1. Whether the roof insulation layer is thick enough, go to the sales office to see the drawings.
The roof is waterproof as long as it doesn't leak after the heavy rain.
3. Not only the roof insulation, but also the external wall insulation. After all, the top floor is not as good as other floors, and you can't have your cake and eat it!
4. the advantage is that it is high above the ground, overlooking the vast land, with good vision, no noise interference from the top people, and it is very comfortable to live!
