The rules for a reroof in Marion

Permit

A permit from Marion

Roofing is not on the Massachusetts list of work exempt from a permit (780 CMR 51.00, R105.2). Marion’s building department issues it, and the application carries the contractor’s HIC registration number.

Source: 780 CMR 51.00, Chapter 1 amendments (R105)

Layers

No third layer

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). 68% of Marion’s homes were built before 1980; many have been reroofed before.

Ice barrier

Required in Marion

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).

Wind and snow

129 mph design wind, 30 psf ground snow

Marion’s code design values are a 129 mph ultimate design wind speed and a 30 psf ground snow load (30 psf minimum flat-roof snow load). At that wind speed the code calls for asphalt shingles labeled ASTM D7158 Class G or H (Table R905.2.4.1).
