Roof and ceiling leak detection

Rain ingress has to be reproduced before it can be confirmed. Staged flood testing does that one section at a time.

Call 0333 567 2635

Seven days a week, 7am to 9pm

What usually brings us out

  • A stain that darkens after heavy rain and fades between
  • Blown plaster or a sagging patch of ceiling
  • Standing water on a flat roof long after the rain stops
  • Damp at the head of a window or around a rooflight

How we go about it

  1. 1Moisture readings and a thermal survey inside, first
  2. 2Drone survey of large or steep roofs, with no scaffold to book
  3. 3Staged flood testing outside, one section at a time
  4. 4Tracer gas into the roof build-up where flooding is not practical

Roofs, ceilings and rain ingress in one visit

Roof repairs normally require a second visit or a roofing contractor. The location and the written evidence are completed on the day.

  • Excellent Leak Detection and Repair

    We had a major water leak of approximately 220 litres per hour and, with a holiday booked only a few days later, we urgently needed someone to find and repair it. […] Frank arrived at our house. He was extremely polite, professional and clearly very experienced. He quickly set up the equipment, carried out a tracer gas test and pinpointed the leak to an area just outside our garage underneath the driveway. […] The whole job, from arriving at our house to finding and repairing a 220 litre-per-hour leak, was completed in around three hours.

    Shortened. The marks show where text was left out.

  • Fast, effective leak diagnosis and repair

    Fundamentally, the engineer (Mark Pavitt) identified the source of the leak, repaired it and had our house back up and running within the same day. As part of achieving this, he kept the damage to a minimum (only having to cut out sections of the kitchen plasterboard ceiling). He cleaned up the debris, was polite, cheerful and informative of root cause and actions throughout the day. I think the key to success is having an engineer that has expertise in both leak detection and plumbing.
