The rules for a reroof in Warren

Permit

Expect a building permit

Massachusetts exempts sheds, fences and finish work from permits (R105.2), not roofing. In Warren the building department takes the application, with the contractor’s home improvement registration on it.

Layers

One old layer can stay; two cannot

A new roof may go over one existing layer; with two or more, or over slate, clay or cement tile, everything comes off to the deck (IRC R908.3.1.1). 54% of Warren’s homes were built before 1980, so count the layers before comparing quotes.

Ice barrier

Required statewide

Massachusetts answers “yes” to the ice barrier for every town. 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.

Wind and snow

116 mph design wind, 40 psf ground snow

Warren’s code design values are a 116 mph ultimate design wind speed and a 40 psf ground snow load (35 psf minimum flat-roof snow load). At that wind speed the code calls for asphalt shingles labeled ASTM D7158 Class D, G or H (Table R905.2.4.1).

The housing is 57% detached houses, 15% buildings of two to four units, 7% manufactured homes.

Older houses hide their history: ask the contractor to confirm the deck (board or sheet) and every layer above it before pricing, because slate or two layers mean a full tear-off.
