Can a tongue and groove floor panel be used for a roof application?
A common misconception is T and G flooring panels (Floor Span) cannot be used for roofing applications. Table 2 in ER-5637 NER-133 lists allowable live loads for Floor Span panels used for roofing applications. It should be noted that sheathing panels (Sheathing Span) used for roofing applications have different design capacities than Floor Span panels. Note: Flooring panels are sanded and may not provide adequate slip resistance.
