The difference between the folded roof covering and the CLICK roof covering lies mainly in the method of installation and aesthetic properties:

Roof covering KJG FALZ (classic folded roofing) is a traditional type of sheet metal covering, where individual sheets are connected by the so-called double fold (bend). This method of installation requires experts, because folding is done by hand or using special machines. The folded roof covering is very resistant to weather conditions, also suitable for roofs with a very low slope, and it has a classic, elegant look.

Roof covering KJG CLICK system is a modern type of roof covering which is installed easier thanks to the so-called CLICK system. This system allows you to click individual sheets into each other without the need for manual folding. The installation is quicker and manageable even without special equipment. The roof covering CLICK has a clean and modern look, but it is not always as resistant to extreme conditions as classic folded roofing.

You can find all types of snow catchers in the section Products under the category Snow catchers. They are divided according to the type of roof covering, which will make it easier for you to choose the right catcher for the KJG roofing.

When installing KJG roof coverings, it is important to take into account temperature conditions, because low temperatures can affect the properties of materials and the quality of work.

In general, it is recommended to carry out the installation of sheet metal roofing at temperatures above +5 °C.

At lower temperatures, increased material fragility may occur, increasing the risk of damage during installation.

In addition, at temperatures below the freezing point, there may be problems with sealing and applying sealants that may not adhere or cure properly.

We offer standard flashing which we have in stock and also custom flashing which we can make exactly according to your requirements and technical specifications.
