The rules for a reroof in Bolton

Layers

Two layers means a tear-off

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). 40% of Bolton’s homes were built before 1980; many have been reroofed before.

Ice barrier

Required statewide

The state’s climate table marks the ice barrier “yes” statewide. That is a self-adhering membrane, or two cemented layers of underlayment, from the eave to at least 24 inches inside the wall line (IRC R905.1.2).
