Depending on the design and façade of your new home there are a few options as far as roof designs go. You can have a typical hip and valley roof which is commonly used with project builders and acreage-built homes. There are more modern styles like a skillion roof, like the one in this video. A skillion roof is often used if you have a high raked section in the centre of the home design and the roof comes together at one point with a boxed gutter.
Another thing to think about in relation to your roofing is if you want solar panels. If you are wanting a solar system on your roof, you will need to ensure you have enough north facing roof to ensure the system operates at maximum efficiency.
Not to be forgotten is the type and colour of roofing to choose for your new home. There is Colorbond and tiled roofing as an option and be mindful when selecting the colour of your roof that darker colours will absorb more heat.
Finally, another roofing feature of the home in this video is a skylight in the shower area. You can see the top part of the skylight on the roof of this house, and it provides a lot of light into the space below for a small installation on the roof. This is another consideration for part of the roof design of a new home.
