I have heard that 29 gauge metal has a higher tensile strength to it, 80,000 psi. I heard that 26 gauge has a lower tensile strength to it, around 40,000 to 50,000 psi. My question is 1. Is that true that 26 gauge metal is softer than 29 gauge metal so hail would damage 26 gauge metal more? thanks,

Certainly all things being equal a heavier gauge product will be more impact resistant. However, heavily formed products will be more impact resistant than lesser formed ones. And products that rest close to the roof deck will also fare better. Also, more heavily formed products will tend to mask or hide minor damage fairly well. I hope this helps.
