Longspan vs Step Tile vs Metcopo — Which Aluminium Roofing Sheet Is Best for Your Project?

If you are building or renovating in Nigeria, one of the first questions you will face is which aluminium roofing profile to choose. The three most common options are long span, step tile and Metcopo. Each has its own strengths and trade-offs when it comes to cost, appearance, durability and installation. This side-by-side comparison will help you pick the right profile for your specific project.

Long span aluminium roofing sheets are the most economical option. They are produced in continuous lengths that span from the ridge to the eave of your roof, which means fewer joints and a lower risk of leaks. Starting from around ₦4,300 per square metre for 0.40mm thickness at Gods Promise Aluminium, long span sheets offer the lowest entry price of the three profiles. They are ideal for large-area roofing such as warehouses, factories, churches and budget residential projects where cost efficiency is the priority.

Step tile aluminium roofing sheets cost more than long span — starting from about ₦5,600 per square metre for 0.45mm at our factory — but they provide a more decorative finish. The stepped profile mimics the look of traditional clay tiles, giving your building a more refined, finished appearance without the weight and fragility of actual clay tiles. Step tiles are hugely popular for residential duplexes, estate developments and any project where kerb appeal is important.

Metcopo aluminium roofing sheets sit at a similar price range to step tiles but offer a different aesthetic. The Metcopo profile has deeper, wider grooves that create a bolder, more pronounced tile look. It covers more area per sheet than step tile, which can mean slightly faster installation and fewer overlaps. Metcopo is often the preferred choice for commercial buildings, hotels, schools and homeowners wanting a distinctive roofing appearance.

In terms of durability, all three profiles offer similar performance when manufactured from the same gauge aluminium. A 0.55mm long span sheet will be just as weather-resistant as a 0.55mm step tile or Metcopo sheet. The main durability difference comes from the thickness you choose, not the profile itself. Thicker sheets of 0.55mm and above perform better in high-wind areas and coastal environments, regardless of profile.

Installation cost is another factor. Long span sheets are generally the fastest and cheapest to install because each sheet covers a larger area with fewer overlapping sections. Step tiles and Metcopo profiles require more careful alignment during installation, which can add slightly to labour costs. However, the difference is modest — usually around 10 to 15 percent more for labour compared to long span.

Our recommendation: choose long span if budget and coverage area are your main concerns. Choose step tile for mid-range residential projects where you want a premium look without premium pricing. Choose Metcopo for commercial or statement residential projects where a bold, distinctive roof profile is the goal. Whatever you decide, ensure you are getting genuine thickness by buying from a trusted manufacturer.
