If you want to install roof battens, this guide will help you. First, determine the height of your rafters and then measure from that point. Then, use a set square to mark a line on the battens. Then, using a power saw, cut them along this line. Be sure that the battens are even in height. When installing battens in a pitched roof, you will need to use battens that are at least one inch higher than the rafters.
Once you have determined the height and length of the rafters, you can fix the underlay and tile battens to them. You should always choose underlay material that complies with the requirements of BS 5534 for wind uplift resistance. After fixing the underlay, you should secure it with a felt nail. Make sure that you use extra-large head nails, 3.35 mm in shank diameter, and 20 mm long.
The ideal orientation and spacing of battens depend on the type of roof and the environmental conditions. Sometimes, battens are oriented at right angles to trusses or parallel to the slope of the roof. Other times, they may be placed parallel to each other, which is known as a counter-batten system. Ultimately, the type of roof you have will determine the best batten installation. Some flat roofs may not require battens, while steeper roofs may require them.
A roof batten installation guide will also help you choose the correct spacing between battens and tile. It is important to follow the recommended distances between battens and tiles so that the top course of tiles overlap the first course by approximately 75mm. If you want to tile your roof without using battens, you may need to make additional courses. The distance between battens and tiles should be somewhere in between the minimum and maximum requirements.
After selecting the correct spacing, you must take measurements. First, you must measure the length of your tiles and the height of the eaves. Once you have all the measurements, you can start planning your roofing project. If you are doing it yourself, you might find that calculating the correct spacing is easy and quick. In the end, roof battens play a crucial role in the rigidity, durability, and weather-tightness of a roof. To measure battens and their spacing, follow BS 5534–2014.
In addition to battens, a roof batten installation guide will explain how to attach counter battens, a layer of timber that is 25mm to 50mm thick. Counter battens are generally placed on roofs that have insulation at the rafter level. The placement of counter battens will depend on the direction of airflow and the type of underlay, so be sure to check this before installing them.
