The roof construction

Choosing a roof

The roof is the most dominant feature of a house. From the road, it usually accounts for about a third of the visible area. And from a functional standpoint, it’s above everything – the integrity of the structure below depends on the roof’s performance in wind, rain, heat and cold. Clearly, choosing your roof is a process that demands careful attention.

How to choose your roof for a new roof

The roofing decision you’re about to make will have long-term consequences. Get it right and the life will be easier and safer for you and your family – no worries about leaks, maintenance or extreme weather.

Here’s a checklist of activities that will help you to arrive at the best conclusion.


  • Get to know the roofing materials market

    You should research the pros and cons of every type of roofing material that you’re considering. In New Zealand, the prospects include lightweight steel roofing, concrete tiles, long-run iron, corrugated iron, clay tiles, timber shingles and asphalt shingles.

  • Talk to an architect or house designer

    The angle and shape of your roof could limit your roofing material choices. Ask an architect or designer if there are any options you should exclude.

  • Drive the streets with your camera

    Visit areas of your town or city that have homes similar to the one you’re building. Use a digital camera or phone to capture roofs that you admire. At the same time, you can take snapshots of colour schemes and landscaping elements that you like.

  • Look at online roof galleries

    Browse to see images of homes. Other roofing manufacturers have similar online galleries. Print images that reflect what you’re trying to achieve with your home; don’t forget to note the product name and colour.

  • Consider extreme conditions

    Some roofing materials require special fasteners, coatings, reinforcement or maintenance for extreme conditions, so your roof might cost more and take longer to build if you live by the sea or in a high-wind zone.

  • Read the warranties

    Roofing warranties should be carefully considered. Some are more comprehensive and last longer than others. Some roofing companies won’t give you warranties, if you install a PV-panel on their roof. Clarify it first with your roofing company.

  • Collect a folder of favourite roofs

    Keep your roofing information and favourite roof images in a folder or scrapbook for easy reference. When you feel that the information and image gathering stage is over, spend some time discussing and eliminating roofs with your partner or a friend.
