Poplar for roof decking

chemicalFam | Posted in General Questions on

Would poplar lumbar be a good alternative to plywood for roof decking?

Looked into Magnesium boards (Dragon board) but seems that might corrode metal shingles.

Anyone have any experience with those products?

    Poplar lumber is typically Liriodendron tulipifera, or the Tulipwood tree, especially when bought at lumberyards. Small northern mills might offer Populus tremuloides, a type of aspen sometimes called Popple. Either one would work fine for roof sheathing but your municipality may require a material graded for sheathing. Here in New England it's somewhat common to use white pine or other softwood for sheathing, and it used to be the only way to sheathe a building.
