Why Your Roof Warranty Depends on Proper Installation & Compliance

Your Roof Warranty Is Only as Good as the Installation

Buying high-quality roofing materials is smart — but it’s not enough.
Because even the best Colorsteel or ColorCote roof can lose its warranty the second it’s installed incorrectly.

At Aquashield Roofing, we see it too often: beautiful materials, installed poorly, and now the warranty’s void.

Let’s make sure that never happens to you.

1️⃣ What a Roofing Warranty Really Covers

There are two parts to every roofing warranty:

✅ Material Warranty – Covers the product (steel, coating, colour) from the manufacturer.
✅ Workmanship Warranty – Covers the installation quality from your roofer.

If the roof leaks, rusts, or fails because of poor workmanship — the material warranty doesn’t apply.

Manufacturers like Colorsteel, ColorCote are clear:

“Your warranty is only valid if the roof is installed according to manufacturer guidelines and the NZ Building Code.”

2️⃣ How Roofers Void Warranties (Without Knowing It)

Common mistakes that void warranties:

• Incorrect fasteners or patterns
• Missing or poorly installed underlay
• Wrong roof pitch for profile type
• Improper flashing overlaps
• Cutting sheets with angle grinders (burns coating)
• Failing to register the warranty with the manufacturer

These are all compliance issues, not material defects.

At Aquashield Roofing, our installation standards follow E2/AS1 and manufacturer specs — so your warranty stays 100% valid.

3️⃣ Why Documentation Matters

Manufacturers and insurers require proof of:

• Installer credentials (LBP, RANZ, or approved applicator)
• Compliance photos and job records
• Material batch numbers and warranty registration

That’s why we document every job from start to finish — including materials, fixings, and photos.

When we hand over your final documents, you’re not just getting a roof — you’re getting proof of compliance and protection.

✅ Final Word: Protect Your Roof, Protect Your Warranty

Your roof’s warranty isn’t automatic — it’s earned through proper installation, documentation, and compliance.

At Aquashield Roofing, we build every roof to meet the standards that keep your warranty strong for decades.
