Flat Roof Repair
Flat roofs over offices and additions get drain, seam, and wall flashing repairs in matching membrane, often on the same visit as the steel roof next to them.
Flat Roof Repair detailsAs a Madison commercial roof repair contractor, we replace worn fasteners, reseal laps and ridge caps, and fix flat office sections on metal buildings.


Madison commercial roof repair work centers on steel: equipment shops, storage buildings, and offices with exposed-fastener roofs. Those roofs leak in a predictable order, starting at the screws, then the laps, then the ridge cap and the flashing around pipes.
Many of these buildings also carry a flat roof over an office or an addition. We repair both on the same visit, matching new panels to the existing rib and new membrane to the sheet already on the flat section.
Steel buildings around Madison often run two or three decades between roofs, so a well-kept fastener schedule matters more than any single repair. Rows that get new screws now keep the panels from rusting through later.
Metal buildings in and around Madison show the same five weak spots.
Washers crack and screws back out as the steel moves through hot days and cold nights. Rust trails below the heads mark the leaks.
Sealant at panel end laps dries and gaps. Wind-driven rain then wicks along the lap and drips onto the floor below.
Old foam closures shrink and caps work loose, so snow and rain blow in at the top of the roof.
Water that sits on a panel near a gutter or curb rusts it through first. Those panels get cut out and replaced.
Membrane over an attached office meets the steel wall at a flashing joint, a common spot for leaks.

Steel shops lead the list in Madison, but all four repair services are available.

Flat roofs over offices and additions get drain, seam, and wall flashing repairs in matching membrane, often on the same visit as the steel roof next to them.
Flat Roof Repair details
Exposed-fastener shop roofs get screw, lap, ridge cap, and panel repairs in the original rib profile.
Commercial Metal Roof Repair details
Drips onto tractors, tools, and stored equipment get traced along the purlins to the screw or lap letting water in, then sealed.
Commercial Roof Leak Repair details
Processing and fabrication roofs get curb, fan, and vibration repairs scheduled with the plant.
Industrial Roof Repair detailsCall us. Rust trails below screw heads mark leaking fasteners, and a row-by-row replacement stops them before the panels rust through.
Five steps, working across the roof one panel row at a time.

Rust on purlins and stains on the floor show which bays leak. We mark them before going up.
Every fastener row gets checked from eave to ridge, and worn or loose screws are marked for replacement.
Worn screws come out, fresh gasketed fasteners go in, and stripped holes get oversized screws.
Laps are scraped, sealed, and covered with fabric, and ridge caps go back on over new closures.
Panels rusted through are replaced with matching steel, sealed at both laps, and fastened tight.
Along with Madison, we repair commercial roofs in Norfolk and three nearby towns.

Storefront and office roofs where small seam and drain leaks get caught before the insulation soaks.
Roof checks after hail and wind for membrane punctures, torn flashing, and lifted panels.
Repairs after winter to ice-opened seams, crushed gutters, and bent edge metal.
Answers for metal shops and ag buildings in Madison.
Fastener replacement, lap sealing, and flashing repair cover most of them, since those are the first leak points on exposed-fastener roofs. Panels rusted through get replaced with the same rib. Flat sections over offices or additions get membrane and drain repairs. One inspection covers the whole building, steel and flat.
Shop work keeps going during most metal roof repairs, which run from the roof side. Crews stage lifts and panels away from overhead doors and set the day around deliveries. Panel swaps over equipment get a short window when the bay below can be cleared.
Yes. We serve Madison from Norfolk and repair roofs on shops, ag buildings, and offices in town. The inspection and pricing work the same as in Norfolk, with photos and a written price for each problem.
Most can. We measure the rib spacing, height, and gauge of the existing panel and order steel to match. When a profile has been discontinued, a close match with sealed laps or a short transition piece keeps the roof watertight.
That pattern often points to condensation rather than a leak. Warm, damp air inside meets cold steel and drips at sunrise. Rust on purlins and drips spread across a bay suggest condensation, while drips at one lap or screw suggest a leak. We check for both before recommending a repair.
One or two days covers most fastener and lap repairs on a shop roof, with the size of the building and the number of screw rows setting the pace. Panel swaps add time for ordering steel in the matching rib. We give you the plan and the number of roof days with the written price.
