Which is better for a shed roof?

The Gibraltar panel is enough for a small shed and costs less per panel. For a shed over about 100 sq ft, the wider Tuff-Rib panels mean fewer seams and a painted finish that lasts longer.

The Tuff-Rib, mainly because of its painted Galvalume finish and 40-year finish warranty. Unpainted galvanized steel like the Gibraltar panel dulls over time and has no stated finish warranty.

Is the Tuff-Rib worth the extra money?

Per square foot the gap is small: about $1.67 versus $1.18. On a full roof the painted finish, thicker 29-gauge steel and 40-year warranty justify the difference. For a quick patch, the Gibraltar panel is the better buy.

Can I use either one for siding?

Gibraltar lists siding as a use case. Metal Sales lists the Tuff-Rib for roofing only, so check with the maker before using it on a wall.

What roof pitch do they need?

Gibraltar requires a slope of 3/12 or steeper. Metal Sales does not state a minimum pitch for the Tuff-Rib, so follow its installation guide and lap the panels with the gasket.

How much do I need for a 10 ft by 12 ft roof?

That is 120 sq ft. It takes about 7 Gibraltar panels or about 4 Tuff-Rib panels once you allow for laps and waste.
