1 General remarksPreface Metal materials
The house is the focus of human experience. And yet, roofs came before wallssince roofs and roof coverings are as old as the hills. When human beings lived inprimitive caves they protected them with bark, leaves or straw. Long before thecoming of the Europeans, before the advent of western culture, human beings fromother societies built houses and equipped them with a roof. This protected fromthe whims of nature and hostile forces. The craftsmanship involved in coveringroofs has always been important. Metals are a historic building material that wasalready being used for technically and stylistically sophisticated buildings and forartisanship in the Bronze Age. The metal roof is rated highly in modern architecture,not least because of this.
Introduction

1.2 Products Materials
RIB-ROOF Benefit from a systemRIB-ROOF metal roof systems from Zambelli are an advancement in the traditionalhand-made standing seam system made as a result of technological progress inthe roll-forming technique. So-called sliding clips were developed from theconventional adhesives. RIB-ROOF is fitted without any perforations on the slidingclips designed exclusively for the system. The clips facilitate temperature inducedlongitudinal expansion of the profile sheets.
The two product lines RIB-ROOF Speed 500 and RIB-ROOF 465 in the standard overallwidth 500mm and 465mm (for exact specifications see Chapter 2 RIB-ROOF Speed500 and Chapter 3 RIB-ROOF 465), a wide selection of materials, colours andsurfaces as well as a full range of accessories, RIB-ROOF has the right solution forevery need. It is self-supporting and accessible and can consequently be laid onpurlin or on a full area support the scope of application ranges from single shelled,rear ventilated roofs with air insulation to thermally insulated roof structures withoutair insulation.
We will provide you with suitable proposals for solutions for roof refurbishmentswith business being conducted as usual in the building by using a roof span withRIB-ROOF on the existing roof surface. We have prepared individual design proposalsfor refurbishment of existing asbestos cement corrugated slabs or fibre cementslabs in particular. Please speak to us about it.
RIB-ROOF can be laid from a pitch of only 1.5. The lock seam profiles are producedas required in the desired sheet lengths. All sizes of roof area can consequentlybe laid from the ridge to the eaves, normally without a transverse joint.
Wide Variety of shapesRIB-ROOF profile sheets are available in conical, straight, curved or conicalcurved shapes. Sheets in extra long lengths from 33m upwards areprofiled and cambered on mobile roll-forming equipment directly onthe building site if required. In addition to the standard overall width,project-oriented dimensions are also produced on request.

Get moving now with RIB-ROOF!
RIB-ROOF saves valuable installation time. The profile sheets are simply clicked intothe system-specific retaining clips. Pre-assembly and alignment of the clips is justas unnecessary with RIB-ROOF as is seaming or flanging with special flangingmachines. Since flanging is not necessary with RIB-ROOF, it can be installed at lowoutdoor temperatures. The profile sheets are available ex works with chamferedor bevelled edges on the side of the ridge or eaves.
The full range of prefabricated elements facilitate flexible, efficient planning andfast, precise installation. All parts such as harness security system, snow fencesystems, skeleton steps and mounting bracket for solar module are installed onthe profile sheets without penetration.
Wide range of materials, colours and surfaces
RIB-ROOF profile sheets are available in a wide variety of materials and colours.You will find more information on the materials and colours in the summary onthe inside of the cover. All RIB-ROOF system components comply with class IIIcorrosion resistance in accordance with DIN 18807.

Minimum roof pitch in accordance with the general building inspectionlicence Germany:
Compliance with the following minimum pitches is necessary when using profiledboards as water carrying outer shell for roofs:
Minimum pitch of 1.5 (2.6%) for roofs without transverse joints.The required minimum pitch increases in roofs with transverse joints and or gaps(e.g. domelights) to 2.9 (5%).
The required increase in the minimum pitch for gaps in roofs e.g. for domelights may be waived if the following requirements are met:
Fully welded roof curbs are used.
The roof curbs are welded with the top shell of the roof to attain maximum density.
The certificate of suitability in accordance with the guidelines for welding supportingcomponents made of aluminium October 1986 version from the German Institute
for Constructional Engineering has been obtained for welding profiled boards orwelding to the profiled boards with an extended area of application for componentsunder 1.5mm thick.
The minimum pitch requirement is waived (at local level only) for the ridge areaif the roof elements in the area with pitches 2.9 (5%) are continuously (Note:for rounded roofs) arranged above the ridge.

Temperature induced thermal expansion of the materials is ensured horizontallyby the profiled form and vertically by the potential for movement of the profilesheets on and in the sliding clips.
Building- oriented production of the profile sheets from the ridge to the eaveswithout a transverse joint gives planners and roofers the greatest possible degreeof safety in the roofing trade.

Constructional physics Supporting structuresConstructional physics
It is not intended to deal with the installation of supporting or substructures forthe RIB-ROOF profile sheets in detail, suffice it to say:the guidelines for the installation of metal roofs, external wall coverings andplumbing works by the ZVSHK (Central Association for Sanitation, Heating, AirConditioning) and the relevant DIN norms make a distinction between the so-called
single shelled roof structures with an insulating layer (also called warm roof) orwithout an insulating layer and the double-shelled roof structures with rearventilation air circulation (also called cold roof).
Rear ventilated metal roofs have an air space with vents for the air to flow inand out on the eaves and ridge as a rule in order to be able draw off thehumidity that condensates on the cold metal back and is present in the air space.
A correct calculation depends on the structure and must be taken into considerationduring the planning and construction stages. Roof structures that do not adequatelyfacilitate natural air circulation must be equipped with mechanical ventilation. It
is well known that a number of factors may have an adverse effect on howventilation functions in a double-shelled roof structure. A single-shelled structurewith a vapour barrier (Sd value 100 m) without any levels of ventilation isconsequently recommended for buildings that are in the planning stage for economicreasons.
Insulated, unventilated roof structures require the vapour barrier to be attachedto the adjacent and rising components as well as roof penetrations so that it iswindproof and vapour proof.Distance profiles moulded from sheet steel act as a thermal bridge and reduce
insulation of the building. There is an increased risk of formation of water producedon thawing and resultant damage to the primary structure through corrosion. Adistance structure made of squared timber is thus recommended.
The results of calculations made by the Forschungsinstitut fr Wrmeschutz e.V.,clearly show the adverse effect of metallic distance structures. The With regard tothe U value calculation (formerly k value) of the entire roof structure, the effectof the retaining structure must be observed in order to obtain the thermal insulationlicence in accordance with the energy saving regulations.

In certain circumstances the guidelines of the ZVSHK (Central Association forSanitation, Heating, and Air Conditioning) recommend the installation of thermalinsulation with a protective sheet with open vapour diffusion on the thermalinsulation to protect it from humidity and secondary water produced on thawingwhich may form temporarily on the back of the metal during unfavourable weatherconditions. The need for precise fixing to the adjacent and rising components isunderlined.
There is no need to use these open diffusion protective sheets when the underlyingmineral thermal insulation is compressed by approx. 20mm.
There is additional information on this subject in Chapter 4.5 for against opendiffusion protective sheets or compressed thermal insulation.
The components made of various metals depicted in the table possible assemblyof metals must not come into direct contact when these metals show varyingdegrees of tension potential and the metal with the higher tension potential lies
above the flow direction of the rainwater which acts as an electrolyte.
When the RIB-ROOF profile sheets areassembled with other building materialsor components the following must beobserved to prevent contact corrosion.
Metals with a coating of paint, copperand stainless steel do not require any
special measures.
Aluminium zinc and bare aluminiummust be protected from stress causedby alkalis from mortar or concrete byinstalling dividing layers and byaggressive wood preservative or animpregnating agent.

The use of titanium zinc requires special attention.
Contact of titanium zinc with other building materials is dealt with at length in thespecialised literature (titanium zinc in civil engineering, published by Zinkberatung,Dsseldorf). Based on our many years of experience we would like to make acomment which is largely supported by the titanium manufactures. The effects ofthe atmosphere cause titanium zinc to form a natural protective layer on its surface.This layer is known as a patina. This is not possible in the required degree on theunderside of the roof with full surface support of the titanium zinc sheets sincethere is not sufficient air movement in this area. The secondary water formed bythawing on the back of the metal and the resultant permanent humidity lead tothe familiar titanium zinc damage.
For construction with titanium zinc and pitches 15 it is thus recommended thatthe underside of the profile sheets be protected with a lacquer coating or distancestructures be installed at the adjacent constructional level.

GENERAL REMARKSTRANSPORT AND
STORAGE OF MATERIAL
Transport of material StorageTransport Unloading
The profile sheets are transported by lorrywithout a crane. Access to the destinationmust be ensured. For extra long lengths(from approx. 33m upwards) productionis possible at the building site with mobileroll-forming equipment.
The material must be checked forcompleteness and damage immediatelyupon delivery.The consignments are marked with:delivering works profile designation licence number.
Complaints must be entered on the dispatch documents and our factory notifiedwithout delay.
The consignments of profile sheets (weight of consignment max. 1.5 t) must beunloaded with suitable lifting gear (crane or high-lift truck). Please ensure that thecrane or high-lift truck is made available in time once you have arranged thedelivery date with our works.
Delivery to the building site is generally made without providing a crane orhigh-lift truck.
A crane traverse (suspension
bracket) including fixed crane hookwithout harness, deadweight980kg, plus payload max. 1500kgwill be supplied if required.
Unloading using crane and crane traverse(suspension bracket). Harnesses minimumwidth of 10cm protect the profile sheets frommechanical stress and damage.

When cranes are deployed unloading must be done with harnesses. The edges ofthe profile sheets must be protected from mechanical damage. RIB-ROOF 465 withsheet lengths of approx. 12m for aluminium, copper and titanium zinc and approx.18m for steel require the deployment of traverses. Projections of more than 4.50mfor aluminium and steel, or more than 2.0m for copper and titanium zinc must beavoided. If the sheet lengths for RIB-ROOF Speed 500 are more than approx. 10m,they should be unloaded with a traverse.
Putting down and storage on the roof requires taking the load-bearing capacity ofthe substructure into consideration. The profile sheets must be secured to preventthem slipping and sliding down.
Storage
If the profile sheets are not going to be installed immediately, they must beadequately protected from weather factors. They must be stored in the directionof the profile to allow rainwater and secondary water produced by thawing torun off. If they are covered with tarpaulins, the latter must be windproof andbe adequately ventilated. Liability is not accepted for damage caused byimproper storage.

Material handlingDividing and cutting
Dividing and cutting the RIB-ROOF elements is done with suitable nibbling tools,sheet metal shears, compass saw or hand circular saw with a carbide cutting blade.The nibbling attachments for RIB-ROOF may be purchased from our range ofaccessories. The use of cutting-off wheels must be avoided; the resultant showerof sparks damages the surface of the material and may lead to corrosion damage.
Corrosion resistant materials (sheet steelwith aluminium zinc alloy or coil coatedand coated with paint) do not requiresubsequent treatment of the cut edges.
Drilling chips and sliced particles must beremoved from the surface immediately
as they can also cause damage to thematerial.
The different properties of the materialsmust be taken into consideration whenshaping flat sheets from RIB-ROOF basicmaterial. The table on the left shows theminimum bending radii of the metals.
Markings must not be made with sharp objects; we recommend using soft pencils.Table of minimum bending radiifor different metals

Maintenance tipThe agents used to clean the metal surfaces should not be aggressive butbiodegradable and environmentally friendly.Rinsing in cold water is generally necessary. Correction of damage to the paintworkmust be done with particular care. Paints for our standard range of shades areavailable on request but may differ slightly in hue. The manufacturer must beconsulted before damage to the zinc layers is treated. Minimal differences in the
painted and natural surfaces may result from the use of different batches, but arenot deemed to be a defect.
Joining technique welding solderingThe different properties of the materials must be taken into consideration when
joining metals (also see Chapter 1.3.1).The paint from coated aluminium strips must be removed before they are weldedor soldered. Once the work is completed the bare surface must be repainted with
the appropriate paint system.The technique for the joining methods is described in detail in the instructions foruse supplied by the manufacturers of the materials, e.g. Alcan aluminium, Hoesch sheet steel, VM zinc titanium zinc and KM-Europametall copper.
BondingAs the leaflet Bonding in plumbing technique by the ZVSHK (Central AssociationSanitation Heating Air Conditioning) in 53757 St. Augustin states, bonding of metalmaterials is also a possible alternative in plumbing technique. Single-component
polyurethane bonding agents are normally used in plumbing technique.

RIB-ROOF SPEED 500
As an advancement on RIB-ROOF 465 and RIB-ROOF 500, Speed 500 combines thebenefits of both metal roof systems: large distances between clips, self-supporting,accessible profiled sheets, ultimate in easy, quick installation
The lock seam profiles are produced to meet individual structural requirements inthe desired sheet lengths so that roof areas of all sizes from 1.5 pitch upwardsmay be laid without a transverse joint. Speed 500 is installed without penetrationand with its own system sliding clips. It may be laid either on purlins or on full-surface supports such as safe thermal insulation or shuttering for all standard typesof roof construction.
RIB-ROOF Speed 500 saves valuable installation time the profile sheets are simplypushed into the clips and swivelled. On a full-surface support 6 clips are laidsimultaneously with a clip at exactly the same distance apart. Moreover, there is noneed to perform time consuming beading of the profile sheets at the building site.
Wide variety of shapesRIB-ROOF Speed 500 is available in straight, conical, curved orconical curved profilesheets (see Chapter 2.4). Conical profile sheets may be finished with a minimumoverall width of 230mm and a maximum standard overall width of 500mm. Inaddition to the standard overall width of 500mm, other overall widths, e.g.333mm, 400mm or up to 600mm are produced on request (see Chapter 2.4.1).
Profile sheet lengths over 33m are profiled on mobile roll-forming equipmentdirectly at the building site. Curved profile sheets RIB-ROOF Speed 500: Curved(arched) profiled sheets are finished by forced arching at the building site ormechanical arching (by the works or at the building site) available from June 2005onwards. Installation and radii see Chapter 2.4.2.

Installation with sliding clips
Place the first row of clipsAlign the clips along the side of the verge flashing and fasten them with theapproved rivets or screws to the substructure. Additional pre-assembly is notrequired. The distances between the clips depend on building-specific data andwind loads (see Chapter 2.4). Please note: only use countersunk heads for clipfastening with screws.
Insert first profile sheet
Push the small rib of the ridge profile sheet into the clips. Then swivel the profileshee t down onto the substructure. Each profile sheet will subsequently be securedwith an anchor point to prevent it from sliding down. To bent the bottom chordupwards at the ridge and to bent it downwards at the eaves a bending tool isused. This can be done either in the factory or on-site.

Place the next row of clipsThe position of the next row of clips depends on the overall width of the profilesheets. This does away with the need for pre-assembly and alignment of theclips with a plumb line. Insert the sliding clips with a single hand movement intothe large rib. Then swivel, click into place in the rib and fasten to the substructure.
Insert next profile sheetPush the next profile sheet with its small rib under the clip and the large rib ofthe first profile sheet. Then swivel downwards and click into the clip. Timeconsuming beading of the profile sheets is not required. Speed 500 is reinforcedin the eaves area by joining the bottom flanges to an eaves angle. (Chapter 5.5)

Installation on full-surface support with clip border
RIB-ROOF Speed 500 may alternatively be installed on full-surface supports. Avariation in addition to the roof boarding is the high compressive strength mineralwool with high density top layer which improves the resistance to site work(application type DAA-dm according to DIN V 4108-10: thermal insulation).
Installation of the profile sheet may either be done on distance profiles whichcorrespond to the thickness of the thermal insulation or on the clip border structureprofiled or flat, which is fastened directly onto the support structure.It is vital to avoid gaps when laying the insulating boards. This finish is alsotransferable to RIB-ROOF 465 if so-called pressure distribution profiles are used.

Areas of application of the clip border finish flat or profiled RIB-ROOF Speed 500:
You always use the flat clip border on full surface supports, e.g. shuttering ornon-slip thermal insulation when the fastening screws can be placed in theerected clip and then in the subsequent webbed area of the profiled sheet andthe screw heads thus disappear into the hollow space of the web.
You use the profiled clip border on full surface supports such as non-slip thermalinsulation when the clip border must (also) be fastened between the clips andthe screw heads must disappear into the lateral cavity of the clip border. Foroptimal laying, the safe thermal insulation is milled out at the building site to
the exact fit of the geometry of the profiled clip border with a mobile millingdevice. Should you place an order, the milling device which resembles a lawmower will be supplied by us. If the profiled clip borders are needed on a lengthof more than 30 m, the clip borders have to be installed not one behind theother but moved a little bit or interrupted by a turned clip so that the expansionis guaranteed.
Possible subsequent opening of the RIB-ROOF Speed 500 profile sheets(e.g. for subsequent installation of roof penetrations) is done with the wedge madeof toughened plastic.

For smaller radii, conical curved and concave profile sheets please ask Zambelli.
For radii > 100 m the profile sheets are curved without a machine and fixed witha sliding clip. For radii under 100 m the turned clip has to be used (direction ofinstalling: right to left). As during the forced curving on-site the profile sheets haveto be pushed onto the radius, dents can sometimes not be avoided. The curvingby machine is the optical better solution.

RIB-ROOF 465
RIB-ROOF 465, is the proven metal roof system for over 30 years with large clipdistances, self-supporting and accessible profile sheets, quick, easy installation.
The customised lock seam profiles are produced in the desired sheet lengths sothat all sizes of roof areas from 1.5 pitch upwards may be laid without a transverse
joint.
RIB-ROOF 465 is installed without penetrations with its own system sliding clips.For all standard types of roof construction it may either be laid on purlins or fullsurface supports with safe thermal installation or shuttering.
RIB-ROOF 465 saves valuable installation time the clips are simply swivelled intothe profile sheets without any pre-assembly. Moreover, no time consuming beadingof the profile sheets at the building site is necessary.
Wide variety of shapes
RIB-ROOF 465 is available in straight or curved profile sheets (seeChapter 3.3): Profile sheet lengths over 33m are profiled on mobile roll-formingequipment directly on the building site.
If the inside micrometer for narrow radii and long profiled sheets is so large thattransport of extra longer widths becomes impossible, the profile sheets must becambered at the building site.
As a complete metal roof system, RIB-ROOF 465 offers a suitable solution for everyrequirement. The full range of accessories with useful articles that make the work
easier and save valuable time is shown on the next page.

Installation
Place the first row of clips
Align the clips (start or standard clips) along the side of the verge flashing andfasten them with the approved connecting elements (Chapter 1.3.2). Additionalpre-assembly of the sliding clips is not required. The distances between the slidingclips depend on building-specific data (spans, clip distances for enclosed hall-typebuildings see Chapter 3.4). Allowance must generally be made for increased wind
loads in the edge and corner areas.
Insert first profile sheet
The first profile sheet with its large rib is swivelled into the overlapping start clipand is clamped into the medium-sized rib on the clip. Alternatively, using thestandard clip press the large rib with the overlapping area together and clamp theprofile sheet with the large and medium-sized rib onto the clip from above (clicksaudibly into place). Secure the profile sheet with clamps, which overlap the external
rib, on the substructure (not necessary is the start clip is used).
Place the next row of clips
The position of the next row of clips depends on the overall width of the elements.To ensure that the profile sheets are laid parallel to and flush with the building,we recommend using a plumb line on the eaves and making regular checks of theconstruction width.

Click the clips into place in thelongitudinal bead of the rib and fasten them onto the substructure.
Insert next profile sheet
Click the large and medium-sized rib of the second profile sheet onto the firstprofile sheet and the exposed part of the clip. Using the zipper method, proceedfrom the eaves point to the ridge. Clicking into place is normally done by well-aimed accessibility (aid: wood border with milled groove).The moulded longitudinal beads ensure that the longitudinal joints are rainproofonce they have been clicked into place. Mechanical joining or manual processingis not required.

Installation technique Roof covering in generalPro contra open diffusion protective sheetor compressed thermal insulation
ZVSHK leaflet Ventilated and unventilated metal roofs manufactured from industrialpre-fabricated lock seam profiles
With the metal roof system RIB-ROOF you generally have the possibility of constructingboth the variation with the open diffusion protective sheet and the variation withcompressed thermal insulation. As you will gather from the ZVSHK leaflet Ventilatedand unventilated metal roofs manufactured from industrial pre-fabricated connectingend profiles, the ZVSHK (Central Association for Sanitation, Heating, Air Conditioningrecommends both types of construction. In individual cases, you can weigh thepros and contras of the two types and discuss them with the developers andarchitects. For economic reasons, the design with compressed thermal insulationhas also proved its worth during recent years in addition to the open diffusionprotective sheet which has been tried and tested for over two decades.
Pro contra open diffusion protective sheetRun off of water produced on thawing to the eaves on the protective sheet, alsoduring back pressure due to extreme ice snow conditions in the eaves
makes heavy demands on the layer to prevent potential water pocket formationCosts
Pro contra compressed thermal insulationless air space so formation of condensation minimised
Improved noise protection
Back pressure in the eaves possible during extreme ice snow conditions withpotential humidification of the thermal insulation (solution is a protective sheetwith a width of approx. 3m parallel to the eaves, or installation of additional rowsof snow fences in accordance with Practical Guide Chapter 5.9.)

Your RIB-ROOF regional sales manager will be pleased to answer individual queriesto assist you in choosing the protective sheet with open diffusion or the compressedthermal insulation.
Brief summary of the additional benefits of the RIB-ROOF metal roof systemrelating to the above topics:
RIB-ROOF metal roof system now gives you the practical choice of installing theopen diffusion protective sheet on the mineral wool since with RIB-ROOF the clipsare fastened from above through the protective sheet into the substructure andthe protective sheet does not have to be penetrated below the clips already installedby tearing the foil.
For non-insulated roofs (with vapour barrier Sd value >100m) you will obtainthe best U values with a distance structure (which is convenient forinstallation purposes), from lateral and counter lathing at a distance of1.19m in the normal area and intervening mineral wool insulation. The very
good U values attainable with in contrast to metallic distance structures havebeen documented in the scientific research conducted by the FIW Forschungs-institut fr Wrmeschutz e.V. Mnchen, (enclosed in your architect file).
Metallic distance structures with Z profiles or with system sliding clips requirecorresponding reinforcement of the thermal insulation (costs) in order to attain thesame U value.
Saving of energy costs with a wooden lathingAccording to the examination report of the FIW of 11 April 2005 you can save
about 1,300 per year and 1,000m 2 roof surface if you use a wooden distanceconstruction and not a metallic Z-profile. You can save energy costs of about
540 per year for the same surface against the metallic brackets which aregoing through the termal insulation.

3. The RIB-ROOF lock seam profile is more diffusion open than mechanically beadedsystems or conventional angled or double standing seam covers. The followingmedian values are given as Sd values in the corresponding study Determinationof Water Vapour Permeability by the FIW Research Institute, registered societyin Munich for RIB-ROOF Speed 500, median Sd value of 12.8m, for aluminium0.70mm; for RIB-ROOF 465 median Sd value of 25.7m, for aluminium 0.90mm(as a comparison: mechanically beaded system median Sd value of 30.6m, for
aluminium 0.90mm). Moreover, with RIB-ROOF the seam cavities and the opendiffusion roof edge son the ridge, eaves and verge flashing facilitate an additionalexchange of air and an additional diffusion effect as a result.
Laying technique
Important basic rules for installation
Installation must be halted during extreme weather conditions and individual profilesheets must be fastened or secured immediately. Since RIB-ROOF does not requirebeading, it may also be installed during low outdoor temperatures.
Please see the tables in Chapter 2.5 and 3.4 for accessibility of profile sheets duringinstallation (maximum span of accessibility determined by installation).
Inform other workmen before they access the roof that load distributing elementsmust be laid in the accessible areas in order to prevent deformations or damage
to the sheets. Joining the profile sheets to rising components necessitates bevelling the bottomflange prior to installation (available from the works), see Chapter ridge area 5.1.

Transverse joint
Profile sheet transverse joints are not required as a rule since longitudinalexpansion of the material is taken up by the fastening elements (clip). Forextra long lengths that are not to be transported by lorry (>33m), the sheetsmay be profiled at the building site (see Chapter 1.4.1 Transport).
If transverse joints are still required, welded finishes with aluminium profile sheetsare chosen as far as possible. In exceptional cases and only for pitches >7,transverse joints with tight rivets and sealing material are finished (in accordancewith the following illustrations); their use requires great precision.

The large rib on the profile sheets is cut off for RIB-ROOF 465at its exposed seam end at a 45 angle.
After installing the elements, the water carrying bottom chord must be bendedwith the bevelling tool or pliers (illustration above), to prevent penetration ofrainwater and snowdrift. This step must be carried out when rising components(e.g. walls, row of windows) are connected and before laying in any event.
Alternatively, the bending upwards of the bottom chord at the ridge can also becarried out in the factory.
The opposite expansion of the profile sheet and ridge cap require immediatefastening using indented sheets. These are aligned on both sides (saddleback ridge)or on one side (single pitch roof, wall or connection to the row of windows) witha line or distance gauge and fastened onto the structural ribs with blind rivets orself-drilling screws.

There are a wide variety of gutter solutions that are used in different countries andregions. It is not intended to present a detailed description of them here.
The gutter which is inserted externally is the simplest eaves construction. The classicgutter in semi-circular or box form is fastened to the eaves plank with the gutterhooks. The requirements for the installation technique in accordance with DIN 18339 plumbing have been outlined. For ventilated roof structures, construction of anair inlet opening (at least 4cm clear opening) below the eaves is recommended.Installation of profile fillers in the eaves area is only required in exceptional cases.
The eaves plate ( gutter inlet sheet) is the connection of the roof to the gutterand should be measured on a scale of 333mm.

Roof penetrations
Roof penetrations and their curbs are constructed manually according to the materialor welded soldered watertight. They require great care and expertise in plumbingtechnique.
As the leaflet Bonding in plumbing technique by the ZVSHK (ZentralverbandSanitr Heizung Klima) in 53757 St. Augustin states, bonding of metal materialsis also a potential alternative in plumbing technique. Single-component polyurethanebonding agents are normally used in plumbing technique.
Water drainage and longitudinal expansions of the profile sheets in the penetrationarea must be ensured by taking the appropriate steps. The height of the curbsdepends on the pitch, but is generally not less than 15cm.

Round roof structures are sealed with pre-fabricated conical connection pieces (tightrivets and silicon sealing, Soft or hard soldering, welding, bonding).
Top sealing is done with a collar which projects over the connection pieces.
The substructure must be temporarily protected with suitable materials (protectivesheets) when a connection is hard soldered or welded due to the fire hazard (wood)and damage.
