This is a YouTube video titled "What are Elevated Battens, and why are they useful?" containing an explanation about tile roofing installation techniques, specifically focusing on the benefits of using elevated battens for improved air circulation and water shedding to extend roof lifespan. The content is presented by a single speaker providing technical information about roofing.
Tile roofing is installed by attaching a concrete tile to a wooden batten via a nail. Whether you have S tile or flat tile, the batten is still used in the same fashion. Traditional battens sit flush to the decking. This creates a couple of issues on the long term. The first issue is flush to decking does not allow air to pass through there. Now if we opt for an upgraded elevated batten this allow air air to rise in from underneath the roof and escape through the top portion called the ridge. This means that we can take hot air from the attic and help it escape through your rooftop. The second big benefit of an elevated batten is water shedding. Now these roof tiles are not waterproof. They do allow some water in that is then protected by your underlayment. However, when water goes to a flush batten it then has to try to find a way around that batten and that damming can sometimes lead to leaks. With an elevated batten that water sheds right off the roof, no damming and helps extend the lifespan of your roof.
