In Nigeria, one of the largest markets for building supplies is for roofing sheets. You would anticipate their demand to be quite high given how crucial they are to construction projects, especially in a nation where buildings are being constructed on a daily basis.

Residential buildings like residences, hotels, and hostels are typically made to appear like they serve a certain purpose from the top. Moreover, there are buildings constructed for commercial uses, such as factories, banks, public offices, and restaurants. All things considered, a roof with a steeply pitched truss often requires more roofing sheets than a roof with a moderate slope. In contrast, a complex or difficult roof plan will necessitate the use of more roofing sheets than is possible with a basic roof plan, and of course, the more area that has to be covered with sheets, the greater the cost to the customer. These and other elements have a significant impact on the overall cost of roofing and the cost-effectiveness of a specific fashion in Nigeria.

These Stone-coated roofing sheets are in more demand on the market for use on expensive roof projects in major cities around the nation since they are strong, dependable, colorful, attractive, and ecologically beneficial.

Compared to most other types of roofing sheets, they often have a longer lifespan, are more dependable, and can handle extreme temperatures better. Building owners seldom need to replace the sheets since upkeep is simple and they can usually rely on them.

This was made ideal by coating it with bitumen and then covering it with sand, stone, or other materials. According to their description, stone-coated roofing sheets are made of refined metals, often steel, that are covered in stone chips and attached with an acrylic film on top of galvanized steel. The majority of them are oven-baked with a life expectancy guarantee of around 50 to 70 years, which eliminates the need for replacement and some other unneeded maintenance charges that would have increased the lifecycle cost over time, particularly during refurbishment.
2. Aluminium Roofing Sheets
Aluminum roofing sheets are by definition roof materials formed entirely of the metal Al or its alloys with components like copper, tin, manganese, silicon, or magnesium, etc. This is done, among other intended beneficial attributes, to increase its tensile strength, flexibility, ductility, and recyclability. These sheets are used in a variety of applications, including as the cladding of walls, awnings, gutters, and sidings.
According to use data, Nigeria’s most popular roofing sheet type at the moment is aluminum. Aluminium roofing sheets are extremely dependable and durable. Regardless of changes in weather or temperature, the majority of dealers guarantee over 50 years of use for the roofing sheet. This can be explained by its low cost, light weight, durability, improved corrosion resistance, acceptable insulation, and inability to burn during fire outbreaks. It has certain drawbacks, one of which is the noise it produces during rain and the cracking sound it makes during periods of intense sunlight.

| Step-tile | 0.45 mm | N3,100 |
| Metcoppo | 0.55 mm | N4,000 |
| Metcoppo | 0.50 mm | N3,450 |
Aluminium roofing sheets, While one of the most sought-after roofing materials, aluminum roofing sheets are less durable than stone-coated roofing sheets since they have a propensity to corrode over time. Despite this, they continue to be among the most popular roofing sheets in the nation, which does not diminish their quality.
Any Purlin built of steel or wooden can have aluminum roofing installed on it according to requirements.
3. Fibre Britment Roofing Sheets
- Each square meter of Fibre Britment Step-Tile Roofing Sheets costs 4,900 naira.
- Each square meter of Fibre Britment Roofing Sheet costs 3,400 naira.
4. Fibre Cement roofing sheet
Fibre Cement roofing sheet have been in use for so long, they have truly withstood the test of time. Fibre cement sheets with flat surfaces continue to be among the best cladding materials, while those with corrugated finishes are still utilized for roofing. Overall, the cost of a square meter of fiber cement roofing sheet in Nigeria ranges from 4,000 to 5,000 Naira.
The name is frequently confused with Fibre Britment roofs, which have already been phased out. While fiber cement roofing sheets are still popular, demand is declining as consumers turn their focus to metal alternatives. While they are simple to break, purchasers believe that they are more durable than corrugated zinc roofing sheets.
Fibre cement boards are essentially slates constructed of composite materials like cellulose fibers and Portland cement that have been blended with water and other chemicals to create the hard, non-metallic, non-combustible, heavy, well insulated, opaque profiles that are familiar to us today. These cement sheets are occasionally reinforced by their producers with asbestos to give them certain strong qualities.
5. Swiss Roofing Sheets
Swiss roofing sheets are now the most costly roofing sheet in Nigeria since they feature all the wonderful and necessary characteristics of a normal roofing material. Purchasing it beforehand necessitates placing a pre-order with importers, who will ultimately raise the price owing to the dollar-to-naira exchange rate. Due to the lower cost of national distribution, Swiss Metrotiles Ltd currently sources these items through their manufacturer in Switzerland.
There are very few roofing sheets that can compare to Swiss Roofing sheets in terms of beauty, class, elegance, and durability. In Nigeria, they are not the most often used kind of roofing sheet. This is mostly because of their high cost. The price per square meter for a typical Swiss Roofing sheet is from N6,000 to N9,000.

Important Notices Before Choosing Your Roofing Sheet
Each style and type of roofing sheet requires a particular sort of woodwork. The timber framework beneath stone-coated roofing has to be tightly fixed. Thus, be prepared to pay significantly more on the woodwork if you choose stone-coated roofing.
Choose your roofing style before beginning any woodworking. This is due to the possibility that the woodwork for one form of roofing may not be adaptable to another. For instance, the woodwork for step-tile aluminum roofing will not fit for longspan aluminum roofing. Similar to how stone-coated roofing will not work with the woodwork for step-tile aluminum. The woodwork for stone-coated roofing may, however, be used to any kind of roofing.
There are several brands and degrees of quality available for both stone-coated roofing sheets and step-tile aluminum roofing sheets. So, you should be aware of dishonest roofers who offer prices for high-end, pricey brands but then purchase less expensive, subpar brands that lose their appeal after a few years.
Calculating The Amount Or Quantity Of Roofing Sheets For A Structure
The different parts of a typical roof, such as the King post, Structs, Rafter, Tie beam, Purlin, Eaves overhang, Ridge, etc., are visible from the simple roof layout shown above.
We must be aware of the numerical values for at least two sides of the traingle in the diagram in order to compute the amount of roofing sheets (Side A, B & C).
The hypotenuse, or Side A, is obtained using known slopes.
Half of the building’s breadth, or Side B, is adjacent and easily accessible.
The length of the roof height/King post is roughly represented by Side C, which is the opposite (if any).
Take the King post’s height to be 1,200 mm, the block wall’s overall length to be 6,500 mm, and its width to be 3,600 mm based on our sketch.
We divide 3,600 by 2, which gives us 1,800, and we add one side of the eave overhang to the triangle to get 2,400 mm, which is the entire sloping length.
As a result, A = X , B = 2.4 m , C = 1.2 m
Using the use of the Pythagorean Theorem, which states that A² = B² + C², we were able to determine X to be 2.68 meters.
We now multiply the two sides of the eave by the WHOLE Lenght of the end-to-end block wall to arrive at 7,700mm, which is the area of just half of the basic roof type. To obtain 4,800 mm, we also use the same procedure for the WIDTH.
Hence, 7.7 x 4.8 = 36.96 m² of roofing sheets are required for this project, which becomes 36.96 m² multiplied by two to become 73.92 m².
