Installation of new 510mm wide code 4 lead on the valley boards & newly refurbished cast iron gutters, replacement of broken tiles & re-pointing of failed mortar.
We have replaced the failed lead on the valley boards using shorter lengths of lead. When the original lead was installed it was cut into lengths of 1.5 meters. This is too long for lead this wide as it is technically in a liquid state at the temperatures that we experience in this country (which is why it is so malleable making it a very workable material for roofing) & the lead therefore sags under it’s own weight causing it to slowly split & tear over time. To prevent this happening again we cut the lengths of lead at 0.9 meters
