Helpful tips and advice for home maintenance from your roof to your porch.
Painting a roof can be dependant on what type of material your roof is made of. No matter what material your roof is made of the first step is always to clean your roof.
Cleaning Your Roof
The best way to clean a roof is to use a high pressure power washer, especially those roofs that have a rough surface. A high pressure washer will help remove the mould from within the pores of the surface.
Painting a Corrugated Roof
A new iron roof will need to be washed with a degreaser first, before you start painting. However if the roof is more than a year old and has weathered more than likely the oil from the fabrication has worn off and the iron will have been slightly etched from the weather, and you will not have to use the degreaser.
Unpainted iron will need to be primed first with a suitable primer, which is also important for any sheets of iron that may have been replaced on an existing roof.
Two coats of recommended paint. The choice of color is up to you. Remember lighter colors will reflect the heat and darker colors absorb the heat.
The quickest way to paint any roof is with airless spray. If you decide to paint your roof this way there is a specific technique to applying the paint.
Painting a Tiled Roof
Painting a tiled or shingle roof is usually because existing glaze has worn off and the roof is looking a bit shabby.
With tiled roofs there is an issue with ridge capping. They may need to be repointed and re-bedded before painting.
If the color has gone then you will need to sealer the roof first. Apply generously.
Again airless spray is the quickest and best way to paint a tiled roof.
