Different Types of Metal Roofs in Australia
Recently I sat down with a client who is in the roofing trade in Brisbane Pro Build Roofing, we have been working on strategies to build a better customer experience. I was curious about the industry and we got to talking for hours about metal roofing. I thought it would make an interesting article. Here we share some information on the different kinds of metal roofs in Australia.
Metal roofs are made from tiles or one large flat sheet of metal material. They can be seen on many modernized homes throughout Australia.
For a thousand years copper has played a big role in construction and the architecture of roofs and homes. Copper roof shingles were established in the 3rd century B.C. where they were placed on top of the roof of the Loha Maha Paya Temple that is in Sri Lanka. Copper was also used in Roman times for the Pantheon in 27 B.C. and into European medieval culture. Another of the first metal roofs is the Hildesheim Cathedral which still stands today. The Renaissance castle of Kronborg is also equipped with copper and was renovated in 2009. In the earlier times metal roofing was formulated with large sheets made of galvanized steel.
Advantages and Disadvantages of Metal Roofing in Australia
The main advantage of metal roofing in Australia is the use of recycled material. Some of the disadvantages are the roofs can rust, metal thief’s look for these types of materials and the reception to electronic device is corrupted sometimes with metal roofing. The location you live can determine which kind of metal is best for your home. My client has a Queensland based roofing company www.probuildroofing.com.au and he recommends Colorbond roofing as a great material to choose for homes. It has many advantages and has become one of the most popular choices for home owners throughout Brisbane, Sydney and Melbourne.
Material Makeup of Metal Roofing in Australia
There are numerous materials of roofing in Australia. These include:
- Blends of zinc, silicon steel and aluminum. These types of materials can be known as galalume and Zincalume.
- Metal sheets of tile. These can be stone coated or painted.
- Corrugated galvanized steel. These materials were used in the past and with the economy focusing on living green they have started to make appearances again.
- Copper. Copper is the main metal used in roofing throughout history. It is used because of all the advantages including long life spans, shielding of radiofrequency, protection from lightning, benefits of sustainability, durability, corrosion resistance and the low maintenance they need.
- Stainless steel. Can be used as shingles or long rolls of sheets.
- Stone coated steel. Natural product of stones with a colored coating made of ceramic. These types of roofing materials are made from acrylic coated steel of aluminum and zinc.
- Aluminum. Known as having one of the longest life spans of all the materials used for metal roofing lasting well over 50 years in most instances. They offer protection from corrosion and are light in weight.
- Lead. Lead is mainly used in porches and over hangs.
Coating on metal roofing
There are several different products that all metal roofs in Australia are coated with. Coating on metal roofing can help for life spans of the product and other functions as well. Due to the weather conditions in Australia, primarily the heat, coating metal roofing helps to reflect the heat generated from the sun. They can be coatings of:
- Clear coating. This is applied to copper to help with the reflection of the sun and to avoid the buildup of moisture which in turn can jeopardize the roofing. These coatings are often a combination of materials including Lemon grass oil; paraffin oils Native E.I., linseed oil, Castor oil and Lemon oil. These coatings are normally repeated every 3 to 5 years.
- Ceramic coating. This type of coating helps to reflect heat as well due to the Australian sub tropical weather. The color used is normally white that is in a matte finish.
Most Frequently Used Metal Roofing
There are some types of roofing that are the most common in Australia. These include:
- Copper Roofs. Has been used since the early 18th century
- Galvanized steel. This was the metal of choice in the history of Australia but has become less used compared to zinc and aluminum coated steel. It can however still be seen on many older homes.
- Stone coated metal roofs
- Flat seam metal that can be with or without soldered seaming
- Standing seam roofs of metal that have concealed fasteners
- Concealed fasteners on mechanically seamed metal. This is primarily used for roofing that has very large scopes.
The type of roofing has been evolving over the centuries. Australia has adapted and come up with different types of roofing. The main concern with metal roofing in Australia is the ability to reflect light from it because of the temperatures being able to reach so high during certain times of the year. There are tons of companies that can install and repair metal roofing throughout the country as well. Metal roofing has become popular this century because of its ability to be close to maintenance free, be fire resistance and be durable. These types of roofs are also heat resistant and energy efficient as well. Studies have shown that metal roofing can absorb close to 34% less heat than other materials including asphalt shingles. People who have changed roofing to metal roofs have also quoted that there was a 20% decrease on their energy bills. All metal roofing material is also made of around 60% to 65% recycled material helping the environment as well.
