How to Know When Your Roof Needs Replacing

Signs Your Roof Needs Replacing

1. Persistent Leaks & Water Damage
   If you’re noticing damp ceilings, water stains, or mould growth, your roof could have hidden leaks. Even minor leaks can escalate quickly, damaging insulation and interior walls.
2. Rust, Corrosion, or Broken Tiles
   Metal roofing, especially older galvanised steel, can corrode over time. Rust spots or cracked tiles expose your home to the elements, making your roof vulnerable to further deterioration.
3. Sagging or Warping Roof Structure
   A sagging roofline can be a sign of structural weakness. This is often caused by moisture damage, rotting timber, or poor installation.
4. Frequent Repairs & Ongoing Issues
   If you’ve patched multiple leaks, replaced broken tiles, or resealed flashings more than once in the past few years, a full reroof may be more cost-effective.

Should You Repair, Restore, or Replace?

• Minor damage? A roof repair may be all that’s needed.
• Surface wear & fading? A roof restoration (cleaning, sealing, and repainting) can extend its life.
• Significant damage or an aging roof? A full roof replacement ensures long-term durability and protection.
