The cost of building as well as roofing a 2-bedroom flat in Nigeria largely depends on a number of factors and it varies from one region to another. Factors such as foundation type, the price of the building materials and labour, the house design, the type of roof and internal finishing among others.
To determine how much it cost to roof a house in Nigeria, you need to first calculate the area to be roofed in metre square. That is, the building dimension measured on both the length and breadth along with the ridge cap, ceiling, valley gutter, gutter trimming, cladding, board among others. Some of these measurements can be gotten from the roof plan or better still measured physically again during construction.
Originality and Authenticity of Sheets
Some sheets change colour under few years of exposure to end up looking like a running splash of gold and rust.
The most preferred choice of roofing material for many home builders in Nigeria is the aluminum roofing sheets because it is less corrosive and doesn’t leak, unlike zinc roofing sheets. There are two types of aluminum roofing sheet: long span corrugated aluminum roofing sheet and step tile aluminum roofing sheet. They come in varying colors such as red, blue, yellow, green, chocolate and brown. These type of roofing material is commonly used in Abuja, Lagos, Port Harcourt and other major big cities in Nigeria.
Zinc roofing sheet is commonly used in ancient cities like Ibadan. They are comparably low compared to the other types of roofing sheets. Zinc sheets are strong and have the ability to withstand heat and weight.
Asbestos is also cheap and it has the ability to absorb heat and resist corrosion although it is not environmental friendly. It has been banned in many western countries due to health issues associated with it.
Stone-coated or stone chip roofing tiles are made from an alloy of aluminum and zinc also as known as “galvalume” or “Alu-zinc” metal sheets as the base metal for this roof covering. There are different designs for stone coated roofing tile which includes shingle, bond, classic, Roman, Milano and shake design. However, the names may differ from one manufacturer to another.
