Galvalume roof panel

Anyone has install those galvalume roof panel? How enduring are they? They are basically steel material with coating

How long would those panel endure and require another coating? Compare to shingles?

It all depends on the quality of the material. It's available with different thicknesses of steel and different manufacturers use different coatings of different thicknesses. I've seem cheap stuff start to show rust spots in five years while good stuff can easily go 20+ years without rust.

Yes, it really does depend on the quality. Most manufacturers will give you a warranty period for rust spots and rust through. A local comapny in my area warrenties it for 50 years before rust through.

I just did two roofs with 29 guage galvalume and the manufacturer warranties it for 40 years. The warrenty agaisnt color wear or fade is generally less if you go that route, but again, it depends on the manufacture and quality of the material.

Under which circumstances would you choose a heavier gauge like 26?

Provided the additional cost didn't wreck havoc on my finances - I'd always opt for the heavier gauge metal!
