Painting Your Roof 

Painting your roof is a great way to add value to your home and make it stand out from all the other homes in your neighborhood. To get the job done properly and safely, it’s important to prepare thoroughly and use the right equipment.


Before painting you need to prepare your roof for the paint job. To achieve this, you need to give your roof a clean. You can use a hose and scrub down with a broom You could also use chemicals, should you need to clean lichen from the tiles.

Tiled or Corrugated Roof Preparation

For a tiled roof, you need to check your roof for any broken or cracked tiles and replace them. To repair any damaged mortar around the ridge capping, remove the capping and apply new mortar and put the capping back in place. It’s important to make sure the mortar is dry before you start painting. To clean a corrugated roof, you may wash it with a degreaser. However, if your roof is unpainted or you have any unpainted replacement sheets you should then give it a coat of primer. Make sure this is dry before you start painting.

Choosing Your Paint

Calculate the area of your roof and buy enough paint to apply two coats. It’s always a good idea to get a colour that compliments the rest of your house, and remember that darker colours absorb heat and lighter colours reflect it. This plays a significant role on the humidity of your home.

Painting Your Roof

The quickest way to paint a tiled roof is with an airless spray gun but you may also use a brush. You need to start by using a water-based paint but if your roof’s colour is completely faded, then it would be beneficial to apply a thick coating of sealer first.

Buy paint that is designed for metal roofs because they adhere to the material better and hold up against the elements. Like tiled roofs, airless spraying is the best and quickest way to paint but you can also buy paint rollers shaped like corrugated iron. However, you will need a brush to paint the corners and ridge caps.

For safety, make sure that you’re wearing the correct clothing and gear. Always try and have someone along with you at all times, or if you just can’t see yourself going through all the work on your own then you could hire a painting contractor like The Damp Proof Company, who are available in Johannesburg and Pretoria.
