The rules for a reroof in Lowell

Permit

A permit from Lowell

Roofing is not on the Massachusetts list of work exempt from a permit (780 CMR 51.00, R105.2). The application to Lowell’s building department carries the contractor’s HIC number (R105.3).

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

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). 75% of Lowell’s homes were built before 1980; many have been reroofed before.

Ice barrier

Required statewide

There is no local exception: the state table says “yes.” 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, 50 psf ground snow

Lowell’s code design values are a 116 mph ultimate design wind speed and a 50 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 D, G or H (Table R905.2.4.1).

Homes and roofs in Lowell

43% of the occupied homes in Lowell are lived in by their owners: 18,669 households, the people this line is for. Counting by decade, 44% before 1940, 55% before 1960, 75% before 1980 of the housing was in place, and 10% dates from 2000 on. (ACS 2020–2024.)

The housing is 30% detached houses, 7% attached single-family houses (rowhouses, twins and townhouses), 27% 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, Lowell has the 10th largest share of homes built before 1980: 75%, against a county range of 29% to 87%.
