The rules for a reroof in Newton

Permit

A permit from Newton

The residential code’s permit-exempt list (R105.2) has no roofing line. The application to Newton’s building department carries the contractor’s HIC number (R105.3).

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

Layers

No third layer

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). 80% of Newton’s homes were built before 1980, so count the layers before comparing quotes.

Ice barrier

Required in Newton, as in every Massachusetts town

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

119 mph design wind, 40 psf ground snow

Newton’s code design values are a 119 mph ultimate design wind speed and a 40 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).

Homes and roofs in Newton

Of 32,194 occupied homes in Newton, 22,532 (70%) are owner-occupied. Counting by decade, 49% before 1940, 67% before 1960, 80% before 1980 of the housing was in place, and 12% dates from 2000 on. (ACS 2020–2024.)

The housing is 55% detached houses, 8% attached single-family houses (rowhouses, twins and townhouses), 21% buildings of two to four units.

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.

Of the 54 Middlesex County municipalities on this site, Newton has the 4th largest share of homes built before 1980: 80%, against a county range of 29% to 87%.
