When we talk of metal roofs, most of the people think of roofs made of metal panels which are joined together by joints or raised seams. This is often not the case as there are several numbers of obtainable metal roofing products.

Ceramic Tiles

Another popular choice of roofing material is ceramic. Clay tiles are incombustible and fairly sturdy, necessitating scarcer repairs or substitutions than asphalt roofs.

Concrete Tiles

For those that like the look of ceramic tiles, as well as their fire resistance, this may not be the choice, but those who want something a little tougher and less susceptible to cracking when having work done on the roof, there are the best tiles.

Bituminous Tiles

For those that want a lightweight, supple tile that’s easier to fit, there’s the bituminous tile. These types of tiles are made from cellulose fibre or using fibreglass allowing them to be flexible.

Polymer-Sand Tiles

A new-fangled substitute for ceramic tiles is the polymer-sand tile. Created from a combination of sand bound together with polymers, these are very rigid, sturdy tiles are shaped in a mould.

Copper Tile

Copper roofs can be a great choice for many due to their long lifespan. Copper tiles have the ability to last over a century before needing replacement.

Composite Tile

Another newer roofing tile is the composite. This is a multi-layered tile that is made using metal, acrylic and stone granules.

Stone Tiles

This is one of the oldest forms of roofing tiles that you can get out there. It is also one of the longest-lasting tiles on the market as well, with some roofs lasting well over 100 years.

A pitched roof is a type of roof that is defined to have a sloping surface that has an angle that is greater than 20 degrees. Pitched roofs offer a more classical appearance. They remain the most communal and effective answer in wet and cold weathers to guarantee all-out protection.

Eaves

In the roof, the lower part of the inclined roof which is prominent outside the external face of the wall. The chief purpose of eaves is to pour the rainwater from the roof straight on the exterior wall. It also provides protection from sunlight. Eaves are sometimes decorated to an architectural beauty.

Gable

The Three-sided higher part of the wall at the end of a ridge roof.

Flashing

A band of impermeable material, typically metal, used to eliminate water from the intersection between a roof covering and another part of the structure. Flashings are provided to stop moisture from inflowing the wall and roof through joints in copings, parapet wall, and other infiltrations through the roof plane.

Hip

The Hip is defined as the exterior angle, which is generally greater than 180 degrees, which is formed at the inclined ridge of the roof slopes.

Ridge

The ridge is defined as the horizontal intersection made by the rising roof surfaces that are inclined in opposite directions.

Purlins

Purlins are the horizontal members which are laid on the principal rafters which help to support the common rafter of a roof. This is usually done when the span is large. Purlins are made from wood or steel. The top surfaces of the purlins intend to be unvarying and plane.

Fascia

This is the wooden board that is fixed to the feet of the common rafter at eaves. The Fascia helps the lowest ends of the roof covering material to rest on it.

Rafter

One of the major structural components of a pitched roof is a rafter. The rafter generally begins for the support of the roof to the ridge or hip. The purlin is supported by equally spaced rafters used side by side.

The task of installing a tile roof can be quite a difficult one. Such a project takes a great deal of preparation, well before the actual tile installation is done. It does not matter if you are putting new ones or replacing your old tiles, understanding the proper technique and steps become crucial.

Remove old roofing (if applicable).

This is, on its own, a major job that can take days and require special tools. It takes some time, but be prepared to do it right.

Install battens (if applicable).

Battens may be needed to hold the tiles in place if the roof is having a steep slope. Usually made of metal or wood, battens are generally 1 inch thick and run horizontally along the roof.

You can find several varieties of tiles that has a hook or a lip allowing it to hang on the available battens. Apart from this, you can find several clips in the market which help to attach the tiles on to the batten.

Determining the spacing for battens can be done easily using two tiles. To prevent interlocking, a three inch overlap is required at the minimum, and a smaller amount of overhang should be left over the eaves. Keep this in mind when you determine the locations of the battens.

After you have determined the distance between the first two battens, measure the distance and set battens using that spacing up, making sure to double-check measurements as you go along.

• Install the tiles.

• You will need to begin with one side first, and then continue to move along the length of the roof.

• Cut tiles to fit tight spots.

• Tiles have to be cut precisely to overcome any obstacle like the chimney.

• Install the ridge tiles.

After completing the broad surfaces of the roof, special ridge tiles are required to cap the top.
