The real problems usually begin with
- poor detailing,
- incorrect ventilation,
- ageing underlays,
- condensation build-up,
- movement stress,
- or installation mistakes.
Different roofing systems often develop different failure points over time
- shingles — flashing and ventilation issues,
- metal roofing — thermal movement and condensation,
- slate and tile roofs — ageing underlays and ridge failures,
- corrugated systems — failed fixings and lap leaks.
Even premium roofing systems can fail prematurely if the roof build-up, detailing and ventilation are not designed correctly.
Long-term roof performance is rarely about a single product alone — it’s about how the entire roofing assembly works together.
In roofing, details are everything.
Long-term performance belongs to the whole assembly.
