Roofing in the Republic of the Congo

The Republic of the Congo (Congo-Brazzaville) lies on the west bank of the Congo and Ubangi rivers, with equatorial forest in the north, savanna plateaus in the centre and a short Atlantic coastline around Pointe-Noire. Most of its people live in the urban corridor from Brazzaville to Pointe-Noire, where houses are commonly built of concrete. In villages, houses are typically of mud brick with thatched or metal roofs.

Climate and hazards

The climate is equatorial and humid, with heavy rainfall and high temperatures for much of the year. Roofs must shed intense rain and resist rot, insects and mould; metal sheets bring heat gain, and on the coast salt air speeds corrosion.

Roofing history

Detailed historical records of roofing are scarce. The lower Congo region was part of the cultural world of the old Kongo kingdom, whose capital, Mbanza Kongo, lies in present-day Angola. In the northern forests, Baka forest people build hemispherical leaf huts (móngulu) in their camps, a building tradition shared with forest peoples across Central Africa. Poles cut from the forest remain an important building material for houses across the Congo basin.

Traditional and vernacular roofs

• Mud-brick house with thatch: the common village house, laid out along villages planned with one wide central dirt street crossed by smaller streets at right angles. Cooking and much social life take place at the front of the house.
• Móngulu: dome-shaped leaf hut of the Baka (see Mongulu).
• Pole-framed houses: forest poles are widely harvested for house frames in the Congo basin.

Roofing today

In villages, mud-brick houses are covered with either thatch or metal sheets; urban houses are made of concrete, often with a small garden. Nearly 90% of homes are owned by individuals or families.
