Fit Check

Columbus Commercial Metal Roof Repair or New Panels?

Columbus commercial metal roof repair fits steel that still holds a screw. Panels that are rusted through across the roof call for a different plan.

Roof Conditions

Metal Roof Leaks on Columbus Commercial Buildings

Steel roofs leak at joints and fasteners far more often than through the panel itself. These conditions account for most of the metal roof calls we get.

Sun and Cold

Most Common Cause of Metal Roof Leaks

You See
Rust rings around screw heads and drips that line up with a purlin.
What It Means
The rubber washer is the only seal at each screw. Sun and cold harden it, and panel movement widens the hole.

Movement

Metal Roof Seam Repair at End Laps

You See
Daylight or rust streaks where two panels overlap mid-slope.
What It Means
Long runs grow and shrink with temperature. Lap sealant cracks and the stitch screws loosen with each cycle.

Rust

Rusted Metal Roof Panel Replacement

You See
Flaking steel and pinholes near the eave or under a dripping unit.
What It Means
Rust that has gone through the steel will not hold a screw. That section of panel has to come out.

Equipment

Cracked Pipe Boots and Curbs

You See
A drip at a vent stack or a stain beside a rooftop unit curb.
What It Means
Boots split from sun and movement. Curb flashing set without room to move tears where it meets the ribs.

Wind

Loose Trim and Ridge Closures

You See
Rattling ridge cap, bent rake trim, or birds getting in at the eave.
What It Means
Missing closures let wind-driven rain and snow past the ridge and eave, often far from the visible damage.

Why Repair

Benefits of Commercial Metal Roof Repair for Columbus Owners

A steel roof with solid panels can keep working for a long time once the joints are tight again.

Panels Stay Put

Most of the steel on an aging roof is still good. Replacing washers and lap sealant keeps those panels in service.

Rust Stops Spreading

Water sitting at a leaking screw rusts the panel and the purlin under it. Sealing the hole stops that cycle.

Dry Goods and Equipment

Warehouses and ag shops store things a drip can ruin. A tight screw line keeps water off pallets and machines.

Repairs That Match

New panels match the old profile and gauge, so laps close properly and the roof drains the way it was built to.

Repair Steps

How a Metal Roof Repair Gets Done

We work row by row, lap by lap, so nothing on the roof gets skipped.

  1. 1

    Survey

    Walk Every Panel Run

    Each screw line, end lap, and piece of trim gets checked. Problem spots are marked on the roof and photographed.

  2. 2

    Inside

    Match Drips to Purlins

    Stains and rust on the purlins below show which screw lines and laps are leaking now and which are close.

  3. 3

    Fasten

    Replace Worn Screws

    Old screws come out and new ones with fresh washers go in. Stripped holes take an oversized screw into solid steel.

  4. 4

    Seal

    Rebuild Laps and Boots

    End laps get new butyl and stitch screws. Cracked pipe boots and loose curb flashing are replaced.

  5. 5

    Swap

    Replace Rusted Panels

    Panels with holes or soft steel are cut out and replaced with matching profile and gauge, sealed at both laps.

Metal Roof Questions

Commercial Metal Roof Repair Questions for Columbus Warehouses

What owners of steel buildings ask us before a repair.

What causes most metal roof leaks?

Worn screw washers

Fasteners. Each screw seals with a small rubber washer, and sun and cold harden that washer within a few years. Panel movement then works the hole larger. End laps, trim, and pipe boots are the next places we look, row by row.

How to fix leaking screw holes in a metal roof?

New screw, new washer

Pull the old screw and drive a new fastener with a fresh washer. A hole that has stripped takes an oversized screw into solid metal. Holes left from removed equipment get sealed and covered with a metal patch, and each repaired screw head gets sealant over the washer.

When do rusted panels need replacement instead of treatment?

Holes or soft steel

Surface rust gets cleaned and treated. Rust that has made holes, flaking layers, or soft spots that will not hold a screw means that panel comes out. New panels match the profile and gauge so the laps close and seal properly.

How are seams repaired on farm supply warehouses?

Clean, tape, refasten

Old sealant is cleaned out of the lap, new butyl tape goes in where the lap can be opened, and the lap is refastened. Exposed seams that cannot be opened get reinforcing fabric and sealant on top. On long warehouse runs we check every lap from eave to ridge.

How are penetrations repaired on manufacturing plant metal roofs?

Boots, curbs, diverters

Cracked pipe boots get replaced with boots sized to the pipe, and curb flashing is rebuilt so the steel can still move. Where water stacks against the uphill side of a curb, a diverter sends it around. Every vent and conduit on the roof gets checked.
