Choosing Your Metal Roof: Climate & Architectural Match Guide
Choosing the right metal roof is a balance between technical specs and your home’s needs. Key factors include snow load capacity, corrosion resistance, and adherence to historic preservation rules. These elements help determine the best metal roofing systems for your area.
Snow Belt Solutions: Engineering for Weight and Ice
In northern climates, metal roofs must handle heavy snow. The spacing between ribs is critical for load capacity:
- 24-inch spacing: Supports 50 pounds per square foot (psf) – ideal for areas with frequent heavy snowfall
- 36-inch spacing: Handles 35 psf – suitable for moderate snow regions
Preventing ice dams starts with specialized coatings. PVDF coatings, for example, help snow slide off, preventing ice dams from forming.
Coastal Combat: Winning the Rust War
Coastal areas require alloys with strong corrosion resistance. Look for materials tested under ASTM B117 standards. These tests simulate 5+ years of coastal exposure in a lab:
| Material | Salt Spray Resistance | Maintenance Needs |
