A metal roof is characterized by its resistance to damage and low level of maintenance. Metal roofs are primarily designed as “cold” roofs. On a wooden formwork, under which the rear ventilation is arranged, the sheet is mounted in tracks. Depending on the manufacturer’s instructions, a separating layer is first applied to the wooden formwork, after which the metal sheets are attached.
It is necessary to arrange snow rakes to prevent snow from falling into the gutter during winter and damaging the roof. These generally consist of horizontally arranged metal tubes that are mounted on the vertical rebates. Metal roofs can be discovered not only on factory buildings or churches but increasingly on residential buildings.
Metal can be used to decorate the most unusual types of roof shapes. Various forms, as well as the high malleability of metal sheets, open a variety of creative possibilities. A distinction is made between self-supporting and non-self-supporting metal roofs.
Self-supporting metal roofs are mounted on slats or purlins and, thus, connected to each other by folds. In contrast, a closed formwork is necessary as a substructure, especially if it is a non-self-supporting metal roof. There are many metal shingle options to choose from, so make sure each option is considered.
The main advantage of a metal roof is its resistance to the elements. Roofs with a shallow slope should be additionally waterproofed. Also, a metal roof is mostly unresponsive to environmental influences and pollution and, therefore, is virtually maintenance-free.
- Lightning-fast installation. A metal roof can be installed quickly. After all, with every single step, the roofer can cover several feet at once.
- Perfect density. Metal roofing is at least as dense as a roof made of tile or slate.
- Individual design. Thanks to the numerous types of metal, forms, and metal colors, unique design forms for metal roofs have no limits.
- Storm-tested. Unlike shingled roofing, wind and storms cannot easily damage metal roofs, which makes a metal roof particularly suitable for storm-prone areas.
Lastly, the environmental impact is massive. Regarding environmental friendliness, metal roofs are a plus because they are 100% recyclable.
