Building a new roof requires a high level of skill and expertise and should be left to a professional builder. However, there is no reason why minor repairs should not be attempted, therefore knowledge of roof construction and the components will be useful.

Building a new roof requires a high level of skill and expertise and should be left to a professional builder. However, there is no reason why minor repairs should not be attempted, therefore knowledge of roof construction and the components will be useful.

Basically there are five main components in roofing:

  • Timber framework
  • Felt underlay
  • Timber battens
  • Roof covering
  • Flashing

Timber structures

Most houses have a pitched roof structure with a timber framework. The four main types of roof structure are Gabled, Hipped, Mono-pitched and Mansard.

A gabled roof has two pitched planes that slope around triangular extensions of the end walls. The triangular extension is the gable.

A simple hipped roof will have four sloping planes. The hip is the joint between two adjacent slopes. Some roofs are extremely complex with numerous hips. 

A mono-pitched roof has only one slope and is commonly found on extensions.

A mansard roof comprises of two planes sloping at different angles on each side of the building. Mansard roofs create a spacious living area in the roof space.

Straps and plates

Metal straps and plates are used in timber roof construction to securely hold rafters, joists and struts together. The straightforward way in which straps and plates are fixed to the timber eliminates the need to cut complicated joints, thus speeding up the construction.

Restraint strap

Straps come in various designs and are used to secure roof timbers to walls. The L-shaped restraint strap fixes to the end of a rafter and is then attached to a gable wall.

Timber connector

A timber connector is a rectangular metal plate perforated with small fixing holes for screws. These are used where roof timbers join together.

Truss clip

Truss clips are used to connect the ends of roof joists to the wall plate which is the timber beam that runs across the top of the wall.

Heavy-duty truss clip

A heavy-duty truss clip is more robust than an ordinary truss clip and has a deeper recess to accommodate wider joists.

Roofing felt

Roofing felt is laid beneath the tiles to create a waterproof barrier. It can be laid directly over the rafters in horizontal strips with the edges of each strip overlapping. Alternatively, timber sheathing can be fixed to the rafters and then the roof felt laid over the ply.

Timber sheathing is usually sheets of plywood. It is laid across the rafters, staggering the joints as you move up towards the ridge. To fix the sheathing in position nail the sheets of plywood to the rafters using a fixing every 150mm (6in). To improve ventilation in the roof space gaps are sometimes left between the sheathing, as you get closer to the ridge. Sheathing is generally used when the roof has only a slight pitch, but in some areas the Building Regulations make it a requirement. If you are making a repair...
