Four Roof Systems, Plus Full Tear-Off When A Roof Is Done
Our commercial roofing services in Portage cover TPO, EPDM, industrial, and metal roofs, and full replacement when an old roof has nothing left to repair.
A white thermoplastic sheet with hot-air welded seams. It suits low-slope retail, office, and warehouse roofs that run cooling all summer and see regular service traffic. Welded seams make later repairs bond to the original sheet.
Black rubber membrane, fully adhered or ballasted, with taped seams. It handles hard freezes and crowded penetrations, and later patches are simple. Older rubber roofs often take new EPDM after one tear-off.
Thicker membranes, crush-resistant cover boards, curb flashing, and walkway pads for plants and warehouses where heat, residue, and equipment wear on the roof. Sections are replaced while production keeps running below.
Standing-seam and exposed-fastener panels for pitched roofs, shops, and farm buildings, plus retrofit framing over worn flat roofs and fastener and flashing repair. Pitched panels shed lake-effect snow instead of holding it.
Commercial Roof Replacement in Portage, From Deck Up
When repairs stop holding, the old roof comes off and a new system goes on, one section at a time.
Replacement starts with core cuts and a moisture survey to find wet insulation and weak deck. The old layers come off in sections sized to one day, the deck is repaired, and new tapered insulation goes down before the membrane or panels.
Retail centers, plants, and warehouses stay open while we work. Each section is closed before the crew leaves, and loud work is set around store hours and shifts. Interior protection goes up under any section opened above stock, equipment, or desks.
Rusted or soft deck replaced while the roof is open
Wet insulation removed and replaced
New slope built toward the drains
New edge metal and coping at every wall
Membrane Choice
TPO or EPDM: Choosing a Membrane in Portage
Most low-slope roofs here end up with one of these two sheets. Here is how they compare on the details owners ask about.
TPO Leads When
A white surface helps cool the space below.
Seams face heavy wear and need to be welded.
Service crews cross the roof often.
The building sits in summer sun with high cooling loads.
Repairs should weld into the original sheet years later.
EPDM Leads When
The roof needs to stay flexible through deep cold.
Many pipes and curbs crowd the field.
Owners want quick taped patches later.
Ballast is an option on a strong enough deck.
A dark surface is fine for unheated storage below.
Roof Past the Point of Patching?
Call and tell us how many leaks you have chased this year. Several leaks in different spots usually means it is time to price a new roof.
Our Commercial Roofing Services in Portage, From Visit to Closeout
Every system follows the same five stages, with details changed for the roof.
Step 1
Inspect And Survey
A roof walk, core cuts, and a moisture survey show the layers, the insulation condition, and the deck before any system is chosen. Leaks reported inside are traced back to where they enter.
Step 2
Write The Scope
You get a written scope naming the system, thickness, insulation, edge metal, and every flashing detail, with the order of work and the parts of the building each step affects.
Step 3
Prepare The Building
Interior protection, crane days, and delivery routes are set around tenants, shifts, and the dock schedule, and every tenant gets dates before work starts.
Step 4
Build The New Roof
Sections are torn off, repaired, insulated, and covered daily, with seams welded or taped and flashing finished as the field goes down. Nothing is left open overnight.
Step 5
Inspect And Hand Over
Seams are probed or hand-checked, drains are cleared, and you get photos of every detail from the final roof walk, along with the product and warranty paperwork from the manufacturer.
Commercial Roofing Services in Portage: Common Questions
How do I know when to replace a commercial roof?
Leaks in many places each year, patches on patches, wet insulation across large areas, and membrane pulling away from walls all point to replacement. A moisture survey shows how much of the roof is still dry. If most of it is dry, a recover over the old roof can be an option worth pricing.
Which roof system fits a Portage port warehouse?
Big low-slope warehouse roofs usually take TPO or EPDM over rigid insulation, with metal on any pitched sections. Wide rolls cut down the number of seams, and tapered insulation moves water to the drains. Tear-off is phased around dock schedules so trucks keep moving.
Can one building have more than one roof system?
Often it does. A plant might have metal over the production bays and TPO over the office wing. Each section gets the system that fits its slope and use, with flashed joints where they meet. Those joints are where we look first when a mixed roof leaks.
How long does a commercial roof replacement take?
Roof size, layers to remove, deck repair, and weather set the timeline. We open only what can be closed each day, so the building stays dry from start to finish.
Do you repair roofs or only replace them?
Both. Seam welding, taped seam repair, flashing, fastener work, and patches are part of the job, and we tell you when repairs still make sense over a new roof. A repair that buys several dry years often beats a replacement the building does not need yet.
Can a flat roof be converted to metal?
Yes, with retrofit framing. Purlins or light framing go over the old flat roof to build slope, then metal panels go on top. An engineer checks the structure first, and the old roof has to be dry so moisture stays out of the new assembly.
What happens to the old roofing materials?
Torn-off membrane, insulation, and metal go straight from the roof into covered dumpsters or trucks, so loose debris stays off parking lots and loading areas. Scrap metal is separated for recycling wherever a yard will take it.
What does the written scope include?
The system and membrane thickness, insulation type and thickness, tear-off or recover, deck repair allowances, edge metal, every flashing detail, drain work, and the order of work around your building. It also lists what stays the same, so nothing is left to assumption.
