Commercial Metal Roof Coating

Our main service for steel roofs: rust removal, primer, new or reset fasteners, sealed laps, and a coating system across the whole field. It is the service most Allentown warehouse and plant roofs start with.

  • Exposed-fastener warehouse panels
  • Standing-seam roofs with tired finish

  • Rust depth at laps and cut edges
  • Purlin attachment

Silicone Roof Coating

Silicone suits low slopes and slow-draining roofs. It goes on in one heavy pass and must be recoated with silicone later. Drains and wet spots get fixed before the silicone pass.

Best For
  • Low-slope metal and membrane
  • Roofs with slow runoff
Check First
  • Why water stands
  • Bleed-through from old asphalt

Acrylic Roof Coating

Acrylic is water-based, bright white, and easy to recoat. It needs dry, mild days, so its season here runs from late spring into early fall. Low spots on the roof get a different detail so acrylic stays dry between storms.

Best For
  • Pitched metal with good runoff
  • Reflective finish goals
Check First
  • Ponding spots
  • Forecast for dew and rain

Spray Foam Roofing

Spray foam builds a continuous, insulated layer over metal or older flat roofs, then gets a protective topcoat. It adds insulation where cold steel or heat gain is a complaint inside the building.

Best For
  • Plants wanting added insulation
  • Roofs with many transitions
Check First
  • Panel attachment
  • Air intakes and overspray zones

Shingle Roof Coating

Shingle coating fits a narrow set of roofs: flat, attached, dry shingles with a coating made for asphalt. Curling, brittle shingles are steered toward replacement instead.

Best For
  • Mansard faces on commercial blocks
  • Shingles with granules intact
Check First
  • Curl and brittleness
  • Flashing condition

How Every Coating System Gets Chosen

One sequence applies to all five services, from the first ladder up to the last coat.

Get A Free Estimate
  1. 1

    Inspect Your Roof

    A full walk of the panels or membrane, the seams, the drains, and every curb, with moisture checks where the deck or insulation looks suspect. Findings are written up section by section for the owner.

  2. 2

    Repair What Fails

    Rotted panels, loose fasteners, split flashing, and wet foam come out or get fixed. Coating goes over repaired details only. Each repair is listed and priced on its own line.

  3. 3

    Match The System

    Slope, drainage, existing finish, and the recoat plan narrow the choice between silicone, acrylic, foam, or a shingle product. The chosen system is named with its recoat path.

  4. 4

    Prepare And Coat

    Cleaning, primer where the product calls for it, reinforced details, then coats applied to the specified thickness and checked. Weather decides the coating days, with the roof surface dry and dew-free.

  5. 5

    Check And Hand Over

    Thickness gets checked at ribs, laps, and details, and the owner receives a written summary of the repairs made and the system applied.

Questions About Our Coating Services

Choosing

Which metal roof coating service fits my building?

The roof decides. Ribbed steel with rust and leaking screws points to metal roof coating. Low slopes that drain slowly lean toward silicone. Pitched panels with good runoff suit acrylic. Foam fits when insulation matters, and shingle coating fits only shingles still in good shape.

Can two systems be used on one building?

Yes. A plant with a pitched metal shed and a flat office section can carry acrylic on the panels and silicone on the flat area, with a planned transition detail between them so each can be recoated with its own product later.

Prep

Why does every service start with repairs?

Coatings seal surfaces. They do not hold down a loose panel, dry out wet insulation, or close a rusted hole. Repairing those first is what lets the coating do its job across the whole roof.

Do coatings need primer on metal?

Often, yes. Rust-inhibiting primer goes on cleaned spots, and some products call for a primer over galvanized or painted steel for adhesion. The manufacturer sheet decides, and we follow it for the product chosen.

Scheduling

When is coating season in the Lehigh Valley?

Most coating work runs from late spring through early fall, when surfaces stay dry and nights stay mild. Silicone tolerates cooler, damper days than acrylic. Repairs and inspections can happen almost any time of year.

Cost And Upkeep

What do coating services cost per square foot?

For planning, coating runs about $2.50 to $4.00 per square foot and replacement about $5 to $8. Roof size, access, rust and seam prep, fastener sealing, coating type and thickness, coats, and penetrations move the final figure.

How often does a coated roof need attention?

Plan on an inspection each year and after major storms. Walk paths, curbs, and drains get the closest look, since wear and damage show up there first.

Can different services be priced together?

Yes. A building with metal panels, a flat section, and a shingle mansard gets one inspection and one estimate that lists each system separately.

Do you check for wet insulation on every roof?

Moisture checks are part of every inspection. Soft spots, stained deck, and sagging facing get probed, and wet areas are cut open to confirm before any coating is planned over them.

Do you remove old coatings before applying new ones?

Only where they fail adhesion tests or are incompatible with the new product. Coatings that are well bonded and compatible are cleaned and recoated.
