Will a Repair Hold on This Metal Roof?
Steel that is still firm takes repairs well. A Lexington commercial metal roof repair contractor checks four things before choosing the fix.
If Your Roof
Drips Under Panel Overlaps in Heavy Rain
End laps get wire-brushed, sealed, stitch-screwed, and covered with reinforced tape bedded in sealant.
Start WithLap Repair
If Your Roof
Shows Rust Through in Spots Along the Gutter Line
Pinholes get primed and patched, and rusted-through eave panels get replaced with sheets of the same profile.

If Your Roof
Sits on Rusted Purlins or Has Panels Failing Across the Field
Structure under the panels comes first, and widespread rust-through points to replacement planning.

Metal Roof Leaks You Notice Inside and Out
Metal buildings move water along purlins and panel ribs, so the clue inside often sits downhill of the cause.
Backed-Out Screws
Inside The Building
Drops land in a tidy line along a purlin, usually after windy storms.
On The Roof
Screw heads stand proud of the panel, and their washers have dried and split.
Open End Lap
Inside The Building
Water shows up mid-slope during heavy rain and stops when the rain eases.
On The Roof
The upper panel's lap has opened, and rain backs up under it from the panel below.
Rusted Eave Panels
Inside The Building
Orange staining runs down the inside of the eave wall.
On The Roof
Pinholes and flaking rust sit along the lowest panel edge and the gutter line.
Cracked Skylight Panel
Inside The Building
Light and water come through one corner of the translucent sheet.
On The Roof
The skylight panel has yellowed, cracked, or lost its seal at the side laps.
Commercial Metal Roof Repair Options for Lexington
Most metal roof leaks come from four places, and each gets its own fix.
Metal Roof Screw Leak Repair
Backed-out or stripped screws come out along each panel run, and the next larger diameter goes in so the threads bite fresh steel. Each head gets a new EPDM washer and a sealant cap.
Repairing Leaking End Laps on Metal Roofs
Rust along the lap gets wire-brushed, stitch screws close the gap, sealant goes into the lap edge, and reinforced tape bedded in sealant covers the joint.
Rusted Metal Roof Panel Replacement in Lexington
Through-rusted or crushed panels get swapped for new sheets after the crew measures rib spacing and height, and the purlin underneath gets checked before new screws go in.
Metal Roof Skylight and Ridge Cap Repair
Ridge caps get new foam closures and resealed fasteners. Cracked or yellowed skylight sheets get replaced with matching translucent panels, with screens over broken ones until then.
Panels Stay on the Building
Upsizing fasteners and sealing laps keeps solid steel in service. Swapping only the rusted eave panels and gutters, where rust starts first, leaves the rest of the roof working as it was.
- Fewer new panels to order
- Original profile kept on the building
- Gutters and eaves fixed where rust starts
Benefits of Repairing Your Roof
Steel that still holds a screw is worth keeping on the building.
Screws That Bite Again
Oversized screws reach fresh steel in old holes, and new washers seal each one.
Leaks Stop at the Lap
Sealed and taped end laps keep heavy rain from backing up under the upper panel.
Buildings Stay in Use
Barns, shops, and warehouses keep working, with the crew on the roof while the floor below stays in use.
Water Dripping in a Line Under the Purlins?
A straight line of drips usually means failed washers along one panel run. Call us and we will check that run end to end.
Call UsSteps a Lexington Commercial Metal Roof Repair Contractor Follows
Metal repairs follow the water downhill, then work back up to the cause.
- WALK
Inspect Your Roof
We walk each panel run above the leak, checking screw heads, end laps, ridge caps, skylights, and the eave line where rust starts.
- PURLIN
Check the Structure
Rusty screw holes get a look at the purlin beneath, because new fasteners need solid steel to grip.
- FASTEN
Swap the Fasteners
Stripped and backed-out screws come out, and oversized screws with new EPDM washers go back in along the whole run.
- SEAL
Seal and Tape Laps
Laps get cleaned of oil and rust, sealed with butyl or urethane, and covered with reinforced tape where water backs up.
- MATCH
Replace What Rusted Through
Panels or gutter sections past repair get replaced with the same profile, then photos of every repair come to you.
More Ways We Fix Commercial Roofs
Metal buildings often have a membrane office roof, a hidden leak, or plant equipment overhead.
Flat Roof Repair
Membrane sections beside a metal building get seam, curb, and drain repairs with welded or taped material.
Typical Repairs
- Transition flashing at the metal edge
- Curb flashing on low-slope units
- Cleared drains and scuppers
Commercial Roof Leak Repair
Water running along purlins can surface far from the bad lap, so tracing starts at the drip and works uphill.
Typical Repairs
- Drip marked on the floor plan
- Hose tests up the slope
- Ridge vents checked for wind-driven rain
Industrial Roof Repair
Plant buildings with acidic or hot exhaust get corroded panels, fasteners, and membrane around vents repaired.
Typical Repairs
- Corroded fasteners near discharge
- Vent stacks extended where heat is the cause
- Lockouts set with plant safety staff
Top Commercial Metal Roof Repair Questions in Lexington
Fasteners, laps, rust, and trim cause most metal roof calls.
Why Do Screws on a Metal Roof Leak, and How Are They Fixed?
Rubber washers dry out and crack, and panel movement loosens screws in their holes. The fix is the next larger screw diameter so the threads grab fresh steel, with a new washer under each head and sealant or a cap over it.
A leak along one straight row of screws, especially at the eave, points to fasteners more than panel damage.
How Are Leaking End Laps and Side Laps Repaired on Metal Roofs?
Clean the joint, seal it with butyl or urethane, add stitch screws where it has opened, and cover it with reinforced tape or fabric. End laps leak more on low-slope metal because heavy rain backs up under the upper panel.
Side laps get the same treatment wherever wind-driven rain shows up along the ribs.
When Does a Rusted Metal Roof Panel Need Replacing Instead of Repair?
Surface rust on firm steel gets wire-brushed, primed, and sealed, and pinholes in a small area get a sealed metal or fabric patch. Wide rust-through, or a crushed or torn panel, calls for a new sheet of the same profile and a check of the purlin under it.
Gutters and eave panels rust first and deserve the closest look.
How Do Metal Roof Repairs Differ From Membrane Roof Repairs?
Metal repairs center on fasteners, laps, and rust, while membrane repairs center on seams, flashing, and punctures. Metal hides damage in rusted purlins and moves with heat that works screws loose, and membrane hides wet insulation and shrinks at seams and corners.
Mixing materials causes trouble. Silicone caulk on a metal lap or asphalt cement on a TPO seam blocks the bond of the permanent repair.
What Gets Fixed at Ridge Caps, Flashing, Skylights, and Gutters on a Metal Roof?
Ridge caps get new foam closures, resealed fasteners, and taped laps. Wall and curb flashing gets refastened, resealed, and tucked under counterflashing, and cracked skylight panels get matching translucent sheets sealed at every lap.
Gutters get cleared, resealed at seams and end caps, and rehung to pitch. Rusted-through gutter sections are replaced outright.
