More, insulation, and all the way down to the roof deckComponents - A roof deck is the structural surface connected to a building’s framing that supports the roof system installed above it.

It helps determine what scope of work can be used on the roof, like whether a roof qualifies for a layoverInstallation – A layover (recover or overlay) is a method of installing a new roof membrane over an existing roof system without removing the existing roof. More or requires full replacement. For property owners, a core sample’s findings directly affect budgeting and the scope of work a repair or replacement might require.
