Many owners believe that lower-cost waterproofing solutions should be fully evaluated before committing to major capital expenditure such as a new roof membrane.

Gardinia has spent thousands of dollars on multiple engineering reports concerning roof leakage over the years. A resident owner with approximately 50 years’ professional building experience inspected the roof and expressed the view that straightforward waterproofing repairs should be considered before major replacement works. A second independent builder reached a similar conclusion.

Owners should be given a clear comparison of available options, their expected life, warranties, risks and costs before any major commitment is made.

It appears that the roof membrane was replaced not much longer than 10 years ago, while a roof membrane could last 30 years or more.
