Exploring Roof Deck Types

Roof decks serve as the structural foundation for asphalt shingle roof systems, playing a crucial role in the overall durability and longevity of your roofing solution. Before diving into the variety of roof decks available, it is essential to engage the expertise of various parties, including general contractors, deck contractors, architects, engineers, designers, and owner representatives. Their collaboration ensures a thorough inspection of the deck surface, verifying its cleanliness, dryness, smoothness, and readiness for roof system application.

Here are five different types of roof decks:

1. **Wood Panel:**
– Plywood Panels: Composed of thin wood layers, or veneers, laid at right angles and glued together for strength and stability. Minimum four-ply thickness is recommended for plywood used as a roof deck material.
– OSB Panels: Composed of compressed, glued wood strands oriented at right angles, with recommended nominal thicknesses of 1/2-inch for plywood and 5/8-inch for OSB when used as roof deck material.

2. **Preservative-Treated Panels:**
– Caution is advised when using wood treated with oil-borne preservatives, and consultation with roofing materials manufacturers is recommended for specific application guidelines.

3. **Fire-Retardant-Treated Panels:**
– Special care is necessary due to potential deterioration caused by heat-induced activation. A thorough analysis of the building envelope is crucial when considering fire-retardant-treated wood panel decks.

4. **Wood Planks and Wood Boards:**
– Composed of solid-sawn dimensional lumber, differentiated by thickness and width. Wood planks, ranging from 2 to 5 inches thick, may be single or double tongue-and-groove, ship-lapped, or grooved for splines.
