DIY Flat Roof Repairs

We always recommend hiring qualified Cardiff roofers for flat roof repairs - especially for larger leaks, structural issues, or anything above ground-floor level. If you have experience, the right tools and PPE, and the task is minor, some small fixes may be attempted yourself.

Safety first: Working at height is dangerous. Use suitable ladders or scaffold, avoid wet/windy weather, wear non-slip footwear, and never work alone. If in doubt, hire a professional.
