The answer depends on the length of your single span.
Due to the age of many roofs in need of repair, you’ve likely found that there are no drawings or design data available for the building to help you choose the correct roof deck gauge for your patch repair. Even though you don’t know the service capacity required by the original design, the table below will help you to determine the maximum distances that Roof Decks can safely span during construction. Maximum construction spans for floor decks depend on the depth of concrete you’re pouring, so please call us with that information and we’ll help you figure out what you need.'
Finally, note that the number of spans your deck covers impacts allowable construction spans and service load capacities differently:
• Roof Deck maximum construction spans DO NOT increase after you cover two spans • Roof Deck service load capacity DOES increase after two spans • Floor Deck maximum construction spans DO increase after two spans • Floor Deck service load capacity DOES increase after two spans
