🪵 Boulder Pergola & Deck Wind Certification
✅ Structural Letter for Open Structures (Permit-Ready for Boulder City & County)
This wind certification package is designed for open or partially enclosed structures such as pergolas, patio covers, decks, or trellises. Whether attached or detached, any structure over 30 inches tall in Boulder typically requires permit submittal — and in most cases, wind load engineering.
This Colorado PE-stamped letter verifies structural stability against Boulder’s elevated wind pressures, including uplift and overturning calculations for foundations.
🧾 What’s Included:
✔️ PE-Stamped Wind Load Letter (Colorado Licensed)
✔️ Site-Specific Wind Pressures (Vult 150–165 mph or SEAC Interpolation)
✔️ Foundation Uplift & Overturning Calcs
✔️ Exposure Category + Kzt (if applicable)
✔️ PDF File – Ready for Permit Upload

Attached Patio Roof Additions Trellis, Gazebo, or Open Pavilion Structures
Detached Accessory Roofed Elements

💬 FAQs:
Do I need an engineering letter for my pergola in Boulder?
Yes — if the pergola is roofed or exceeds permit thresholds, plan reviewers will require wind and foundation calculations.
What if it’s a detached freestanding structure?
Still likely needed — Boulder permits most structures over 120 sf or 30" tall. Even freestanding pavilions must prove stability in high winds.
What if I don’t have exact footing dimensions?
We’ll provide a compliant engineered footing layout based on wind pressures and span — contractor may adapt to site conditions.
Do you stamp for Boulder?
Yes — all documents are signed and sealed by a licensed Colorado PE and formatted for both city and unincorporated county use.
