While metal roofing is the most durable type of roof available it still needs routine maintenance and care. It will need to be kept clean. There is a way to keep the metal protected and make it more energy efficient at the same time. If the metal roofing is sealed and painted with elastomeric coating paint, it will last longer and the white tone will reflect the sun’s heat easier.

The first process is to seal the metal to protect it.

Step 1 – Applying the Sealant

You will need to buy the necessary amount of sealant. Measure the roof and find out how much you will need. Finding the best way up to the roof with the supplies you need to sweep and wash the roof down first and then let it dry. Take the time to inspect the roof while you are here for any places that might need extra cleaning or repair. Look for places that need sealant such as bare spots or places that have been patched in the past. You can either use the spray applicator or the paint roller to lay down the desired coats of sealant. Let this dry carefully before painting.

Step 2 – Wait

While the roof is drying from the sealant clean all materials carefully. It might be best to actually wait a day if possible to make sure the sealant has dried.

Step 3 – Assessment of the Dried Sealant

When the sealant seems to have dried completely, make your way to the roof in the best way possible with your supplies check the sealant for any bumps, chips or other issues.

Step 4 – Applying the First Coat of the Elastomeric Coating

If all seems to have dried well, begin spreading the elastomeric coating paint as you did the sealant only this time being sure to spray in even lines.  

Note – Elastomeric coatings are a type of paint that contains polymeric materials like acrylic and white pigment like titanium dioxide. These ingredients make the paint both opaque and reflective. This type of roof coating is very suited for use with metal roofing. It is usually applied thicker than paint and has two benefits. Elastomeric coating’s reflective nature is more energy efficient than most paints. It reflects back the light from the sun instead of absorbing it and becoming hotter. Since this is the opposite effect the sun has on metal this balances out that issue alloys have with being hotter in the summer months than most other roofing. Elastomeric coatings are also effective in solving roof leaks and are sometimes used to restore many different types of roofs.

Step 5 – Checking Your Work

While applying the elastomeric coat, make sure that no spots have been missed out. If needed, you will need to work over an area again. More than one coat of paint can be sprayed or rolled on in a day.  

After painting the roof will be more protected, but it will still be necessary to perform regular basic maintenance such as cleaning at least once a year.
