Installing corrugated board roofing is a popular choice for many construction projects due to its cost-effectiveness, durability and ease of installation. Profiled sheeting is corrugated metal sheets that provide high strength and weather resistance. In this article we will consider the main stages of installation of corrugated board roofing and key features that should be considered during the work.
Preparation for installation
- Design and calculation of materials:
Before starting work, it is necessary to carefully plan the location of the roof and make a calculation of the necessary amount of materials. It is important to consider the dimensions of the corrugated sheeting, the slope of the roof and the necessary fasteners.
- Surface preparation:
The surface for roofing should be flat and clean. It is necessary to remove all old roofing materials, remnants of fasteners and debris.
Installation of purlins
The purlins serve as a base for fixing corrugated board and should be made of quality materials to ensure the durability of the structure.
- Materials for purlins:
Wooden beams or metal profiles are used. The distance between them depends on the type of corrugated board and the slope of the roof.
- Installation of purlins:
Beams are fixed to the rafters at a distance that allows to securely fix the corrugated board and provide the necessary ventilation of the under-roof space.
Laying corrugated board
- Selection of corrugated board:
Select the corrugated sheeting taking into account the climatic conditions and specifics of the building. For regions with high precipitation or strong winds it is worth choosing sheets with a larger wave and thickness.
- Sheet arrangement:
Laying of corrugated sheeting starts from the bottom of the roof. The sheets are laid with an overlap, which ensures the tightness of the roof. The recommended overlap width is 10-20 cm depending on the slope of the roof.
- Fixing the sheets:
For fastening, self-tapping screws with sealing washers are used to prevent water leakage. The self-tapping screws are screwed into the lower part of the wave where the sheet is in contact with the purlins.
Sealing and insulation
- Sealing of joints:
Special attention should be paid to sealing the joints between corrugated board sheets. Use special sealing tapes or sealants.
- Roof insulation:
If the roof is planned as a residential attic, it is necessary to provide insulation. Use mineral wool or other insulation materials, placing them between the rafters.
Finishing work
- Installation of additional elements:
Install gutter systems, slip, end strips and other additional elements that protect the roof from wind and water.
- Inspection and Maintenance:
After installation is complete, inspect the quality of the sheeting and fasteners, as well as the tightness of the joints. Regular roof maintenance, such as cleaning the gutters and checking the condition of the fasteners, will prolong the life of the structure.
Installation of corrugated board roofing - a process that requires attention to detail and careful execution of technological steps. Compliance with recommendations for the preparation, laying and fastening of materials will ensure the reliability and durability of the roof. Due to its characteristics corrugated board is becoming increasingly popular material for roofs of various types of buildings, from residential houses to industrial buildings.
