Where two roof slopes meet, all the water from both of them runs down one metal channel. That is why valleys rust out long before the tiles around them wear out, and why a rusted valley shows up as a stain on the ceiling directly under the join.
A valley tray is doing the hardest work on the roof with the least attention paid to it. Older galvanised trays in particular have a working life shorter than the roof they sit in.
Leaf litter, twigs and grit collect in the channel and hold moisture against the metal permanently, which is exactly how rust starts. Then water finds the pinholes.
If your valley is packed with debris it is not draining properly either, which sends water sideways under the tiles instead of down the channel.
Old and rusting trays come out and new galvanised valley trays go in, sitting correctly under the tiles on both sides so water runs where it is meant to.
All the rubble goes with us rather than being left beside the house.
It means lifting the tiles down both sides of the valley, so it is worth doing properly rather than patching.
Water in a ceiling under a roof join usually means the valley, but not always. We confirm the source before quoting, because sealing the wrong thing fixes nothing.
Tiles down both sides of the valley are carefully lifted so the tray underneath can come out. This is the part that makes it a real job rather than a patch.
The failed valley tray comes out entirely. Patching over rust with sealant is a repair that lasts one winter, and we will not quote it.
A new galvanised valley tray goes in, set to drain properly along its full length.
The tiles come back down over the new tray, bedded and pointed where needed so the valley is sealed the way it should be.
All debris and the old tray leave the site with us.
Valley replacement is priced per job, because it depends on how many valleys, how long they are and how much tile work is involved in getting to them. It is often found and quoted alongside tile replacement or a full restoration. The onsite look is free and the quote is written before anyone starts.
Our guarantee covers defects in our materials and workmanship for 15 years from the day the job is finished. Plain terms, on our warranty page.
We work right across the Perth metro, north and south of the river. These suburbs have a page of their own: South Perth, Applecross, Ascot, Baldivis, Canning Vale, Joondalup, Midland, Wanneroo. If yours is not listed we almost certainly still get there, so ask and we will tell you straight away.
"Mati and Ryan did a fantastic job and I can't believe how wonderful my roof looks! Tiles replaced, ridge capping repaired, painted and sealed, plus extra jobs done at the last minute!"
"Awesome job. Great at communications and really looks after his clients. Rare to find people who will do their job and provide proper support these days. Killi is definitely one of them."
"Mati and his team did a great job on my roof. He was so busy but promised he would have it done by Christmas and he did. So happy with his work. Would highly recommend this company."
Rust or pinholes visible in the metal channel, debris packed into the valley, or a water stain in the ceiling directly under a roof join. From the ground you often cannot see any of it, which is why it gets found during another job.
You can put sealant over rust and it will hold for a winter. We do not quote it, because you will pay twice and the second time there will be more damage underneath.
The tray sits underneath the tiles on both sides, so the tiles have to come up to get it out and go back down afterwards, bedded and pointed where needed. That is the job, and anyone quoting it without that is not replacing the tray.
Yes. Valleys are one of the first things we look at on any roof, because a failed one undoes the rest of the work. If yours needs replacing we tell you as part of the restoration quote rather than after.
We come out, get on the roof and tell you whether it needs replacing or whether a restoration will do. If restoring will hold, that is what we will quote, and it is the cheaper job.
