Roof Replacement Costs Explained

Australian Tips on Roof Replacement & Costs

Roof Replacement Costs

Roof Replacement Costs

Many Australians put off replacing their roofs arguing that it is a costly project and that it takes a long time to have a new roof installed. They therefore bury their heads in the sand as they tolerate many years of rain water leaking into their houses and a low self esteem because of how ugly their old roofs look like. They would rather hide the identity of their houses rather than feel embarrassed showing it out to others. You however need not stomach all that. Roof replacement isn’t an expensive project as many people think. With a good roofing contractor, it also doesn’t take so much time to have your old roof inspected, measured, costs agreed on and the roof replaced. Again, you can estimate the amount of money that you will need to spend in order to replace your old roof by multiplying the area in square metres that the roof occupies by the cost charged in square metres. We are proud to be partnered with VIP Roofing Brisbane who look after our roof replacement clients when we have an overload of work.

Do you need a new roof replacement?

Before you even think about the cost of your new roof replacement, you need to ask yourself whether you really need a new roof and why. If parts of the old roof are too chipped off to repair then you definitely need a roof replacement. If water damage has taken a toll on your roof, you will need a replacement. However, if you feel that you can continue living under the old roof for a lengthier period of time with minimal repairs here and there, then go for the option of having it repaired.

Bad weather can call for roof replacement

Roof replacement can also be necessitated by the prevailing weather conditions. Melbourne is a windy area. If you had installed concrete shingles on your old roof, you might think of replacing it with colorbond or metal roofing owing to the fact that shingles might be blown off their place by the strong winds.

Aesthetic beauty of your old roof

Aesthetic beauty might be another good reason to replace your roof. Once your standards of living improve, you might feel that your asphalt roofing does not suit a person of your status. Therefore you shop around for a better roofing material such as wooden shingles that rhyme with your new found lifestyle.

Once you are sure that you indeed need a roof replacement, you can go ahead and estimate the costs that you will incur in the replacement. The question then is—how do you estimate the cost of your roof replacement?

How to Estimate the Cost of your Roof Replacement

Tips For Pricing Roof Replacements

You do not have to hire a roofing contractor to inspect and approximate your roof replacement costs. No, you can do that on your own. All you need to is know that your replacement will largely be determined by:

  1. The size and complexity of your roof
  2. Roof Material of preference
  3. Labor costs you will incur for workmanship.
  1. The size and complexity of your roof

A large roof will of course require more money to replace unlike a smaller roof. A steep slanting roof will also require more money as compared to a flat level roof since the contractor and his workmen will be at a higher risk of falling off from the roof will replacing it. To measure your roof, you can use Google Earth’s ruler function to calculate the sizing of your roof. You can also climb up the roof if it is not dangerously steep and measure the dimensions of the roof. Again, if you had original plans of the old roof containing the dimensions, you can use them. With these dimensions, ask your preferred roofing contractor how much they charge.

  1. Roofing Material of Preference

The cost of your roof replacement will largely depend on the materials that you want to have on the new roof. Colorbond and zincalume roofing are cheaper as compared to terracotta roofing material. Metal roofing is also more expensive as compared to asphalt and lasts for lengthier period of time. On average metal roof replacement is done at prices ranging from $80 to $150 per square metre. Once you state the roof material you prefer, your roofing contractor will be able to give you a quote of how much they charge per square metre for the material. It is important to note that the roofing material you choose will determine your roof lifespan. Therefore, do not be tempted to go the cheap way since you might find yourself replacing your roofs after every couple of years.

  1. Labor Costs

Apart from paying your contractor and buying the roofing material, you will be required to meet labour costs for the roofing workmen. These labour costs will be discussed between you and the contractor and will depend on how much time the workmen may spend removing the old roof, disposing it and installing the new roof. Again, the sloping and height of your roof will play a role in how much you pay. If the steep slants, you might pay more as compared to someone having a flat roof.

Most Melbourne roofing contractors have roof replacement estimation forms on their websites where you fill in your roof dimensions, height, slant and materials of preference so that you can get a rough quote of how much you will be charged. You can also send them an email with your roof details so that they estimate how much you might spend in the replacement exercise.
