Which is better for a house roof?

The MasterRib 26 ga. It is thicker, has a 3:12 minimum pitch, a bell-top rib for wind-driven rain, and a 45-year limited finish warranty. The corrugated panel is better suited to sheds, fencing and utility structures.

The MasterRib carries a 45-year limited warranty on its painted finish and its 26 gauge steel resists denting and wind damage better. The Galvalume corrugated panel resists corrosion well but is thinner and has no stated warranty.

Is the MasterRib worth the extra money?

At $44.50 versus $28.00 as of November 6, 2026, yes for a roof or a visible wall on a building you plan to keep. For a fence, raised bed or patch job, the cheaper corrugated panel does the job.

How much area does each panel cover?

The MasterRib covers 36 in of width in fixed 10 ft to 16 ft lengths. The corrugated panel is 26.5 in wide and covers 24 in with a one-rib overlap, or 21.5 in with a two-rib overlap, in lengths from 1 ft to 14 ft.

Can I use the corrugated panel on a low-slope roof?

No stated minimum pitch is given, and corrugated panels generally need more slope than the MasterRib's 3:12. For low-slope work, use the MasterRib or another panel rated for it.

Can I get the corrugated panel shipped?

No. It is local pickup only in Lake Stevens, WA. The MasterRib ships from PBS Direct.
