No roof space access
-
Skillion roof construction prevents access
-
Access was never provided
Roof space – no insulation
-
Insulation was not a requirement when the house was built (or has never been installed)
-
Loose-fill insulation has been shifted by wind or activity by house occupants or tradespeople, or insulation has been removed when work done on the house
Roof space insulation has gaps, creases, folds or areas missing
-
Poor initial installation
-
Insulation has become displaced due to air movement/wind in the roof space/occupant activity – this typically occurs with loose-fill, blown-in insulation
-
Loose-fill, blown-in insulation has settled and is thinner than it was originally
-
Activity by house occupants or tradespeople has displaced insulation
Roof space – insulation is touching the flexible roof underlay
-
This is likely to occur at the edges of the roof, particularly with low pitched roofs, where roof framing does not have enough depth to provide space for the insulation
-
The insulation has become displaced due to air movement/wind in the roof space/activity by occupants or tradespeople – typically occurs with loose-fill, blown-in insulation
Roof space – insulation has settled or compacted
-
Loose-fill blown-in insulation settles over time
-
Items stored in the roof space have compressed the insulation
Roof space – insulation is wet
-
A leak through roofing, around a chimney, flue or other roof penetration, from an inadequately flashed parapet or an overflowing internal gutter
-
Leaking pipes or water tanks in the roof space
-
Moist subfloor air moving through brick veneer cavity where the cavity is open to the roof space and to the subfloor space
-
Moist subfloor air moving through an uninsulated framing space where holes were drilled in top and bottom plates to allow framing to dry when wet timber framing was used for construction
-
Moist air flow from kitchens and bathrooms into the roof space through wrongly installed ceiling vents or open recessed downlights
-
Kitchen and bathroom extractor fans discharging into the roof space
-
Aluminium foil used instead of a roof underlay, resulting in moisture condensing on the foil rather than being absorbed by the underlay
-
Moisture from the cavity of brick veneer-clad walls where the cavity is open to the roof space
Roof leaks (visible as wet framing or water path stains)
-
Cracked, missing or dislodged tiles or shingles, or corroded metal roofing
-
Roofing sheets do not have turn-ups to the top end
-
Missing nail heads or waterproofing washers
-
Flashing has lifted, corroded or been damaged

Roof space dampness
-
A leak through roofing, around a chimney, flue or other roof penetration, from an inadequately flashed parapet or an overflowing internal gutter
-
Leaking pipes in the roof space
-
Moist subfloor air moving through brick veneer cavity where the cavity is open to the roof space
-

-
Leaking roof
-
Copper-based treatment to framing and roof space moisture
-
Inadequate corrosion protection of fixings for the location
-
Salt laden air being blown into the roof space
Roof framing – borer
-
High moisture content of timber
-
Use of untreated timber or native sapwood timber
Rodents or birds in roof space
-
Holes large enough for rodents or birds to enter the roof space
Rafters or ridge beams sagging
-
Rafter spans too great for the timber size and/or roofing type, or roof framing has been overloaded
-
Poor quality timber, or cracked or broken timber
-
Timber has rotted due to roof leaks or high roof space moisture levels
-
Light roof cladding has been replaced with a heavy roof cladding
