Can I use plastic film to make roofing waterproof?
No, roof waterproof is a crucial step.
Not too good, poor corrosion resistance, can be used with waterproof cement tiles (can be thinner, cost saving) if there is a groove with a hose with waterproof ribbon, it has good corrosion resistance and decoration of a long time
Plastic film can be aged, broken, and without strength, easy to damage.
