Wondering about requirements for weatherproofing or the effects of penetrations?


Clarifying environmental impacts on roofing performance with your clients?


Philip Beveridge, experienced roofing consultant, presented the QBCC Tradie Talks this month. The recording and slides are now available:

Professional and compliant roof design and installation avoids

- leaking

- condensation

- damp

- corrosion


Metal roofing defects are very common and are reported commonly to QBCC. Usually issues relate to

· Profile

· Roofing selection/ material selections

· Poorly installed flashings etc


Repair costs can be high especially when it involves damage to surrounding building elements.


Environmental effects of roofing and walling is key– the successful selection of materials depends on environment and location of each project.


Design the roof right (success from the get go)

- Consider water / rainfall intensity (305 is a key measurement – recent decrease) so the overall roof run can be checked, and roof profile can be correctly designed to ensure capability.

- In the design stage it is especially important to consider the thermal efficiency and specify the colour early on - the Icanz book (free handbook) satisfies BCA Section J requirements.
