    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.
