Roof decking and sheathing are two terms that most roofers use interchangeably, often much to the confusion of homeowners. To help simplify and clear things up, today’s post from local roof repair expert Home Pro Exteriors, Inc. explains the distinctions between these two.

Whether plywood or OSB, the quality of sheathing material can significantly impact the longevity and performance of your roof.
