Building new: consider the roof

CHOOSE YOUR ROOF

A new roofing system is a big investment and you may want to add value to your property. Especially re-roofing, you will be amazed how simple and cost effective it is creating additional value to your property. Get it right and make the life easier for you and your family.

MATERIAL

Roofing products are defined as lightweight or heavyweight depending upon their classification within the New Zealand standard NZS3604. A light roof is a roof with roofing material not exceeding 20 kg/m² of roof area i.e. Long-run metal sheets, pressed metal tiles. A heavy roof is a roof with roofing material exceeding 20 kg/m² of roof area but not exceeding 60kg/m² i.e. concrete tiles, clay tiles.

In New Zealand, the type of roofing material includes pressed metal tiles, concrete tiles, long-run corrugated sheets, clay tiles, timber shingles and asphalt shingles. We always suggest you should research the pros and cons of every type of roofing material that you’re considering as your start point. Please see the facts of the metal tile roof.

DESIGN AND STYLES

Choosing your design and style of your new roof is part of the design process when you building your new home. The angle and shape of your roof could limit your roofing material choices. Make sure the roof you’ve chosen will perform at the pitch of your roof. Because the slope / pitch of the roof and strength of the framing could limit your choices. Ask your architect or designer if there are any options you should exclude.

If you are replacing the existing old concrete roof or metal roof, get hold on an experienced and LBP (licensed building practitioner) roofer for free consultation of what type of roof material can be replaced. You can find the Metrotile’s Certified Roofers from our Distributors page.

For inspiration, search online for roof galleries, reading house and architectural magazines, or simply browsing our product gallery to see nice photos of homes with Metrotile roofs.

DURABILITY

How long will it last? The actual life span of each roofing system is determined by a number of factors, including material quality, product design and technology, local climatic and environmental conditions, installation and adequate roof maintenance.

Metrotile’s modern manufacturing techniques enhance this durability giving customers a roofing product that’s sure to last a lifetime. Advances in durability is from the improvements in paint technology most notably the move from galvanized (zinc-coated) to Zincalume® (a combination of zinc and aluminium), which made by New Zealand Steel. The new technology provides robust roofing that will cope with the harshest environments, and gives the steel roof a greater lifespan than before.

PERFORMANCE

Some roofing materials may be not suitable for Very High Wind Zones (VHWZ) in coastal regions; some roofing materials may be not as good as resistance to fire. In this case, if some areas prone to wildfires or hurricanes, better to look for a product with a high fire rating or good wind resistance. Different type of roofing material has its unique property especially the installation method. It is always a good idea to look at the performance of each type of roof and consider if that matches the requirements of your new design or suitable for your replacement roof.

A Metrotile roof is engineered for of New Zealand and is proven around the world to withstand extreme wind conditions in excess of 190kph. The steel roof tiles are classified as a “Class A” fire rated. Please see the Metrotile performance guarantees for more details.

SUSTAINABILITY

You many wonder what roof material made for your roof. Is it eco-friendly made from recycled materials and can be recycled when replaced? Does it create higher carbon footprint than other roofing materials? The main material of the Metrotile’s product is steel, which is 100% recyclable with no loss of quality. You’ll discover more about the sustainability of our products and business.

WARRANTY

Roofing product manufacturers offer a variety of warranties on their products. Take a close look at those warranties to see what responsibilities and financial obligations manufacturers will assume if their products fail to reach their expected lives.As part of the important step, roofing warranties should be carefully considered. Most new roof systems are designed to provide warranty for about 20 years. Some are more comprehensive and last longer than others. Read about Metrotile’s 50 year warranty.

COST

How much will it cost? Does it include the purlins or battens? Does it include additional costs, such as removal and disposal of the old roof? Does it include scaffolding when doing a re-roofing? There are many variables that affect the roof price, for example a simple gable roof cost less than a complicated hip roof; a metal roof is much lighter than traditional concrete or clay tiles and therefore they do not need the structural support that these traditional roofs require, therefore, the Metrotile roof can help to reduce the overall building costs.

There is only one grade – top grade in our product range and is New Zealand made. The Metrotile products are designed and engineered to cope with the extreme weather conditions, there is no extra cost when your house is near the coastal area. Not like other roofing systems need to upgrade to other grade when the house is near the sea.For a free quote of your new roof, please simply send your house plan to info@metrotile.com or fill out the form from the free quote page.
