Is-My-Roof-Too-Old-for-Coating

Many Kiwi homeowners worry their roof is beyond saving. But in many cases, it's not age , it's condition that matters.

✅ When Coating Still Works:

  • The roof structure is sound (no sagging or rot)
  • Surface rust or minor damage is repairable
  • Tiles or iron sheets are secure

Guardian Seal is designed to revive ageing roofs, even those that look beyond help.

🔁 When Replacement Might Be Necessary:

  • Large rust holes or severely broken tiles
  • Structural damage or active leaks into framing

🛠️ What We Look For in a Professional Roof Assessment:

When you book a free roof inspection, our trained team checks for:

  • Surface condition: rust, moss, cracking, or flaking coatings
  • Structural integrity: signs of sagging, timber rot, or failed support
  • Seal points: flashings, joins, penetrations (vents, skylights)
  • Weathering: UV damage, faded paint, or porous tiles
  • Drainage issues: ponding or blocked gutters that may affect coating performance

We document problem areas, take reference photos, and give you a clear, obligation-free recommendation on whether coating is appropriate, or if more substantial repairs are needed.

Often, coating is still a very real and cost-effective option , even for roofs that appear "too far gone."
