What is long run roofing? In simplest terms, it’s a roofing method that uses continuous sheets of pressed metal or steel, often cut to your home’s exact specifications.
Good news—this type of roofing is gaining popularity across New Zealand for its durability, clean lines, and low upkeep. A recent industry survey suggests that about half of new houses nationwide use some form of metal roofing, thanks to its weather resistance and extended lifespan.
If you’re seeking a dependable roof that looks good and performs well, you’ll find this ultimate guide useful. Below, we’ll show you the fundamentals, benefits, installation pointers, and more.
Long run roofing essentials
Long run roofing is typically made from rolled steel or aluminium sheets, formed into profiles that help water and debris run off easily. These sheets are cut to length, then laid on top of your house’s framework.
- Common materials: Galvanised steel, zinc-aluminium alloy, or sometimes aluminium itself.
- Profiles: Trapezoidal (also called “ribbed”) or corrugated, which channel water away.
- Coatings: A layer of paint or protective film to guard against corrosion and enhance colour.
When you hear about “long run roofs,” the emphasis is on the continuous panels that span from the ridge right down to the eaves. That’s why you hardly see seams or joints, which in turn reduces the chance of leaks or rust.
How it withstands New Zealand conditions
New Zealand’s weather ranges from subtropical in the north to alpine in the south, with salt-laden wind near the coasts. Thanks to advanced coatings and rust-resistant alloys, long run roofing holds up well, even in coastal areas.
The smooth, durable surface also sheds rainwater quickly, helping to minimise any accumulation of moisture or organic matter. This contributes to a longer roof life and less worry for you.
Discover the key benefits
Long run roofing can offer peace of mind, solid protection, and a modern aesthetic. Below are some top advantages that homeowners often mention.
1. Durability
With fewer seams and a robust metal core, long run roofing can last for decades. While the actual lifespan varies based on factors like local climate and maintenance, it’s not unusual to get 30 years or more from a well-installed system.
2. Low maintenance
Because the sheets come in large lengths, there are fewer places where water or debris can collect. You might spend less time clearing out leaves or dealing with moss buildup. Every so often, a simple hose-down and a routine check can keep the roof in excellent shape.
3. Weather resistance
Whether it’s heavy rain, strong sun, or coastal salt air, a quality long run roof is built to handle it. Modern coatings help prevent rust, while the metal panels hold strong against high winds when properly fixed.
4. Energy efficiency
Some coatings can reflect heat, which cuts your indoor cooling needs during hot summers. Combined with proper insulation underneath, long run roofing can help you maintain a steadier indoor temperature year-round.
5. Sleek appearance
Flat or ribbed metal panels often create a modern, clean-lined look that appeals to many contemporary homeowners. You can choose among various profiles for a more traditional or bold style, depending on your preference.
Plan your installation
To get the most out of your new roof, wise planning is essential. This is where you’ll decide who to hire, what materials to choose, and how to make sure you’re following local regulations.
Know your local rules
Councils throughout New Zealand have specific building codes for roofing. In some locations, you’ll need consents if you’re installing metal sheets over an older structure. Before going forward, check with your council or consult a professional who knows exactly what permits are required.
Estimate the cost
Prices vary based on materials, roof pitch, and labour. It’s common for a two- to three-bedroom home to cost several thousand dollars for a complete roof replacement. Though the upfront cost can be higher than some alternatives, the long-term savings on roof repair and maintenance often balance things out. Consider the following when budgeting:
- Material choice (galvanised steel vs. zinc-aluminium).
- Complexity (steeper angles may require additional labour).
- Required consents or inspections.
- Additional features such as skylights or solar panel brackets.
Choose reputable contractors
In New Zealand, long run roofing is a specialised area that requires proper skills. Look for installers who have good reviews and can provide details on their experience.
One example is Kings Roofing, a company known for completing projects on time while maintaining a high standard of craftsmanship. Whoever you choose, request a detailed quote that spells out the timeline, the materials included, and any warranties offered.
Prepare your home
Before installation starts, secure loose outdoor items like garden furniture or potted plants, and inform neighbours of potential noise. It’s also a good idea to have a plan if you need to access your driveway or parking space while materials are being delivered.
Maintain your long run roof
Although these roofs require less upkeep than some other types, regular maintenance can help extend their lifespan.
- Inspect annually: Look for rust, loose screws, or damaged sections, especially after strong winds or storms.
- Remove debris: Clear away leaves, branches, or moss that may accumulate around gutters. This helps ensure rainwater runs off quickly.
- Wash periodically: A gentle wash with water, or a mild cleaning solution if needed, keeps the surface looking fresh. Avoid harsh chemicals that could damage the protective coating.
- Check flashings and joints: Even though long run roofing has fewer seams, the areas around chimneys, skylights, or vents deserve special attention. Ensure these are sealed properly to avoid leaks.
If you spot signs of corrosion or damage, contact a qualified roofer for an assessment. A quick fix now can prevent larger problems down the line.

If you’re ready to enhance your home’s protection and appearance, consider planning your installation with a reliable installer like Kings Roofing, or any reputable professional in your area.
Start by confirming your budget, selecting the right material profile, and ensuring compliance with local regulations. Then, keep up with quick yearly inspections. Good news—most homeowners find that once it’s set up, there’s little more to do than enjoy the peace of mind that a high-quality roof brings.
Common roofing questions
1. How long does long run roofing last?
When installed well and maintained regularly, long run roofing can last 30 years or more. Factors like local climate and exposure to salty air can influence its life expectancy, but most quality systems handle New Zealand’s weather patterns without much trouble.
2. Can I install long run roofing myself?
While some DIY enthusiasts might handle small repairs or sections, a full installation requires specialist knowledge. Even minor errors in fixing or sealing can lead to leaks or damage. Most homeowners find it’s best to hire a licensed roofer for a hassle-free experience.
3. Is long run roofing noisy?
In heavy rain or hail, a metal roof can produce more sound than other materials. However, modern insulation and underlay can greatly reduce noise. Plus, your roofing installer can recommend extra steps, such as insulating panels, for a quieter result.
4. Does colour affect performance?
Yes. Lighter shades reflect more sunlight and can keep your home cooler in summer, potentially lowering energy costs. Dark colours absorb more heat, which some homeowners find helpful in cooler climates. Whichever you choose, ensure it has a protective layer designed to handle New Zealand’s UV exposure.
By taking these points into account, you’re well on your way to deciding if long run roofing suits your style, budget, and lifestyle.
