Slate roofing has long been regarded as one of the most durable and visually striking roofing systems available. Found on some of Sydney’s most prestigious heritage homes and buildings, slate roofs can last well over 100 years when installed and maintained correctly.
However, one of the most common causes of failure in older slate roofs is something known as nail sickness.
Why It’s Common in Sydney?
In coastal areas like the Northern Beaches, Eastern Suburbs, and Inner West, salt air and moisture accelerate corrosion. That’s why many Sydney slate roofs experience nail sickness after 50–100 years.
Signs Your Slate Roof Needs Repair
- Slates slipping or falling
- Recurring leaks
- Frequent patch repairs
- Visible rust or loose tiles
If you notice these, it’s time for a professional slate roof inspection.
The Solution: Re-Slating vs Re-Nailing
When nail sickness is present, patch repairs are often only a temporary fix. The long-term solution typically involves a full roof overhaul, which may include:
Re-Slating (Salvage & Reuse)
Where the existing slate is still in good condition, it can be carefully removed and reused. New, high-quality fixings such as copper nails are installed, ensuring longevity for decades to come.
Full Replacement
If the slate itself is brittle or damaged, a complete re-roof using new slate may be required.
