1. Using leftover paint

Most of the time, homeowners tend to cut costs by using leftover paint that was used for other parts of the house. Keep in mind that the material used to construct the rest of the house is not necessarily the same as the roof.
Homeowners are advised to invest in specialty paints that are specifically designed to protect your roof from the harsh elements. Paints specifically made for metal roofs must be heat, water, and pest resistant. Using the correct type of paint will ensure that your roof stays in top condition and will last a very long time.

2. Not preparing your roof

Prior to painting, make sure to pressure wash in order to remove oil, mildew, mold, and any other particles that might get in the way for the paint to adhere, preparation is key to ensuring the longevity of your paint job.
If you are repainting, ensure that you clean the surface first to remove the old paint as well as other dirt particles. In case of rust issues, make sure to sand or scrape the surface area and apply a rust converter to completely remove rust. Wipe off treated area with paint thinner to removed excess rust converter.
It is also a good idea to check for any cracks, or damage to your roof, it is a lot easier to repair these before the painting begins.

3. Incorrect application

A common mistake when homeowners DIY roof painting is that they either use too little or too much paint. Doing so will lead to peeling and other problems along the line. Make sure to apply primer first for the paint to adhere onto the roof’s surface. Once dry, apply 2 coats of desired paint color.
As licensed painters in Sydney, we suggest using an airless sprayer as it is the best way to paint a metal roof. However, should you decide to do it yourself, rollers and brushes are okay as long as it’s designed for use on metal.

4. Disregarding maintenance work

We often think that the job is done as soon as we’ve completed painting the surface. However, maintenance work must be completed regularly to keep the roof in pristine condition. Cleaning the roof once in a while is important to remove debris and other dirt particles. Take some time to inspect your roof for any leaks, rough patches, and bald spots that may eventually weaken the structure.
