Layers
One old layer can stay; two cannot
On a roof that already carries two layers, or slate or tile, the code allows no recover: it is a tear-off (IRC R908.3.1.1). With 55% of Westminster’s homes were built before 1980, ask what is under the newest layer.

Ice barrier
Required statewide
There is no local exception: the state table says “yes.” It runs from the eave to 24 inches inside the exterior wall, more on steep roofs (IRC R905.1.2); check that the quote lists it.
