Come across clip locks and are wondering what they are and whether you need them? Clip lock roofing - or ‘klip lok’, as they’re also known - is a way to attach metal material to your roof. This method has recently gained popularity in both commercial and residential buildings; it’s versatile and durable.
What Is a Clip Lock Roof?
A clip lock roof (or klip lok) is a type of metal roofing system that’s typically made from high-quality steel. Sound familiar? Traditionally, we use screws and fasteners. But the thing that makes clip lock roofing different from other roofing options is its concealed fixings - the unique design uses a ‘clip’ to secure the metal sheets to the roof structure, rather than visible screws or fasteners.
Clip lock roofs offer a streamline, crisp and clean finish. But they’re not just about looks. These metal sheets are also made to withstand Australian summer or harsh winter weather conditions. Clip lock roofs are suitable for new builds and re-roofing projects.
What Is Clip Lock Roofing Made Of?
Clip lock roofs are usually made from strong steel or aluminium. But the favourite in Australia is Colorbond steel - highly durable and weather-resistant. Colorbond steel is treated to resist rust and fading, among other damage. Who wouldn’t want to protect their home with such strong material?
And like all roofing sheets, clip locks are available in a variety of colours.
How Do Clip Locks Work?
Concealed clops and interlocking sheets create a strong bond that can withstand wind and rain. This design is flexible to allow for smooth thermal expansion and contraction when the temperature changes - this can help prevent cracking or warping.
What Are the Benefits of Clip Lock Roofing?
Why are clip locks so popular?
Durable
Clip lock roofs are incredibly strong and resistant to the elements - they can withstand high winds and heavy rains, as well as hail.
Weather Resistant
Clip lock roofs are less prone to leaking and water getting into your home thanks to their interlocking design.
Concealed Fastenings
The clean, modern design makes it popular among architects and homeowners who want a contemporary look.
Low Maintenance
Clip lock roofing has a lack of visible and exposed fasteners which requires less maintenance and is less susceptible to rust and corrosion.
Energy and Thermal Efficiency
Clip lock roofs can improve the energy efficiency of your home. Some materials reflect heat and, therefore, reduce your cooling costs.
Long Lasting
Clip lock roofs can last for several decades when properly installed - meaning you’ll get excellent value for money over time.
How to Install Clip Lock Roofing
It’s usually best to leave installation to professional roofers. It’s a complex job that needs proper tools and techniques. But if you’re an experienced DIY-er, here are the steps to install clip lock roofing:
-
Clean and dry your roof. Make sure to free it of any debris. It’s also sensible to inspect the roof decking for any damage that you’ll need to repair before getting started.
-
You’ll need to measure and cut the roof sheets to the right length and width. Precision is important; incorrect measurements can cause big problems.
-
Install the clips at regular intervals along the roof structure. Then, lay the metal sheets on the roof, overlapping for a tight seal.
-
Seal any joints or seams to keep it waterproof.
Finished? Give your work a final inspection to check for any defects or issues.
How to Maintain Clip Lock Roofing
Already got a clip lock roof? One of the best things is that it requires minimal maintenance. But, like all roofs, regular health checks will keep it in good shape for years to come.
Tips to maintain your clip lock roof:
-
Clean your roof dirt like leaves and bird droppings about twice a year to prevent a build-up which can get in your gutters or trap moisture and lead to rust.
-
Check for damage after a storm or heavy rainfall, like dents and scratches or loose panels. Address any issues promptly to prevent worsening.
-
Inspect the flashing around the chimney and vents for signs of wear and tear. Damaged flashing can cause leaks - and these are particularly vulnerable areas.
-
Noticed moss or algae growing on your roof? Use a soft brush and mild detergent to clean it off.

The main difference between clip lock roofing and normal metal roofing way they’re fixed to the roof - and to each other. Clip lock roofing uses a concealed fixing system to secure the roofing sheets in an interlocking design; traditional metal roofing relies on exposed screws or fasteners.
What Is the Minimum Pitch for Clip Lock Roofing?
Clip lock roofing is suitable for roofs with pitches as low as two degrees, although it’s recommended for roofs with a pitch of five degrees - or higher. There are some clip lock roofs available that are specifically designed, manufactured and engineered for low pitched roofs or flat roofs.
What Type of Roofing Is Best for a Flat Roof?
Metal sheets and PVC are best for flat roofs. Although usually recommended for pitched roofs, you can use a clip lock design that’s specifically engineered for a flat roof. These flat roof planes provide a weather-resistant end to your building with smooth interlocking sheets and expansion joints.
