Roof repair covers the jobs that keep a roof watertight between full replacements: fixing slipped or cracked tiles, patching flat roof felt or GRP, sorting out flashing around chimneys and dormers, clearing blocked valleys, and dealing with the damp patch that's just appeared on a bedroom ceiling. In Derby, the mix of Victorian terraces, 1930s semis and newer estate housing means contractors here deal with everything from lead flashing on older slate roofs to felt and single-ply repairs on flat-roofed extensions.
When you're choosing someone to do the work, look past the quote and check the basics: are they insured, will they give a written description of the fault and the fix (not just a price), and do they offer any guarantee on materials and labour. A contractor who's happy to send photos of the damage before and after, and who explains why a repair is enough (rather than pushing straight to a full re-roof), is usually one worth trusting. Avoid anyone who wants full payment up front or won't put the job in writing.
