Commercial Metal Roof Coating
Exposed-fastener shop roofs get the full process: fastener pass, rust primer, fabric at laps, and the field coat.

As a McCordsville metal roof coating contractor, we coat exposed-fastener steel roofs on shops and warehouses, starting with a screw-by-screw fastener pass.

McCordsville metal roof coating jobs usually involve exposed-fastener roofs, where thousands of screws hold the panels and each one has a rubber washer that ages out.
Before any coating, we go row by row. Loose screws get tightened, stripped holes get a larger screw, and every cracked washer is replaced, so the coating seals a roof that holds still.
Exposed-fastener roofs fail in predictable places. These are the conditions we treat first.
Rubber washers harden and split after years of weather. Water tracks down the screw shank, so each one gets a fresh fastener and washer.
Rust forms in the dimple where water sits at each screw. Caught early, it cleans back to steel and takes primer.
Ridge caps lift when their screws loosen, and snow blows in under them. We refasten the caps and replace shrunken closures.
Wind catches the panel edges at the eave and lifts the side laps. Stitch screws and fabric close them up.
Water dripping in a straight line inside follows a purlin from a failed screw row. Those screws get replaced before anything else.
Loose eave trim lets wind under the panel ends and lifts the first screw row. We refasten the trim and close the gap with sealant.
Most McCordsville shop roofs take the metal coating process, with other systems for the parts of the property that differ.

Exposed-fastener shop roofs get the full process: fastener pass, rust primer, fabric at laps, and the field coat.
Shallow roof sections where water holds near a lean-to or addition take silicone.

Pitched shop roofs with good drainage can finish in acrylic for a bright, lower-cost topcoat.

A warehouse with leaks at laps across the whole roof can take spray foam and a protective topcoat.

Shingled offices on the same lot get a breathable coating made for asphalt shingles.
A straight row of drips means a row of screws has failed. A roof walk finds the row, and the fix stays small if it happens before rust spreads.
For shops and warehouses with exposed fasteners, coating turns thousands of leak points into one sealed surface.
After the fastener pass, the coating covers every screw head and washer under one film, so the next round of washer failures stays sealed under the coat.
Primer and coating keep water off the steel around each screw hole, where corrosion starts.
Light coating colors reflect sun that bare or faded panels absorb, keeping the work floor cooler.
Crews coat from the roof surface, so shop doors, vehicles, and equipment stay in use.
The fastener pass makes this order matter more than usual.
We walk each screw row, mark loose and stripped fasteners, photograph rust, and check the purlins from inside for drip lines.
Loose screws are driven down, stripped holes get oversized screws, and every cracked washer is replaced before any other work starts.
A pressure wash removes chalk and grime. Rust rings at screws are ground back and primed, and laps get fabric and mastic.
Base and top coats go on at the data sheet rate, with extra attention over screw heads where film can run thin.
McCordsville is one of six places we coat roofs. The other towns are below; if your building sits outside them, call us or send us a message.
Light industrial and flex buildings with several tenants under one roof.
Agricultural buildings, shops, and storage roofs.
Retail, church, and storage buildings.
Commercial, industrial, and farm roofs.
We do, for shops, warehouses, and other commercial buildings. Many roofs here have exposed fasteners and surface rust, which coat well after prep. We confirm the panels and purlins are intact before recommending a system.
For a shingled office on a McCordsville lot, the right product is a coating made for asphalt shingles, which breathes and bonds to granules. Metal roof coatings are not used on shingles.
Our Noblesville base is a short drive from McCordsville, so roof walks and job days fit easily into the schedule. Call or use the ballpark form to start.
Call us or send the roof size through the ballpark form. We follow up to set a roof walk, then send photos and a written scope.
Screws that were upsized before can go up one more size or get a stitch screw beside them. Each fastener has to hold tight before coating, so we test every one during the fastener pass.
