Membrane system

Leak repairs

Targeted fault-finding and repairs on existing membrane roofs. Moisture mapping and condition reports where needed.

What it is

We diagnose and repair leaks on existing membrane roofs. Most failures aren't sudden; they start at a seam, a termination, or a penetration and grow. We find the source, fix it, and document what to watch.

When to use it

  • Active leaks, especially after the first heavy rain of the season.
  • Visible damage — blisters, ponding, lifted seams, failed terminations.
  • End-of-warranty inspections or pre-purchase due diligence on commercial property.

Leak repair FAQ

Roof leak repair in Auckland — common questions

  • Can you fix my roof leak or do I need a whole new roof?
    MRS will tell you straight after inspection. A targeted repair is often enough — MRS only recommends a re-roof when the membrane is genuinely at end of life. Because most flat roofs don't leak where the water shows inside, the first job is finding the actual source before deciding.
  • How fast can you come out for a roof leak in Auckland?
    Active leaks are prioritised. Get in touch with the address and a photo of where it's showing, and MRS will arrange a site visit as quickly as possible. First response is usually same-day during business hours.
  • Do you repair roofs you didn't install?
    Yes — most leak call-outs are on other people's work. MRS diagnoses and repairs leaks on existing membrane roofs regardless of who installed them, matching the repair to the existing system where possible.
  • Why do roof leaks come back after they've been 'repaired'?
    Most repeat leaks were chased, not diagnosed. Water travels along the substrate before it drips inside, so the wet ceiling is almost never under the failure. MRS traces the leak to its source, identifies why the membrane failed, and repairs with the correct system so it stays fixed — then flood-tests it.
  • How much does a roof leak repair cost?
    It depends on the source and extent of the failure, so MRS quotes after inspecting — the repair scope and method are written into the quote. Site visits are free, and MRS carries a 2-year workmanship warranty on repair work.
