery Storage
Cabinet Backup Generator (Residential or Commercial)
Fan Coil or Air Handler Units

💬 FAQs:
Do I need engineering if I’m replacing rooftop equipment?
Yes — most replacements still require anchorage verification if the equipment size or weight changes.
What if I don’t have full curb or bracket specs?
We’ll work with your contractor or installer to assume standard curb height, anchorage spacing, and unit weight.
Is this letter accepted by the City of Austin?
Yes — it’s formatted to meet their 2021 IBC + ASCE 7-16 adoption. We also add specific site assumptions.
Can this include multiple units?
Yes — just let us know quantity and layout. We can issue combined packages for multiple roof-mounted units.
