Even the toughest metal roof won’t last forever — especially with years of rain, heat, hail, and salty coastal air. If you’re noticing:
- Leaks that keep coming back
- Rust around screws, gutters, or valleys
- Sagging or water pooling
- Constant patch jobs and ongoing repairs
- A roof that’s just… seen better days
It’s probably time for a full metal roofing replacement. And when done right, you’ll not only protect your home — you’ll boost its value, comfort, and efficiency too.
Our Metal Roofing Replacement Process
When you choose Guardian Roofing, you’re getting more than a new roof — you’re getting a full-service team who takes care of it all:
Step 1: Safe Removal & Disposal
We remove your old roof (including asbestos, if needed) and dispose of everything safely and responsibly.
Step 2: Structural Check & Prep
We inspect your battens, insulation, and framing — and repair or upgrade them as required.
Step 3: Installation of New Metal Roofing
We install a brand-new roof using your choice of Colorbond®, UniCote®, or Zincalume® — with precise attention to detail, profile, pitch, and finish.
Step 4: Flashings, Gutters & Fittings
New flashings, cappings, valleys, and gutters for complete waterproofing and a clean look.
Optional: Add insulation, skylights, or ventilation — while we’re already up there.

UniCote® – High Performance, Great Value
