Low-pitch roofs leave no room for compromise. A slope of just a few degrees might offer striking architectural appeal, but it demands a roofing profile with serious credentials — watertight performance, structural integrity, and compliance from the get-go.
That’s why builders, architects and designers trust LYSAGHT KLIP-LOK® — a concealed-fix roofing solution precision-engineered from COLORBOND® or ZINCALUME® steel. Whether it’s a residential extension or a large-scale commercial build, KLIP-LOK® combines aesthetic clarity with lasting performance on even the lowest pitches.
Why Low-Pitched Roofs Require Purpose-Built Profiles
Low slope roofing (generally 5° or less) presents challenges such as water runoff and thermal movement. To avoid pooling or water ingress, your roofing profile needs to be:
- Designed for minimal pitch installations
- Equipped with concealed fixings to protect from weather exposure
- Compliant with the National Construction Code (NCC)
- Capable of accommodating thermal expansion
KLIP-LOK® meets each of these demands — with minimum roof pitch as low as 1° when manufactured from 0.48mm Base Metal Thickness (BMT) steel.
Meet the KLIP-LOK® Range
The KLIP-LOK® range includes:
- KLIP-LOK 700 HI-STRENGTH® – A bold, high-strength profile with wide, fluted pans for contemporary buildings
- KLIP-LOK 700 CLASSIC® – A profile with traditional visual appeal and structural reliability
Both are manufactured by LYSAGHT using COLORBOND® steel or ZINCALUME® steel, combining architectural flexibility with robust performance.
What Makes KLIP-LOK® Ideal for Low-Pitch Roofing
✔ Concealed Fixings – Watertight, clean-line finish with no exposed screws
✔ Low Pitch Capability – Install down to 1° with 0.48 BMT steel
✔ Thermal Movement Accommodation – Clip system allows for expansion and contraction
✔ Compliance with Standards – Fully aligned with the NCC and AS/NZS 1562.1:2018
✔ Visual Appeal – Streamlined, modern finish suitable for residential or commercial builds
A Real-World Example: The Contained Project, Aireys Inlet VIC
In Victoria’s Surf Coast region, the Contained Project — a modular home designed for off-grid living — demonstrates how KLIP-LOK® excels in low-pitch applications, even in demanding coastal environments.
Designed by architect Rema O’Neill in collaboration with Green Magazine, this innovative prefabricated structure required roofing that would not only enhance its minimalist aesthetic but also perform reliably on a roof pitched at just a few degrees.
LYSAGHT KLIP-LOK® 700 CLASSIC®, roll-formed from COLORBOND® steel in Monument®, was chosen for its concealed fixing system, thermal expansion capability, and ability to be installed at pitches as low as 1°. The result is a streamlined, durable finish that enhances the building’s clean architectural lines while providing long-term weather protection.
Whether viewed from above or nestled within the native coastal landscape, the LYSAGHT KLIP-LOK® profile helps unify the design language — delivering both form and function.

How KLIP-LOK® Compares to Other Roofing Profiles
While LYSAGHT offers a wide range of roofing solutions — including traditional corrugated and pierced-fix profiles — KLIP-LOK® brings a unique set of advantages that make it especially well-suited for low slope applications.
Compared to corrugated profiles, which typically require steeper roof pitches and use exposed fasteners, KLIP-LOK® offers a more refined approach. Its concealed fixing system delivers a sleek, uninterrupted surface, while its ability to perform at pitches as low as 1° makes it ideal for contemporary architectural designs where low rooflines are a feature.
Rather than using exposed screws like pierced-fix systems, KLIP-LOK® employs a concealed clip mechanism. This design delivers a sleek, uninterrupted finish and enhances watertightness, making it especially well-suited for low-pitch applications where a streamlined appearance and reduced maintenance are key considerations.
Ultimately, KLIP-LOK® is engineered to meet the demands of projects where clean lines, low pitch performance, and lasting durability are non-negotiable — all while complementing the broader portfolio of profiles LYSAGHT provides.
Applications Beyond Roofing
