Lead Flashings & Valleys
Lead does the unglamorous work that decides whether a pitched roof lasts 30 years or 80 — chimneys, valleys, parapet abutments, bay-window aprons.
Lifespan
60–100 years from properly fixed code-rated lead.
Cost / m²
Code 4 from £55/m², Code 5 from £75/m² — usually quoted by linear meter on flashings.
Category
metal
Best for
Chimney stacks, valleys between roof slopes, abutments to brickwork, bay-window apron flashings.
Where it fails
- Splits at bay-roof aprons from thermal movement on long pieces
- Mortar pointing failing above stepped flashings
- Cheap flashband used in place of proper lead
- Lead theft on accessible single-storey roofs
Our repair approach
We use Code 4 minimum, lap pieces to allow movement, and chase flashings into a proper mortar joint rather than relying on mastic alone.
