How to make a building roof insulated against solar heat?
Hi, my building is hot in temperature in summers, so I am finding ways to tackle the problem by placing some heat insulating materials against the sunlight on the roof of my building.
I have found several possible solutions, but none of them close to perfect.
1. grass layer: hard to maintain
2. heat-insulating brick: might be too heavy to carry them to the roof
3. heat-insulating coating: would it be damaged if we step on them?
Are there things like heat-insulating carpets that would be convenient to instal?
If you’re redoing the roof, a radiant barrier under the sheathing helps. So does insulation. And also, if there is an attic space there, consider putting in a fan to blow the hot air out.

Closed cell spray foam applied to the inside of your roof sheathing will work just fine. It needs to be installed by a specialty contractor. Good Luck
