Dektite Roof Flashing for Metal Roof Penetrations
One pipe through a metal roof can turn a straightforward roofing job into a detail that deserves careful product selection. Bremick Roofing Sundries & Supplies bring together Dektite roof flashings, pipe flashing products & roofing finishing supplies for Australian roof penetrations, metal roofing, plumbing work & maintenance.
Whether the job involves a flue, plumbing vent, pipe or other compatible roof penetration, the flashing needs to work with the penetration diameter & surrounding roof profile. Explore Dektites for dedicated flashing options, or browse Weatherproofing Supplies when the roof detail calls for complementary weather-exposed products.
Roofing sundries may sound like the small stuff, yet penetrations are exactly where small details become important. A suitable flashing, compatible sealing method, correct fasteners & properly prepared roof surface need to work as an assembly rather than as unrelated products.
What Are Roofing Sundries & Supplies?
Think beyond roof sheets & screws & you'll find the products that help finish the awkward details.
Within this Bremick collection, the strongest product focus is around Dektite roof flashing plus roofing touch-up products for applications where the coating manufacturer permits their use.

Dektite solves a specific problem rather than acting as a generic patch. Bremick documents its Dektite range as EPDM boot flashings with flexible aluminium bands for waterproofing compatible flue & pipe penetrations through profiled metal roofs.
For sealing products used elsewhere around compatible roofing details, Roof Sealants & Adhesives provides the related category.
Why Use A Dektite Roof Flashing?
Cutting an opening through roofing interrupts the surface that was originally directing water down the roof.
A purpose-designed pipe flashing creates a transition between the penetration & surrounding metal roof. Bremick Dektite EPDM boot flashings combine a flexible boot with an aluminium band that can conform to profiled roofing.
That makes Dektite relevant to compatible:
► Plumbing vents
► Flue penetrations
► Pipe penetrations
► Exhaust penetrations
► Service pipes
► Duct-related penetrations
► Metal roof maintenance
► New roofing installations
► Retrofit roof penetrations
Australian metal roofs aren't uniformly flat surfaces. Corrugations, ribs, valleys & roof pitch all influence how the flashing base sits around the penetration.
Current Australian product results also consistently describe Dektite products around metal roofs, pipe penetrations & flexible aluminium bases, making those terms particularly useful when identifying the product needed for a job.

Common Applications
Picture the services emerging through a workshop roof & the reason for specialised flashing becomes obvious.
Bremick Dektite roof flashings can be relevant across compatible:
► Residential metal roofs
► Commercial metal roofing
► Workshops
► Industrial sheds
► Warehouses
► Garages
► Farm buildings
► Plumbing installations
► Mechanical services
► Vent penetrations
► Flue installations
► Roof maintenance projects
A plumbing vent generally creates a different sizing problem from a large exhaust or flue. Measure the actual outside diameter rather than relying solely on the nominal description of the pipe.
Retrofit work introduces another challenge because the penetration may already be in place. Bremick identifies its Combo flashings for both new-build & retrofit applications, while Premium flashings are identified for new-build applications.
Roof maintenance can expose problems well beyond the rubber boot. Check surrounding sheet condition, fasteners, sealing interfaces & water paths rather than assuming every leak originates from the most visible component.
Where inspection or installation requires appropriate access equipment, Roof Access Equipment provides the related category.
Which Roof Flashing Do I Need?
Start with the penetration itself instead of choosing a Dektite by base size or colour.

|
|
Is the job new-build or retrofit?
|
Influences flashing configuration
|
|
What roof profile surrounds the penetration?
|
Base must conform to the roofing
|
|
Where does the penetration sit on the sheet?
|
Ribs, valleys & laps affect installation
|
|
What temperature will the flashing encounter?
|
Material selection can depend on service temperature
|
|
Is the roof metal or another material?
|
Flashing needs to suit the roof system
|
|
What sealing & fastening method is specified?
|
Complete installation needs to follow product requirements
|
Size-led searches are common because Dektite selection revolves around the penetration range. Australian Dektite products are sold across numerous diameter ranges, from small service penetrations through to substantially larger pipes.
Don't import a size from another supplier's range into the job without confirming that the corresponding Bremick product is actually available & appropriate.
Product Selection Guide
Five checks can turn “I need a Dektite” into a much more useful product specification.
Measure The Pipe Outside Diameter
The tape measure should touch the pipe before the flashing packet is opened.
Establish the actual external diameter of the pipe, flue or service passing through the roof.
Check:
► Outside diameter
► Shape of penetration
► Existing fittings
► Insulation where relevant
► Clearance around the penetration
► Required flashing range
A nominal plumbing or duct description doesn't necessarily tell you the dimension the flashing must physically seal around.
Identify New-Build or Retrofit
An existing pipe already protruding through the roof changes how a flashing can be installed.
Bremick identifies:
► Combo Dektite — suitable for new-build & retrofit applications
► Premium Dektite — suitable for new-build applications
This distinction can quickly narrow the product family before more detailed sizing begins.
Study The Metal Roof Profile
Where the penetration lands on the sheet can matter almost as much as its diameter.
Look around the opening for:
► Corrugations
► High ribs
► Valleys
► Sheet laps
► Existing fasteners
► Ridge or edge proximity
► Nearby flashings
► Water-flow paths
Bremick's Dektite EPDM products use a flexible aluminium band designed to conform around profiled metal roofing.
For compatible roof fasteners used around roofing work, browse Roofing Nails & Fasteners.
Check Temperature Before Assuming EPDM
A hot flue creates a different service environment from a cool plumbing vent.
EPDM Dektite products have defined temperature limits, so applications involving elevated temperatures require the actual product specification to be checked.
Australian roofing ranges also include silicone flashing products for higher-temperature applications, but don't substitute materials purely because they look similar.
Confirm:
► Normal operating temperature
► Possible peak temperature
► Pipe or flue type
► Required flashing material
► Manufacturer's permitted range
Build The Detail Around Compatible Components
A flashing isn't installed in isolation from the rest of the roof.
Depending on the specified system, the penetration detail can involve:
Metal Roof → Pipe or Flue → Dektite → Compatible Sealant → Roofing Fasteners
Each component performs a different job.
Where broader roof-system materials are required, Roofing Materials & Sealants connects the flashing job with related products.

Existing services often make Combo particularly relevant because the flashing decision has to accommodate what's already installed. New construction gives the installer more freedom to coordinate flashing placement with the service penetration.
Premium remains a purpose-designed option rather than a generic upgrade from Combo. Choose according to installation type, dimensions & product specification instead of assuming the word “Premium” means it suits every application better.
EPDM Roof Flashing vs Silicone Roof Flashing
Temperature can change the material conversation before roof colour or flashing style ever matters.
EPDM is widely used for flexible roof penetration flashings across standard compatible service conditions. Bremick's documented Dektite building-product information specifically covers EPDM boot flashings.
Silicone roof flashings also appear widely in the Australian market for higher-temperature applications. Current Australian product listings, for example, distinguish silicone Dektites from EPDM versions by their higher documented temperature capability.
That doesn't make silicone automatically superior for ordinary penetrations. Select the flashing material around the actual service temperature, penetration & manufacturer requirements rather than treating temperature capability as a reason to overspecify every roof detail.
Roofing Touch-Up Products – Check The Roof Manufacturer First
A scratched finish can tempt anyone to reach immediately for a matching paint colour, but coated steel requires more caution than that.
Industrial Shed's Bremick roofing sundries range includes touch-up paint variations. Their suitability depends on the substrate, coating system & manufacturer's instructions.
Importantly, BlueScope does not recommend using touch-up paint on COLORBOND® steel because air-drying touch-up paint weathers differently from the factory-applied finish & can produce a visibly different result over time.
Before applying any touch-up product:
► Identify the roofing or cladding material
► Confirm the coating manufacturer
► Check that manufacturer's repair guidance
► Inspect the depth of the damage
► Remove swarf or contamination appropriately
► Determine whether the mark is cosmetic or exposes a larger problem
► Don't cover corrosion without investigating its cause
Colour matching isn't the first question if the coating manufacturer advises against field touch-up. Follow the roof manufacturer's current guidance rather than assuming the availability of a matching paint colour means it should be applied.
Building A Better Roof Penetration Detail
Follow the path rainwater will take & the surrounding installation starts making more sense.
Water moving down profiled metal roofing encounters the flashing base, fasteners, sealant interfaces & changes in roof geometry around the penetration.
A well-planned detail therefore considers:
► Penetration position
► Roof slope
► Rib & valley geometry
► Flashing base dimensions
► Pipe diameter
► Water path
► Sealant compatibility
► Fastener placement
► Flashing material
► Service temperature
More sealant isn't a reliable cure for poor flashing selection. The Dektite needs to fit the penetration & surrounding roof correctly before compatible sealant performs its intended supporting role.
Expert Tips
Stand downhill of the proposed penetration mentally before drilling anything.
Imagine where water will travel during heavy rain & whether the proposed flashing has enough suitable roof area around it.
► Measure actual pipe outside diameter
► Confirm new-build or retrofit installation
► Check Dektite diameter range
► Identify EPDM or other required material
► Review service temperature
► Inspect surrounding roof ribs & valleys
► Keep clear of problematic laps where practical
► Follow current Dektite installation instructions
► Use compatible sealants
► Use appropriate roofing fasteners
► Avoid distorting the flashing base with excessive tightening
► Inspect older penetrations during roof maintenance
A flashing that fits the pipe can still be wrong for the location. Base dimensions, surrounding roof profile & nearby obstructions need enough room for the product to be formed & secured as intended.
Maintenance inspections deserve a wider field of view than the boot itself. Examine adjacent fasteners, sealant, roof sheet, coating condition & evidence of water movement before deciding which component requires attention.
Working above ground makes product selection only one part of the job. Access planning & appropriate fall-protection requirements should be addressed before roof work begins.
