Best barge flashing among these three listings
Updated: 23 October 2026
You want the best barge flashing you can order today, and the amazon.co.uk set in front of you is three rolls. Stars and a low shelf price both point at the wrong object if the gable needs a folded cover. Inside this set the only job anyone can win is a patch: lead, felt, a valley, or a gutter the listing actually names. The [barge flashing comparison](/hub/diy-supplies/barge-flashing) holds the three records. Prices are the shelf figures stored on 19 October 2026. We did not stick a roof, and a qualifying purchase can earn a commission at no extra cost to you.

The only job these listings can win
A barge, in the sheet-roof sense, is a 3 m piece of metal folded at 90 degrees, about 0.7 mm thick, with a wing of 150 mm or 200 mm. Nothing kept here is that piece. Bostik Flashband is bitumen tape. The Target Control roll is silver butyl tape. The Winfox coil is flat aluminium titled 0.2 mm.
If you are closing box profile at a gable, the winner is none of these, and the widths live on the barge flashing buying guide. If you are patching lead or felt that is still there, the three rolls are comparable.
Top pick for a lead or felt patch
The top pick is Bostik Flashband, 100 mm by 10 m, grey, at £13.34. amazon.co.uk shows 4.4 from 5,102 reviews. The bullets name repairing lead flashing, sealing valley gutters, and mending leaks in drainpipes and guttering. In the 50 review texts stored for this ASIN, people who had used Flashband before describe a seal on a cracked flat roof and around a stack pipe, after the release film was off and the strip was pressed. Bostik's UK technical sheet sets application at about +5°C to +30°C and expects a seam roller. That sheet is the maker's claim, not a head-to-head test against the other two rolls.
The weight line says 100 g against a 1.0 square metre roll, so do not trust the grammes. Paintability is asked and not answered. For a flat, clean, dry patch the listing names, this is the roll to open.
What the £11.39 roll costs per metre
The Target Control silver roll is £11.39 for 5 m at 100 mm, so about £2.28 a metre. The Bostik roll is £13.34 for 10 m, about £1.33 a metre. The lower ticket is the shorter roll. The silver roll is also 4.4, from 753 reviews, but the 50 stored texts are a poor match for a verge. Early comments cover a pond liner, a freezer drawer, and a small pipe leak.
The material line says ethylene propylene rubber and the adhesive line says butyl, and those fields are not reconciled. The upper temperature on the page is 45°C. Tack falling away as the roll is unpeeled is a repeated complaint, so the last metre can be less sticky than the first. Buy it for a short silver tape you can press by hand, after you have accepted that the reviews are often not roofs.
Skip the 0.2 mm coil for a barge
The Winfox coil is £14.99, titled 4 inches by 20 feet and 0.2 mm, with 4.8 from 12 reviews. One buyer used it on an outside roof. The same texts mention gloves, sharp edges, scissors that will not cut it, and a cut from a dented start of the roll. One review writes 4 inches by 20 inches, and the package line says 5 x 3 x 3 cm and 100 g.
Where NHBC Standards 7.2.20 uses aluminium as flashing built into masonry, the band is 0.7–0.9 mm. The coil is not self-adhesive. It can be a light offcut for a shed detail if you confirm the length on arrival and wear gloves. It is the skip for a gable cover and for a lead repair. If the question is whether tape may stand in for Code 4 lead, that fork is on lead flashing or Flashband.
Who should skip all three
Skip all three if you need a folded barge for profiled sheets, or if the gable is tiles or slates and the water is at the verge. Skip the coil if you wanted a self-adhesive lead repair, and skip the silver roll if you wanted reviews about roofs. The top pick remains Flashband only when the surface is a clean, dry patch the listing names.
Common questions
Why is 4.8 stars not the winner?
The 4.8 belongs to the Winfox coil and rests on 12 reviews. The title says 0.2 mm and 20 feet, while the package line says 5 x 3 x 3 cm and 100 g. A higher average on that count does not beat 4.4 from 5,102 on a tape whose listing names lead repair.
Will Flashband stay on a vertical wall?
The stored reviews do not support a blanket yes. One verified review, with the recommended primer, reports a lean-to that slipped after about four to five months and let heavy rain in. That is a single account. A vertical face needs a check after the first heavy rain.
Is the coil acceptable on a shed?
The bullets name sheds, and one stored review describes an outside roof. The edges are sharp, and scissors are reported not to cut it. Accept it for a small shed detail only after you check what arrived. Do not treat 0.2 mm as a barge on the house.
Does the top pick include a folded barge?
No. The top pick is grey bitumen tape, 100 mm wide and 10 m long. There is no 90-degree fold in the title, the bullets, or the reviews we stored. If you are covering the edge of a sheet roof, this roll is the wrong shape.
What must the page not claim about lifespan?
It must not turn one lean-to review into a failure rate, and it must not invent a year count the sources do not give. The silver roll's 45°C line is a listing cap. Bostik's sheet gives an application window that depends on conditions, not a count of winters.
