Erie commercial metal roof coating begins at the fasteners. We replace and seal failed screws, close the laps, prime rust, and coat the panels.
Erie commercial metal roof coating suits panels that are still attached and mostly dry. The raised column shows that roof; the others need more first.
These are the details we fix on metal roofs before any coating. Each one is a place water gets in.
Thousands of screws hold an exposed-fastener roof, and each washer ages. We replace stripped screws with oversized ones, then seal every head so the coating bridges sealed fasteners.
A loose screw sealed in place keeps moving under the coating and splits it within a season. Connections are tightened or replaced first, and only then capped with sealant.
Hail-marked panels get checked at seams, fasteners, and flashing as well as the field. Cosmetic dents can be coated over; cracked seams and loosened screws are repaired before the coating.
Ice and slow meltwater keep the low edge wet longest. That edge is brushed, primed with a rust-inhibiting primer, and given a heavier coat than the field.
End laps and ridge closures loosen as panels expand and contract. We stitch and seal them so wind-driven snow and rain stop finding a path in.
Curbs under fans and units on rail and plastics plants often leak at their corners. Their flashing is rebuilt so the coating ties into a sealed base.
These are the coating approaches we use on commercial metal roofs in Erie and how they differ.
| Option | Where It Fits | What To Know |
|---|---|---|
| Acrylic metal coating system | Sloped panels with good runoff | Needs warm, dry days to cure |
| Silicone over metal | Low-slope metal with slow drainage | Later repairs need silicone |
| Rust-inhibiting primer plus topcoat | Panels with scattered surface rust | Primer chosen for the steel and coating |
| Seam and fastener program only | Sound panels with leaks at details | Leaves the field uncoated for now |
Coating a repaired metal roof helps three groups in the building, each in its own way.
Call and tell us what you see on the panels. We will walk the roof and mark every failed fastener before talking about coating.
Each roof follows these five steps, with repairs ahead of the first coat.
We check each screw, washer, and support, every lap and ridge cap, and the flashing at curbs and walls. Inside, we look for the drip lines that show where water enters.
Stripped and backed-out screws come out and larger ones go in. Laps that lifted are stitched down, and panels rusted through are replaced with matching metal.
Panels are washed clean of dirt, chalk, and oil. Rusted areas are brushed to firm steel, then primed with a product matched to the coating.
Every screw head is capped, and laps, ridges, and penetrations get reinforced seam treatment. These details get their own pass ahead of the field coat.
Coats go on at the thickness the product sheet specifies, inside its temperature range. We measure as we work and finish edges by hand.
Some roofs fit another system better. These are the other four we install.
Thick silicone for low-slope roofs where water lingers.
Water-based coats for sloped panels in warm, dry weather.
Insulating foam and topcoat over a dry, repaired deck.
Coating flat, attached commercial shingles both makers approve.
Plan on about $2.50 to $4.00 per square foot of roof for coating, against about $5 to $8 for replacement. On a plastics plant, the equipment layout moves the price: more curbs, piping, and service paths mean more detail work, even when two roofs share the same area.
A sealant cap over a loose screw hides movement without restoring attachment. We check each screw, washer, and support to find what has failed, fix the connection, and then seal it, so the coated roof rests on fasteners that hold.
Yes. After hail we separate impact damage from cosmetic dents by checking seams, fasteners, and flashing along with the panel field. Any metal repairs are done before preparation for coating starts.
Check how well the old coating still bonds, how much protection is left, and what shape the steel is in. We separate cleaning and renewal from panel or flashing repairs, so new coating goes over a roof that can stay in service.
Most systems call for a base coat and a topcoat, with extra material at seams, screws, and gutter lines. The product sheet sets the thickness, and we measure it during application.
Coating seals the outside of the panels; it leaves indoor moisture alone. If drips trace to condensation on the underside, ventilation or insulation changes are the fix, and we tell you which drips are which before quoting.
