Use the actual product weight
Obtain the weight per installed square from the manufacturer. Tile size, profile and construction vary; a generic material weight is not a structural assessment. Include accessories and the rest of the roof assembly.
Review the existing building
Ask a qualified design professional to assess the roof framing and its support when the project requires it. Existing damage, alterations and unusual spans can affect the answer.
Include local design loads
The selected roof assembly must be considered with the loads applicable to the building. Product selection alone does not establish that the structure can support a change.
Before ordering
Keep the written structural recommendation with the project documents. Ask the contractor to coordinate any required repairs or reinforcement before the tile arrives.
