We have been doing roofing installation out of Garfield for 25+ years. Fairfield is 9.3 miles west of the shop, in Essex County — well inside the area we work in regularly rather than the edge of it. Either way we still answer when you call about the job two winters later, which is the part that actually depends on being local.
A new roof is a system rather than a covering: decking, underlayment, ice and water membrane at the eaves and valleys, flashing at every junction, then the shingles or membrane, with intake and exhaust ventilation designed in from the start.
Essex spans dense urban Newark and the Oranges, with a great deal of pre-war multi-family stock, through to Montclair, Glen Ridge and South Orange, where Victorians and 1900s colonials with real exterior detail are common, and out to postwar suburbs in the west. New roofing usually has to meet something older — an addition tying into the existing roof, a dormer cut into it, a garage sitting alongside. The join is where these leak, so the flashing detail at that junction matters more than which shingle you choose.
The quote names the underlayment, the ventilation and the flashing rather than just the shingle and a colour. Permits and inspections are ours to arrange, and both the workmanship and manufacturer warranties are handed over on the day we finish.
