How to felt and batten a roof uk.

Where wind driven rain is working under the roof and causing leaks then the felt will need to be replaced. To replace a small section of roofing felt involves stripping the tiles from the roof and replacing felt between two joists. A slight sag between rafters is ideal as it will allow any water to drain down the felt. Eventually i was in a position to lay felt and batten out the roofs.

Underlay is generally held in place by the tile battens but where nailing is required nails should be extra large head felt nails of 3 35 mm shank diameter and 20 mm long. This would be a big step to being properly waterproof. When the first length is complete lay the next layer of felt on top of the first so that it overlaps by at least 100mm 4 inches horizontal overlaps where one roll ends and the next one is started should be at least 150mm 6 inches. I had been using tarpaulins over the trusses but they can only do so good a job and when the wind blows the damn things rustle like mad the rain then finds its own lovely little route to somewhere you don t want it.

Work along the roof taking out any excess slack in the felt but do not pull it tight.
