The purpose of roof outlets is to provide effective drainageof rainwater. Selection of roof outlets is usually the
responsibility of the specifying engineer conversant with theroof construction, roofing finish, drainage system anddesignated function such as a garden or parking.Some of the factors that should be considered when selectingroof outlets are:
BUILDING REGULATIONS / STANDARDSNational and local regulations must be complied with inmatters concerning drainage of rainwater.
ROOF CONSTRUCTIONRoof outlets are not multi-purpose, versions are designed foruse with specific types of roof construction. The depth of thestructural slab, thickness and location of insulation, and thetype and location of waterproofing membrane are factors tobe considered.
FLOW RATEThe quantity and types of roof outlet to be used in a givenapplication must be related to the roof area and expectedvolume of rainwater to be drained.Flow rate is the amount of water (litres/sec) a roof outlet willdrain at a given head; it is influenced by several factors:grating free area, sump capacity, design of the roof outlet,outlet size, and accessories such as gravel guards and filterbuckets.Flow rates of Wade roof outlets have been established by fullscale tests, at various heads of water. Results are shown onpages 27 to 29.
LOAD RATINGIt is essential that roof outlets withstand expected loads. ThisTechnical Handbook shows the load rating class for eachgrating or roof outlet assembly, based on BS EN 1253, as follows:
K3 - Areas without vehicular traffic, such as balconies,terraces and roof gardens.
L15 - Areas with light vehicular traffic.
M125 - Areas with vehicular traffic, such as car parks, factories andworkshops - not including light commercial vehicles or heavy wheel loads.
PIPEWORKThe type and size of pipework in a given installation isfundamental to the selection of roof outlets. Wade roofoutlets can be connected to all pipework in general use;certain bodies are for direct connection to pipework, othersrequire the use of spigot adaptors or proprietary couplings.
THERMAL INSULATIONTo prevent condensation in roofs of heated buildings wherethe relative humidity may be expected to rise above 40%, itmay be necessary to install additional insulation around roofoutlet bodies. In applications subject to heavy snow or icingup, it may be desirable to include trace heating.
APPEARANCEWhilst of pleasing appearance, gratings are designed to berelatively inconspicuous when installed. For areas where abetter class of finish is required, some products are availablemade of nickel bronze.
ACCESSORIES AND VARIATIONSStandard optional items are readily available, such as filterbuckets to intercept debris, gravel guards, bearing pans tospread the load over a large area, and underdeck clamps tosecure bodies.Custom made products can be manufactured for non-standard applications.
MATERIALS AND FINISHES Strength, corrosion resistance and appearance are importantconsiderations when selecting roof outlets.
CONSIDERATIONS WHEN SELECTING ROOF OUTLETS
4
Materials and finish of Wade roof outlets, described below, areselected to provide lasting performance and to blend withsurroundings.
CAST IRON - BS EN 1561
Used for bodies, membrane clamping collars,extensionsand spigot adaptors.
A widely used metal in the drainage industry, its resistance tocorrosion permits extended use under extreme conditions.Castings are coated with a high grade lacquer paint, appliedby full immersion dip, to provide internal and external surfacecoverage. Paint will gradually wear off and is replaceable;oxidisation (surface rusting) is a natural process which doesnot weaken the material.
DUCTILE IRON - BS EN 1563 + 1564
Used only for gratings.
A casting with the ductility of steel, yet with more than twicethe tensile strength of cast iron. A zinc anti-corrosion coatingis applied by sherardizing.
5
MATERIALS
CARE AND MAINTENANCEThe products require the minimumof maintenance, but periodicinspection should be carried out toensure that roof outlets are freefrom gravel, leaves and otherdebris which could impair theperformance of the system. Castiron parts should be repaintedevery five years.
STAINLESS STEEL - AUSTENITIC GRADE 304
Used for gratings, gravel guards, filter buckets and allfastenings.
A corrosion-resistant metal containing significant amounts ofnickel and chromium.
GALVANISED MILD STEEL
Used for adjustable bearing pans and raising tubes.
A cost effective, corrosion resistant material.
CAST ALUMINIUM - LM6
Used for parapet gratings.
An alloy chosen for its chemical resistance and durability.
GUNMETAL - BS EN 1982
Used for downspout nozzles.
A cast alloy suited for finished areas where the rich, bronzecolour complements the decor.
NICKEL BRONZE - BS EN 1982 Satin finish
Used for gratings
A cast alloy which will maintain its lustre when subjected to theabrasive polishing action of traffic.The satin finish produces a fine grain effect which blends wellwith walls and floors.
POLYCARBONATE
Used for domes
A polycarbonate/ABS blend which offers durability, highimpact strength and long term resistance to ultraviolet light.
PVC
Used for body versions for use with PVCsingle ply membranes.
This material enables a waterproof joint to beproduced on site.
ABSUsed for spigot adaptors
Wade designs and manufactures roof outlets for use with specific types of roof
construction, worldwide.
This Technical Handbook includes ranges of standard products which are generally
available ex stock.
Custom made products and accessories can be designed to suit particular
applications. Please contact our Technical Services Dept for details.

Flow rates of Wade roof outlets have been established by full-scaletests. The values shown in graphs on pages 27-29 are 75% of suchtests.The graphs show, for given heads of water, flow rate (l/s) and areadrained (m2) at a rainfall rate of 75mm/h** or 0.021 l/s per m2.*
** Rainfall Rate - BS 636775mm/h has been used as previously recommended in BS 6367(withdrawn September 2000).Area drained [A] at a different rainfall rate [R] can be calculated byusing the following formula.
A (m2) = 75 x a (m2 @ 75mm/h)R (mm/h)(a: area drained, obtained from appropriate graph.)
For assistance please contact our Technical Services Dept.
Note: Our CD-ROM and website electronic catalogues include area/rainfall calculators based on the above formulas.

FLOW RATES
*Rainfall Rate - BS EN 12056 -30.021 l/s per m2 equates to 75mm/h, as previously recommended inBS6367 (superseded by BS EN 12056-3:2000).BS EN 12056-3 uses rainfall charts which provide more localiseddata given in l/s per m2.To calculate the area drained [A] for a specific rainfall rate [R] (l/sper m2) use the following formula.
A (m2) = 0.021 x a (m2 @ 0.021 l/s per m2) R (l/s per m2)
(a: area drained, obtained from appropriate graph.)

INSTALLATION GUIDELINES
1. Check Dimensions
Prior to installation, check height of
components to ensure compatibility with
roof build-up, making allowances for the
membrane thickness.
3. Install Body
Install body such that flange is flush or
sub-flush with roof deck. Ensure body is
fixed securely, either bonded or clamped
to the deck if not cast-in.
Note: Membrane flange level is
determined by roof build up.
4. Dress Membrane and Clamp
Refer to membrane manufacturer’s
instructions.
Prepare flange of body with suitable
primer and apply membrane, dressing
over flange and into sump of body.
Position membrane clamping collar and
secure to body using fixings supplied.
5. Install Insulation
Install any intermediate roof build-up
(e.g. insulation) around outlets.
6. Fit Grating. Apply Finish
Fit dome/grating using height
adjustment where applicable to ensure
grating is flush with roof finish.
Apply roof finish around grating.
GeneralThe design of the layout of roof outlets should be in accordance with the recommendations given in BS EN 12056:3.Wade roof outlets should be placed at the roof low points to allow efficient flow of water to the outlets.Illustrations of typical installations are given in each section of this handbook.
2. Fit Spigot. Check Outlet
Where applicable, screw spigot into
body, using a suitable sealant to ensure
the joint is watertight.
Position body in roof deck and ensure
that outlet is accessible for pipework
connection.
