Guide to Your New Roof

Your home can be completely transformed by upgrading the roof. A new roof will refresh the appearance of your home, protect your investment and can significantly increase the value.

We’ll help you choose your new roof and make the process easy.

What to expect when you purchase your new roof with us.

We’ve put together a simple guide that outlines how we’ll work with you to select the best roofing materials for your new home or commercial building.

1. Initial Consultation

Our experienced staff will guide you and help you make a great choice that you’ll be happy with for years to come. We’ll answer any questions you have, explain the different materials and profiles that are available and recommend a new roof that will suit your home perfectly.

2. Select a Product

There is a large selection of roofing materials and roofing styles available. We’ll explain the differences and remove any confusion from the decision making process.

  • Select a Material

The first step to take is to select the material. This refers to the grades within the COLORSTEEL® range . If you want something a bit different like clear polycarbonate or an exotic material like Copper or Stainless steel, we can help you with the details around these materials too.

  • Select a Style

Many homeowners don’t realise there’s a whole selection of styles and profiles available. Depending on the location of your property, we can guide you with the selection of the best profile. Learn more about the selection on our Roofing Profiles page.

  • Pick a colour

There’s a great selection of colours available from the COLORSTEEL® range. If you’re not sure we can help you choose a colour that compliments your home and works well in your neighbourhood. View the full colour range here.

  • Select Flashings and Spoutings

Your new roof will need custom made flashings that are specific to your home. Many people choose to replace spouting and rainwater systems on their home at the same time, and we can help with this too. Learn more about Rainwater systems.

3. Measure

Once you have an idea of the material and style you’re looking for, we’ll come to your home and get the measurements we need to give you an accurate quote. You don’t even need to be there for this if you don’t want to be, as long as there is access to the property.

4. Quotation

We provide you with a detailed quotation. Our quotations are clear and explain everything needed to remove your old roof, install your new roof and leave the site looking tidy afterwards. Our quotations also outline the warranty you’ll receive, based on your location and the product you’ve selected. Note that you can increase your warranty period by selecting a higher spec product – talk to our team about these options.

5. Quotation Acceptance

When you’re ready to go ahead, you can let us know by accepting our quotation. At this point we’ll schedule the job and let you know an estimated day for delivery.

6. Ordering the Materials

Depending on the colour and profile you have selected for your new roof, we may need to order the materials in. Your roofing sheets and flashings are custom fabricated so they fit perfectly to your home in the colour of your choice. Depending on the roof you’ve chosen, this can take some time. We’ll keep you informed, so you know when to expect the installation to take place.

7. Final Scheduling of the Job

There are a number of factors that affect our ability to perform the final job. Some of these factors like the weather (rain and wind) are outside of our control. We’ll keep you informed throughout the process and with our many years of experience, we get our estimates for the job to be completed as accurate as we can.

8. The Installation Process

We’ve outlined some of the key stages of the installation process below, so you have a clear idea of what to expect on your property.

  • Scaffolding arrives on your site. (Sometimes a few days before the job takes place)
  • Your old roof is removed
  • Timber work is done if needed (Repairs to your roof framing)
  • Your new roof is installed
  • The flashings installed – Custom made for your roof to make everything weather tight.
  • Guttering installed if required. Many choose to upgrade guttering at the same time.
  • Quality Check – A company representative will check over the installation to ensure it meets our high quality standards. We’ll meet you to ensure you’re happy with the final product.
  • You sign off that you’re happy with the job
  • The scaffolding comes down. (Many people choose to do other maintenance to their home while the scaffolding is up. Things like painting, cleaning and replacing worn cladding can all be done while the scaffolding is on site. Talk to us about this if you want the scaffolding there a bit longer.)
  • The site is cleared. We remove all your old roofing materials (unless you want to keep it), tidy up all our rubbish, and leave your property looking tidy.
9. Your New Roof Warranty is Activated

Your new roof comes with a comprehensive warranty that is based on your location and the materials chosen. If you’ve chosen an NZ Steel product like COLORSTEEL® or GALVSTEEL® your warranty is logged in the NZSteel Database.

10. Job Completed!

Congratulations, you now have a new roof! Your new roof is an investment that will protect your home or business for many years to come and add value to your property straight away.

Other Considerations

Environmental factors

Some materials are more suited to certain areas of New Zealand, for example COLORSTEEL® Maxx provides the highest level of protection and longevity in coastal areas within 100m of breaking surf.

Legislation and Building code

There are various other considerations such as local council legislation and building code requirements as well as covenants in new developments that you will need to be aware of. Rest assured, we’ll take care of these details and explain everything to you, so you don’t have to worry about it. We’re working with these details every day so we can help you navigate these considerations.
