Pool and Screen Enclosure Engineer Letters in Florida

Screen enclosures and pool cages have their own chapter in the Florida Building Code for good reason: they are lightweight, heavily loaded under wind, and ubiquitous across the state. When one is built, replaced, or repaired — especially after a storm — the inspector’s job is to verify that the aluminum framing, connections, and anchorage resist the design wind pressure for the site.

When that inspection is missed, or when post-storm repairs go in before the permit is formalized, an engineer letter gets the file closed.

What the letter covers

A Florida screen enclosure engineer letter addresses the FBC Chapter 20 provisions for aluminum structures, referencing the Aluminum Association Design Manual and site-specific wind pressures calculated per ASCE 7-22 (or the edition in effect at permit issuance). Specifically:

• Member sizing. The primary beams, knee braces, columns, and rafters are sized for the design load combinations including the wind pressures at the structure’s height, exposure, and enclosure classification.
• Connection capacity. Self-drilling screws, TEK fasteners, and mechanical connections are verified against the Aluminum Design Manual and manufacturer test data.
• Anchorage to concrete or slab. The expansion anchors, epoxy anchors, or embedded connections are sized for the uplift and shear at each base plate, with proper edge distance and embedment.
• Screen attachment. The screen panel attachment method (spline, channel, or fasteners) meets the debris-impact and pressure requirements for the applicable wind zone.

Post-storm screen repairs

After every hurricane, we write screen enclosure letters for rebuilds and partial repairs. The forensic side — which panels were storm-damaged vs. pre-existing wear, what’s repairable vs. what requires full replacement — ties to our colleagues at HurricaneInspections.com. Their forensic walkthrough approach documents the scope for both the insurance claim and the repair permit.

The combined package — forensic damage report plus repair engineer letter — is the fastest path from “my cage is wrecked” to “permit closed, claim paid, repair certified.”

When the letter is straightforward

If you have an as-built enclosure from a reputable manufacturer (Aluco, Mid-Florida, Sunesta, etc.), the permit drawings approximate the as-built, and the installation matches the drawings — the engineer letter is a routine inspection and seal. Most close in 24–48 hours.

If the enclosure was built without a permit or to non-standard details, we can often still certify it after a more invasive investigation, sometimes with specific reinforcements. Contact our intake team if you have a screen or pool enclosure situation that needs a PE.
