How Long Does a Roof Last in the UK?
Roof lifespan depends on material, install quality and exposure. Here are the realistic UK numbers and the signs to watch for as you approach end of life.
Key takeaways
- Welsh slate: 100 plus years.
- Concrete tile: 50 to 60 years.
- GRP and EPDM flat roof: 20 to 30 years.
- Felt flat roof: 15 to 20 years.
- Lead flashing: 60 plus years done properly.
Pitched roofs
Welsh slate, 100 plus years. Spanish slate, 60 to 80. Fibre cement slate, 40 to 60. Concrete interlocking tile, 50 to 60. Clay plain tile, 80 plus. Pantile, 80 plus. Lifespans depend on quality of original install, ventilation, and basic maintenance like clearing moss and replacing failed mortar.
Flat roofs
GRP fibreglass, 20 to 30 years. EPDM rubber, 20 to 30. Single ply membrane, 25 to 35. Three layer torch on felt, 15 to 20. Old style pour and roll felt, 5 to 10. Lifespan depends on substrate, drainage, and whether the roof is walked on regularly.

Signs you are at end of life
Multiple slipped tiles each winter (nail sickness). Mortar crumbling across ridge and verges. Felt visible from inside the loft and falling apart. Tiles delaminating or porous. Sagging roof line. Persistent damp on internal walls. If you see two or more of these, get a written quote for a reroof.
