As a Portage commercial roofing contractor, we install TPO, EPDM, industrial, and metal roofs on warehouses, plants, offices, and retail centers across Porter County.
Most Portage commercial roofing calls start with one of these five problems, spotted inside the building or up on the roof.
Water entering at an open seam, a split pipe boot, or flashing pulled loose at a curb, then running along the deck before it drips.
We trace the path from the stain back to the entry point, repair that seam or flashing, and check the insulation around it.
Sagging deck, crushed insulation, or drains set higher than the field around them, a common pattern on older warehouse roofs.
We map the low areas, then build tapered insulation or crickets into the reroof so rain and snowmelt reach the drains.
Older EPDM shrinks with age and drags its flashing off parapets and curbs, opening gaps at the base of each wall.
We replace the shrunken flashing. When the field membrane is drum-tight across the whole roof, we price a new system instead of more patches.
Loose fasteners, open laps, and cut edges, which corrode faster in the damp air coming off Lake Michigan.
We reset or replace fasteners, seal the laps, and swap panels that have rusted through, or quote a new metal roof when the damage is widespread.
Drifted snow parked against a taller wall, with meltwater climbing above flashing that was set too low.
We raise the flashing height on the next reroof and recheck the counterflashing and coping along those walls.
The first visit answers one question before any price: can this roof be repaired, or does it need a new system? These are the signs we weigh.
Every roof we price lands in one of three columns. Each column links to the systems we install for that condition.
Seam welding, new flashing, fastener work, and patches that match the existing membrane, for roofs with dry insulation and a few clear leak points.
Signs You Are Here
A new membrane or metal system installed over the current roof, once core cuts confirm one dry layer and a deck strong enough to carry it.
Signs You Are Here
Tear-off to the deck, deck repair where it is needed, new insulation, and a new TPO, EPDM, or metal roof, phased so the building stays open.
Signs You Are HereCall and tell us where the stain sits and what is above it on the roof, such as a unit, a drain, or a wall. That tells the roofer where to start.
Five stages run on every job we take, from the first core cut to the final roof walk with you.
We walk the whole roof, photograph seams, drains, curbs, and edges, and cut small cores to read the layers and see whether the insulation is dry. Leaks reported inside get traced from the ceiling up.
Slope, drainage, rooftop traffic, and the layers already in place decide between TPO, EPDM, and metal. You get a written scope naming membrane thickness, insulation, and every flashing detail we plan to change.
Delivery dates, dock schedules, store hours, and production shifts set the order of work. Materials go up by crane or lift to the area being roofed, and sections over occupied space get interior protection.
Each section is torn off, repaired at the deck, insulated, and covered before the crew leaves for the day. Seams are welded or taped, and curbs, walls, and drains are flashed as the field goes down.
Welded seams are probed, taped laps are checked, and debris is cleared from drains and gutters. The final roof walk with you covers every penetration and the photos that go into your building file.
A new roof does different work on a steel plant than on a storefront. Here is what owners gain on the buildings we roof most.
Wet boards get cut out and replaced during tear-off, so the new membrane sits on insulation that holds its R-value and stops trapping water against the deck.
A white TPO surface reflects summer sun that a dark roof soaks up, which lowers roof temperature over offices and stores with heavy cooling loads.
Walkway pads on service routes, protected equipment supports, and thicker membrane around plant curbs cut down the punctures that start most industrial leaks.
Tapered insulation and crickets built into the new roof move rain and snowmelt to drains instead of leaving it in low spots for days.
Is your building near Portage? We install commercial roofs across the towns below; for anywhere else, call us or send us a message.
Office parks, medical buildings, and campuses where several roofs on one property get planned together.
Valparaiso commercial roofing →Lakefront buildings where wind pulls hardest at the roof edge, so perimeter attachment and edge metal come first.
Michigan City commercial roofing →Warehouses and plants with busy service routes across the roof, laid out with walkway pads and curb flashing.
Griffith commercial roofing →Retail, office, and industrial roofs scheduled around adhesive temperatures and the spring and fall weather windows.
Chesterton commercial roofing →Older shops and storefronts where we count the roof layers already in place before choosing recover or tear-off.
Lake Station commercial roofing →Ask each roofer for their City of Portage license, proof of liability and workers' compensation coverage, and a written scope listing tear-off, insulation thickness, membrane type, flashing, and drain work. Line the proposals up item by item. For a manufacturer warranty, confirm that manufacturer has approved the installer.
That comes down to the roof. White, heat-welded TPO handles heavy seam wear and keeps a roof cooler in summer. Black EPDM stays flexible in hard cold and patches easily. Roof size, foot traffic, drainage, and the layers already in place usually settle it.
Large low-slope warehouse roofs near the port usually get TPO or EPDM over rigid insulation, with metal on any pitched sections. We order wide membrane rolls to cut down the seam count, taper the insulation toward drains, and phase tear-off so trucks keep moving at the docks.
Yes. We work one tenant space at a time and close each section before leaving. Loud tear-off gets scheduled around store hours where possible, each space's rooftop units are reflashed as that section goes down, and interior protection goes up anywhere the deck is opened.
Price per square foot moves with the system and membrane thickness, how much insulation goes down, how many old layers come off, and how crowded the roof is with curbs and pipes. Small roofs and equipment-heavy roofs cost more per foot. We set the number after a free visit.
Old layers to remove, deck repairs, wet insulation, and the new system's thickness carry most of the cost. Flashing at walls, curbs, and drains adds to it, and so do crane access, roof height, and phasing around tenants or production lines. Each building gets its own free on-site estimate.
Heavy lake-effect snow bands off Lake Michigan have crossed Porter County, according to the National Weather Service. Snow drifts against parapets and taller walls, then melts for weeks. We set flashing high enough at those walls and build drainage so the meltwater runs to the drains.
Regularly. Valparaiso, Michigan City, Griffith, Chesterton, and Lake Station are all part of our service area, and each building there gets the same roof walk and core cuts. If your property is elsewhere in Northwest Indiana, call and describe the roof.
Send the property address and a line about the roof. We will set up a roof walk, cut cores, and price the work in writing.
