During the late 90’s Australian’s began acquiring a taste for large homes, and by 2011, the average home size in Australia reached a massive 243 sq metres, surpassing home sizes in the US.

Since then, things have changed.

The latest published figures by Commsec report that homes sizes in Australia have been shrinking year on year in line with global trends to a 22 year low of 186 sq metres.

Our thirst for big homes translates into substantial costs for labour and materials in the construction, repair and replacement of residential roofing.

 

Considerations that vary roofing costs

 

As your home ages, maintenance, restoration and repair become more frequent.

A question many homeowners ask is how much does roof replacement cost; we’re going to do our best to answer this question.

Well, the truth is, there are a variety of factors which vary the cost of roof replacement, such as;

1. Size of the roof
2. Pitch of the roof
3. Roof material and availability
4. Contractor labour costs
5. Does roof require upgrades or repairs?

 

Pitch vs Size.

 

So, when calculating the cost of a roof, we need to know, not only the size of the roof but it’s pitch because pitch alters the area of the roof.

Why, because unless your roof is a flat roof, the roof size varies with the roof pitch, meaning that your roof area is significantly larger than your homes square meterage.

Roof Pitch

Roof sizes vary depending on the pitch of the roof.

 

How roofing materials vary pricing.

 

Replacing your home’s roof provides an excellent opportunity to consider alternatives, like changing the material or colour of your roof.

Of course, changing your roofing material may lead to additional costs.

For instance, upgrading from a metal roof to a terracotta roof often requires further strengthening of your roof bracing, and terracotta tiles are more expensive than metal sheeting.

The four most commonly used materials for roofing are;

1. Metal roofs (Colorbond®)
2. Terracotta tiles
3. Concrete tiles
4. Slate tiles

When considering material types, also think about the location of your home, is it situated near a bushfire threat, is it subject to harsh climate conditions such as severe heat, cold or stormy weather.

The best way to avoid potential pitfalls is to discuss your roofing options with a roofing specialist.

 

Enhancements you might want to consider.

3. Roof Insulation
