Metal roofs look amazing in the first few years after installation but can become chalky and a little drab looking after years of exposure to the elements.

Metal roofs can be repainted as a cheap alternative to replacing a tired looking roof or maybe to just update to a modern color. Using a professional is the way to go to get the best long-lasting effect, but you can also hire some equipment and do the job yourself.

How often does a metal roof need painting?

A new coat of paint increases the lifespan of your metal roof and lowers your energy costs. Typically, you can repaint your metal roof every 10-15 years, which is the average time it takes for the roof’s protective coating to break down due to weathering, biological growth, debris, and other organic deposition.

In all likelihood, roof replacement is probably the most expensive home maintenance job you will ever perform. The average cost to replace a metal roof ranges from $1,200 – $10,000 depending on the usual factors such as your roof’s size and the quality of the roofing materials used.

Painting your metal roof is only useful as long as the roofing sheets are in good structural condition. Severe rust, impact from projectiles, strong winds, and extreme weather conditions can damage or dent your roofing sheets, causing them to loosen and leak water into your home. When this occurs, replacing your roof is your only option.

How to paint a metal roof

Metal roof painting is a highly structured procedure, and painters must strictly observe the steps involved in the room painting process if you wish to achieve a quality and long-lasting finish. Metal roofs can be scorching hot during afternoons, so be sure to start the painting very early in the morning.

There are two main stages during the roof painting process: the preparation stage and the painting stage. These two stages comprise of several steps, which we will explain below:

Preparation Stage

Step 1
Remove flaking and other surface rust by scrubbing them off with a bristled or stiff wire brush. Scrub the entire roof as methodically as possible while covering as much surface area as you can.

Step 2
Sweep off all residues and debris, and hose down the entire roof with water in preparation for painting. You can wash the metal roof using trisodium phosphate TSP and water mixture (1 cup TSP mixed with 1-gallon water). You can either wash the roof by hand with a garden sprayer attached to a hose or with a power washer. Wait for the roof to dry completely before painting.

Painting Stage

Step 3
Apply paint primer to the metal roof using a paint roller. An extension pole can be attached to the end of the roller for easy reach. Use a primer that’s specifically formulated to prevent rust from forming on roofing sheets. Wait for the primer to dry completely before applying the first coat of paint.

Step 4
The final step is the process of painting the surface of your roof. Apply two coats of paint to the metal roof using either a paint roller or an airless spray gun. Start painting a new coat from different directions to ensure full coverage, and use a paintbrush to touch tight or hard to reach spots. Wait for the first coat of paint to dry before applying the second coat.

Maintenance tips after painting

No matter how great your roof paint looks, you’ll need to pay close attention to your roof and carry out regular inspections and maintenance activities to keep your metal roof looking like new.

Here is a list of maintenance tips:

  • Sweep your roof regularly to prevent the accumulation of debris. Decomposing debris on your roof surface can damage the paint coating.
  • Clear out your roof gutters to allow the effective discharge of rainwater and snow. Debris buildup along roof gutters and edges can trap water and moisture, leading to corrosion.
  • Inspect your roof for any missing, dislodged, or loose screws. Tighten or replace them to prevent leaking or loosened sheets.
  • Replace sealants on the seams and edges to prevent rust.
  • Check for holes and gaps in your metal roof and repair them immediately.
