How to Choose a Roofing Contractor in Green Bay

A roof is a five-figure purchase you will live under for decades. The contractor matters more than the shingle brand — identical materials installed well versus poorly produce entirely different roofs. Here is how to tell them apart before you sign.

Verify insurance and local presence

Ask for certificates of liability and workers compensation — and a physical local address, not just a PO box or out-of-state plate. Storm-chasing crews leave town with your warranty.

Demand a written, line-item scope

Tear-off depth, decking replacement terms and per-sheet pricing, underlayment type and coverage, ice-and-water locations, flashing rebuilds (not reuse), ventilation changes, material lines and colors, cleanup standard, and warranty documents. Vague proposals hide vague work.

Ask about flashing and ventilation specifically

These two details separate professionals from installers. "We reuse flashing where possible" and silence on ventilation math are disqualifiers — they are the most common leak and premature-failure causes we inherit.

Check references the right way

Ask for recent local jobs plus one from three to five years ago — longevity evidence. Drive by if invited. Read reviews across platforms, and note how the company responds to negative ones.

Compare warranties in writing

Material warranty (manufacturer, registered, what tier) plus workmanship warranty (duration, what it covers, who honors it). Our standard: 10-year workmanship plus registered manufacturer coverage.

Red flags that should stop you

Door-to-door pressure after storms, demands for full payment upfront, no written scope, cash-only pricing, unwillingness to pull permits where required, and estimates far below every competitor — the difference comes out of your roof.
