As a Hammond commercial metal roof repair contractor, we replace worn screws, reseal laps and ridge caps, and swap rusted panels on shops, warehouses, and mill buildings.
Hammond commercial metal roof repair fits panels that are still attached and solid at the purlins. The raised column is that repair; the others show the bigger jobs.
Metal roofs move every day as the steel heats and cools. That movement works open the same five places on nearly every building.
Rubber washers dry out and crack, and screws back out as panels move. Water seeps in at each hole along the whole row.
Laps lose their sealant and open a gap at every rib. Wind pushes rain sideways into them during storms off the lake.
Ridge, eave, and rake trim hold the roof edges. Freeze-thaw cycles pull their fasteners loose and lift the closures.
Clear panels turn brittle and crack under hail or foot traffic, and their laps with the steel panels open up.
Rust starts where water sits: eaves, laps, and around penetrations. Once it eats through, patches stop holding and a new panel goes in.
Leaking screws come out and new ones with fresh washers go in. Stripped holes get a slightly larger screw, and badly enlarged ones get a sealed patch first.
Old sealant is scraped out, the steel is cleaned, and butyl tape or sealant goes back in before the lap is stitched tight again.
Panels rusted through are unscrewed and replaced with the same profile, so the ribs nest and the laps seal with the panels beside them.
Loose or rusted ridge caps, wall flashing, and curb trim come off. New pieces are set in butyl tape and fastened at the right spacing.
Metal repairs are mostly hardware and sealant, done in the right order. These four cover most of what we do.
Long metal warehouses along the rail lines show the same wear from end to end. These are the changes a repair makes.
A row of drips points to a row of tired washers. Call us, and we check every fastener along that run.
(219) 389-4915Call UsMetal roofs get checked from inside and from the top, since water travels along purlins before it drops.
Inside, we look for daylight at laps, rust streaks on purlins, and drip marks on the floor. Those point to the screw rows and laps to check up top.
Each fastener line near the leak gets checked by hand for backed-out screws and cracked washers, along with laps, trim, and skylights.
Rusted panels are swapped first, then laps are resealed, then fasteners and trim are replaced, so each step seals against new material.
Photos show each run, lap, and panel we worked on, with notes on the rows that will need attention next.
Many metal buildings here connect to flat sections or plant equipment. These repairs pick up where the panels end.
Office additions and low wings on metal buildings often carry a flat roof. Its drains and seams need a different repair than the panels next door.
Repair Includes
A drip near a metal wall can come from a gutter, a parapet, or a lap two bays away. A leak trace finds which one before anything is replaced.
Repair Includes
Metal plant roofs carry exhaust fans and curbs that vibrate all day. Industrial repairs rebuild that flashing and protect the floor below while we work.
Repair IncludesEach row leads with the short answer. Open it for the full detail on metal roofs.
Loose or rusted flashing comes off, the panels under it get cleaned, and new flashing goes on in butyl tape, fastened at the correct spacing. Ridge caps, wall transitions, curbs, and pipe boots are the usual spots. Freeze-thaw movement loosens nearby flashing too, so we check it on the same visit.
Dents are mostly cosmetic. The water comes through punctures, split seams, cracked washers, broken sealant, and damaged ridge caps or skylights. We replace the damaged fasteners, reseal the seams, swap punctured panels or skylight panels, and photograph everything for the insurance claim.
Failed fasteners top the list. Washers dry and crack, and screws back out as the panels expand and contract with the weather, so water seeps in at every hole. Open side laps, rusted panel edges, and loose flashing follow close behind, and we check all of them on each repair.
Out comes the leaking screw, and in goes a slightly larger replacement with a new washer if the hole is stripped. Badly enlarged holes get a sealed patch first. Neighboring screws share the same worn washers, so replacing the whole run beats chasing one hole at a time.
Summer sun bakes sealant dry and drives daily expansion at seams, flashing, and screws, and dark roofs run far hotter than the air. On metal buildings the damage shows as cracked caulk and loose fasteners along the hottest slopes, which we reseal or replace.
Send the address and where the drips line up inside. We check the screw rows, laps, and trim above them and price the repair.
