Roof Leak Detection for Flat Roofs

Roof leak detection finds where water gets into a flat roof without cutting into sound roof. We combine non-invasive electronic leak detection with drone surveys, so the fault is located before we quote for any repair. A typical house roof takes a few hours to test, and you have the answer the same day.

Water seldom shows inside the building directly beneath the point where it enters. It can run along the deck and through the insulation first, so looking for the stain on the ceiling rarely leads to the fault.

Where access is difficult or unsafe, a drone survey lets us view the roof from above with no scaffolding or ladders. Once we know where the fault is, you receive a no-obligation quote, and our flat roof repairs page covers the work that follows.

Flat roof leaks have many causes. These jobs show a few we have dealt with.

• Leydene Road. The old skylight leaked and water stood on several roof areas. A new timber frame took a sky lantern, and a tapered insulation scheme with a drop-down cleared the standing water on the top bedroom roof.
• Pennsylvania Castle, Portland. Three roof areas on a hotel and wedding venue were suffering water ingress and condensation. We planned the works so we were not on site during an event.
• Rothesay Point, Highcliffe. A low-pitch tiled roof was letting water in during high winds because of its degree of fall. We re-covered it in Alwitra single ply, following wind load calculations.
• Gold Street, Stalbridge. An old, failing sedum and flat roof system was causing water ingress into the home, and we replaced the whole system in two weeks.
