Concrete roofing tiles in Kenya

In Kenya, concrete roofing tiles are mainly manufactured by Mareba at Industrial Area and Manson Hart in Nairobi.

Makiga engineering, also in industrial area, sells machines that can be used to produce concrete tiles at a small scale.

There has not been new technological advancement in Kenyan concrete roof tile. Advancements such as a wider range of colours, texture and light weight concrete , would enable a new entrant into the Kenyan market gain traction.
Both Mareba and Manson Hart are household names in Kenyan roof tile market, having been around for over 40 years.

This size costs kes 450 per m2, add overlap to bring to approximately kes 600 per m2.

This cost is more or less same to clay roof tiles.
