Cost of Roofing a 3-Bedroom Flat in Nigeria in 2026 (Full Naira Breakdown)
What roofing a standard 3-bedroom flat actually costs in Nigeria right now including sheets, timber carcass, labour, accessories, and how Lagos, Abuja and smaller cities compare.
The cost of roofing a 3-bedroom flat in Nigeria in 2026 typically falls between ₦1.6 million and ₦5.5 million, and sometimes higher, depending on the roofing sheet you choose, your roof design, your city, and the quality of timber going up before the sheets ever get nailed down. This guide breaks every one of those numbers down so you’re budgeting with facts, not vibes.

Why Roofing Costs Vary So Much
Ask five roofing contractors what it costs to roof a 3-bedroom flat, and you’ll likely get five different numbers, and not because someone’s lying to you. Roofing cost sits at the intersection of quite a few moving parts: the sheet material you pick, the gauge/thickness, your roof design (a simple gable roof is cheaper than a hip roof with valleys and multiple slopes), your city, and the quality of timber your carpenter is using.
Two houses with the exact same floor plan can have roofing bills that differ by a million naira or more, purely based on these choices.
What’s Actually Included in a Roofing Cost Estimate
When a contractor quotes you roofing cost, it should cover four separate components, even if it’s presented as one lump sum:
- Roofing sheets: the material itself (aluminium, stone-coated, zinc, etc.)
- Timber/roof carcass: the wooden trusses and rafters that support the sheets
- Labour: the carpenters and roofers who build and install everything
- Accessories: ridge caps, gutters, nails, foam/rubber seals, and fasteners
A quote that only mentions sheets and skips the other three isn’t a complete roofing estimate rather it’s a materials estimate. Ask your contractor to break these out separately so you can see exactly what you’re paying for.
Cost of Roofing Sheets Per Square Metre (2026)
A standard 3-bedroom flat needs roughly 150–200 sqm of roofing material once pitch, overhangs, and wastage are factored in. Here’s what that material costs per square metre in 2026:
| Roofing Sheet Type | 2026 Price Range (₦/sqm) |
|---|---|
| Aluzinc / zinc corrugated | ₦3,000 – ₦4,300 |
| Long-span aluminium (0.45mm–0.55mm) | ₦5,300 – ₦8,600 |
| Long-span aluminium (0.60mm–1mm, thick gauge) | ₦8,600 – ₦15,800 |
| Step-tile / Metcopo aluminium | ₦6,000 – ₦9,600 |
| Stone-coated steel tiles | ₦5,000 – ₦10,550 |
At 150–200 sqm, this alone puts sheet material cost somewhere between ₦700,000 (budget zinc, smaller roof) and over ₦3 million (thick-gauge or stone-coated on a larger roof), before timber, labour, or accessories are added.

Cost of the Timber Roof Carcass
Before a single sheet goes up, your roof needs a wooden frame that includes trusses, rafters, purlins, strong enough to hold the sheets, resist wind uplift, and last for decades. This is where a lot of first-time builders get caught off guard, because timber is priced and budgeted separately from the roofing sheets in most quotes.
For a standard 3-bedroom bungalow, a complete timber roof carcass (materials, transport, and carpentry labour) typically runs ₦1.2 million to ₦1.8 million, depending on wood quality (softwood vs hardwood), roof height/pitch, and design complexity. Hardwood costs more upfront but resists warping and pest damage far better over time, this is not the place to buy the cheapest timber on offer.
Price of Wood Planks for Roofing in Nigeria (2026)
That ₦1.2 million–₦1.8 million timber figure is made up of individual plank purchases, priced by size and wood type at the timber market. Knowing the going rate per plank helps you sanity-check a carpenter’s material list instead of just trusting the total they hand you.
Softwood and gmelina (mid-tier hardwood) planks, 12ft length:
| Size | 2026 Price Range |
|---|---|
| 2×2 (softwood) | ₦700 – ₦900 |
| 2×3 (softwood) | ₦850 – ₦1,050 |
| 2×4 (gmelina) | ₦1,500 – ₦1,900 |
| 3×4 (gmelina) | ₦7,200 – ₦9,000 |
| 1×12 (gmelina, facing board) | ₦6,000 – ₦7,500 |
| 4×4 (gmelina) | ₦8,500 – ₦10,500 |
| 2×8 (gmelina) | ₦11,000 – ₦13,500 |
Plywood, per sheet:
| Type | ¼-inch | ½-inch | ¾-inch |
|---|---|---|---|
| Afara plywood | ₦2,500 – ₦3,200 | ₦4,300 – ₦5,000 | ₦6,200 – ₦7,500 |
| Obeche plywood | ₦1,900 – ₦2,800 | ₦3,400 – ₦4,400 | ₦5,200 – ₦6,200 |
Gmelina remains the most commonly specified wood for Nigerian roofing carcasses because it’s durable, workable, and reasonably termite-resistant for the price, which is why it dominates the mid-to-large size categories above. Afara and Obeche plywood tend to show up more in facing, soffit, and ceiling work than in the structural trusses themselves.
A necessary caveat: timber pricing swings noticeably by market, region, and season (expect a bump during the rainy season when sourcing gets harder), so treat these as a planning range, not a fixed quote and always confirm current rates at your local timber market before finalizing a budget.
How to Estimate the Amount of Wood You Need
Before you can turn the price table above into an actual budget, you need to know roughly how many planks of each size your roof requires. Three things determine that:
Your roof’s square footage. This is the starting point for everything, in broad terms, the total volume of timber your trusses, rafters, and purlins will need to cover.
The specific plank sizes your design calls for. Different parts of a roof frame use different sizes, smaller sections (2×2, 2×3) typically go into bracing and lighter framing, while larger sections (3×4, 4×4, 2×8) carry more structural load. Your roofing plan (and the type of roof whether gable, hip, or something more complex) determines the mix, so this isn’t a one-size-fits-all calculation.
Current market pricing. Once you know the quantity and sizes, multiply against current rates like the table above to arrive at a working budget. Because timber prices move with market conditions, treat any total as an estimate to walk into the timber market with, not a final number to commit to before you’ve confirmed it in person.
Labour and Installation Costs
Labour for roofing installation is usually priced either as a flat job fee or per square metre, and it varies significantly by state. As a rough 2026 guide, installation labour (separate from the timber carpentry above) typically adds ₦250,000 to ₦600,000+ to a standard 3-bedroom roofing job, depending on roof complexity and location. Lagos and Abuja labour rates sit at the higher end of that range; secondary cities are generally cheaper.
Accessories: Ridges, Gutters, Nails, Foam
Accessories are the small line items that add up faster than people expect. For a standard 3-bedroom flat, budget roughly ₦80,000 to ₦200,000 for:
- Ridge caps (the covering along the roof’s peak)
- Gutters and downpipes for rainwater management
- Roofing nails/screws and rubber washers
- Foam or sealant strips to close gaps under the ridge
Skipping proper ridge and gutter accessories to save money here is one of the most common ways a decent roof develops a leak within its first rainy season.
Total Cost of Roofing a 3-Bedroom Flat by Material (2026 Table)
Putting sheets, timber, labour, and accessories together, here’s the realistic all-in cost for a standard 3-bedroom flat (150–200 sqm roof area) in a mid-tier Nigerian city:
| Roofing Material | Total Cost (Materials + Labour) 2026 |
|---|---|
| Zinc/aluzinc roofing | ₦1.2 million – ₦2.2 million |
| Standard long-span aluminium | ₦1.6 million – ₦4.5 million |
| Premium/thick-gauge aluminium | ₦3 million – ₦5 million |
| Stone-coated tile roofing | ₦2.5 million – ₦5.5 million+ |
These figures already account for timber, labour, and accessories bundled into the total, not just sheet cost alone.
Cost by City: Lagos vs Abuja vs Smaller Cities
Location changes your roofing bill more than most people expect, mainly through labour rates and transport costs on materials.
- Lagos and Abuja: Expect to pay 15–30% above the mid-tier figures in the table above, largely due to higher labour rates and demand.
- Port Harcourt: Runs close behind Lagos and Abuja, with similar upward pressure on labour.
- Kano, Enugu, Benin, and similar secondary cities: Typically 15–25% cheaper for the same roofing scope and skill level.
If you’re building remotely as a diaspora Nigerian, always get at least two independent quotes from your specific city because a Lagos-based supplier’s price list won’t reflect what you’ll actually pay in Enugu or Uyo.
What Drives Your Roofing Cost Up or Down
Roof design complexity. A simple gable roof (two slopes, no valleys) is the cheapest to build. A hip roof with multiple slopes, valleys, and dormers needs more timber, more sheet cutting, and more labour hours, sometimes adding 20–40% to the cost.
Roof pitch/height. A steeper pitch needs more roofing material to cover the same footprint and more timber for the taller trusses.
Sheet gauge. As shown in the price table, moving from 0.45mm to a thicker 0.60mm+ gauge can nearly double your material cost per square metre.
Overhangs. Wider eave overhangs (common for shading verandas in Nigerian homes) add extra square metres of coverage that many first-time budgeters forget to account for.
Wastage allowance. Always budget 5–15% extra material for cutting waste, especially on complex roof designs. This is standard practice, not a contractor padding the bill.
How to Avoid Overpaying for Roofing
The single biggest reason Nigerians overpay for roofing isn’t the sheet price rather it’s the absence of an itemised quote and independent verification. A verbal “I go do am for you for two million” quote tells you nothing about gauge, timber quality, or what accessories are included.
Before signing off on any roofing budget:
- Get the quote broken into sheets, timber, labour, and accessories separately
- Confirm the actual gauge of the sheets, not just the number quoted verbally, a micrometer check takes minutes and saves millions
- Ask what wood species and treatment is being used for the roof carcass
- Have someone independent, not the person selling you the materials to confirm the installation meets spec before final payment
This is the exact gap that independent site supervision closes. As a construction project manager running Buildtracka Integrated Services, I’ve seen roofing invoices that looked perfectly reasonable on paper turn out to specify one gauge and deliver another, a difference that’s invisible to most homeowners until the sheets are already up. A supervisor on-site checking deliveries against the quote before installation begins is one of the cheapest forms of insurance in the entire build.
Frequently Asked Questions About Roofing Costs in Nigeria
How much does it cost to roof a 3-bedroom flat in Nigeria in 2026? Between ₦1.6 million and ₦4.5 million for standard aluminium roofing, or up to ₦5.5 million+ for stone-coated tiles, including sheets, timber, labour, and accessories.
How many square metres of roofing does a 3-bedroom flat need? Roughly 150–200 square metres, depending on roof design, pitch, and overhangs.
Is roofing cost the same as roofing sheet cost? No. Roofing sheet cost only covers the material. Total roofing cost includes the timber carcass, installation labour, and accessories like ridges, gutters, and nails.
What is the cheapest way to roof a 3-bedroom flat in Nigeria? Zinc/aluzinc corrugated sheets on a simple gable roof design offer the lowest total cost, typically ₦1.2 million to ₦2.2 million, though with a shorter lifespan than aluminium or stone-coated options.
Why is roofing more expensive in Lagos and Abuja? Higher labour rates, higher demand, and increased transport costs for materials push roofing costs 15–30% above what you’d pay in secondary cities like Kano or Enugu for the same scope of work.
Does roof design affect the cost significantly? Yes. A simple gable roof is the cheapest option. Hip roofs with multiple slopes and valleys can add 20–40% to the total cost due to extra timber, cutting, and labour.
How much does the timber for a 3-bedroom roof cost separately? Roughly ₦1.2 million to ₦1.8 million for a complete timber roof carcass, depending on wood quality and roof complexity.
Should I pay for roofing in one lump sum or by component? Always request an itemised quote separating sheets, timber, labour, and accessories. A single lump-sum figure makes it difficult to verify you’re getting what you’re paying for.
Final Word
The cost of roofing a 3-bedroom flat in Nigeria in 2026 isn’t a fixed number, it’s a range shaped by the sheet you choose, your roof design, your city, and, honestly, how carefully you verify what’s being delivered against what you were quoted. Budgeting ₦1.6 million to ₦5.5 million gives you realistic room to plan, but the real savings come from an itemised quote and someone checking the work before the scaffolding comes down.
