The two main residential metal roofing systems differ primarily in their fastening methods and resulting performance characteristics.
Screw Down Metal Roofs Explained
What Are Screw Down Metal Roofs?
Screw down metal roofing (also called exposed fastener systems) represents the most affordable entry point into metal roofing. These systems attach metal panels directly to the roof deck using visible screws with rubber washers.
How Screw Down Installation Works
Installation Process:
- Screws penetrate through metal panels into roof decking
- Rubber washers create weather seals around each fastener
- Panels overlap at edges with exposed seam connections
- Fastener spacing typically every 12-18 inches
Panel Specifications:
- Profiles: Corrugated or ribbed patterns for strength
- Width: 24-36 inches for efficient coverage
- Gauge: 26-29 gauge steel most common
- Materials: Primarily painted steel options
