The answer to 'best roof decking' is that plywood and oriented strand board (OSB) are the most common and recommended roof decking materials for residential homes. Plywood is a sturdy, water-resistant material made from thin wood veneers, while OSB is a engineered wood panel made from wood strands or flakes. Both provide a strong, stable base for the roof shingles or other roofing materials.
When choosing roof decking, it's important to select a product that meets local building codes and is rated for the appropriate roof span and load requirements. Plywood and OSB come in different thicknesses, typically ranging from 1/2 inch to 3/4 inch, with thicker panels providing more structural support. The decking should also be installed properly with the correct fasteners and spacing to ensure a durable, long-lasting roof.
