Eaves

If you go back 39 years most houses had proper eaves but now they are less common.

As I travel around I sometimes see new houses with eaves on the front facade but non elsewhere, which I think looks weird.

If you are thinking about ‘eaves’ on your new house here are some advantages and disadvantages.

Advantages

  • The eaves keep the rain off the walls. As well as improving the weather proofing this helps improve the thermal performance of the walls in winter.
  • They will shade north facing windows in summer while letting the winter sun in. (This effect is negligible for windows facing in other directions and only about 50% effective for full length windows and patio doors)
  • Appearance. I think they give a more finished appearance and the shadow line adds interest.

Disadvantages

  • Cost. A typical cost is around $80/m2 so 600mm eaves all the way round a typical house could add around $4,000 to the cost. 450mm eaves will be a little bit cheaper.
  • You can’t build as close to the boundary which can be important if you have a narrow block.

As for me my first Australian house had eaves, but my next house did not so I have a foot in both camps.

I didn’t mind the look of the design without eaves and I built a pergola on the north side for shading.

Are you for, or against, having eaves on your new house?

What’s On The Roof?

A METAL ROOF

This covers zincalume, galvanised steel and colorbond. Following are a few thoughts:

  • In general a metal roof is noisier as you can hear the rain (which I like)
  • They are fairly light so they don’t put as much load on the structure.
  • With modern screw fittings they can be extremely resistant to very high winds and hail.
  • Might get dented but will still be weatherproof in extreme hailstorms.
  • Less likely to leak.
  • Can be laid at lower pitch Which means the roof isn’t as high.
  • They are capable of lasting over a 100 years with minimal rusting.
  • Available in zinc finish or a wide range of colorbond colours. Zinc finish will be best for reflecting heat, followed by lighter colorbond colours.
  • Can be more expensive than tiles.
  • Fitting solar panels will be cheaper and easier on a steel roof.

One drawback is that you will need an external TV aerial and mobile phone coverage may be worse than under a tiled roof.

Tiles

Can be clay, terracotta or concrete. Their characteristics are:

  • Concrete has lower initial cost although some clay tiles and terracotta tiles can be very expensive.
  • Provide better insulation both heat and noise.
  • Heavier.
  • Brittle.
  • Need to be individually screwed down in high wind areas.
  • Wide range of colours.
  • Can add character especially as they age.

I have previously had a steel roof but now have tiles.

If building again I would probably go for metal.
