Aluminium valleys are one of those products that rarely get much fanfare on a roofing job, but get them wrong and you’ll know about it the first time it rains properly. These 2.4m aluminium valley sections are supplied in bundles of 10, making them well suited to roofing contractors working on multiple properties or anyone who prefers to keep a decent stock on the van rather than running back to the merchant halfway through a job.
Available in three widths — 12 inch, 15 inch and 18 inch — there’s a size here to suit most pitched roof configurations. The 12 inch width works well on standard domestic roofs with moderate pitch, while the 15 and 18 inch options give you more coverage where the roof geometry funnels a higher volume of water, or where you simply want a wider lead-in for easier tile bedding on either side.
Why Aluminium Valleys Work on Site
Aluminium is a practical choice for valley work. It won’t rust, it handles thermal movement reasonably well, and it’s considerably lighter to carry up a roof than lead. It cuts cleanly with tin snips or a straight cut with an angle grinder if you’re doing a lot of them, and it beds into position without the faff of dressing that lead requires. For new build or re-roofing work where a traditional appearance isn’t the priority, aluminium valleys are a time-efficient option that holds up well in service.
These valleys are suitable for use with most standard concrete and clay plain tiles, slates and profiled tiles, though as always the width you need depends on the pitch and catchment area of your specific roof. Buying in a bundle of 10 makes sense for roofers running full re-roof jobs, and at bulk trade pricing through DTS it keeps your material costs predictable rather than painful.
If you’re pricing up a job and need aluminium valleys in quantity, this is the straightforward way to get them on site without overpaying.
Pro Tip: When cutting aluminium valleys to length, score the cut line first with a utility knife and straight edge before using snips, this reduces burring on the edge and gives you a cleaner finish under the tiles.
Aluminium valleys are used on pitched roofs wherever two roof planes meet and water needs to be channelled away efficiently. They are commonly fitted during full re-roofing projects, new build work and tile-for-tile replacements where the existing valley material is corroded or failing. Suitable for use under plain tiles, natural slates, fibre cement slates and most profiled concrete tiles, they are a reliable choice for residential and light commercial roofing across the UK.

Available widths: 12 inch, 15 inch, 18 inch
Material: aluminium
Supplied in bundles of 10
Corrosion resistant
Not suitable for: Not suitable for use as a substitute for lead flashing in areas requiring a traditional or heritage-compliant finish. Not recommended for flat or very low pitch roofs where standing water could be an issue.
Fix aluminium valleys into the valley gutter before tiling begins. Ensure the underlying boarding or underlay is clean, dry and free from any sharp protrusions that could cause the valley to deform or puncture over time. Overlap successive sections by a minimum of 150mm, working from the eaves upward, and dress the edges lightly where needed to ensure water tracks to the centre rather than creeping under the tile edges.
Cut to length using tin snips for occasional cuts or an angle grinder with a thin cutting disc for higher volumes. File or deburr any cut edges before installation to avoid sharp edges causing tile damage or injury during fitting.
Select the correct width for your roof pitch and catchment area before ordering or cutting
Ensure valley boards or underlay are clean, level and free from protruding fixings
Start laying from the eaves and work upward toward the ridge
Overlap each successive valley section by at least 150mm to prevent water ingress at joints
Cut to length using tin snips or an angle grinder with a cutting disc
Deburr all cut edges before handling or positioning
Fix in place with clout nails or appropriate fixings at the edges, keeping fixings clear of the water channel
Bed tiles on either side carefully, ensuring edges direct water into the valley rather than underneath the tile margin
What width of aluminium valley do I need for my roof?
Width depends on roof pitch and the area draining into the valley. A 12 inch valley suits most standard domestic pitches with a modest catchment area. Go to 15 or 18 inch where you have a shallower pitch, a larger roof area draining in, or simply where you want more working room when bedding tiles on either side. If in doubt, go wider rather than narrower — you can always trim tile margins slightly but you cannot widen a valley once it's fixed.
Can aluminium valleys be used with all tile types?
They work well with the majority of plain tiles, natural slates, fibre cement slates and standard profiled concrete tiles. They are not the right choice where a heritage or conservation specification requires lead, and you should always check manufacturer guidance if you are working with a premium or specialist tile product that specifies a particular valley material.
These valley sections are manufactured from aluminium, giving a good balance of weather resistance, light weight and ease of workability on site. Aluminium does not corrode in the way that steel would, and it handles the thermal cycling of a UK roof environment without becoming brittle. The 2.4m length is a standard roofing module that minimises waste and simplifies transport and handling.
