When a roof leak keeps coming back despite previous repairs, you need a specialist who finds the actual source — not just the obvious symptom. Johnson's Roofing provides professional roof leak detection across West Glamorgan using systematic inspection, moisture mapping and decades of local roof experience. We trace the water path back to its entry point and quote for a permanent fix.
We inspect ceilings, loft and roof exterior systematically — eliminating each possible source until the real entry point is identified. Where useful, we use moisture meters and hose-testing. You receive a clear written diagnosis and a fixed-price quote for the permanent repair. No obligation, no upselling, no guesswork.
Yes. We frequently solve leaks that other roofers have given up on. Our systematic approach finds entry points that surface-level inspections miss — particularly wind-driven leaks where water travels metres along timbers before showing inside.
We charge a fixed diagnosis fee upfront — you know the cost before we start. If you proceed with the repair, the diagnosis fee is often deducted from the repair quote.
Most inspections take 1-2 hours. Stubborn leaks may require hose-testing or a return visit during rain — we'll discuss this upfront if the situation calls for it.
We tell you straight. We'd rather refund the diagnosis fee than guess and waste your money on speculative repairs.
