One of the easiest ways to overspend on a Lagos construction or renovation project is buying materials through a contractor's markup instead of sourcing directly. Here is what to know about each major materials category.
Roofing sheets, trusses and accessories
Aluminium long-span, stone-coated, and Metcoppo are the most common roofing choices in Lagos. Prices vary significantly by gauge (thickness) and brand, and a thinner gauge sheet that looks identical will fail years earlier in Lagos rain.
What to check: always confirm the gauge (0.45mm, 0.55mm, etc.) in writing, not just the colour and profile. Find a roofing materials supplier
Plumbing materials and fittings
PVC and PPR pipes, fittings, water tanks, and sanitary fixtures. Substandard PVC pipes are a leading cause of the pipe bursts and leaks that plague Lagos homes within a few years of construction.
What to check: stick to recognised brands for anything under pressure (rising mains, distribution pipes), you can save on drainage pipes but not on pressurised lines. Find a plumbing materials supplier
Electrical cables and materials
Cables, conduits, distribution boards, circuit breakers, and switches. Undersized or substandard cable is a genuine fire risk, this is not a category to cut corners on.
What to check: ask for the cable's cross-sectional area (in mm²) and confirm it matches what your electrician specified for the load, not just what is cheapest. Find an electrical materials supplier
Tiles and sanitary ware
Floor and wall tiles, WCs, wash basins, and bathroom fittings. Lagos has a wide range of imported and locally-made options at very different price points.
What to check: buy 10% extra tiles beyond your measured area to account for cutting waste and future breakage repairs, matching batches later is often impossible. Find a tiles and sanitary ware supplier
Sand, gravel, block and cement
The foundational materials for any Lagos build, priced by trip (truckload) for aggregates and by unit for blocks and cement bags.
What to check: confirm the truck capacity being quoted (a "trip" varies by truck size), and buy cement close to when you need it since it degrades in Lagos humidity if stored too long. Find a block and cement supplier · Find a sand and gravel supplier
How to avoid overpaying
- Get at least two supplier quotes for any large materials order.
- Ask for delivery to be included in the quoted price, not added afterward.
- For anything structural or pressurised (cables, pressure pipes, cement), prioritise recognised brands over price.
