When does a roofing / re-roof need a permit in City of Sammamish?
Whether a re-roof needs a building permit is set by each city's own administrative code (the chapter it adopts with the residential code), and cities differ: some exempt a roof recover or a like-for-like replacement, some require a permit only when the sheathing is modified or replaced, and some require one for every re-roof. Kolmo has not verified this city's rule; ask its building department. Re-roofing requirements themselves are in IRC R908.
