Screw Rows
Washers dry out and screws back out as panels expand in summer and shrink in winter. Each loose screw leaves a small hole at the top of a rib.

Is Terre Haute Commercial Metal Roof Repair Enough?
Terre Haute commercial metal roof repair holds when the steel and framing are solid. These signs sort a repair from a new metal roof.
A Repair Fits When
- Leaks line up with screw rows or end laps
- Rust stays on the surface and the steel feels solid
- Only a few panels show holes or soft spots
- Purlins under the leak are straight and dry
- Ridge caps and trim are loose but intact
Look At Replacement When
- Rust has holed panels across the roof
- Panels flex or dent under a careful step
- Purlins show rust scale or bending
- Water drips at many laps after every rain
- Old coatings peel in sheets off most panels
Commercial Metal Roof Repair Zones on Terre Haute Buildings
Metal roofs leak where panels meet, where screws pass through, and where trim closes the edges. We check these five zones first.
Side and End Laps
Sealant between overlapping panels ages and lets go. End laps on a long run take the most water and leak first.
Ridge and Eave Trim
Closures under ridge caps and eave trim shift or go missing, letting wind-driven rain and snow blow in at the ends of the ribs.
Skylight Panels
Plastic panels crack and yellow with sun, and their laps rarely match the steel next to them. Many shop leaks start here.
Panel Faces
Surface rust spreads where paint has worn through, then thins the steel. A probe tells us whether a rusty panel is still solid.
Commercial Metal Roof Repair Methods in Terre Haute
Repairs match the panel profile and gauge already on the roof, so new parts lap and seal like the old ones.
Leaking Screw Holes
Worn screws come out and new or oversized fasteners go in with fresh sealing washers. Stripped holes get a larger screw or a sealed patch.
Metal Roof Seam Repair
Laps are cleaned, tightened with stitch screws, and sealed with butyl tape, mastic, or reinforced seam fabric. Standing seams get re-crimped.
Rusted Metal Roof Panel Replacement
A holed panel comes off, the purlin below gets checked, and a matching panel goes on with sealed laps on both sides.
Rust Treatment on Nearby Panels
Light rust next to a repair is wire-brushed and primed during the same visit so it stops spreading toward the new steel.

Drips Lining Up With the Screw Rows?
A row of drips under the ribs points to worn washers or backed-out screws. Call and tell us where they line up.
How Terre Haute Commercial Metal Roof Repair Gets Done
A metal roof repair runs in five steps, ending with the laps checked by water.
Walk The Ribs
Screw rows, laps, ridge caps, and skylight panels near the leak get checked from the roof, panel by panel.
Check The Purlins
From inside, the framing under the leak is checked for rust scale or bending before any panel comes off.
Replace Fasteners
Worn screws and washers on the leaking rows are swapped, with larger screws where holes have stripped.
Seal Or Swap Panels
Laps get stitched and sealed, and panels with holes are replaced with matching steel.
Water-Test The Laps
A hose run over the repaired laps and screw rows confirms they stay dry inside.
Other Repairs Near Metal Roofs in Terre Haute
Steel buildings often carry a low-slope section, rooftop units, or a leak that hides behind insulation.
Flat Roof Repair
Office wings and loading areas on metal buildings often have a low-slope membrane that leaks at its own seams.

Commercial Roof Leak Repair
Faced insulation under a metal roof hides where water enters, so tracing comes first on those leaks.

Industrial Roof Repair
Plants with metal roofs carry exhaust fans and curbs that need flashing work planned around production.

Answers on screws, seams, rust, and whether a metal roof can be saved.
Screws And Seams
How to fix leaking screw holes in a metal roof without new panels?
Replace the worn screws with new or oversized fasteners and fresh washers. Where a whole run is failing, every screw on that run gets replaced so the repair holds through summer heat and winter cold.
What does metal roof seam repair include?
Cleaning the lap, tightening or adding stitch screws, and sealing it with butyl tape, mastic, or reinforced fabric. End laps and ridge seams take the same treatment because water works in there first.
Rust And Panels
When does rusted metal roof panel replacement make sense?
When rust has eaten through the steel, the panel has lost strength at a lap or purlin, or holes keep opening. Light surface rust gets cleaned and primed, and the panel stays.
Can a metal roof be repaired if it is old?
Age alone decides little. If the panels and framing are solid, fasteners, laps, trim, and single panels can all be repaired. Rust holes across the roof or damaged framing point to new panels.
Do new screws fit the old holes?
Oversized screws grip holes that have stripped or rusted wider, and their larger washers cover the worn ring around the hole. Badly torn holes get a small sealed patch first.
Winter
Why do metal roofs leak more in winter?
Cold shrinks the panels and opens worn laps, and snow sits against ridge caps and end laps for days. Meltwater then finds every loose screw and gap that summer rain missed.
Should snow be cleared off a metal roof to stop leaks?
Clearing does little for leaks on its own. Sealing end laps and ridge closures before winter does more, since drifts only leak where an opening already exists. Heavy snow load is a separate question for a structural engineer.
