The uppermost layer of the forest is called the canopy. It consists of the tallest trees that form a continuous leafy roof over the layers below. The canopy provides shade, shelter, and food for many animals living in the forest.
Just 2 layers I recommend, because if you add an additional layer the roof will get damage and collapsed.

Torch-on roofing, also known as torch-down roofing, is a flat roof covering solution that consists of three layers of modified bitumen (felt) melt-welded to the roof surface and each other with a blowtorch to create an impenetrable, waterproof seal.

Removing deep snow in layers and removing snow on both sides of a low-pitched roof as you go.
The different layers on a roof include the decking, underlayment, shingles or other roofing material, and flashing. These layers work together to provide protection from the elements, such as rain, snow, and wind. The decking provides a base for the roof, the underlayment acts as a barrier against moisture, the shingles or roofing material provide the outer layer of protection, and the flashing helps to prevent water from seeping into vulnerable areas. Together, these layers contribute to the overall strength and durability of the roof, ensuring its functionality and longevity.

When using a roof rake on a metal roof to prevent snow buildup and potential damage, it is important to follow these best practices: Use a roof rake specifically designed for metal roofs to avoid scratching or damaging the surface. Start raking from the edge of the roof and work your way towards the center to prevent snow from sliding down and causing injury. Avoid using excessive force or pressure while raking to prevent denting or bending the metal panels. Clear snow regularly after each snowfall to prevent excessive weight buildup and potential structural damage. Consider hiring a professional if you are unsure about safely using a roof rake on your metal roof.
The thin piece of wood used to cover a roof is called ply board or deck board. Plyboard is a sheet material manufactured from thin layers or plies of wood veneer that are glued together.
