Frequently Asked Questions
A lead box gutter is a concealed drainage channel built into the roof structure, typically behind a parapet or between a roof slope and a wall. They fail because the original lead sheets were undersized, joints were not correctly lapped, or expansion allowances were omitted — causing the lead to crack under thermal movement. Rotten timber decking beneath is a secondary cause.
Box gutters require Code 5 or Code 6 lead depending on the gutter width and depth. Heavier code lead is more resistant to thermal fatigue and gives longer service life. For gutters carrying significant water volumes or in exposed positions, Code 6 is the recommended standard.
The Lead Sheet Association (LSA) publishes technical standards for lead installation covering joint details, fixings, expansion allowances and minimum thicknesses. Work carried out to LSA standards is correctly detailed to prevent the premature failure that results from common installation errors, and many roofing warranties require LSA-compliant installation.
Natural slate is the historically correct material for Victorian roofs and performs excellently when fixed correctly with stainless steel nails to treated battens over a breathable membrane. We source premium slates suited to each project and fix them to current standards, maintaining the period character of the property while ensuring modern weather performance.
