Tips and tricks when in comes to roof painting and roof restoration

Painting your own roof can be a daunting task. Not only is it high up, it can also be slippery and steep. Safety is your number one concern when going DIY on repairing and spraying your roof. Im going to list a few steps that will help any home owner know the ins and outs of roof restoration.

1. Edge protection is your first stop when cleaning a roof and also painting a roof, most scaffolders can come do this and install hooks to connect your rope and harness to.

2. High pressure cleaning your roof should be a minimum of 4000 psi running at least 21 litres per minute. this would equate to a 20hp machine with a good solid italian pump. Most hire shops will sell 13hp machines, this wont be sufficient and wont clean your roof thoroughly enough. You will also need to hire a rotary cleaner which is an attachment that connects to the end of your pressure washing line, Getting one with a good solid brush will make your job much easier. After cleaning the whole roof, its best to go over the roof quickly with a turbo lance to clean off any extra dirt thats sitting on roof after the rotary clean. Dont forget to turbo blast gutters and facia afterwards as they can get quite dirty!

3. Repairs and Repointing – Changing tiles is one of the most important things you can do when repairing. Looking closely for hairline cracks and broken edges. Using a flexible pointing mix that is pre made and ready to work with is best. It will take some practice and time to get the technique right, making sure you work really fast to keep a smooth finish and not letting the pointing mix to dry, as it does dry fast! very fast.

4. Blow roof down using a large petrol blower, focusing on edges and starting from the top of the roof to make sure anything that is sitting on the surface is blown off.

5. Covering all solar panels, skylights, hot water systems with a plastic sheeting and id recommend to use a good cloth tape to hold everything down, as the pressure of the spray can be quite intense.

6. Sealer binder coat, This coat is critical as it seals the roof and gives the paint a good solid surface to stick to. Poorly primed roofs often end up peeling and creating a huge mess for the next contractor to fix, often taking 3 – 4 days of solid jet blasting!

7. Roof painting coats, You will want to use a good quality roof membrane, and a top quality airless paint sprayer. Tools and equipment can much a huge difference to your final finish when doing a roof restoration, which is crucial when spraying a roof. I would recommend a Graco 1095 or larger. Starting from the top of the roof and spraying 4 – 5 tiles up and down, from right to left. Making sure you you hit each and every tile nose. Two thick coats will be required if you want your roof to last well into the future!
