Your choice of roof design can have a huge influence on both the looks and functionality of your new home. In this article, we’re looking at each sloping roof house design from all angles. We’ll talk about the role the pitch and slopes of your roof play in function and looks plus look at the pros and cons of high and low-pitched roofs.

What is meant by a house’s slope?

The slope of your roof is another term to describe your roof’s decline or its angle. The pitch of your roof is arguably the defining element that decides what type of roof design it falls under. A sloped roof is often used as a synonym for a range of roofs.

The slope of your roof can influence a variety of factors

  • how well your home drains rainwater
  • strength against strong winds and wild weather
  • positioning and the effectiveness of your solar panels

How much does a sloping roof house cost?

Sloping roofs can range from some of the most affordable options on the market to some of the most expensive. For example, both skillion roofs and gabled roofs are quite simple designs that have fairly straightforward construction and installation. Along with the design itself, there are a few key factors that will influence the price of your roof including:

  • Size
  • Your build location
  • Materials used
  • the builder you choose

What are the advantages of building a sloped roof house?

Pros of a High-Sloped Roof

Improved drainage

A steeper angle will allow your roof to make the most of gravity when you experience a downpour. Quality gutters and pipes will ensure this runoff doesn’t pool on your property and is dealt with appropriately. If you’re in one of the rare places in Australia that experiences snow, a steeper slope will better manage this as well.

Aesthetically pleasing

Sloped roofs can suit a wide range of home designs from a gabled roof for a classic, traditional design to a butterfly roof or skillion roof for modern houses.

Pros of a lower slope roof

Sleek, clean modern look

For modern houses, a lower-pitched roof can be an ideal look. Examples include low-pitched butterfly roofs, skillion roofs or even flat roofs with a slight slant for drainage purposes.

Offers more resistance to strong winds

Lower sloped roofs, such as hip roof designs offer better resistance to strong winds, making them an ideal choice for cyclone-prone areas.

What are the disadvantages of building a sloped roof house?

Cons of a higher-pitched roof

More prone to cyclone damage

Sloping roof designs like gable roofs can be more vulnerable to strong winds, hail and cyclonic conditions. It’s important to check what the weather conditions tend to be like in the area you’re building in as this will influence decisions from the pitch of your roof to the insulation you decide to use.

Cons of a lower-pitched roof

Can have drainage problems

Lower-sloping roof designs can have more issues with rainwater, especially if they are not well designed. This can lead to water damage, mould and other issues in the long run.

What are the most popular sloping roof house designs?

There is a wide range of roof styles that incorporate a noticeable slope into their design.

Mansard roofs

A mansard roof, also known as a French or curb roof, is a mixture between a hip roof and a gambrel roof. It’s sometimes considered a modernised version of a gable roof, where it has a similar slant, but has four sloping sides rather than two.


  • Aesthetic value
  • Suits rural areas
  • Sturdy Structure


  • Expensive to build
  • Not always to most weatherproof design
  • May be tough to get approval in certain neighbourhoods and estates.

  • Simple design that’s easy to design, construct and install
  • More affordable
  • Good for drainage


  • Can be vulnerable in cyclone-prone areas

A skillion roof is a single-panel roof design that has a noticeable slant or lean to it.

  • Popular design in Australia


  • More expensive than designs like a flat roof, gable roof, mansard roof or butterfly roof designs

Sloping roof vs the competition

Sloping roof buildings is a category that encompasses many different designs. However, here are some other designs you could consider for your new home.

Flat Roof Design

  • Great for modern houses
  • Simple, affordable design.
  • Can help you get more ceiling space inside the home.


  • Can have drainage issues
  • Not suitable for traditional houses.
  • Can absorb heat and rise the temperature inside your home.
