When framing is touched, call for a rough inspection while the opening, header, and flashing are still visible.

A final inspection will confirm tempered glass where needed, correct operation, and weatherproofing details.

Inspectors appreciate clean, visible flashing, proper pan or sill flashing, and head flashing integrated with the WRB, not just caulk on the face.

Local Factors That Affect Permit Decisions and Product Choice
