This was a straight forward part of a larger job. There were two defective sections of lead on the roof that were soon going to crack and allow water through. We cut out the defective areas and lead burned new lead patches on.
The defective areas before work commenced.
Defective lead cut out and area swept clean.
You cannot lead burn at all until all oxidization has been scraped off the lead (both the new lead and the old).
These last three pictures show the completed work. The area is now safe from leaks.

These first two shots show natural hydraulic lime mortar being applied on top of a slurry mix designed to increase and retain adhesion.
These 2 shots show the completed skew – still moist and beginning the curing process.
Skew now hessian covered. The curing process takes a long time. Lime reaches full strength over an extended period of time, but the first three days are the most critical and it’s during this period that we make sure the work stays protected. The point of the hessian is twofold – it’s there to: protect the mortar from the weather, and (importantly) prevent it losing moisture too quickly.
