This Grade II Listed church near Chorley in Lancashire had a very steep pitch which brought consideration about head fixings and length of each section of lead over the copings.
The church had been suffering from water ingress for some years. We noted that previous attempts had been made to try and resolve the issue.
We accept that churches must fundraise to maintain these historic buildings, which can limit the scope of works.
Our first step was to repoint the copings; which we deemed a key issue as mortar is a weathering course between masonry joints.
Stainless steel strips were fixed either-side of the existing double stacked copings. This strengthens the lapped lead drip detail against wind damage.
A bed of building paper was applied as a protective separation layer from material contents damaging the underside of the lead sheeting. This usage allows expansion and contraction flow in temperature changes.
Reduced lengths of the Code 5 Lead were head fixed to secure to the copings. The lengths were clipped at each lap to provide space for expansion.
Works commenced from the base coping corner drip details to meet at the top where a cross is fixed. The lead was dressed around the base of the cross and lapped into the stone joints to prevent water ingress.
Finally, patination oil was applied to the lead which provides a protective coat. This project started in November with all efforts made to complete prior to our industry shutdown for Christmas break.
