New tiled and metal roofs are both long lasting and aesthetically pleasing. Generally speaking a well built roof tile roof will outlast a metal roof. Most tile manufacturers guarantee their tiles for 50 years, whereas most metal sheet manufacturers offer a 25 year warranty.
Prior to the 1960′s ‘tin’ roofs were made from soft galvanized iron that came in short lengths leaving gaps that could become leaks. The ‘tin’ roof has made a comeback and is now made from zincalume or Colorbond. It is supplied in continuous lengths to banish the horizontal gaps that could become leaks.
In the 1970′s and 1980′s the tile was the popular choice. Concrete tiles were slightly cheaper than clay or metal roofs. The traditional roof tile was considered sturdier and more robust than a metal roof. There was plenty of labour available to install tiles. Metal sheet roofs are now very affordable, durable and can be installed fast, which makes them extremely popular.
Steel roofing must be installed by a licensed plumber.Roof tilers undergo apprenticeship training to become fully qualified in their trade.
Metal roofs are often used to cover large areas because of their high strength to weight ratio.This means that you can have long, column free spans and lighter structures that use minimal framing material. The thickness of sheeting is measured as its BMT (base metal thickness). Steel with a higher BMT generally means the sheet can span further between supports. Soft or lower strength steels are generally thicker than hard, hi tensile steels. These are commonly used in applications where tight curving is required.
The most commonly used metal roofing materials are zincalume, and Colorbond. They are both available in all profiles and have a coating on the base metal. Low profile styles will increase the durability and strength of the sheeting.

Metal roofs are hail, fire and spark resistant. The different profiles are used by home owners and architects looking for a point of difference. It can be used in more situations than the traditional tile roof. When installation involves a flat roof the use of metal is the only viable option. Steel can be used in pitches from 1 degree to 90 degrees.
It is vital that the performance of the screws and rivets used to fix metal roofing have the same service life as the product used. Care must be taken with all metal roof products to avoid incompatible materials. Dissimilar materials can cause unexpected and rapid corrosion.
During severe downpours tiles absorb negligible amounts of water. This does not affect the tiles weatherproofing performance. In some climates moss and lichen can grow on tiles. They will opt affect the tiles in any way. If the clean line of the tiles is preferred they can be easily cleaned using high pressure water and a stiff broom.
Most metal roofing requires very little or no maintenance. Some metal roofs are designed to be ‘non-trafficable’, meaning that they are not designed to be walked on.

Metal roofing is very durable and has a long life. Steel doesn’t rot, split, warp twist or burn. This means that steel products can be reused without reprocessing, saving on energy and resource use. At the end of its useful life steel can be recycled. Steel is 100% recyclable and is the most recycled material in the world. Steel roofs are designed and made in such a way that they can be dissembled and reused for any number of applications. This saves the cost and energy of making new products or the costs associated with recycling products. When properly estimated there is very little waste material. Sheets can ordered and cut to exact lengths. Steel sheets can also reduce the cost and impact of transport as the more material a truck can carry to a building site the fewer the total number of deliveries.
Metal roofs offer good security. The potential burglar must come equipped with a noisy angle grinder or other tools to remove whole sheets of steel, where tiles can be easily lifted from the roof and access can be gained through the manhole into the dwelling.

It’s entirely individual choice as to what materials you choose for roofing material.Different styles and colours can create a mood or make a statement. In many cases the design determines the choice. Often people designing a new home are so focused on the house plans and the interior and exterior living areas they forget about the importance of the roof and the overall impression. The roof is possibly the single most prominent feature of a house therefore the style and material choice for the roofing can make a big difference. In the end it is a matter of personal preference and sometimes you don’t have the option of tiles.
