The rules for a reroof in Gill

A permit from Gill

The residential code’s permit-exempt list (R105.2) has no roofing line. Gill’s building department issues it, and the application carries the contractor’s HIC registration number.

Layers

No third layer

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). 62% of Gill’s homes were built before 1980, so count the layers before comparing quotes.

Ice barrier

Required in Gill, as in every Massachusetts town

The state’s climate table marks the ice barrier “yes” statewide. 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.

What goes on the roof next

Material	HUD useful life	Fits a house like	Watch for

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; 27% here predate 1940	Can’t be roofed over; check the framing for the weight
Flat roof: EPDM or TPO	15 years	Porches, additions, low-slope rears	Coating is not a replacement
