Bristile storyCompany DetailsThe Bristile StoryToday, that small roof tile company has developed into one of Australia’s largestsuppliers of concrete and terracotta roof tiles.In 2700BC the Chinese first developed the glazed terracotta roof tile and they have been a reliable and sought afterroofing product ever since. The refinement of concrete roof tiles into a long lasting and cost effective roofing materialhappened in the middle of the 19th century. The versatility of both products has seen them become popular in suchdiverse markets as Europe, North America and Asia.Terracotta tiles were first introduced to the Australian market in 1916. In 1929 Mr. Lance Brisbane established theterracotta division of our business in Perth, Western Australia. Thanks to Mr. Brisbane, from whom the company tookits name, and the hard work of dedicated employees through the years, the Bristile brand became synonymous withbuilding products of the highest quality. Concrete tiles were first marketed in the late 1940’s and roof tiles, whetherconcrete or terracotta, quickly became the roofing material of choice due to their durability, profile variation andselection of colours.In 1974, Besser Roof Tiles (as the company was then known) entered the Queensland market offering one tile profile ineight colours. In those days maximum output was 20,000 tiles per day. In time the company expanded into New SouthWales, building factories in Grafton and Sydney. The Pioneer group purchased the company in 1989 and oversawfurther development during the next decade including the incorporation of the famous Victorian brand Nubrik whichhad first made concrete tiles in 1972 under the Whitelaw Roof Tiles brand.Today, these various roof tile companies, which first started serving the Australian market over 75 years ago, havecombined. Now known as Bristile Roofing, we are one of the country’s largest suppliers of concrete and terracotta rooftiles, with a comprehensive range of more than 40 colours and seven profiles. Bristile Roofing is part of the nationalBrickworks group of companies which includes other famous Australian brands like Austral Bricks, Eureka Tiles Australiaand Auswest Timbers.There have been a lot of changes over the years, but one thing that has not changed is our desire to provide ourcustomers with the very best quality products and service. Our focus on quality gives us the confidence to provide awritten 10 year installation warranty on our concrete and terracotta product and a 50 year product warranty on ourconcrete range of tiles. Bristile’s La Escandella Collection of terracotta products are covered by our famous “Colour forLife” warranty that states they will retain their colour for life.For more information on any of our products please call 1300 274 784 or visit our website.016 Bristile Roofing

design considerationsRoof DesignDesign ConsiderationWhen designing new roofs Australian Standards AS 1170.2 and AS 4055 are to be considered, inconjunction with:a) The regional design wind speedsb) The terrain category of a building sitec) The National Construction Code (NCC)d) State and/or local statutory authority requirements and covenants. Exceptional considerations may apply to thesite in relation to items a), b) and c)The installation specifications given in this manual are based on a basic wind speed for greatest strength of 60m/s at aheight of 6m from ground level. Suitable for sites in Regions A and B. It is advisable to consult both your building engineerand local Bristile Roofing office in relation to designated cyclonic area installation specifications areas i.e. Regions C and D.This section will cover Bristile Roofing recommended installing specifications based on the design gust wind speed, as well as:a) Minimum roof pitch requirementsb) Maximum rafter length requirementsc) Batten requirements and rafter and truss spacingsd) Batten installing requirementse) Sarking installation requirementsSpecifiers are advised to determine local requirements before proceeding, noting that relevantlocal authorities may implement special specifications to the final structure.It is also advisable to consult your local Bristile Roofing office, as they may recommend installing specifications based onregional experience.Storm Water Drainage:The National Plumbing and Drainage standard AS 3500.3.1 should be consulted todetermine the best solutions for managing stormwater run off from a roof.Code Considerations:The design of a roof requires the consideration of many building codes andstandards. The following sections and tables summarise the major designrequirements applicable to roof tiles. These requirements are by no meansexclusive, as there may be any number of local regulative requirements andcovenants. Specifiers are advised to ensure they have fully determined the localrequirements.Standards:Bristile Roofing products comply with the following standard: AS 2049 Roof Tiles.Bristile Roofing fixing complies with the following standard: AS 2050 Installationof Roof Tiles. Bristile Roofing complies with the following standard when installingsarking: AS/NZS 4200.2 Pliable building membranes and underlays – installationrequirements.Wind Forces:Wind forces must be considered when designing or specifying roof structures androofing materials. The forces involved may take the form of positive or negativepressure (suction).The magnitude of these forces is affected by regional wind velocities, exposure andbuilding configuration. The methods for determining these are set out in StandardsAssociation of Australia Loading Code for Wind Forces AS 1170.2. As an extensionto this code, following Cyclone Tracy devastating Darwin in 1974 criteria weredeveloped for the design of structures including roofs. The resultant set of guidelinesis called Technical Record 440 (TR440) and is now deemed to be the standard fordesign of products for most cyclonic areas.020 Bristile Roofing

wind categoriesRoof DesignWind CategoriesThe pressure created by winds must be considered when specifying roof structures and roofing materials. Determining thewind force affecting a site at height is essential to pinpoint the desired level of security installation, as the negative pressureexerted to the leeward side of a pitched roof at 35m/s can be more than the weight of the tiles.High Pressure ZoneMedium Pressure ZoneThe following factors affect the magnitude of these wind forces: basic wind speed, direction, terrain and building height.Basic Wind Speed CategoriesAS/NZS 1170.2 and AS 4055 provides information on wind speeds commonly affecting different areas throughout Australia.Bristile Roofing recommends that you consult with qualified specifier to determine the wind category for your project.BASIC WIND SPEEDS IN DIFFERENT REGIONSREGIONS Vs (m/s) Vp (m/s) Vu (m/s)A 38 41 50B 38 49 60C 45 57 70D 50 69 85For detailed regional wind speedinformation refer to table 3.1 onpage 13 of AS/NZS 1170.2 Structuraldesign action - Wind actionsWEIPACOOKTOWNCAIRNSMAREEBABROOMEDERBYBURKETOWNTOWNSVILLE20REGION C0BOWENCHARTERS TOWERSPORTMACKAYHEDLANDMARBLE BARALICE SPRINGSROCKHAMPTONBUNDABERGREGION CREGION B25 0REGION A4MARYBOROUGHCARNARVONGASCOYNE JUNCTIONTOOWOOMBA BRISBANE25 0GRAFTONGLEN INNESMORAWAREGION B30 027 0GERALDTONREGION A1COFFS HARBOURREGION D30 0GREEN HEADPERTHDARWINREGION CKATHERINEREGION B142 o REGION BAustralian Territory Only11 oADELAIDECANBERRAREGION CSYDNEYREGION A2REGION A5(WITHIN 70KM OFMELBOURNE GPO)REGION A3MELBOURNEHOBARTRegions are marked with200KMthe letters A (A1 to A5) B, C50KMand D.

Roof DesignFixing Standardsfixing standardsBristile Roofing tiles are manufactured and tested to cope with a varied range of weather conditions throughout Australia.Factors affecting the design of your roof are as follows:Selecting the Roof TileThe depressions in the body of a profiled roof tile act as an unaffected watercourse quickly dispersing water from the roof.On flatter profiled tiles, these depressions are either less prominent or not featured. Therefore, water is more able to be blownacross the roof by wind, resulting in water following the tile’s under-lapping watercourse.Profile shape should be considered carefully, particularly on roofs that are built in exposed areas where high winds areprobable.The Pitch of the RoofThe pitch of the roof affects the force of gravity and when combined with wind forces dictates the pull of water from theroof. The greater the pitch, the more effectively the water will disperse, therefore the less the pitch the less effective the waterdispersal. Tiling is not recommended for a roof pitch below 15 degrees without special safeguards being put in place. AS2050 states where it is intended to fix tiles to roofs with a pitch of less than 15 degrees, the tile manufacturer’s advice shouldbe adhered to. Sarking is a pliable foil installed prior to fixing the roof battens. Sarking acts as insulation keeping your homecool and free from dust as well as acting as a secondary water catchment. Your Bristile Roofing representative should beconsulted when choosing the correct grade of sarking for your roof design. Table 7 (below) demonstrates the minimum roofpitch at which Bristile Roofing tiles are to be installed, showing each region with and without the need for sarking.Table 7: Pitch and Sarking RequirementsNSW VIC & TAS QLD SA WA Cyclonic AreaW/OutSark With Sark W/Out Sark With Sark W/Out Sark With Sark W/Out Sark With Sark W/Out Sark With Sark W/Out Sark With SarkConcreteHacienda 20 15 20 15 20 15 20 15 N/A N/A * 17.5Villa 20 15 20 15 20 15 20 15 N/A N/A * 17.5Yeoman (Shake) 20 15 20 15 25 17.5 20 15 N/A N/A * 17.5Yeoman (Shingle) 20 15 20 15 25 15 20 15 N/A N/A * 17.5Lodge (Striated) * 20 * 20 * 20 * 20 N/A N/A * 20Lodge (Smooth) * 20 * 20 * 20 * 20 N/A N/A * 20*Sarking required regardless of pitch.Note: Roofs with pitches of less than 20° with sarking installed require Anti Ponding Boards to be fitted.Concrete Roof Tiles| Technical Manual027

Roof DesignRafter Lengths and Pitchesrafter lengthsand pitchesThe minimum pitch recommended for a roof can be influenced by the water run off depth. Extremely long runsaccumulate water to a considerable depth at the bottom of the run, particularly at low pitches, and in heavy rainfallconditions. It is for this reason that Bristile Roofing recommends that any roof with rafter lengths in excess of 4.5 metresshould be built at a pitch greater than the minimum stated in Table 9 on page 4.7 of this manual. The specified pitchshould increase by 2° for every additional metre of rafter length.Informative Notes in AS 2050 “Installation of Roof Tiles”, state: “Long rafter lengths may require sarking to preventinundation of the roof. These lengths may vary according to the tile profile used, the pitch of the roof and the exposure.The manufacturer’s specification should be consulted.” Table 9 indicates the maximum rafter lengthsafter which sarking must be installed to the area of roof that exceeds the noted maximum length.Table 9: Sarking Requirements in Relation to Pitch/Rafter LengthROOF - DEGREES OF PITCHMAXIMUM RAFTER LENGTH WITHOUT SARKING (MM)≥18 < 20 4,500≥20 < 22 5,500≥22 6,000Concrete Roof Tiles| Technical Manual029

oof preparationrequirementsRoof DesignRoof Preparation RequirementsThe designer should ensure that the roof structure complieswith all relevant local and state statutory requirements andstandards where applicable.On delivery the principal contractor or owner shouldinspect the product for transportation damage. If there isany visible damage, a claim should be filed promptly withBristile Roofing or the relevant carrier. Examine each palletfor colour, profile and any damage. Check accessory itemsfor proper colour, profile and any damage. If there is anydamage to the tiles or quantities delivered are not correct,Bristile Roofing needs to be notified immediately.Suitable areas of the building site should be made availableand access should preferably be provided to all sides of theroof to allow efficient delivery and consequent loading ofthe roof.Prior to installation of the roofing tiles, the principalcontractor (builder) must ensure that other tradesmeninvolved in the construction have completed their work, i.e.bricklayers, carpenters, plumbers, electricians, and ceilingfixers for exposed beam areas.The Australian Standard AS 2050 Fixing of Roof Tiles(Appendix A), covers the need to define the responsibilities(commonly called “Work by other Trades’’ and “Informationsupplied by designer or builder”) of the main contractoror designer. The following list describes these areas ofresponsibility.Key Responsibilities:Unless otherwise specified in theroof contract the following must becompleted before roof tiles can beloaded onto the roof frame:1. Roof structure and rafters are to besecured, square and correctly braced2. Fascia boards installed at the correctheight with counter (tilt) batten(where applicable)3. Valley boards and valley irons installedin place4. Barge boards installed with counter(tilt) battens fitted (where applicable)5.

Refer to relevant state’s legislation to determine the most suitablehierarchy of control measures.Detailed control measures to prevent the risk of injury should be outlined in a workplace health and safety risk assessmentplan.Roof FramesLoad bearing internal partitions and wall frames are to be correctly framed and braced. Roofing structures are tobe square and straight and true to dimension specifications. The underside of the rafter or truss top chord should bediagonally braced. To assure normal rafter spacing along the eve creeper, rafters must be installed at hip corners. Topedges of hip and ridge boards should be level on their top edge. Slight deviations in a roof plane will be noticeable on afinished roof, and the tiler cannot correct this.Metal Roof FramesMetal roof frames must be installed using non-ferrous, stainless steel or steel nails/screws with suitable corrosion resistantcoating. Corrosive regions may promote unfavourable galvanic relationships in metallic substrate.Concrete Roof Tiles| Technical Manual031

exposed raftersRoof DesignExposed RaftersIf the roofing design includes exposed rafters or raked ceilings, ceiling linings, counter battens and sarking are to beinstalled on top of the rafters.

Roof DesignValleysvalleysTo ensure that this simple but critical area of the roof performs correctly, cooperation from several trade areas is essential.Firstly the carpenter must install the valley boards. These can be straight, or if available tapered hardwood boards with aminimum thickness of 19mm for roofs using 25mm battens and 30mm thick for roofs where 38mm battens are used. Boardsare fixed to the trusses or rafters with the thick edge facing into the centre of the valley.Now the fascia and gutter fixer fits the valley iron. He lays the iron onto the valley boards and then secures it with bent overnails. He “bird mouths” the end of the valley where it empties into the gutter and makes sure that it has sufficient projectioninto the gutter. If it is an up and over valley he will need to cut the two sides of the valley and rivet them together sealingthe join with silicone. (See illustration)Figure 3 Valley iron installationValleys rivetted and sealed at junctionFigure 4 Valley board installationTile BattenSarking installed undervalley batten, not toprotrude into valleySarkingValley ironTapered or straight valley board(thick edge faces in)Valley rafterValley batten only requiredwhen sarking installedConcrete Roof Tiles| Technical Manual033

fascia set upRoof DesignFascia Set UpIt is vital to ensure the fascia board height is correct to avoid the last course of tiles on a roof dipping. If a fascia batten isnot utilised or the fascia height is incorrect the last course of tiles will not be on the same plane as the remainder of the roof.The fascia board should be secured to the rafters by the top edge, 25mm higher than the tile batten thickness. Therefore, a25mm thick batten requires a 50mm distance between the top of the rafter and the top of the fascia board. This distanceis known as the fascia, tilt or bellcast height. Reduce the measurement of the fascia distance by 10mm if the roof pitch isless than 20 degrees. Alternatively, as the pitch increases toward 45 degrees, the fascia distance must increase too. If afascia board is not used, or fascia height is not sufficient, a batten referred to as a “fascia”, “bellcast” or “tilt” batten mustbe installed. Fascia batten height should be calculated using the same method, and installed on the top edge of the lowerrafter.Figure 5 Fascia bellcast detailMetal or fibre cement anti-pondingboard prevents sarking from pondingTile overhangbehind fascia50Tile battenTruss or rafterMetal fascia & gutter Soffit liningFigure 6 Tilt batten bellcast detailBottom course of tiles is supported on Tilt Battenand maintains the same plane as course aboveTile battenTruss or rafterTilt Batten by builder034 Bristile Roofing

Roof DesignFlashingsflashingsRoof flashings to tile roofs are to beinstalled by a qualified roof plumber,roof tilers are not responsible for thecorrect flashing of various roof features.The following details cover some of themore common design scenarios thatmay occur on roofs, they have beendeveloped over time and work well ifinstalled correctly. On some occasionscorrect installation of flashings willrequire coordination between the rooftiler and plumber.Flashings can be formed out ofmaterials such as Zincalume ® steel, softzinc, copper and lead. If lead is used itshould be a minimum of 20kg per m 2 .The lead should be sufficiently pliableto allow dressing down over tile profiles.Side flashings should be dressed to fitclosely into and against the tile profile,and be a close fit to the vertical wall.Flashing against vertical frameworkmust be sufficiently supported.When wall sheeting finishes above atiled roof a clearance gap is required.The distance of this gap must besufficient to cater for any battenthickness. The minimum clearancefrom the top of the rafter or truss andthe bottom edge installed flashingneeds to be 100mm. The includedtable details the clearance requireddepending on the size of battens beingused.Note: Lead flashings must not comeinto contact with Zincalume ® steel.On any roof where the roof is part ofa potable (drinking water) catchmentarea lead flashings should be painted.Dutch Gable FlashingFigure 7 Dutch gable installation detailFlashing to extend 300mmpast end of dutch gableBargeIf dry verge used it needsto spill out ontoflashing at this pointLead flashingturned up behindgable claddingLead flashing turned up10mm under hip to allowdirection of moistureto weep holesFlexible pointingFigure 8 Dutch gable installation detail (section)Tapered barge tileMetal bargeRafterTile battenGable claddingLead flashing75Lead to have a 75mmup-stand behind claddingClearance RequirementsCLEARANCEBATTEN THICKNESSTile battenRafter125mm138mm25mm38mm150mm50mmConcrete Roof Tiles| Technical Manual035

laying tilesInstallationLaying TilesSarkingSarking is a reflective, water resistant membrane that isinstalled between the top chord of the roof truss or rafterand the roof battens. It has a number of benefits the mostimportant of which are, the provision of a reflective barrierthat minimises heat transmission into the roof space, and as awater resistant membrane that provides a secondary barrierto water entry.A number of circumstances which dictate the use of sarkingas a protective measure against damage, irrespective ofroof pitch are listed below.» Where local regulatory authorities require the use of sarking» Where extreme weather conditions are probable i.e. clifftops, open exposed sites» Bushfire prone areas to prevent flying embers entering theroof space.» Mansard roofs.» Where design wind velocities exceeds 41m/s (ie. Greaterthan C1 or N3).» Where run off from a high level gutter or valley dischargesonto the roof, the roof should be sarked from the point ofdischarge down to the eaves gutter. Minimum width 1.8metres on either side of the discharge point. Alternativelylead flashing sufficient to cover the spreader dischargepoint can be fitted.Note: Ideally the National Plumbing and Drainage standardAS 3500.3.1 should be consulted to determine the bestsolutions for managing stormwater run off when the roof isbeing designed.» At any change of roof pitch greaterthan 6° and extending from there to the eaves gutter.» Where radiant heat is a problem and sarking is used tocontrol it.» Long rafter lengthsLayingSarking should be laid with the reflective side face down.Over-Lapping SarkingSarking should overlap at least 150mm, with the upper layeron top of the lower layer of sarking. The end of a roll ofsarking, should have overlapping layers at least one rafterspace in length. Sagging should not occur more than 40mmbetween rafters.Obstacles in the RoofHot FlueSarking should be cut back to create a clear space of 50mm.PenetrationsWater should be diverted from the roof by turning up andsealing sarking at any roof projection. In the case of a fasciabatten being used in place of a fascia board (and there is nogutter), the sarking material should be neatly trimmed to theoutside edge of the fascia batten.Use of Security PadsThe use of security pads or anti-flap pads is recommended toavoid constant flexing and to increase the life of the sarkingmaterial. Install security pads in a staggered pattern undereach second row of battens between each pair of rafters.Sarking at EavesSarking should extend over the fasciaboard by a minimum of 25mm and a maximum of 50mm toallow for optimum water run off.Sarking SupportApproved anti-ponding board is preferable on roofs with alow pitch, in accordance with regional specifications. (Makereference to page 6.14 of this manual). Adequate reinforcementof the sarking, where rafter centres exceed 600mm. Usingheavy grade sarking or supporting the existing sarking becomesmandatory where the rafter centres exceed 900mm. Installationof sarking support or safety mesh is performed by other trades asreferred to in AS 2050 Appendix A.Sarking at ValleysSarking is secured by fixing a valley batten parallel to thevalley gutter. The sarking should either overlap the valleyby less than 25mm or be cut at the valley batten. If sarkingprojects too far into valley the roof is likely to leak.048 Bristile Roofing

laying tilesInstallationLaying TilesConcrete Tile Batten Set OutAll Bristile Roofing tiles are designed to be consistent in dimension, which allows for easy set out. Concrete tilescan be installed with a variable head lap which allows them to be fitted without the need to cut the top courseof tiles. Terracotta tiles though, have minimal head lap tolerances and designers should ensure that the rafterlengths work full tile courses wherever possible. The information below gives a basic understanding of the tile setout procedure. Contact your nearest Bristile Roofing office for more detailed coursing information if required.Concrete Tile Batten Set OutProcedure:Correct spacing of tile battensis essential to obtain a uniformappearance of the finished roof.The following procedure is followedwhen setting out the roof inpreparation for tiling:1. The first set out nail is nailed at thefront edge of fascia board or tiltbatten, point “A”. The next set outnail is positioned to the undersideof the first batten, point “B”.Required spacing is determinedby using the first courseset out dimension noted in the TileGauge Ready Reckoner found inthe Bristile Roofing Specificationand Installation manual.2. The top batten set out nail positionis also noted in the Tile GaugeReady Reckoner and is measuredfrom point “C” which is the apexof the truss or ridge rafters.3. A measurement is made betweenpoints “B” and “C” and is thenreferred to the Tile Gauge ReadyReckoner which confirms thenumber ofcourses required to cover thenominated rafter length.4. The process is repeated at theother end of the roof.5. A chalk line is snapped across thetop of the rafters at each gaugemark.6. A set out nail is fixed at eachbatten rafter/truss crossing.7. The battens are then laid out onthe set out nails ready for finalfixing.Figure 33 Concrete tile batten set out procedure sectionUniformspacingas per tableA B CFirst (gutter)course set out asper tableTop batten set outas noted on the TileGauge ReadyReckonerNote: If there is significant thickness variation insupplied battens then set out should be from thetop of the batten.Roofs installed in Victoria are also set out from thetop of the batten.050 Bristile Roofing

InstallationLaying Tileslayng tilesLoadingBattening and sarking of the entire roof must becompleted before tiles are loaded onto the roof. Inbuildings where the rafters are internally exposed, orthe length of the truss top chord of rafter exceeds 6metres, tiles should be loaded onto the structure fromeach side to ensure that their weight isevenly distributed.First CourseThe first course of tiles should be positioned to provide anadequate projection over the fascia and into the gutter.For Bristile profiles this projection is normally 50mm.Note: Roman and Swiss terracotta profiles will requirea 60mm projection. Due to this requirement the gutterwidth should be considered when using these profiles.LayingTiles are to be laid and secured in accordance withAS 2050 “Installation of roof tiles”. All courses should bealigned horizontally, vertically and diagonally to ensurea straight finish at the roof edge and to achieve goodroof aesthetics.BlendingLayout is crucial due to the varying shades of colourwhich are a feature of terracotta tiles. Numerous tilecolours in blended roofs involve the mixing of many tileshades as they are laid. A visual inspection of the roofshould be carried out approximately 75 - 100 tiles into theinstallation to check courses and even distribution. Visualinspections of the roof should be repeated at regularintervals during installation. The same method should beemployed when blending some concrete roof tiles.Concrete Roof Tiles| Technical Manual051

securing of tilesInstallationSecuring of TilesTile ClipsBristile Roofing products are secured to the roof frame using a number of purpose made clips which make up ourclipping system. These various clips are designed to fix different Bristile Roofing profiles and accessory fittings in a range ofinstallation situations. All clips have been fully tested to comply with relevant fixing standards and are to be installed as permanufacturers specification to ensure the performance of the installed roof.Included below are a series of illustrations which detail how and where the main types of tile clips are fitted.NailsNon-ferrous or galvanised 2.8mm diameternails, of sufficient length to pierce the raftera minimum of 15mm should be used. Timberrelevant nail requirements and wind loadingsare specified inTable 7 on page 4.6 of this manual. The useof standard and heavy duty clips, eaves tileclips, screws and adhesives are offered inBristile Roofing’s security fixing system. Furtherrelevant information can be found in Section2.4.2 of AS 2050.Steep and Vertical PitchFor roofs pitched between 40-70 degrees alltiles must be mechanically fixed. “Mechanicalfixing” is achieved by nailing, screwing orclipping every tile. The method used is oftendictated by the regional authority andthey should be consulted during the designprocess. Clips are the preferred method ofmechanical fixing where there are extremeconditions. If the roof has a greater pitch than70 degrees it must be double mechanicalfixed and sarked.Figure 38 Ajax wire clipFigure 39 Ramlat clipFigure 40 Elabana clip052 Bristile Roofing
