This structural certification letter is designed for residential rooftop solar photovoltaic (PV) systems across North Carolina. It meets the statewide inspection requirements set by the NC Department of Insurance and Office of the State Fire Marshal for wind uplift, structural load review, and compliance with ASCE 7-16 and the NC Residential Code.

Whether you’re installing panels on shingle, metal, or tile roofs — or working in a 140 mph wind zone — we deliver a signed & sealed package to keep your project moving.

🧾 What’s Included:

✔️ PE-Sealed Wind Uplift Certification Letter (North Carolina Licensed)

✔️ Wind Pressure Calculations (ASCE 7-16)

✔️ Structural Review of Panel Mounting Layout

✔️ Anchorage & Load Distribution Review

✔️ Letter Format Acceptable to ALL NC Jurisdictions (per 2019 Uniform Solar Guidance)

☀️ Use Cases:

Shingle or Metal Roof Solar PV

💬 FAQs:

Do I need this for all NC solar permits?

No — but you MUST provide a PE-stamped structural design if any of the following apply:

• Your solar array weighs more than 3 psf

• The roof has >1 layer of shingles

• You’re mounting to tile or other non-shingle/metal material

• The job is located in a 140+ mph wind speed area.

Is this required statewide?

Yes. Since 2019, all local building departments in NC must follow the Statewide Uniform Inspection Requirements for rooftop solar

What’s the wind zone for my property?

We use the ASCE 7-16 wind maps and site ZIP code to determine the Vult design speed. Many NC coastal counties exceed 140 mph.

Can I use this for HOA or resale documentation?

Yes — our letter meets structural documentation needs for appraisals, closings, or homeowner association submittals.

Can this be bundled with electrical permit support?

We do not provide electrical plans — but we can coordinate with your electrician if needed and reference NEC compliance items.
