How to paint a tiled roof

Painting your roof is a great way to add value to your home. While the job may seem daunting and not applicable to the DIY category, we want to assure you that if done properly and safely, it’s quite simple and easy and what is most important is to prepare thoroughly and use the right equipment.

Before you start painting, you need to clean your roof. High-pressure blasting is the preferred method. Make sure to remove lichen, bird droppings, wax or grease from the tiles, if any with the right chemical mixture.

While cleaning, check your roof for any broken or cracked tiles and replace them. If you see any damaged mortar around the ridge capping, remove the capping and apply new mortar and put the capping back in place. Start painting only after the mortar has dried fully.

Next, calculate the area of your roof and buy enough paint to apply three coats – one coat of Sealer/Primer and two coats of your desired colour.

The best and quickest way to paint a tiled roof is with an airless spray gun. Surface must be primed before applying one coat Acrylic Roof Sealer or Oil based Primer should that be required before applying two coats Deluxe Coatings Roof Coating.
