As an Indianapolis commercial metal roof repair contractor, we reset fasteners, reseal laps, and swap rusted panels on steel roofs over shops and warehouses.
Indianapolis commercial metal roof repair works best when the steel itself is still solid. This comparison shows where repair ends.
Leaks at screws, laps, and trim on panels that still hold weight.
Steel that has thinned to the point new screws cannot bite.
Metal roofs leak along predictable lines: screw rows, laps, and trim. These signs tell you which one is going.
Expansion and contraction back screws out until the washer no longer seals the hole.
Dried sealant at the overlap lets wind push rain sideways into the building.
End laps hold water and debris, so rust eats through there before anywhere else.
Brittle translucent panels split at their fasteners and leak at the curb.
Trim that rattles in wind has lost its closures and fasteners.
Condensation under bare panels can mimic a leak, so we check before patching.
Every metal roof detail has its own repair. We match profile, gauge, and color where the panels allow.
| Detail | What We Repair | Material |
|---|---|---|
| Exposed screws | Remove stripped screws and drive larger ones with new washers | Oversized screws, EPDM washers |
| Side and end laps | Clean old sealant, set new butyl, add stitch screws | Butyl tape and stitch screws |
| Rusted panels | Patch small holes; swap panels rusted through | Panels matched by rib profile and gauge |
| Skylight panels | Replace cracked panels and reseal the curb or laps | Matching translucent panels |
| Standing seams | Re-seam lifted runs and repair clips that let go | Seam tool and replacement clips |
Steel roofs last when the small details stay tight. Repairing them on time protects the panels themselves.
New washers seal each hole again, so rain stops running down the ribs.
Replacement panels lap correctly because they match the existing profile.
Closing laps keeps water from sitting in the overlaps where rust starts.
Panel swaps happen one at a time, so the building is closed in by day end.
Water that follows a rib usually starts at a screw or lap upslope. We trace the row and reset what failed.
Schedule Your Free InspectionMetal roof repair works row by row, so nothing upslope of the leak gets missed.
Each fastener row above the leak gets checked for screws that spin, stand proud, or have cracked washers.
Side and end laps near the drip get inspected for dried sealant, rust, and missing stitch screws.
Rusted-through panels are measured for rib profile, gauge, and length so the new ones lap correctly.
Bad panels come out one at a time, new butyl goes into every lap, and oversized screws close the holes.
Every repaired row and panel gets photographed, with notes on rust to watch elsewhere.
Metal buildings often carry flat sections, rooftop units, or plant equipment too.
A low-slope office wing beside a metal warehouse may need seam and drain repairs of its own.
Typical Repairs
When water shows far from any panel lap, leak tracing starts inside and follows the deck to the source.
Typical Repairs
Steel plant roofs with exhaust fans need curb repairs and walk pads around the equipment.
Typical RepairsAnswers about screws, laps, rust, and skylights on steel roofs.
Failed fasteners. Screws loosen as the panels move with temperature, and their rubber washers dry out and crack. Dried lap sealant, damaged flashing at curbs and walls, and rust holes follow. Freeze and thaw cycles speed all of it up, which is why we check the screw rows first.
Pull the stripped screw and drive a larger-diameter screw with a new sealing washer so it grips fresh metal. If the hole has rusted wider, a sealed metal patch goes over it first. Roofs with many failed screws get worked row by row so the next leak is not one row over.
When rust has made holes through the steel, when the panel flexes underfoot, or when rust covers most of the panel. Surface rust gets cleaned and treated instead. Replacement panels are matched by profile and gauge so they lap with the panels on each side.
Old sealant is cleaned out of the lap, stitch screws are tightened or replaced, and new butyl goes in where the panels overlap. Laps with movement get fabric and a compatible sealer over them. Standing-seam roofs with lifted panels get re-seamed and their clips repaired.
It can be either. Condensation forms on the underside of bare panels on cold mornings and drips without any rain, often in lines across the building. A leak follows rain and shows near a screw row, lap, or curb. We check the timing and the insulation before repairing anything.
Send the address and where the drips line up. We walk the screw rows and laps and price the repair.
