Snow. Green Bay's design ground snow load is 40 psf, a third higher than Madison's or Milwaukee's, and long winters make ice dams a routine risk. Wisconsin's dwelling code requires ice-dam protection on low-slope eaves over heated space, and a good Green Bay quote accounts for membrane, ventilation and flashing, not just shingles.
Layers matter as well. Wisconsin code won't allow a new roof over two existing layers or a deteriorated roof, so older roofs often need a full tear-off. Ask each roofer how many layers they found.

Permits and contractor registration in Green Bay
Green Bay is unusual among larger Wisconsin cities: a typical house reroof needs no permit. The city requires one only for buildings with three or more units or for homes in a historic residential district. Where a permit is required, the fee schedule lists a flat $100 for roofing replacement.
No permit also means no inspection, so credentials carry more weight. Wisconsin requires a Dwelling Contractor Certification to pull permits, and Green Bay registers residential building contractors working in the city. Ask for both. See how to choose a roofing contractor.

Pro tip from our network contractors
Without a city inspection, ask your Green Bay roofer to photograph the deck, ice-dam membrane and flashing before the shingles go on, and to note the membrane width on the invoice. It takes them five minutes and gives you proof for any warranty or insurance claim.
