GMC Sun Blade vs Flat-Pack Louvre Roof Kits
Not all louvre roofs are designed, installed and supported in the same way. Flat-pack systems may suit homeowners looking for a standard-sized DIY option. The GMC Sun Blade is designed for homeowners who want a custom solution, professional installation and one experienced team responsible for the complete project.

Know Who Is Responsible for the Finished Roof
The product itself is only one part of a successful louvre-roof project. Before choosing a kit system, ask:
Who will assess the proposed fixing points and supporting structure?
Is the installer appropriately licensed and insured?
Who is responsible if an installation issue causes leaking or damage?
Does the warranty cover only replacement parts, or also removal and reinstallation?
How will stormwater be collected and discharged from the posts?
Will the standard size integrate properly with the home?
Who will provide service if the roof requires adjustment later?
With the GMC Sun Blade, you are not simply purchasing a boxed product. You receive practical design advice, a roof tailored to your home, professional installation and ongoing support from the same local company.
One experienced team. One complete solution. Clear responsibility from design through to after-sales support.
