Most often used as a roofing solution in commercial and industrial projects, metal tiles can also be seen on some residential roofs.
However, because of their characteristics, metal shingles may not be the most suitable solution for those looking for safe, durable and cost-effective residential coverage.

Types of Metal Tiles
- Conventional corrugated
Available in the market with thicknesses ranging from 0.4 to 0.7 mm, conventional corrugated metal tile is most often used in small roofs with smaller spans.
Occasionally, the material can be used for arched roofs, but in this case, they require special attention to ensure the safety of the work and the durability of the roof.
One of the biggest disadvantages of this type of material is related to the lack of acoustic comfort. As smaller spaces generally do not have sound insulation, noise on days of heavy rain or hail can be quite uncomfortable.
Another disadvantage of this type of tile is its low durability, as the material is subject to kneading, which can lead to constant maintenance. In addition, the finishes used in the assembly of the metal structure can also rust if not specially treated, which increases the total cost of the project.
- Conventional trapezoidal
One of the most common metal roof tile models, trapezoidal conventional tile is most often used in commercial and industrial buildings, although it can be seen in residential real estate.
Available in the market in a wide range of dimensions and thicknesses, conventional trapezoidal metal tile can also be used for side closures of industrial designs.
Additionally, this type of metal tiles can be obtained in factory painted versions, which increases its resistance to both ultraviolet and weathering action, as well as offering better aesthetic performance.
In addition, both trapezoidal and corrugated tile can undergo a galvanizing or zinc plating process to protect the material from corrosion.
One of the biggest disadvantages of this type of tile is that, because it is heavier, it requires a more robust structure to support its weight, which increases construction costs.
- Trapezoidal self-supporting
This tile model is most commonly used in large-span constructions, as it does not require a metal frame along these spaces.
Due to these characteristics, trapezoidal self-supporting metal tiles are most commonly used in large buildings such as industries, warehouses, and distribution centers.
Although it is easy to install, the thin thickness of this type of metal tile makes the material more subject to the instability of various natures, which reduces the safety of the project and can increase the maintenance costs of the roof.
The lining metal tile is so named because it is made up of three layers – one of trapezoidal metal tiles, one of polyurethane foam injections and a third of PVC coating – which makes it look similar to that of a lining.
This is also the reason why this type of material offers good thermal and acoustic comfort but has less resistance than other tile models, which increases the chances of deformation and, consequently, leakage and infiltration.
- Thermoacoustic Tile or sandwich
Quite similar to the ceiling tile, as it also has three layers, the thermoacoustic tile, also called sandwich tile, has an expanded polystyrene (EPS) layer that is pressed between two other layers of metallic trapezoidal tile.
While offering good thermal and acoustic comfort, sandwich tile requires a high investment compared to other roof covering solutions.
- Zipped Metal Tiles
Zippered metal tiles have as their main feature the large dimensions – it is possible to find, for example, single pieces of 60 or up to 120 m in length – with a mechanical seam between the profiles, which allows the continuous installation without the use of fasteners, such as screws and connecting tapes.
For this reason, they are most often used in large roofs with low inclination. However, due to their dimensions, they require considerable space on the site to be profiled. In addition, they increase labor costs, as the handling and installation of parts of this size require a larger staff.
- Roll-on Metallic Tiles
In this type of roofing, coils of metal shingles are used. Along with that, zincalume, galvanized or pre-painted are unrolled over a set of trusses. This roofing solution reduces the chances of leaks and leaks, as the tiles have the full length of the design and do not need seams, holes, and overlaps.
Due to its specific characteristics and the high cost of the material, this option is not usually used in large buildings such as shopping malls, industries, and distribution warehouses.
