How To Paint A Metal Roof The Right Way

Plan For A Dry Day In Advance.

Painting your home outside on a wet day is not a good idea because the water can wash off the paint. Plan ahead and check the weather forecast to ensure a dry day for painting. The ideal time frame is 10 days to allow the paint to cure completely before any rain or snow. Start painting as early as possible in order to allow the paint time to dry in the sunlight.

Remove Old Paint

Then, use a scraper and carefully remove the old paint to allow your roof to be primed evenly. If you skip this step, your paint will be lumpy and peel. If the roof has already started to peel, it can be difficult to remove all the loose paint. The old paint will continue peeling once the new paint has been applied. This will cause bubbles under the new surface.

How To Get Rid Of Rust Spots

Your roof might have rust spots due to its exposure to different weather conditions. By vigorously scraping the rust and mold, you can remove them with a wire brush. After this step, you can wash the area in soapy water. Let it dry. You may need to repair the area before painting if the rust patches have penetrated the original roof.

Roof Power Washing

It is a good rule to never paint over a dirty roof. Power wash it first to remove any dust, mildew, or sand particles. Hiring a professional power wash will ensure this step is completed correctly. Otherwise, you may damage your siding, screens, and other roof components. The cost of a power wash by a professional is usually between $0.50 and $1 per square foot.

A professional can also soft wash your roof. Soft washing is a better option than using high-pressure water to clean the roof. It uses chemicals and a softer pressure.

Use A Primer

Priming your roof will help it adhere to subsequent layers of paint and prevent the paint from cracking. Make sure that the primer you use has titanium dioxide as a base to protect it from sun and rain. Let the primer dry completely after applying it.

Paint Your Roof

Make sure that the roller is designed for metal surfaces that are not flat and has a long handle to make it easier to use. One thick coat should be sufficient, but check the instructions for your paint to get more information.

Brush Sealant Over Your Roof

Paint sealants are best for metal roofs. A sealant protects your paint against the elements, preventing peeling. Apply the sealant using a roof brush when the surface has completely dried. It is sufficient to apply a thin layer of sealant on the surface. Too much sealant can cause cracking.
