What does a survey of an old roof look like?
We go slowly. We photograph every slope, the ridge, the chimney and the valley, which is the inner angle where two slopes meet and drain. Old roofs are often a patchwork of repairs, with different tiles and mortars from different decades, and a photograph of each patch is more use to you than our opinion of it. We then say which parts we would repair, which we would leave alone, and what we cannot judge until a tile is lifted.
Chimneys on older houses earn the same attention. Flaunching, the mortar cap holding the pot, cracks in frost, and a cracked cap lets water straight down the flue. Checkatrade's October 2026 guide gives around £750 as an average for repointing a chimney, and rebuilding above the roofline runs from £1,000 to £3,500. The written price we send is for your stack only, after we have seen it.
The same approach applies to lead flashings in a listed building, where a repair may need to match what is already there. Our chimney repairs page shows how we deal with stacks, pots and flashings together, and the survey notes record the lead that is sound as well as the lead that is not.
