Roofline Fascia & Guttering
Roofline is the section at the edge of your roof where the wall and the tiles meet
Here you will find the vertical fascia board, which carries the guttering, and the horizontal soffit board. At the gable end of a house, where the roof rises up to a point, the bargeboard takes over from the fascia board.
The point at which the fascia and bargeboards meet is referred to as the box end.
Building regulations require the roof void to be ventilated in order to prevent a build up of condensation which could result in damage from rot.
Ventilation can be provided through the soffit board or over the top of the fascia. Swish supplies a range of components to achieve either option.
Over Fascia Ventilation
The ventilator unit sits on top of the fascia board and is hidden by the guttering system. This means that the soffit is left plain without ventilation slots in it, which is a look preferred by some owners. It is not always possible to fit these units if the fascia is to be over capped.
Through Soffit Ventilation
This is the traditional method of providing ventilation. Installers usually use slotted (Swish Polo) boards. However, where the original soffit is being retained and overcapped, circular ventilators will have to be fitted to provide a clear air path through both boards
No salespeople, no high pressure, you choose.
