Gauge is the thickness
Corrugated iron sheet is called korkoro in Amharic. Its thickness is a gauge number. A lower number is a thicker sheet. G28 is the thickest of the common sheets and G35 is the thinnest. A thicker sheet lasts longer and makes less noise in rain.
The latest official rates for a fixed roof are ETB 1,370.13 per m² for G28, ETB 1,229.59 per m² for G30, ETB 997.16 per m² for G32 and ETB 833.46 per m² for G35.
What the rate covers
The rate is for the sheets, the nails and the labour to fix them. It does not cover the truss and the purlins that hold the roof. Those are carpentry or steel work with their own rates.
Shops sell sheets by the piece, in lengths from 1 to 6 metres. In October 2026, sellers in Addis Ketema listed sheets at ETB 680 to 750 per piece.
The price over time
A G28 roof went from ETB 1,356.18 in 2016 E.C. Q1 (Jul to Sep 2023) to ETB 1,370.13 per m². Roofing sheet moved less than cement and blocks in this period. Two values for Q2 2018 (G32 and G35) are left out, because the scan of that document is not clear enough to read them with confidence.
The rates are direct cost only. The bureau tells users to add overhead (up to 10 percent of direct cost for contractors of grade 3 and above) and profit (7 to 13 percent, by project size). VAT of 15 percent comes on top.
