Commercial Roofing Contractor in Indianapolis, IN Built for Hail, Ice & Heat

Hail bruises single-ply membranes and crushes or fractures the insulation and cover board underneath. From the surface, the roof often looks intact. Below it, the facer bond is broken, the membrane is stressed, and it's waiting for the next freeze-thaw cycle to split it open.

Why it's common: Hail moves through Marion, Hamilton, Hendricks and Johnson counties every year, mostly between March and June when severe-weather watches are routine. A lot of warehouse and office-park roofs use thin TPO over polyiso with no cover board, and that assembly is the most vulnerable to fractures. Indiana insurers expect a documented date of loss and timely reporting, so owners who wait until a leak finally shows up can lose coverage they were entitled to.

Locally: We see it most often on large TPO warehouse roofs in Plainfield, Brownsburg and Greenwood, and on 1990s office parks around Castleton and Keystone at the Crossing. On those big open roofs, one storm cell can damage several hundred thousand square feet at once.

Our fix: We do core cuts and a moisture or infrared survey, document everything with photos and a claim-ready report, then make targeted repairs or plan a replacement based on how widespread the damage is.

Ponding is water that's still sitting on a roof 48 hours after rain stops. It adds a lot of weight, speeds up membrane aging, feeds algae, and finds its way into any open seam. In winter it freezes and pushes laps and flashings apart.

Why it's common: A lot of the mid-century strip centers and masonry buildings in Indianapolis were framed dead-flat, with no tapered insulation. Decks sag over time, and leaves or debris clog internal drains and scuppers. Spring convective storms can drop far more rain in a short time than older drainage was designed to handle. Freeze-thaw cycles then turn standing water into ice that splits seams.

Locally: It's common on 1960s–70s strip centers along Washington Street, Emerson Avenue and Madison Avenue, on Mile Square masonry buildings with internal drains, and on church additions where a newer flat roof was tied into an older building.

Our fix: We correct the slope with tapered insulation or crickets, clear and resize the drains or add overflow scuppers, then repair or recover the membrane so water actually leaves the roof.

Seams, laps and perimeter flashing are the joints in a roof system, and they're where most leaks start. Thermal movement loosens termination bars, splits EPDM seam tape, and pulls counterflashing away from parapet walls.

Why it's common: Roof surfaces in Indianapolis can swing well over 100°F between summer and winter. Every season of expansion and contraction stresses adhesive seams, especially on 1980s–90s EPDM where the original seam tape or adhesive has dried out. Derecho winds then go after any perimeter that's already loose and peel it back.

Locally: We find this all the time on aging EPDM over schools, churches and medical offices in Lawrence, Carmel and Greenwood, and on parapet-heavy older buildings downtown and in Fountain Square.

Our fix: We re-seam with compatible primers and cover strips, reset or replace termination bars and counterflashing, and install new coping that meets wind-uplift requirements.

Rooftop HVAC units, gas lines and conduit all pass through the roof. Pitch pans dry out, curb flashings crack, and service technicians walking the roof puncture the membrane around the equipment.

Why it's common: Retail, medical, restaurant and warehouse buildings around Indianapolis carry a lot of rooftop equipment. HVAC crews are up there several times a year for summer cooling and winter heating service. Every visit adds foot traffic, dropped screws and panel edges set down on the membrane, and the shrink-swell cycle keeps working pitch-pan filler loose.

Locally: It's especially common in strip centers in Southport and Avon, restaurant pads along US-31 in Carmel, and distribution centers on the Mt. Comfort corridor where dozens of RTUs sit on a single roof.

Our fix: We replace pitch pans with prefabricated sealed boots, re-flash the curbs, and add walkway pads so service traffic doesn't wear through the membrane.

Ice builds up at gutters, scuppers and internal drains and blocks the water from melting snow. That water backs up under flashings, into wall cavities, or over the parapet, which leads to interior leaks and extra structural load.

Why it's common: Central Indiana's snow comes in repeated small rounds with freeze-thaw cycles in between, plus occasional ice storms. Heat escaping from under-insulated older buildings melts snow during the day, and it refreezes at cold edges overnight. Drifts collect against parapets and RTUs and hold even more meltwater against vulnerable details.

Locally: We see it on older masonry and mixed-use buildings in Broad Ripple and Irvington, on sloped-roof sections of churches and offices in Zionsville and Fishers, and on warehouse gutters along the I-74 corridor.

Our fix: We safely remove ice and snow, clear the drains, install heat cable where it makes sense, and fix the insulation and ventilation problems that cause the dams in the first place.

High winds lift membrane edges, metal coping and panels, and sometimes peel back whole sections of roof. Once the edge lets go, rain gets straight into the building.

Why it's common: Indianapolis sits at the edge of the Midwest severe-weather corridor. Straight-line wind events like the 2012 and 2022 derechos, along with tornado-warned storms between March and June, put enormous uplift on roof edges. A lot of older roofs went on before current ASCE 7 attachment standards, so their perimeters are under-fastened.

Locally: Large exposed roofs in the Plainfield/AllPoints corridor, Park 100 near Eagle Creek, and Speedway's hospitality and motorsports buildings take the brunt of straight-line winds coming across open ground.

Our fix: We do emergency tarping and temporary securement right away, document the damage for your insurer, then rebuild the edge with uplift-rated attachment.

On older pre-engineered metal buildings, the exposed fasteners lose their washers, the panel laps corrode, and rust eventually eats through the steel. The result is pinhole leaks and fasteners backing out.

Why it's common: Indianapolis's humid summers and road salt carried on winter air speed up corrosion. Daily thermal movement works exposed screws loose. Plenty of 1980s–90s light-industrial and agricultural-style buildings around the metro still have their original corrugated or R-panel roofs.

Locally: Common on light-industrial buildings in Park 100, in Mooresville and Camby, and on older shop and warehouse buildings near Lawrence and Fort Benjamin Harrison.

Our fix: We replace fasteners, seal the laps, treat rust, and apply a restoration coating. When corrosion is too far along, we install a standing-seam or new steel panel retrofit.
