Mystery Solved – Tracking Down a Tricky Roof Leak in Greenwood

by | Jun 19, 2025

Project Overview A Greenwood homeowner was puzzled by water appearing in their patio area with no obvious source. They called PGWA to get to the bottom of this mystery leak that was threatening to damage their outdoor entertaining space.

Finding the Leak

Water leaks can be sneaky, and this one was no exception. The homeowner could see water damage in their patio but couldn’t pinpoint where it was coming from:

  • Hidden water source making it difficult to identify the problem
  • Potential structural damage if the leak continued unaddressed
  • Ruined outdoor space that the family loved to use for entertaining
  • Growing concern about what other damage might be happening out of sight

Sometimes the most frustrating problems are the ones you can’t see – but that’s where our expertise really shines.

How fixed the leak

At PGWA, we know that finding the source is half the battle. Our thorough approach uncovered the real culprit:

  • Comprehensive roof inspection to track down the mystery leak
  • Diagnosis – discovered a severely rusted valley tray with multiple holes
  • Complete valley tray removal of the deteriorated component
  • Quality replacement installation with materials designed for Perth’s conditions

Our team worked methodically to not only fix the problem but ensure it wouldn’t happen again.

The Happy Outcome The mystery was solved and the problem eliminated:

  • Leak completely stopped – no more water damage in the patio area
  • Root cause addressed – replaced the failing valley tray entirely
  • Improved water management – new valley tray handles Perth’s heaviest downpours
  • Peace of mind restored – the family can enjoy their patio space without worry

Our aim: “Figure out where that leak was coming from, so the homeowner could have peace of mind when the next downpour rolled around. They can now use the patio again without worrying about water damage.” – Gregg Harrison
