Materials for Metal Roof Painting Projects

When painting metal, the surface should be thoroughly cleaned and rust spots should be removed. Old paint can be scraped away and rust may need some treatment with vinegar or rust remover. Typically sanding and or grinding to remove surface rust are necessary. Sometimes sandblasting is also recommended depending on the conditions of the roof at the start of the project. After all loose paint and rust have been removed, it’s time to power wash the surface to remove any accumulated dirt or debris that may be lingering on the roof.

Special primers are usually used for metal materials, for the paint to hold up over time, a good primer (i.e: rust inhibitor) is important. Paint rollers with long extensions or paint sprayers are typically used for roof projects.
