Why is a tin roof better

The tin roof and its use on different roof shapes

For certain buildings, such as garages, it makes sense to think about alternatives to the usual roof tiles as roof cladding. A sheet metal roof has advantages over roofs that have been covered with other materials. You can find the most important information on the subject of sheet metal roofs and what must be observed here at Dachdecker.com.

There are various forms of roofs, from the conical roof to the gable roof to the half-hip roof, all of which have their own special properties and functions. In principle, the roof shapes mentioned, as well as all others, could be covered with sheet metal. Usually, however, sheet metal, i.e. thinly rolled metal, is often only used for certain roof shapes, mainly for flat roofs or when building a pent roof. For a long time there were, or rather had been, very good reasons. Because rain can cause noise on sheet metal, the complete impermeability to water can lead to dangerous mold formation underneath, it can get very cold in winter and very hot in summer. But this is now only true to a very limited extent or not at all. Because with new technology, better insulation and the right processing, a sheet metal roof can help save costs and still represent an equivalent alternative to roofs made from other materials.

The substructure of a sheet metal roof

Decisive for the quality of sheet metal roofs is not only the sheet metal itself, but essentially the substructure and insulation. The sheet metal itself is available in different profiles, which in turn give the roof different properties. The stability of a roof made of sheet metal is mainly determined by the substructure. A solid roof covered with sheet metal is fundamentally more stable than a rafter roof, for example. With a rafter roof, factors such as the distance between the rafters, the thickness of the sheet metal and its profile also determine the stability of the roof.

The insulation of a tin roof

A roof made of sheet metal not only needs to be insulated to keep out heat or cold, but also for noise protection reasons. There are metal sheets that are already coated to protect against noise and in which insulation is also integrated, which may make extra insulation, for example with mineral wool, superfluous. However, it also depends on the use of the space below the roof how complex the insulation should be. For example, it can be relatively irrelevant for a garage how loud you can hear the rain and how cold or warm it gets. Other things play a role here in terms of insulation, such as fire protection.

The right slope of a tin roof

There are different views on the optimal slope of different roofs, but it can be assumed that a greater slope tends to have certain advantages for the durability of the sheet metal roof. A minimum slope of three percent should not be undercut under any circumstances; a slope of five percent would be safer, for the simple reason that standing water can attack the surface over the long term and thus permanently damage it. This then has a negative effect on the shelf life, which otherwise can be around 40 years. Since the sheet metal is impermeable to air and water, special attention must be paid to good ventilation of the wooden substructure. For this reason, sheet metal roofs are usually constructed as cold roofs.

A tin roof is an alternative to the classic tiled roof, especially on garages or warehouses! Basically, it can be built on any roof shape or type, but there are special requirements for the insulation - on the one hand for noise reasons, on the other hand due to the high risk of mold. A major advantage of such a roof is its durability! Let a roofer advise you on further advantages and disadvantages as well as the costs incurred!
