Why use reflective paint?

Well, let us tell you what it is first. Reflective paints reduce solar heat gain on darker coloured roofs. Because of the dark colour, roofing can absorb heat causing you problems in the future. By reducing the roof temperatures on a property, in summer you’ll find that you don’t spend as much money on air-con. You’ll be saving energy which is always a benefit!

You should use a paint such as Blackfriar Professional Solar Reflective Paint on a dark roof. This paint can be used on stable felt, bitumen, metal, concrete, brick and more roof surfaces, so it’s extremely versatile. After you use this paint, you’ll be left with a white, water-based finish that will give your roof solar reflectivity. It’s the ideal product to use if you want to add solar reflectivity to a new roof.

This special paint will reflect the sunlight that falls on the roof and disperse the heat from the roof. It can also help you to resist surface fungal growth, that’s two in one! If you really love a two in one, this is a self-priming two coat system as well.

  1. Lillian Schaeffer

    This is some great information, and I appreciate your point that reflecting roof paints can help you save energy. My roof is made of metal, and it’s a fairly dark color, so I’m sure it absorbs a lot of heat, especially during the summer. I’d like to save as much energy as possible, so I’ll definitely look into having cool roof coating applied. Thanks for the great post!

  2. I didn’t know that reflective paint was used on roofs. It looks like a great way to help cut back on energy costs. If you put this paint on a new roof how long can you expect it to last? Thanks for sharing this information!

  3. What can one do to a conservatory roof to make it cooler in summer and again warmer in winter????

  4. Thanks useful.

  5. I had no idea that reflective paint helps resist surface fungal growth. I can see why this would be a good thing to know if you are wanting a way to save on your energy bill and reduce any chance of fungus growing on your roof. My wife and I have been talking about ways we can save on our energy bill during the summer. I’ll have to mention this to her tonight.

  6. Thanks, This is great information.

  7. If you are applying the reflective paint to an existing flat felt covered roof, how will this affect the fire rating designation if , for example the existing bitumen felt roof has an AA rating?

  8. Hi. Can any of these paint be used on asbestos roofs?


    • Hi Ingus,

      Both products mentioned in this blog are suitable for asbestos – Blackfriar Professional Solar Reflective Paint and GacoPro Roof Coating.

      Best regards.


  9. Hi, I’ve a log cabin that’s got a black roof made from an EPDM sheet, it’s very waterproof, but really heats up in the summer. I’ve been looking for a suitable lighter shade paint that I could use to reduce the solar gain and just come across this article. From what I’ve seen on the internet, acrylic based paint is the preferred paint as it doesn’t interact with the EPDM membrane like some rubber/solvent based paints. Do you know if this is suitable for EPDM, or would you have any alternative recommendations?

    • Hi Matt,

      Thanks for getting in touch – we recommend using GacoPro Roof Coating for EPDM. The product page has data sheets and application guides under the “attachments” section, but if you need any further help then feel free to come back to us through here or via our technical support team on 0113 2455450 (option 2) or send a message to [email protected].

      Good luck with the cabin!

  10. Hi,
    Thanks for this info. We have lead sheathed flat roofs south facing which attracts a lot of heat during the summer months, which of the 2 products you mentioned be best ?

    • Hi Peter,

      Thank you for your question. The product we would recommend for this application would be Gaco Pro Roof Coating.

      Although not white or aluminium, it is a very light grey and performs better in terms of heat reflection than the majority of other coatings because of its chemical structure.

      This goes against the common way of thinking which says colours reflect, however this has been proven to not be the case when it comes to silicone roof coatings – the roof will reflect heat up to 70% better and be almost cool to the touch after applying GacoPro.

      I hope that helps, feel free to get in touch if you have any further questions.

      Many thanks
