Commercial Reroofing in Green Bay, WI
Full Reroof Scopes for Green Bay's Mills, Plants, and Distribution Buildings
A reroof on a Fox River paper mill or a food processing plant is a different job than patching a strip mall. We scope full reroofs against production schedules, snow load, and the membrane a building's use actually calls for, then price the work by the square foot so ownership can budget against it before a shovel touches the roof.
Recover, Overlay, or Full Tear-Off: How We Make the Call
The deck inspection decides the path. If moisture scans and core cuts come back dry and the existing insulation still meets code minimums, a recover or overlay system can save the demolition and disposal line on the estimate. If the deck is wet, delaminated, or the insulation has lost R-value, tear-off is the only honest answer.
We don't sell a recover just because it's cheaper up front. A recover over a roof with trapped moisture fails faster than the membrane it's covering, and the second failure costs more than the first tear-off would have. We put the moisture survey findings in writing before we quote either direction.
Cost difference between the two paths typically runs wide enough to matter for a capital budget, which is exactly why we itemize tear-off, disposal, and deck repair as separate line items rather than folding them into one number.
Sequencing Reroofs Around Production and Cold Chain
Food processing plants around Green Bay don't stop running because a roof needs work. We phase tear-off in sections over occupied production lines, closing each section with temporary dry-in before the crew moves to the next, so a plant running cheese or meat processing lines never loses a shift to weather exposure.
Cold storage buildings need a different kind of care. Pulling a vapor-closed membrane off a freezer roof invites interior condensation the moment warm, humid air meets a cold slab below. We schedule those tear-offs in smaller daily sections and coordinate start times with the plant's refrigeration engineer rather than only our own crew calendar.
Paper mills along the Fox River corridor run continuous process lines too. Staging cranes and material hoists has to work around active loading docks and rail spurs, so we walk the site logistics with facilities staff before we ever price the labor hours.
Snow Load and Insulation Upgrades During a Reroof
A lot of the built-up roofs we tear off in this market were insulated to a code standard that's decades old. A reroof is the one time insulation is fully exposed, so we price a tapered ISO package sized to current ground snow load requirements rather than just matching what was there.
Parapets and roof edges are where ice damming does its damage every winter. During the reroof we rework crickets behind rooftop units and mechanical curbs so meltwater has somewhere to go instead of backing up against a wall and finding a seam.
What a Full Reroof Scope Includes
- Tear-off to the structural deck, with disposal hauled off same day
- Deck inspection and repair or replacement of damaged panels
- Insulation package sized to current snow load and R-value code
- New membrane system matched to the building's use and roof traffic
- Flashing, edge metal, and coping detail work at every penetration
- Drain and scupper upgrades where existing capacity is undersized
- Manufacturer field inspection before the warranty is issued
Budgeting a Reroof by the Square Foot
We quote reroofs in dollars per square foot so a facility manager can compare our number against internal capital planning without translating line items first. Lifecycle cost matters more than sticker price here: a system priced lower per square foot but rated for a shorter service life can cost more once you amortize it over 20 years against a system built for 30.
For multi-building campuses, like a mill with several roof sections on different replacement cycles, we'll phase the scope across budget years and hold pricing on the later phases so the whole project doesn't get re-quoted from scratch every spring.
Reroof Questions Green Bay Facility Managers Ask Us
How long does a full tear-off take on a 50,000 square foot roof?
Weather and deck condition drive the schedule more than crew size does. A dry deck with straightforward flashing detail typically moves faster than a roof with extensive rot repair or complex penetrations, and we build the schedule around actual site conditions once we're up there, not a generic estimate.
Can you reroof over an operating cold storage building without a temperature excursion?
Yes, but it requires phased tear-off in small daily sections with temporary dry-in closing each section before we open the next. We coordinate the schedule with your refrigeration engineer so the interior never sits exposed longer than the plan allows.
Does a reroof reset our manufacturer warranty or extend an existing one?
A full tear-off and new system installation starts a fresh manufacturer warranty term. A recover or overlay may carry different warranty terms depending on the manufacturer's requirements for the existing substrate, which we'll spell out in the proposal before you sign anything.
How early in spring can a tear-off start with bay ice still breaking up?
Membrane adhesives and seaming have minimum temperature requirements, so we watch the forecast rather than the calendar. Most years that means late March or April starts are workable, but we won't seam a membrane in conditions the manufacturer's spec sheet rules out.
What happens if a heavy snow event hits mid-reroof?
We close out exposed sections with temporary protection before a storm and don't leave a deck open overnight if snow load is forecast. Winter reroofs are staged in smaller daily sections specifically so a surprise system doesn't catch us with more open roof than we can protect.
