The roof should be durable, strong, resistant to moisture and external factors, and at the same time aesthetically pleasing. Therefore, sophisticated materials with specific properties are used in its preparation, such as ceramic products, concrete or tin roof tiles. Today we will take a look at the latter and examine why sheet metal is one of the most common covering materials.
Tile, or sheet metal roofing
Covering elements are most often manufactured from specially shaped steel sheet. In order to protect its surface, the raw material undergoes double-sided galvanization and several stages of varnishing. Thanks to a special embossing process, the covering quite closely imitates traditional clay tiles. Therefore, the product is often used as a substitute for more expensive coverage components. Depending on a number of factors, the components may exhibit different durability. The thickness of the steel core is crucial here, as well as the type and thickness of the protective coating. It is it that protects the inner sheet metal from the effects of corrosion, ultraviolet radiation or moisture. There is also a special type of coverage, known as a “cover. sheet metal with sprinkles. The profiled element in this case is coated with an additional layer of resin, over which a mineral or ceramic sprinkle is sprayed. The surface is then protected with acrylic paint. This type of roofing is characterized by much higher resistance than standard sheet metal tiles.
Sheet metal roofing – when can it be used?
This method of roofing is often chosen for steep roofs with slopes greater than 9 degrees. Mineral sprinkled tile requires an even higher pitch angle – suitable for laying at a minimum 12-degree slope. The product is distinguished by its relatively low weight, which averages 5kg per square meter. Compared to heavy ceramic components, this is a considerable advantage for cheaper steel products. Low weight means greater ease during installation and the ability to apply the covering without reinforcing the roof trusses.
Sheet metal has quite a few advantages….
Sheet metal roofing carries a number of benefits. First of all, as already mentioned, the components have a relatively low weight, which translates into ease of installation and the possibility of reducing costs. Despite this design, the sheet metal is characterized by high resistance to damage and durability. And thanks to the galvanized and varnished layer, moisture access to the inner structure of the element is greatly impeded. Another advantage is the low installation costs that go hand in hand. Covering the roof with tile is a much cheaper way than using ceramic products. This is primarily due to the way the elements are prepared – tin roof tiles are simply stamped in special molds, while ceramic products require much more labor. Sheet metal is also a type of universal roofing. The covering will work well for both covering older houses and new buildings. The angle of pitch is also irrelevant here – the material lays perfectly on a roof with a high pitch. So the product is great for areas where heavy snowstorms occur very often.
A product without defects? Not really…
The downside of sheet metal is that it is not suitable for covering a roof of complex construction. Varying the shape of the surface can make it much more difficult, or completely impossible, to prepare the roofing, because in this case wide sections of sheet metal must simply be cut. This can result in increased costs due to the large amount of material waste. Improper acoustics in sheet-covered apartments can also be a problem. It generates audible and, for some, annoying sounds when exposed to the weather. Admittedly, there are ways to reduce this inconvenience…. One of them is to place a layer of special film to dampen unwanted sounds. However, this requires additional activities and more work. Tile is also a less durable product than ceramic roofing. This is not just a matter of steel’s susceptibility to corrosion, but faster wear of the protective layer. It is worth remembering that the material expands and contracts when exposed to temperature, which can cause weakening and damage to the
protective layer. Therefore, roof repainting is much more common with this covering.
