What Is A Roof Battens?
Roof battens are thin strips of wood, plastic, or metal that are installed before tiles are placed on the roof. They have multiple purposes, such as fastening tiles, elevating tiles off the roof deck to ensure drainage, and creating a thermal barrier for energy savings.
The ideal installation method depends on the roof’s slope, material, and environmental conditions. On steeper roofs or in cold climates, tiles are often fastened to battens to prevent them from lifting. In regions with high winds, tiles are also fastened to battens to prevent them from lifting.
The way the battens are installed can also affect drainage efficiency. Horizontal battens perpendicular to the slope of the roof may trap moisture and need gaps for drainage, while vertical battens, also known as counter-batten systems, provide space for drainage and can help extend the life of the underlayment.
The purpose of roofing battens is multifaceted in a roof structure. They serve as a base for attaching roof tiles, bear the load of the tiles, and assist in sustaining the pressure of snow and wind. They can also be used as a step during installation, but only when placed directly over a rafter.
Given the crucial role they play, it is vital to carefully choose the right product and adhere to industry standards to ensure the longevity of the roof. This guide aims to aid in understanding the necessary specifications and identifying distinctions between products.
Installation Of Battens
When installing roof battens, it is important to take your time and make sure you are following the manufacturer’s instructions accurately.
Before starting, ensure that the roofing surface is properly prepared for installation – this includes checking for any signs of water or air infiltration. It’s important to use high quality fasteners and adhesives when installing battens on the roof.
The orientation and spacing of battens for a roof vary based on the design and environmental factors it will encounter. They can be perpendicular or parallel to the trusses or rafters and may require a combination of both orientations in some cases.
The slope of the roof is a determining factor for the type of batten system used, with flatter roofs not requiring them unless there is heavy rainfall, while steeper roofs may have specific installation requirements dictated by local building codes.
Benefits Of Using Battens
Roof battens are a crucial but often overlooked aspect of home construction. They play important roles in protecting the roof by providing ventilation, strengthening the structural performance of the roof truss, securely attaching roofing materials, and aligning roofing sheets.
The material and design of the battens are critical as they distribute forces such as wind and weight across the roof.
Inadequate fasteners or inappropriate batten materials can lead to roof failure, making it important to consult with experts when replacing or designing a new roof.
Types Of Roof Batten Systems
Roof battens can be made of various materials such as metal, wood, plastic or composite. Some types of battens combine two materials to achieve a specific effect.
For instance, elevated battens are traditional wood battens that have a plastic or wood block attached to the bottom to raise the batten to a specific height. These are commonly used with tile roofs to increase energy efficiency, allow airflow and prevent heat transfer into the attic.
They are more expensive than other types of battens. Traditional wood battens are typically 1″x2″x4″ and made of hardwood while metal battens are used with metal roof panels. Plastic battens are not as commonly used as other types.
