ᐅ Roof Coating with Climate Benefits?

I am planning to apply a new coating to my roof soon. At the moment, I am wondering whether to use a regular roof paint or one with a "climate effect." It is said that the climate paint can partially reflect sunlight and reduce heat buildup in the attic during summer. Is this really true? Has anyone had good experience with this?

In theory, this is possible, but whether the coating actually works in practice depends on experience. Unfortunately, I have no experience with roof coatings. For windows, there are also reflective coatings, but these do not prevent the room from heating up during summer heat. Sunlight consists of different wavelengths, and each material reflects certain wavelengths (explained somewhat simplistically). A film made of a specific material, for example, aluminum-coated, therefore only reflects the portion of light that aluminum can reflect.

Yes, I also have some doubts about whether the coating can really have a significant impact on indoor temperatures. I think it would be better to invest the money in conventional roof insulation rather than a "climate roof coating."

Yes, with proper thermal insulation you will be better off.
