Due to its weight – three times that of asphalt – roof rafters and roof sheathing need to be up to code to support slate’s heavy load. Slate can be placed over a layer of composition shingles only if the slope of the roof is 4-in-12 or more, and only if a structural engineer has confirmed that the roof framing can bear the weight of 7 pound per square foot.
