Whilst everyone recognises a roof once it has been built, not many people know exactly what roofing materials go into the construction of a standard roof structure. In this article, therefore, we set out what your roofers in Torquay, Newton Abbot and Devon use when they construct your new roof to protect your home, your contents and you from the elements!
The principal part of the structure of any roof is the roof truss. This forms the skeleton of the roof, consisting of an interconnecting framework of wooden beams whose job is to provide support for and stability to the roof.
Forming part of the structure of the roof truss, the rafters are roof beams that run from the top of the roof to the bottom.
Dormers, which can be present either on the walls of a house or the roof, are constructed, in the case of the latter, around any window that projects from a sloping roof. The dormer is insulated against moisture and wind to ensure that its existence does not cause a breach in the room’s protective capability.
Decking or Sheathing
Decking or sheathing are coverings that are placed on the rafters of the house. Their purpose is for the attachment of roofing materials such as shingles and other types of paneling.
The Roof Valley
The roof valley is the internal angle that exists in the spot where two sloping roofs interconnect. It is essential that the valley is properly waterproofed and kept clean to ensure that any unnecessary water penetration is avoided.
As its name probably reveals, the ridge constitutes the highest point of the roof. The ridge, which is normally protected by its own individual ridge tiles, runs along the entire length of the roof.
In order to provide an extra layer of protection against water infiltration, underlay, which is in the form of either a hard-wearing felt paper (which is sometimes known as tar paper) or other man-made materials may be attached to the the surface of the decking or sheathing.
The Drip Edge
In order to prevent water from running from the roof down the walls of a house and thereby raising the risk of penetrating damp, the drip edge is positioned above the end of the eaves of the roof’s structure. The edging permits the water to run away from and drip clear of the walls.
As we have described in an earlier article, the fascias are located where the gutters are attached to the property. Usually made of wood or metal, the fascia runs horizontally directly beneath the lower section of the roof.
The soffits are the structural components that bridge the gap that exists between the top of the external walls of a house to the eaves of the roof.
Once again as described in a previous article, flashings are pieces of metal, which is frequently lead, whose purpose is to guard against water infiltration through the joints that occur when certain structures are added to the roof. The type of structure that is kept insulated by the employment of flashings are chimneys, vent pipes and dormer windows. Flashings also protect the valleys and the joints between verticle walls.
In summary, these are the main components of the standard roof construction. Putting all of these pieces together properly is not as easy as describing them, however! Anyone who needs a new roof to be built in and around Devon and the South West should contact a team of professional roofers to ensure that the job of keeping a roof over their heads is done properly!
