Ashland Commercial Metal Roof Coating
We coat commercial metal roofs in Ashland: exposed-fastener R-panel and standing seam over warehouses, shops, and barns, with rust primed and every lap sealed first.
Rust graded before primer goes on
Oversized screws for stripped holes
Fabric over side laps and end laps
Base and top coats to thickness
Is This Roof A Fit?
The panels decide whether a metal roof can be coated. Four common cases on Ashland-area buildings show where each one starts.
- If Your Roof
Has Orange Haze On Firm Panels
Light surface rust on steel that flexes normally at mid-span is the classic candidate.
Start WithClean, Prime, Coat - If Your Roof
Has Flaking Scale And Pitting
Heavy scale gets ground or brushed back, then primed twice at the worst spots before the coat.
Start WithHeavy Prep, Then Coat - If Your Roof
Shows Chalky White Bloom
White rust on galvanized steel needs cleaning and a primer rated for galvanized metal.
Start WithGalvanized Primer - If Your Roof
Has Holes Along Laps And Gutters
Rust-through gets cut out and patched with new steel, and widespread rot means re-paneling.

Where Ashland Metal Roofs Start To Leak
Exposed-fastener roofs fail in predictable places. Here is what each one looks like from inside, and what we fix on the roof.
Washers Cracked By Sun
Inside The BuildingSmall drips appear at evenly spaced points along a purlin line, often days after the rain stops.
On The RoofSun-dried rubber washers have split around the screw shank. We back out stripped screws, drive oversized replacements, and dab each head before the field coat.
End Laps Opening Midslope
Inside The BuildingA stain shows up across the full width of one panel, partway between eave and ridge.
On The RoofThe end lap, where one panel overlaps the next one downslope, has lost its sealant. It is cleaned and bridged with fabric or compatible seam tape.
Ridge Cap Joints Lifting
Inside The BuildingWater runs down the inside face of the ridge line during wind-driven rain.
On The RoofRidge cap and hip trim joints have loosened. Trim is refastened first, then the joints are sealed so the coat covers a tight edge.
Skylight Panel Edges Failing
Inside The BuildingYellowed light panels drip at their edges, and stock below them stays wet.
On The RoofEdges around skylight panels have pulled away from the metal ribs. We seal the perimeter, and cracked panels are flagged for replacement.
Gutter Seams Rusting Through
Inside The BuildingRainwater pours behind the gutter and down the wall at the corners of the building.
On The RoofGutter seams and corner joints have rusted open. Leaves come out first, seams and end caps are resealed, and rusted-through sections are patched.
Commercial Roof Coating Options for Ashland
Metal roofs around Ashland take one of three coating systems. Slope, standing water, and the need for insulation decide which one fits.
Acrylic Over Primed Steel
Steep R-panel roofs that shed water fast suit a white acrylic system over rust primer. It recoats easily later and holds its brightness because rain rinses dirt away.

Silicone Where Water Lingers
Low-slope sections, dock additions, and panels behind rooftop units that hold water after storms take silicone, which resists standing water. Later recoats also need silicone.

Foam Plus Coating
Spray foam fills the ribs, buries the fasteners, and insulates the roof, with a coating over the foam for sun protection. It adds weight, so the structure is checked first.

Benefits of Coating Your Roof
Coating a solid metal roof keeps the panels you already paid for. These four gains hold when the steel and purlins are still sound.
Thousands Of Screw Heads Sealed
Each fastener is checked, tightened or replaced, and buried under two layers of coating, which ends the slow drips at washers.
Laps Reinforced With Fabric
Side laps and end laps move with every hot afternoon. Fabric set in coating bridges them with more material than any other spot on the roof.
Lower Cost Than Re-Paneling
Keeping solid panels in place avoids tear-off, disposal, and new steel. How much it saves comes down to how many panels need patching first.
A Cooler Steel Surface
A white topcoat reflects much of the summer sun that a faded panel absorbs, which eases the load on rooftop units below.
Rust Showing Through At The Laps?
Call with the roof type, its age, and where the rust shows. Rust at laps and gutters is the first thing we grade on an Ashland metal roof inspection.
Steps To Coat An Exposed-Fastener Roof
Metal roof coating jobs follow a fixed order, with most of the time spent on fasteners and laps.
Inspect Your Roof
On The RoofEach section is walked and pushed at mid-span. We count stripped screws, sort rust by type, and mark skylight panels, curbs, and gutter runs on a roof plan.
Confirm The Permit Path
PaperworkCoating over existing panels is a lighter scope, but panel replacement or new skylight panels inside Ashland goes to the city’s building inspection first.
Wash And Strip Loose Rust
On The RoofPressure washing takes off chalky paint and dirt. Flaking red rust is scraped or wire-brushed first, so primer lands on firm steel instead of powder.
Replace And Seal Fasteners
On The RoofStripped screws come out for oversized ones, loose screws are snugged until the washer seats flat, and every head gets a dab of sealant or brushed mastic.
Bridge Laps And Trim
On The RoofSide laps, end laps, ridge caps, and pipe boots get reinforcing fabric set in coating or compatible seam tape, the weakest lines on the roof first.
Prime And Coat The Field
On The RoofRust primer goes on the treated areas, then base and top coats go on at the specified thickness, burying the fastener heads a second time.
When Another Coating Fits Better
Some metal buildings need a different system on part of the roof. Each card says when.
Silicone Roof Coating
Flat additions and dock roofs that hold water call for silicone roof coating on those sections.
Acrylic Roof Coating
Steep R-panel that drains fast suits acrylic roof coating, which recoats easily.
Spray Foam Roofing
Buildings that sweat or bake inside gain insulation from spray foam over metal roofs.
Shingle Roof Coating
Shingled offices with metal canopies can get coating for commercial shingle roofs in the same visit.
Before You Coat A Metal Roof
Answers to what Ashland owners ask about rust, cost, and drainage on metal buildings.
- Panels And Rust
Which Metal Roofs Are Good Candidates?
Steel roofs with surface rust, loose or leaking fasteners, and tired paint make the best candidates, as long as the panels are solid. Push a panel at mid-span: normal flex and intact purlins mean the deck is ready for prep. Daylight through rust holes or sagging panels points toward re-paneling.
Can You Coat Over Rust?
Yes, once the loose scale is gone and a rust-inhibiting primer is on. Crews scrape or wire-brush flaking rust and pressure wash, so primer bonds to firm steel. Galvanized trim with white rust takes its own primer, and holes along laps are cut out and patched first.
- Cost
What Drives The Cost On A Metal Roof?
Roof size, rust level, fastener count, and the coating type matter most. A clean roof with light rust costs less per square foot than one with heavy scale and failed laps. Skylight panels, curbs, roof height, and any panel replacement at gutters or end laps add to the scope.
Do You Replace Every Screw?
Usually only the stripped, rusted, or backed-out ones. Sound screws are snugged so the washer seats flat without crushing, and every head is sealed before the field coat. On older roofs, the number of replacements is one of the main findings of the inspection.
- Drainage
Does The Ashland Floodwall Change Drainage Planning?
Inside the floodwall, roofs still rely on clear gutters, downspouts, and scuppers. The city’s Floodwall Division keeps over three miles of concrete wall, west-end levees, and six pump stations. When floodgates close during high water, blocked gutters overflow onto walls and entries, so we check drainage on every Ashland job.
Can Coating Fix Water Sitting On Low Panels?
Coating seals the surface and leaves the slope as it is. Where water sits behind a curb or near a gutter, those panels get silicone, which resists standing water, and clogged gutters get cleared. Building slope back into a flat area takes foam.
