Date: 10-08-2026
Prepared by: Azeb Hailu
The Scope of work should meet requirements based on the following DoW/ US Navy specifications and gridlines and national standards: UFC 3-110-03: Roofing
UFC 1-200-01: DoD Building Code
UFC 3-301-01: Structural Engineering
UFGS 07 71 00: Roof Specialties and Accessories
UFGS 07 60 00: Flashing and Sheet Metal
UFGS 01 33 00: Submittal Procedures
SMACNA: Architectural Sheet Metal Manual (7th Edition), Chapter 1 (Gutters and Downspouts). ASCE/SEI 7: Minimum Design Loads and Associated Criteria for Buildings and Other Structures (wind and snow load provisions). ASTM A240/A240M: Standard Specification for Chromium and Chromium-Nickel Stainless Steel Plate, Sheet, and Strip. ASTM B209: Standard Specification for Aluminum and Aluminum-Alloy Sheet and Plate. ASTM B370: Standard Specification for Copper Sheet and Strip for Building Construction.

Based on these standards the gutter guard must meet the minimum requirements of the following: must consist of rigid metallic frames supporting heavy-duty mesh screens designed to prevent pine needles, oak tassels, deciduous leaf debris, and pests from entering gutters while permitting maximum hydraulic transfer. Components must exhibit high corrosion resistance. All raw cut edges, fasteners, and mesh frames must pass a minimum 1,000-hour salt spray test per ASTM B117 without blistering, flaking, pitting, or red rust. Assemblies must be engineered and mechanically secured to resist wind forces determined in accordance with ASCE 7, Min 115mph (This will depend on the location of the Base. Waterfront is much windier). Friction-only or press-fit friction tabs without mechanical fastener backups are strictly prohibited in exterior wind-exposed areas. Minimum water throughput capacity: 150 inches of rainfall per hour. Assemblies must accommodate linear thermal expansion and contraction over an ambient range of -10°F to 110° shearing fasteners. Plastic, PVC, vinyl, nylon, and open-cell polyether/polyurethane foam inserts are prohibited. Approved materials are:
Stainless Steel Micro-Mesh with Extruded Aluminum Subframe • Frame: Extruded architectural aluminum alloy 6063-T5 or 6005-T5, minimum thickness 0.050 inch (1.27 mm). •Finish: Factory-applied architectural grade anodized (AAMA 611 Class I) or thermo-set fluoropolymer resin finish (AAMA 2605, PVDF 70% Kynar 500) matching existing gutter/fascia color. • Mesh Screen: Marine-grade Type 316 stainless steel (or Type 304 for non-saline interior zones) woven wire cloth, plain weave.
