Windstorm Inspection Checklist: How to Prepare Your Property
Windstorm Inspection Checklist: How to Prepare Your Property
A windstorm inspection is a critical step in obtaining your WPI-8 or WPI-8E certification. Failing the inspection means delays, additional costs for re-inspection, and potential construction rework.
Use this checklist to make sure your property is ready and your inspection goes smoothly on the first try.
Before the Inspection: General Preparation
☐ Schedule at the Right Time
For WPI-8 (ongoing construction), timing is critical. The inspection must happen when structural elements are still visible:
- Re-roofing: Schedule after roof deck is installed but before underlayment and shingles go on
- New construction: Schedule after framing and roof deck, before sheathing covers connections
- Additions: Schedule when structural connections are exposed
For WPI-8E (completed construction), schedule at any time — the engineer will inspect what's accessible.
☐ Clear Access to All Areas
Ensure the engineer can access:
- Roof — clear path, safe ladder access, no debris
- Attic — clear path to inspect roof framing and connections
- Exterior — all sides accessible, no overgrown vegetation
- Interior — access to areas where structural connections may be visible
- Crawlspace/basement — if applicable, clear access
☐ Gather Documentation (WPI-8E Only)
If your construction is already complete, gather:
- Building permits and approved plans
- Contractor records and invoices
- Material receipts (roofing, fasteners, connectors)
- Previous inspection reports (if any)
- Manufacturer specifications for installed materials
- Photos taken during construction (if available)
Inspection Day Checklist
Roof Inspection Preparation
- ☐ Roof deck installed and visible (for WPI-8)
- ☐ Roof deck properly fastened (correct nailing pattern)
- ☐ Roof trusses/rafters installed and connected
- ☐ Hurricane straps or clips visible and accessible
- ☐ Roof-to-wall connections accessible for inspection
- ☐ No debris or materials blocking inspection areas
- ☐ Safe ladder access to roof (or arrange with contractor)
Structural Connection Preparation
- ☐ Wall-to-foundation connections visible
- ☐ Floor-to-wall connections accessible
- ☐ Roof-to-wall connections exposed (most critical)
- ☐ Hurricane straps/clips properly installed
- ☐ Hold-down anchors visible (if applicable)
- ☐ No structural elements concealed before inspection
Opening Protection (Windows & Doors)
- ☐ Impact-rated windows installed (if required by code)
- ☐ Impact-rated doors installed (if required)
- ☐ Storm shutters installed (if used for protection)
- ☐ All openings meet wind-borne debris requirements
- ☐ Manufacturer labels visible for verification
Attic Access
- ☐ Attic access clear and safe
- ☐ Roof framing visible from attic
- ☐ Truss/rafter connections to wall plate visible
- ☐ Roof deck underside accessible for fastener inspection
- ☐ Adequate lighting or provide flashlight
Documentation Ready
- ☐ Building permit on site
- ☐ Approved construction plans available
- ☐ Contractor or builder present (recommended)
- ☐ Material specifications/receipts available
- ☐ Previous inspection reports (if applicable)
Common Reasons Inspections Fail
Don't let these issues catch you off guard:
1. Concealed Structural Elements
Problem: The most common failure cause. Drywall, siding, or roofing installed before inspection, hiding structural connections.
Solution: Schedule the inspection before finishes are applied. Coordinate with your contractor.
2. Incorrect Fastener Patterns
Problem: Roof deck nails spaced too far apart or missing nails in high-wind zones.
Solution: Verify nailing pattern matches code requirements (typically 6" on center at edges, 6"/12" in field for high-wind zones).
3. Missing Hurricane Straps
Problem: Roof-to-wall connections lack proper wind-resistant connectors.
Solution: Install approved hurricane straps or clips at every rafter/truss-to-wall connection.
4. Non-Compliant Opening Protection
Problem: Windows and doors don't meet impact resistance requirements for wind-borne debris regions.
Solution: Install impact-rated products or approved storm protection systems.
5. Incomplete Documentation (WPI-8E)
Problem: Missing permits, plans, or material records make retroactive certification impossible.
Solution: Gather all available documentation before the inspection. Contact your contractor for records.
Tips for a Smooth Inspection
- Have your contractor present — they can answer technical questions and address issues immediately
- Keep all structural elements exposed until the inspection is complete
- Have your permit and plans on site for the engineer to review
- Ask questions — our engineers are happy to explain what they're checking and why
- Don't rush — a thorough inspection takes 30-60 minutes depending on project complexity
What Happens After the Inspection?
If Your Project Passes
Congratulations! Our engineer will:
- Prepare all TDI certification documents
- Submit paperwork to the Texas Department of Insurance
- Provide you with digital copies of all documentation
- Your certification is typically processed within 5-14 days depending on service level
If Issues Are Found
Don't panic. We'll provide:
- A detailed report of all issues identified
- Specific recommendations for corrections
- Guidance on what needs to be fixed before re-inspection
- A re-inspection once corrections are made
Our goal is to help you achieve compliance — not to fail your project. We'll work with you and your contractor to get your property certified.

Frequently Asked Questions
How long does the inspection take?
Most inspections take 30-60 minutes depending on project size and complexity. Larger commercial properties may take longer.
Do I need to be present for the inspection?
It's recommended that you or your contractor be present. The engineer may need access to interior spaces and may have questions about the construction.
What if it rains on inspection day?
Light rain is usually fine for interior/attic inspections. Heavy rain may require rescheduling for roof inspections. We'll contact you if weather requires a change.
Can the inspection be done without my contractor present?
Yes, but having your contractor present is highly recommended. They can answer technical questions about materials and installation methods, and address any issues immediately.
