Custom Roof

Roof Replacement Process

1. Our friendly Custom Roof representative will arrange a suitable time and day to visit your home to visually inspect, measure your roof and discuss your exact needs and wants from a new roof. An itemised, ‘all-inclusive’ quote is then supplied to the homeowner.

2. Once the customer feels fully informed and satisfied, they can accept the quotation. No immediate deposit payment is required now (50% deposit only payable on delivery/installation of materials on site).

3. An estimated start date is provided to the customer. Unfortunately, due to the weather, delays are part of roofing and should be expected. 

Putting a new roof on a property can take anywhere from a day to a week, depending on the size of the roof, the complexity of the job, and how well the weather cooperates.
As a guide, our experienced team of roofing installers will go through these seven steps:

1. Safety first. Set up safety edge protection/scaffolding. Before commencing any work – we install edge protection/scaffolding around the perimeter of the roof to ensure we can work safely at heights. This can be installed up to a week prior to roofing works commencing.

2. Materials delivered. All roofing materials are delivered a day or so before work begins. These are placed in a safe, yet convenient location to allow our team to work efficiently on roofing day.

3. Remove the old roof and inspect the roof structure for defects. Our team will begin stripping your existing roofing away; assessing the underlying structure as they go. Should any rotten or damaged timbers be uncovered, these will be replaced as required.

4. Prepare roof surface (underlay, insulation when required). We install a self-supporting synthetic roofing underlay to minimise condensation and improve the acoustic and thermal performance of the roof. New ceiling insulation is also installed at this time (if requested). This is easy to install when the roof is being replaced! We install roof insulation and underlay according to specifications and our quotation.

5. Install your new Colorsteel® roof (including ridging, associated flashings etc.) The Custom Roof team will now begin installing your new roof. This part of the process is usually completed quickly and efficiently. Your roof will be left clean and tidy, with any excess materials carefully removed.

6. Finish, site clean-up and final inspection. A magnetic sweeper is used to pick up stray roofing nails and smaller metal debris around the house. We organise the removal of all old roofing materials and product packaging. removed and taken away from the site.

7. Dismantle safety edge protection/scaffolding.

Unfortunately, roofing installers can not safely complete re-roofs in bad weather! Rain, high winds, frost and moisture can potentially delay the installation of your new roof by a day or two.

Because your house can be exposed to the elements during re-roofing (only for a very short period of time), our qualified roofers will ensure they proceed only when it is safe to do so, and that the team has a safe environment to work in. They will work around the weather where possible, to ensure your roof is installed in a timely manner – but please be aware that weather causes delays. If this happens, we’ll keep you informed!

While we do our best to limit the inconvenience, getting a re-roof is a reasonably large renovation. Here are some things to be prepared for and some actions you can take to help make the process go as smoothly as possible for yourself, and the workers.

  • Re-roofing is noisy. It is best to make prior arrangements if you have a home business or small children that may be affected by this.
  • As much as possible, try to leave the driveway and yard clear. Scaffolders, workers and delivery trucks will need to get as close to the house as possible.
  • We may need to block access to garages during the process. If possible, try to arrange street or another form of parking during the day. This way we will not hinder you from going about your business.
  • We take as much care as possible to protect your house, plants, and other items. However, if possible, remove any valuables from the exterior of your house (BBQ, potted plants etc, and put them in a safe place.
  • Make sure there is a working power source on site, preferably on the exterior of the house. If you need to leave for the day and don’t have exterior power, please let us know and we will arrange to run an extension cord from inside the house.
  • It’s best to let your neighbours know if you are having your house re-roofed. That way they are prepared for the likelihood of some inconvenience, especially if you have a shared driveway that we will need to use.
  • Some debris will fall on the ground. We do our best to limit this, but it will happen. Please take care when entering and leaving your property. Our workers comply with strict safety regulations and want to keep you safe.
  • Once the job is complete, the workers will do a thorough cleanup. However, once the scaffold is down it may reveal some debris that we were not able to access. Simply give us a call and we will send someone to do a second clean.


If you have any concerns, please do not hesitate to talk to one of the workers if you have any immediate queries.

No, there is usually no need to move out. But you do need to consider the comfort and safety of the household.

  • Our work can be quite noisy during the day. If you enjoy peace and quiet during the daytime, then it might be a good idea to consider an alternative location during the hours we are on the roof.
  • Like any work site, ours has hazards like vehicles, tools, people and scaffolds. We manage our safety carefully, but unexpected visitors can expose themselves to risk. Children need to be closely supervised and kept well clear of where we work to avoid accidents.
  • Like us, cats and dogs can find the noise and activity disconcerting. Cats generally avoid us, however, curious animals can be a hazard to themselves. You may want to consider keeping them inside, or an alternative arrangement during working hours- for the comfort and safety of your pets.
  • If asbestos roofing is being handled, we will discuss specific safety requirements with you directly. Although there is no requirement to move out, you might consider it convenient.
