Roof shingles made of sheet metal are not real shingles

Sheet metal as a covering material on a roof is an interesting alternative to the common pans, wooden and brick shingles or bitumen shingles. However, sheet metal roof shingles are almost never used as individual elements. Prefabricated sheet metal plates bring the shingle look incorporated by pressing and punching with them.

Sheet metal profiles with imitation shingles

Anyone who decides today to cover a roof with sheet metal can model a house as well as a garden shed and use pre-formed sheet metal sheets with a shingle structure.

The sheets can be applied and assembled on the rafters in a fraction of the time required for individual shingles. An average sixty square meter roof can be covered in one morning. Thanks to the fastening technology of riveting, up to five square meters of roof area can be covered in one operation.

Structural challenge condensation

A sheet metal roof has two properties that must be addressed. Since the sheet metal panels are not real shingles, there are no joints or overlaps. An airtight cover is created. In unfavorable conditions under the tin roof, this can cause condensation problems. This phenomenon must be countered structurally with rear ventilation.

Since sheet metal is an extremely thin material, a cavity can easily be created in the substructure through which air can circulate. It serves as a buffer so that the warm air rising from below does not suddenly cool down on the underside of the tin roof, which triggers condensation.

Structural challenge of rain noises

When rain and hail pelts sheet metal, a high level of noise can arise. This effect is countered structurally with decoupling. The sheet metal plates must not be able to vibrate and thus form a membrane.

Correct attachment to each fixing point also prevents strong winds from generating noise. Professional and correct installation will never make a tin roof as quiet as a bitumen or tile roof, but the noise can be limited to a moderate volume.

Tips & Tricks Nowadays you get roofing sheets with a shingle look, which from a distance are almost indistinguishable from tiled roofs. You also have a large selection of shingle shapes.
