Clean Panels Without Scratches or Leaks
Metal roofs look tough, but the paint and the seams are not. High pressure can scratch the finish and push water past seams and screws. We use a soft wash and a gentle rinse to remove algae, mildew, pollen and salt film, so nothing gets forced where it should not go.
This service is part of our roof cleaning work and our broader Wilmington exterior cleaning services.
Beach cottages and farm buildings collect the most buildup. While we are up there, we also look at fasteners and point out any that are rusty. Send a snapshot of the roof and the range is on its way.
What Is Included in a Metal Roof Visit
A visit covers the pieces that make up the whole roof system.
- PanelsStanding seam or screw down, washed in the direction of the ribs.
- Ridge caps and trimWhere dirt and salt gather.
- GuttersRinsed so run off does not stain below.
- Fasteners and seamsChecked, with photos of anything that looks rusty.
- Plants belowSoaked before and after.
Salt Air, Humidity and Metal Roofs
Salt air at the beaches leaves a film, and humidity inland grows algae. The two attack metal in different ways, and our coast gets plenty of both. The National Weather Service puts average humidity near 74 percent.
Storms add to it. Cape Fear averages a hurricane with 74 mph or higher winds about every six years, and each one leaves salt, mud and debris on rooftops. Metal is common on beach cottages and on farm buildings north of the city, so we see all of it.
Five Steps From Hazy Metal to Clean Metal
Every roof gets the same careful order, with small changes by panel type.
- Look at the seamsWe check seams, fasteners and any dents before water goes on.
- Wet the landscapingPlants and lawn near the roofline get a soak.
- Apply a mild mixThe soft wash goes on gently, not scrubbed in.
- Let it dwellShort and even, so the paint is not stressed.
- Rinse low and take photosA low pressure rinse, a plant rinse and pictures of the result and any fastener trouble.
What We Clean Off Metal Roofs
The list is simple, and so are the limits.
- Algae and mildewGreen or black film on north slopes.
- Salt filmA gray haze that dulls the finish.
- Pollen and bird messYellow dust and droppings.
- Light chalkingThe powdery surface that comes off on your hand.
Heavy rust and peeling paint go to a roofer or painter. We clean around them and show you photos.

Protecting Paint, Seams and Plants
Care on the roof means care around it too.
- No high pressure into seamsThe rinse is gentle and angled with the panels.
- Dry roofs onlyWe walk the roof only when it is safe and dry.
- Plant careSoaked before and after, with delicate beds covered.
- Galvanized and GalvalumeTreated with a mild mix that suits the coating.
Standing Seam Roof Cleaning and Other Panel Types
Standing seam panels need a gentle hand along the ribs, because the seams are where water gets in. Screw down panels have exposed fasteners, so we keep the rinse low and check each row.
Painted metal chalks over the years as the pigment breaks down. Chalky metal roof cleaning lifts the powder, and it often brings back some color. Faded paint may need a painter later.
Work Close to the Beach and the Barn
Salt film on metal roof beach house calls usually start with a rinse of clean water and a mild soap. Add algae and we use the soft wash first. Homes right on the ocean may need a rinse more than once a year.
Metal roof algae removal on inland buildings is a bit different. Shade, humidity and leaf debris feed the green growth, so the dwell and rinse change slightly.
Farm buildings and sheds get the same care. Barn roof cleaning Castle Hayne owners ask about is a simple wash of large panels, with a look at fasteners as we go.
Metal Roof Questions We Answer
Can you pressure wash a metal roof?
Gently. High pressure can scratch paint and push water past seams and screws. We soft wash and rinse at low pressure, which cleans well without that risk.
How do you remove salt film from a beach house roof?
Salt rinses off with clean water and a mild soap. If algae is also growing, we use a soft wash mix first. Homes right on the ocean may need a rinse more than once a year.
Can you fix rust on my metal roof?
We clean around rust but do not repair it. We show you photos of any rusty screws or panels so you can call a roofer.
