Finding
Zinc roof
What this usually means
Zinc has a long lifespan (60-100 years) when correctly installed and ventilated underneath. Failure modes are corrosion from underside condensation (poor ventilation) and pitting from acid rain in industrial areas.
Why it matters
Premium material, replacement cost is high. Surveyor flag is informational on condition.
Ask your surveyor
- Check:What is the visible condition?
- Check:Is underside ventilation adequate?
Ask the seller
- Check:When was the zinc installed or last refurbished?
- Check:Are there any guarantees?
Next steps
- •Get two written quotes from local trades before negotiating with the seller.
- •Speak to your mortgage broker before exchanging if the finding affects mortgageability.
