I need to know if 26 gage metal roofing will hold up in hurricanes. The material that I am building with is such and it has to have documention to say so. Will it pass and is there some proof I can send the city?

There are wind maps of Florida in the Florida Building Code which dictate the wind uplift pressure required based on location, building height and roof slope. In Florida roofing products are required to have a product approval which indicate that the product is tested and approved and will provide a wind uplift rating in PSF with a 2/1 safety factor. Ask the manufacturer of the roofing material to provide a copy of their product approval. Top answer your question on 26 gage, products are designed to meet the wind uplift and not dependant on gage. Some areas in FL require a minimum 26 ga to resist the wind bourne debris. Metal has an excellant wind resistance.

would it depend on the appication, all metal roofing products use diffrent fastening systems. Gauge will make a diffrence but would you agree that the complete system you buy is more important then gauge.

Absolutely. Gauge is just one component of the equation. A poorly designed or mis-installed heavy gauge product may not perform nearly as well as a properly installed and well designed lighter gauge product. Todd Miller
