What is barge flashing?
Barge flashing (also called barge capping) is the metal trim fitted along the sloping edges of a gable roof, where the roof sheeting meets the outer edge at the ends of the ridge. It covers and protects the cut edge of the roof sheets from wind-driven rain and lifting, while also giving the roof a finished edge. ClickSteel stocks it in both Colorbond steel Barge Flashing and Zincalume Barge Flashing, plus roll-formed profiles like the COLORBOND steel .40 Roll Top Barge, so you can match the flashing to your roof sheeting and colour scheme. It is cut to length and folded to the roof pitch, then fixed over the barge board or the last line of sheeting.What are the dimensions of barge flashing?
Barge flashing dimensions vary by profile, roof pitch and how much cover and overlap the job needs, so girth (the total width of metal folded into the flashing) and length are typically specified per order rather than fixed to one size. ClickSteel’s range, including the Colorbond steel Barge Flashing and the ZINCALUME .40 Roll Top Barge, is custom folded and cut to length on request to suit your roof’s pitch and barge board depth. Thickness is generally 0.40mm base metal thickness (BMT) for these roll-top profiles. Confirm the exact girth and length for your roof against the manufacturer’s flashing details or your roofing supplier before ordering.What is the minimum cover required for barge flashings?
Minimum cover for barge flashings is governed by AS/NZS 1562.1 and the roof sheeting manufacturer’s installation guidelines, and it depends on roof pitch, sheet profile and exposure to wind-driven rain, with steeper pitches and higher wind zones generally needing greater overlap. As a supplier, ClickSteel stocks barge flashing such as the Colorbond steel Barge Flashing and COLORBOND steel .40 Roll Top Barge cut and folded to the cover you specify, but the actual minimum for your roof should be confirmed against the relevant Australian Standard or your roofing installer’s specification, since requirements vary by region and wind classification.Is barge capping and flashing the same thing?
Barge capping and barge flashing refer to the same component, the metal trim that runs along the raked, sloping edges of a gable roof, and the two terms are used interchangeably across the industry and by manufacturers. ClickSteel lists it under both names, with options such as the Zincalume Barge Flashing and the COLORBOND steel .40 Roll Top Barge covering the standard profiles used on Australian homes and sheds. Whichever term your builder or supplier uses, the function is identical, protecting the exposed edge of the roof sheeting and giving a clean finish to the gable end.What is the difference between a fascia board and a barge board?
A fascia board runs horizontally along the eaves, the low edge of the roof where gutters are fitted, while a barge board runs along the sloping, raked edge of a gable roof at the ends. Fascia typically carries the gutter and gutter brackets, whereas a barge board is capped with barge flashing, such as ClickSteel’s Colorbond steel Barge Flashing or ZINCALUME .40 Roll Top Barge, to seal and finish the gable end rather than to hold water. Both are usually clad or capped in COLORBOND steel or Zincalume to match the roof and guttering.What is a barge on a roof?
The barge is the sloping edge of a gable roof at each end, where the roof sheeting terminates at the outer edge of the barge board rather than running into a gutter. It needs protection from wind and rain getting up under the last sheet, which is what barge flashing, or barge capping, provides. ClickSteel supplies this in Colorbond steel Barge Flashing and Zincalume Barge Flashing, along with roll-top profiles like the COLORBOND steel .40 Roll Top Barge, cut to length for gable roofs of any span.
