The rules for a reroof in Rockland

Permit

Roofing is not exempt

Massachusetts exempts sheds, fences and finish work from permits (R105.2), not roofing. The application to Rockland’s building department carries the contractor’s HIC number (R105.3).

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). 68% of Rockland’s homes were built before 1980, so count the layers before comparing quotes.

Ice barrier

Required in Rockland, as in every Massachusetts town

There is no local exception: the state table says “yes.” 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

123 mph design wind, 35 psf ground snow

Rockland’s code design values are a 123 mph ultimate design wind speed and a 35 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).
