Questions & Answers
We use Code 4 and Code 5 lead sheet as standard, meeting all British Standards.
Properly installed lead flashing can last 80-100 years.
Minor issues can be repaired, but severely deteriorated flashing should be replaced for long-term protection.
Lead flashing can fail due to thermal expansion and contraction over many years, incorrect original installation, storm damage, or deterioration of the mortar fixing it in place. Regular inspections help catch issues early before they cause leaks.
In many cases, lead flashing can be dressed back into position or patched if the damage is localised. However, if the lead is extensively cracked, split, or corroded, a full replacement of the affected section is the most reliable long-term solution.
