Permit
Roofing is not exempt
Roofing is not on the Massachusetts list of work exempt from a permit (780 CMR 51.00, R105.2). In Norton the building department takes the application, with the contractor’s home improvement registration on it.
Norton has 6,791 homes, and half of them were standing by 1982. The rules below decide how much of the old roof has to come off and what goes under the new one.
New Roofing Costs connects homeowners with independent local roofing contractors. We do not perform roofing work.
This number connects homeowners who are planning a new roof or a full roof replacement with independent local roofing contractors. It is not for leak repairs or patch jobs. The call must come from the homeowner who decides on the roof. Calls may be recorded.

Layers
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). 46% of Norton’s homes were built before 1980, so count the layers before comparing quotes.

Ice barrier
Massachusetts answers “yes” to the ice barrier for every town. Membrane or doubled underlayment, eave to 24 inches inside the wall line (IRC R905.1.2), is a line on every quote here.

Wind and snow
Norton’s code design values are a 124 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).

A report says hail fell near Norton, not that it damaged a roof. When wind or hail damage means a new roof.
HUD’s useful-life figures are for planning; a warranty is a separate promise. For Norton’s houses: More in the guides to shingles, metal, slate and flat roofs.
| Material | HUD useful life | Fits a house like | Watch for |
|---|---|---|---|
| Asphalt shingles | 20 years | Most pitched roofs; 69% of homes here are detached | Class G or H at 124 mph design wind (IRC Table R905.2.4.1) |
| Metal (standing seam, panels) | 50 years | Low pitches and long runs | Standing seam that carries its own loads can skip the tear-off (R908.3.1) |
| Slate | 75 years | Older houses; 11% here predate 1940 | Never a base for a new layer (R908.3.1.1); heavy |
| Flat roof: EPDM or TPO | 15 years | Porches, additions, low-slope rears | Coating is not a replacement |

The price side is in what a new roof costs in Massachusetts; the paperwork side in checking a roofing contractor.
