This was a job for the Land Rover, as the scaffolding tower was needed for access, so the trailer had to be towed. The Landie is getting used to carrying lots of my tools, but this time space had to be reserved for younger son's dog, who is staying with us at present. Stock items included nails, screws, battens and two rolls of heavy roofing felt, left over from the days before we gave up on felt on our own stable and took the profile steel route.
The best part of four panels (each 8 feet by 4 feet - still manufactured imperial in all dimensions except thickness - 18mm!) had to be knocked out to get rid of the rot. The most difficult part was working on my knees on the ladder and not falling through the roof. That would definitely have slowed things down.
