Many people don't know that you can spray paint your existing roof tiles. However the simple answer is that it is possible to spray roof tiles and there is a lot of benefits in doing so.

You may be wondering, why is painting roof tiles not more common? The reality is, roof coatings are experiencing a huge resurgence in the last few years thanks to more advanced technologies being developed. Roof coatings were previously generally poor quality, meaning they could fail in a matter of years. This, along with unreputable companies selling roof coatings as energy efficient meant that painting roof tiles was something that homeowners were cautious to do.

Roof coatings cannot improve the energy efficiency of a property by insulating the roof tiles, This is because roof tiles do not transfer significant amounts of heat from a property when wet. If you want to improve the energy efficiency of your roof, loft insulation is the best option.

This is not to be confused with exterior walls that have been shown to be improved in energy efficiency when coated using a waterproof exterior wall coating. This is because exterior walls have been shown to transfer significant amounts of heat, leading to energy loss as a result. Over 35% of heat loss occurs through the wall of a property, and just 5% damp content within a wall can lower its insulation by 50%. By keeping exterior walls dry, you can improve their thermal efficiency significantly.

So if roof coatings cannot improve thermal efficiency of a property, what benefits do they have? Painting roof tiles can:

1. Improve the performance of the roof tiles by providing them with a new attractive colour

2. Extend the life span of the roof tiles by preventing the loss of structural strength in roof tiles through weathering, frost damage and salt efflorescence, plus by obstructing the growth of unsightly moss, algae and lichens
