One of the important issues in roof covering execution is the proper collection and directing of rainwater. It is a prefabricated channel made of galvanized sheet or aluminum that is installed at the end of the roof slope, directing water from rain and snow to the drainage point. These structures, along with flashing, ensure the complete sealing of sandwich panel and Zip Panel roofs. Due to their easy installation, suitable weight, and variety in dimensions and thickness, gutters can be used in any type of structure.
The installation of reliable gutters in sheds and multi-span structures is of critical importance. If the drainage system is not executed correctly, water will accumulate on the roof and can:
* Increase the roof’s weight dangerously
* Damage the roof covering
* Cause moisture penetration into the structure
This issue is of even greater importance in high-rainfall regions of the country, such as Gilan, Mazandaran, and Azerbaijan.

Roof gutters are classified into three main categories based on shape, material, and application:
London gutters are made from bent galvanized sheet or aluminum. The thickness of the galvanized sheet is 0.5 mm and aluminum ranges from 0.7 to 0.9 mm. Connections are made using screws and rivets, edge pressing, or welding.
The use of galvanized sheet provides high resistance against corrosion. This type of gutter is manufactured according to European standards and offers fast and easy installation.
It has a more aesthetically pleasing and modern appearance compared to the London type and is primarily used for the sloped roofs of restaurants and residential structures. The thickness of this profile exceeds 0.4 mm, and it has partially addressed the rusting issues associated with the London type. When using space frame structures, connection points must be sealed with welding, and the spacing of the support straps is determined based on the thickness of the gutter.
This type of gutter is installed between the ridges of sloped roofs and directs rainwater or snow from the intersection points of two surfaces. Its standard dimensions are 2 meters in length and 50 cm in width, with a thickness of 0.4 to 0.5 mm.
In some projects, custom gutters are designed to suit the specific site conditions. In this design process, factors such as the regional climate, roof area, and building shape are considered to determine the appropriate material, form, and thickness.
To prevent detachment and cover sensitive roof areas, covering sheets called flashing are used. Alongside the gutter, flashing ensures complete waterproofing of the roof system.
– Ease of installation and execution
– Lightweight
– Enhanced aesthetics
– Noise-free
– No need for longitudinal slope
– Improved waterproofing and higher load-bearing capacity
– Capability to accommodate multiple outlets.
In standing seam roofing systems, the gutter diverts rainwater away from sensitive areas and prevents moisture penetration. The installation method varies based on the material:
– 2 mm Aluminum Gutter: TIG Welding
– 2 mm Galvanized Gutter: MIG Welding
– 0.6 mm Galvanized Gutter: Screws and Rivets
In cold regions, installing a heating cable inside the gutter is recommended. The heater helps melt snow quickly and prevents gutter blockage during winter.
– Snow-Melting Heater Sheet
London gutters are more suitable for industrial structures and warehouses. Box gutters offer a more aesthetic appearance, making them a better choice for residential and commercial projects.
In regions where winter temperatures drop below freezing, installing a heating cable inside the gutter is highly recommended to prevent water freezing and damage to the system.
The selection of thickness depends on the roof area and the region’s rainfall intensity. For large industrial roofs, a 2 mm thickness with welding is recommended.
The gutter is one of the essential components of any sloped roof cladding. Choosing the right type (London, Box, or Valley) is determined based on the building’s usage, climate conditions, and project aesthetics.
