ColorCote®

For the harshest conditions

Because aluminium doesn’t rust, AlumiGard is suitable for use in ‘very severe’ marine environments, right up to the waterline, as well as chemical or acidic exposure in harsh industrial or geothermal areas. Under AlumiGard’s durable baked-on paint system is the same marine grade aluminium alloy boats are made from.

For added corrosive protection

If your property is close to the coast but doesn’t get hit with the harsh, salt-laden conditions that require AlumiGard, MagnaFlow is the ideal choice. The magnesium in the aluminium/zinc/magnesium alloy coating ‘magically’ helps zinc flow over cut edges, sealing them and providing long term protection against corrosion.

Durability and Value

Suitable for moderate climatic conditions, ZinaCore has a hot-dipped aluminium/zinc alloy coating over a steel substrate. It has a waterborne acrylic or polyester top coat, that uses the latest infrared reflective pigments, baked on a polyester primer, giving an extremely durable paint system at a very affordable price.

Design, pitch and aspect

In addition to the environment, the design, pitch and aspect of the house can also dictate which ColorCote product should be used.

For example, a house with a minimum pitch roof with parapets two kilometres from the surf may still require AlumiGard.

The same house with a steeper pitched roof (which allows rainwater to wash off the worst of the salt residue) may be able to use ZinaCore for the roof but may need AlumiGard for the cladding.

In severe marine environments care needs to be taken with cut edges and penetrations – including screw holes – to prevent the spread of corrosion.

Good design can avoid issues

Overhangs create unwashed areas

The design of your house will affect the life of your pre-painted roofing and cladding. Avoid overhangs and designs that create unwashed areas. These are not naturally washed down by rainwater allowing dirt, salts and other corrosive elements to build up.

You also need to think of how the roof is going to be maintained. All roofs need to be washed down on a regular basis so you need to think of how you are going to access the roof. If the pitch of the roof is too steep to walk on safely you might have to hire a cherry picker or crane every time maintenance is required.

Orientation

Orientation of the roof is important too, particularly in severe environments. It is important when looking at the aspect of the roof that the metal profile is protected from the effects of salt-laden air being driven in from the sea under the roof profile and accelerating corrosion. In severe and very severe environments it is also important that the right roof profile is chosen.

Spouting, valleys and low pitched roofs

The spouting profile needs to be correctly fixed to prevent corrosive wind-driven water and salts being driven up under the sheets of roofing and causing possible early product failure.

Spouting, valleys and low pitched roofs also need to have the correct fall to prevent ponding which can accelerate potential corrosion.

If anything in this section pre-empts a potential issue talk to your architect, builder or roofer, or contact us.

Maintenance helps longevity

All roofing and cladding products require regular maintenance to keep them looking good, to prolong their life and to meet the terms of any product warranty.

The best way to reduce the amount of maintenance required is to pick the right product for the environment. The extremes of temperature, harsh UV rays and salt-laden sea air all eventually take their toll on all New Zealand buildings.

The harsher the environment the more important it is that a regular maintenance schedule is followed – particularly regular washing down of roofs and cladding – to maximise service life and appearance.

Minimum maintenance requirements

• Washing of naturally unwashed areas at least every 6 months.
• Removal of debris from gutters every 6 months.
• Any noticeable buildup of salt deposits and/or other contaminants are removed when identified.
• When considering overpainting please consult with your local distributor to ensure correct procedures are undertaken.
• Inspection of the roof, including fasteners, repair any damage every 6 months.

The distributors listed on our website are approved ColorCote roofing installation contractors and installers. Select your region and find a distributor near you.

We make sure the right product is used for its environment

Most roofing companies offer a ‘warranty’ for their products. All warranties are not the same. Just because a company is willing to give you a warranty won’t make your roof or cladding any more durable or resistant to the elements.

If you don’t meet the demanding conditions, and the roof starts to quickly fail, the full replacement cost may be at your expense.

Maintenance

Basic maintenance will prolong your roof life.

All roofing and cladding products require regular maintenance to keep them looking good, to prolong their life and to meet the terms of any product warranty.

Choosing the right product for the environment is the best way to reduce maintenance time. Talk to your representative or roofing installer for the best advice on your roofs maintenance.

Unique warranties for product and environment

All ColorCote roofing and cladding products come with a written warranty backed by Fletcher Building, one of NZ’s largest companies. Our warranties are specific to a particular building, where it is sited, and the type of roofing and cladding product used.

We’ll let you know which is the best substrate and paint system for the design you are planning and the environment you are building in.
