ROOF SUPPORT
SERVICE SPACINGBattens Not greater than 800mm for any roof
his degree of support is required to provide adequate long term support of the sheets where theyare subjected to maintenance traffic as per manufacturer’s foot traffic design guidelines.
SEALANT
SERVICE JOINTING METHOD
(Silicone) To be used only to seal lap joints and should not to be used in filling gaps as per manufacturer’sinstructions.
Membrane Roofs
Three layer torch on polyester reinforced bitumen based sheet is the preferred system, with a mineral chip upper surfacewhere directly exposed to traffic and weather. The bottom layer should be a vented sheet where there is a likelihood ofresidual moisture in the substructure.
The membrane should be provided with a means to vent the substrate moisture either at its perimeter or with vent cowlsspaced across the roof area.
Slate roofs
Slates should be pre-drilled, not punched, and should be fixed with copper clouts which fit snugly into the hole. Copperhooks or straps should be used to secure the last few slates where finishing off an area of roof.
2. Specific Design Requirements
2.1 SARKING, SUB DECKING AND INSULATION
Slate and Tiles
Where slates or tiles are fixed over a timber, plywood or compressed sheet sub-deck the roof should have sarking and thespace between the sub-decking and the roof covering allowed to ventilate and to drain condensation water to a gutter.
Copper roof sheeting should be separated from its supporting deck with a layer of polyester reinforced bitumen sheet

Roofing_and_Penetrations_2009_version_1_with_amendmentsJL.doc Page 4 of 12
Insulation and Condensation Control
All new and refurbished roofs shall achieve a system thermal resistance level (R-value) of not less than 2.5 for both upwardand downward heat flow.
2.2 PENETRATIONS, FLASHINGS, PLANT AND COMMUNICATIONS EQUIPMENT
General
Consultants refer to ‘Appendix C: Detailed Drawings ’ at the end of this document, for selection of most appropriate detail orspecify alternative to the sub topics below.
Penetrations
Penetration of the roof covering should be avoided wherever possible by attention to the location of equipment and therouting of services lines.
When penetrations cannot be avoided they should be grouped and arranged in an orderly fashion to minimise the numberof penetrations of the roof, and detailed in accordance with the standard detail methods.
Penetration Flashing
Sheet flashings on slate or tile roofs should extend up the roof from the penetration to beneath the next tile/slate joint.Where this distance is less than 200mm the flashing shall be extended a further full tile/slate. In each case the flashing isto be folded over at its top end and dressed under the tile/slate.
Wall penetrations shall be set out so as to finish clear above the line of any perimeter roof flashing.
Individual pipe flashings (Dektite)
'Dektite' or 'Rooftite' are used on a profiled metal deck roof, they shall be used in conjunction with a flat sheet metal coverflashing as indicated on Detail 34 & 35 of Appendix ‘C’ of this document.
Only one Dektite (or equivalent) shall be used for one pipe / conduit that penetrates the roof.
The university will not accept fluted flexible electrical conduit with this type of flashing as water travels down the spirals ofthe conduit and by-passes the flashing. Therefore only smooth surfaced, preferably round, elements should be flashed inthis way.
2.3 FASCIAS, SOFFITS, CAPPINGS
To be painted as per USYD Finishes for rendered walls.
If coverage is needed in lieu of painting then the minimum gauge of materials should 0.60BMT for cappings, flashings,trims and the like.
2.4 SEPARATION STRIPS, EXPANSION JOINTS
Movement
Roofs are almost invariably constructed of a number of different materials which may adjoin or overly one another. Eachmaterial will have its own physical properties, including the degree to which it will move over time with changes intemperature and moisture. Wherever two different materials meet or overlap they should allow each to move independentlyof the other. This needs to be achieved without compromising the primary function of the roof which is to exclude rainwater.
Galvanic Separation
Dissimilar metals shall not be fixed in contact with one another, or where rainwater may run off from a nobler to a lessnoble metal. Mechanical fixings shall be made of the same metal, or a metal of equivalent nobility, as the material throughwhich they are driven wherever practicable;

Roofing_and_Penetrations_2009_version_1_with_amendmentsJL.doc Page 5 of 12
Where contact between dissimilar metals cannot be avoided, suitable galvanic separation materials shall be placedbetween those metals to eliminate direct contact. Separation materials should be weather resistant, UV stable, durable andchemically inert, and might include rubber, neoprene, some sealant materials or commercial grade adhesive tapes;
Dissimilar metals should be physically separated from one another to prevent the more noble metal from promotingcorrosion of the less noble metal. This separation should also eliminate situations where rainwater will run off a more noble
metal onto a less noble metal.
Examples: Lead and copper flashings should not be used above or in contact with steel or Zincalume roofing;Brass or steel screws should not be used for aluminium roofing.
2.5 ROOF SAFETY SYSTEMS
Introduction
Where possible, roof safety should be achieved through the provision of suitable barriers at the edges of roofs, toprevent a fall. Edge barriers might take the form of guard-rails, parapets, adjacent walls, other roofs or the like, or acombination of the above
Where the particular roof design does not provide edge barriers, the safety of persons having access to the roof shallbe achieved through the use of suitable harness based systems;
Static line safety systems are generally preferred to individual anchor point systems as they provide greater flexibilityof movement for maintenance personnel. Combinations of static line and individual point systems may be acceptableto achieve full coverage of roofs.
Provide Safety Mesh to comply with AS 4389 for flat roofs.
The University will not accept surface mounted roof anchors.
