    TECHNICAL MEMORANDUM

TO: Project File / Building Department
SUBJECT: Technical Specifications & Wind Uplift Compliance
PROPERTY ADDRESS:  Landon Cir, Boynton Beach, FL
DATE: April 20, 2026

1. PROJECT DATA SUMMARY
•	Mean Roof Height: 15'
•	Roof Pitch: 5/12
•	Roof Geometry: Hip Roof
•	Total Area: 40 Squares
•	Exposure Category: C (Open terrain/Inland)

2. PROPOSED ROOFING SYSTEM
The following components are engineered to function as an integrated assembly, ensuring structural integrity and a sealed building envelope:
Component	Product	NOA Number
Roof Tile	Eagle Capistrano (High Profile)	24-1008.07
Underlayment	Weather Armor (1 Layer, Direct-to-Deck)	25-0219.08
Adhesive	APOC Polyset AH-160	23-0614.01

3. DESIGN PRESSURE REQUIREMENTS
Based on the Simplified Roof Uplift Chart (ASCE 7-22) for a 15' Mean Roof Height in Exposure C, the following pressures are required for this structure:
•	Zone 1 (Field): -50.8 psf
•	Zone 2 (Perimeter): -70.1 psf
•	Zone 3 (Corners): -70.1 psf

4. REGULATORY COMPLIANCE & JUSTIFICATION
A. Underlayment System (1-Ply Weather Armor)
The use of one layer of Weather Armor (NOA 25-0219.08) applied direct-to-deck is compliant with the Florida Building Code (FBC) and Palm Beach County requirements.
•	Material: Glass-fiber reinforced, SBS modified bitumen membrane meeting ASTM D1970.
•	Code Justification: Per FBC 1507.1.1.1, a self-adhering polymer-modified bitumen underlayment qualifies as a Sealed Roof Deck and a Secondary Water Barrier.
•	Compliance: The NOA specifically approves this product for HVHZ use in single-ply application, providing superior monolithic protection and a robust bonding surface for adhesive-set systems.
B. Adhesive Attachment (APOC Polyset AH-160)
For a 5/12 pitch, the attachment must resist the overturning moment created by -70.1 psf pressures.
•	Attachment Protocol: To satisfy the -70.1 psf demand in Zones 2 & 3, the installer shall utilize a Large Paddy (min. 45g) or Dual Paddy placement as outlined in NOA 23-0614.01.
•	Tested Safety: The AH-160 system is TAS 101 tested and rated for high-velocity wind zones, ensuring the Eagle Capistrano tile remains secure under peak design loads.

5. INSTALLATION PROTOCOL
•	Surface Prep: Deck must be clean, dry, and free of debris.
•	Underlayment: Minimum 3-inch headlap and 6-inch end lap for a continuous seal.
•	Tile Setting: Tiles must be set firmly into the foam adhesive within the specified "string time" to ensure a minimum contact area of 2/3 of the tile's length.

6. CONCLUSION
The Proposed Roofing System is a fully compliant assembly engineered for the environmental demands of Boynton Beach. The selection of Eagle Capistrano tiles secured with APOC Polyset AH-160 over a Weather Armor secondary water barrier exceeds the structural and waterproofing requirements for a 15' Mean Roof Height in this jurisdiction.

    TECHNICAL COMPLIANCE MEMORANDUM

Project Overview & Design Criteria: This residential tile re-roof project in Boca Raton, FL, is engineered to withstand 170 MPH winds (Exposure C, 20' mean height, hip roof) in strict compliance with the FBC 8th Edition (2023), ASCE 7-22, and RAS 110 protocols.

Approved System Components: The high-performance assembly utilizes a Weather-Armor FT3 underlayment (NOA 25-0219.08) and Eagle Saxony 900 Low Profile roof tiles in Dark Charcoal Blend (NOA 24-1008.12). All components are securely bonded using APOC Polyset AH-160 Single Component adhesive (NOA 23-0614.01).

Engineering & Wind Compliance: The system vastly exceeds local wind load requirements. The Weather-Armor underlayment provides a maximum capacity of -112.5 psf, easily covering the maximum required corner and perimeter pressures of -63.5 psf. Furthermore, tile attachment moment calculations using a 24g medium adhesive pad deliver a substantial 18.2x safety margin in the field (Zone 1) and a 7.5x safety margin in high-pressure perimeter zones (Zones 2/3).

Summary: This roofing assembly significantly surpasses Boca Raton's structural wind mandates, providing 1.77x the required underlayment resistance and 7.5x the required tile attachment resistance. Final fastening includes 32-gauge metal tin caps on all underlayment laps per 170 MPH criteria, with installation following RAS 120 and RAS 109 protocols. Reviewed for code compliance.

    Key Project Highlights  

Premium Material Upgrade: Stripped the existing tile layers down to the wood deck and replaced them with a state-of-the-art Sentrigard ML150 standing seam metal panel system finished in a custom architectural blue protective coating.  

Engineered Wind-Uplift Defense: The 0.032" aluminum metal panel configuration is explicitly rated and securely fastened to conquer intense storm pressures, safely meeting extreme requirements of up to -128 PSF in localized high-stress roof zones. 

 Advanced Low-Slope Shielding: For the property's flat and transitional layouts, we integrated a custom CertainTeed multi-ply self-adhered framework featuring Flintlastic SA Ply Base and SA Cap sheets, clearing a massive structural threshold rating of -127.5 PSF. 

 Dual-Layer Secondary Barriers: Outfitted the structure with a heavy-duty Titanium FR Fire Barrier underlayment core. This secondary defense barrier delivers strict fire resistance and a watertight seal across the entire re-nailed 5/8" CDX plywood roof deck structure. 

 Elite Coastal Testing Standards: This engineered conversion system fully satisfies stringent Florida Building Code protocols, including TAS 100 for wind-driven rain defense and TAS 125 for extreme structural uplift resistance.
