How to Paint a Roof

Painting a roof isn’t a job to be rushed into, not least because there are particular precautions that you should take at various stages of the process. However, whatever type of material comprises the roof that you seek to paint, it’s crucial to give that roof a good clean before any paint is applied to it. You could clean it especially effectively with a high pressure water blaster, particularly if the roof’s surface is rough. That high pressure can help you to reach all of those little nooks and crannies, resulting in a thorough job. With that cleaning done, you need to choose the paint…


Which paint should you opt for?

Before you apply any commercial or industrial paint to that roof, you should consider which exact such paint – or paints – you should apply. The stock here at includes Cromar Renocoat Water-based Roof Tile Paint. This paint is intended for providing an enduring, protective and good-looking finish for slate and concrete roof tiles. It’s suitable for applying to any exterior roof. However, how exactly you should paint the roof can depend what type of roof it is; therefore, we are going to provide separate tips for tackling tiled roofs and corrugated iron roofs.


Tips for painting a tiled roof

If you are planning to paint a tiled roof because it looks slightly shabby, you might find that it actually looks good enough after simply a good clean. However, if it doesn’t, we would urge you to tackle the problem of ridge capping that arises with tiled roofs. You may need to have the roof’s ridge caps pointed and bedded before you start painting; the process of pointing a ridge cap is described here. Also, two coats of the right paint will be necessary.


Advice for painting a corrugated iron roof

What we have just said about layering two paint coats applies to any type of roof – including a corrugated iron roof. Before tackling a roof of this type, if the roof is new, it will be necessary to use a degreaser to wash it. However, you should avoid doing this should the roof be older than a year. You should also forgo this step if the roof has weathered; in other words, the oil from the fabrication process has worn away and weathering has caused slight etching to the iron.


Other tips for effectively painting a roof

Whatever colour you are considering for that roof, keep in mind that, while lighter colours will reflect heat, darker colours will absorb it. Therefore, lighter colours could be a better idea if you are eager for the roof to remain cool. Also, if getting your painting work done speedily is a high priority of yours, then airless spraying the paint would be a great idea. You will need an airless spray gun in order to do this, but you are likely to find this painting method quicker than brushing. The cost of getting hold of an airless spray gun should be easily worth it.
