    As part of our new build we're looking at rainwater recycling.

    As we live surrounded by trees what is the best way of stopping leaf litter getting into the gutters and ultimately into the rainwater recycling tank?

    or my DIY solution :smile:
  1.  
    We used Coburg gutter grid 10 years ago was the only option in terms of off the shelf product then. We used to have trees above the entire back of house and the leaves would block every down pipe. Fits really nicely to Lindab guttering, they still seem to be on the web. Now there is a lot more choice, even screwfix have two products:
    http://www.screwfix.com/p/gutter-clear-mesh-5m-x-110mm/88873

    My concern would be that your system would allow leaves straight into rainwater tank though, our system uses a very fine mesh filter which draws the clean water through leaving any debris to fall into the soak away. I would imagine a direct flow into the tank would result in excessive rubbish in the tank.

    Our house replaced the mobile home we lived in, which had no guttering!. We're well and truly surrounded by oak and birch trees and I hadn't quite realised what a pain it would be to clear our very nice Lindab guttering every few months (weeks in the autumn). A few weeks ago I started looking into the multiude of different gutter solutions available on the market. To be quite honest, it would appear that none of them work properly. I do love a challenge.....

    Spent some considerable time working my way through battery powered auger feed system, inflatable air tube, inner tip out liner etc. etc. but none of them seemed a realistic solution, especially given that the tiny seeds of the birch tree turn into porridge when wet. I was also working on the perfect solution to stopping midges getting into the house and had a bit of spare grey fibreglass fly screen lying around, mmmm...

    The trouble with mesh over the gutters is that it soon clogs up and you then spend as much time cleaning the mesh as you would have done cleaning the gutters, but, if it were fixed on a slope? I taped a bit in place , threw some handy gutter debris on it and watched the majority roll off (got a good slope on the roof). Got the hose out and gave it a good dousing, water went into gutter, but not the carp. Technically Ok, but what did it look like?.

    We've got a slate roof and amazingly, the mesh was almost unnoticeable, great!

    But how to fix?

    I tried a bit of superglue...it worked! (£3.00 for 3 grams!) Loctite, far too expensive! Found toolstation selling it for 50g for £2.99. Did a 2m test piece on Friday, seemed to work fine.

    The mesh (400mm wide roll), is rolled along the roof, taped into position so that it covers the bottom line of tiles and drapes over the guttering , I then cut the mesh along the bottom edge of the next tile up. Then it's out with the superglue (did 13 metre gutter round the back on Sunday). Then I pull it taut over the rolled front edge of the Lindab and glue it again. Simples and still looks pretty good.

    Had a big downpour yesterday, but worked fine.

    Downside. Some birch seed just sits on the mesh, but I don't think it will accumulate. When the mesh dries out, they loosen up and blow off. Might not be frost proof or snow proof, will report back post winter. Might encourage growth of lichen (don't know). Water tends to bead on mesh, so more noticeable when wet..solution, don't stand in the rain looking at the appearance of the mesh!. A little bit of water manages to bead and roll over the mesh .03% ish, but, hey, the ground is wet below anyway.

    I'll post some pics if I can.

    Now we're debating whether it's more useful to fix mesh to the outer edge of the gutter,
    at the same angle as the roof (so there's some movement in it and it's not visible) ... or to try out the linear PV idea (DIY panels of dimensions approx 100mm by 6000mm)

    Is it still winter where you are?!

    Whole build looks good to me! ... how easy do you reckon cleaning out is going to be if ever needed?
    Think there's potential here for an "S" shaped "product" that clips to the outer gutter edge only and sits at as angle.

    The cocky answer is, " won't need to clean it out". Since the weekend the sparrows have brought in bits of grass on a daily basis, I've started putting mesh on the open ends now!

    The S shape idea....The mesh only works on a single flat plane at a steep angle. Anything else is going to collect debris, methinks. Stopping debris build up where the S shape joins the roof is also going to be tricky, superglue isn't very thick.

    I oversized the gutter to our dormer, at 125 mm instead of 100 mm, in the hope that this would help. Windy up there too so I imagine it should be okay.

    I can't imagine that hedgehog thing is any good. Surely it just restricts the flushing out of the gutter and encourages dust and dirt to collect?

    BTW dickster, nice looking house. I'm not a fan of bricks, myself, but they fit in very well there. Self build? Have you done any write up of it here or anywhere?

    Like others, our house is surrounded by various trees and beech hedging, resulting in significant fall of leaves and debris in Autumn and Winter. We fitted gutter hedgehogs, which are in effect large bottle type brushes which sit neatly inside the gutter half round. Perhaps not the most elegant solution as you see the top half protruding out the gutter. however, they work fantastically, and keep the gutters clear / water flowing. Every Spring I spend an hour removing the hedgehogs, give them a shake and refit them. The only debris in the bottom of the gutter that remains is the fine bits of slate from when the roof slates were actually fitted. I dare say a power-wash of the gutters proper every 10 years will suffice.

    Roof hedgehog now seem to be retailing at around £13 for 4 metres (less than when I installed). An average house with 30 metres of gutter, you are looking at just over £100. Beats having to go out on a rainy day and unblock gutters by hand. Easy to fit as you just roll out into the gutter. I tuck the ends of each brush under a slate to hold in place although equally one could use a cable tie which is easy enough to cut during the annual shake off.

    Miike and Ed, thanks for the compliments. Not an actual self build, but a "client (us) heavily involved in all aspects of design, materials, quality etc." type job. I suppose we managed with the builder and architect to do a good job and got our hands dirty on many an occasion.

    Very expensive, but small enough not to have to compromise too much.

    Haven't done a write up or blog, I suppose too busy, but a piled foundation, concrete ring beam, most floor, walls and roof made of hardboard skinned engineered timber 300mm beams packed with insulation, mainly blown paper.

    The cladding is sweet chestnut (now 2 years old), roof welsh slate. Thermally up to expectation, 5 Kw wood burner only heat source used. LPG combi for hot water.

    Mike, S shape looks good, unfortunately our tiles dip well into the gutter and so wouldn't work.

    I'm not quite sure why the manufacturers of guttering don't liase with roofing material people to design and build both to solve this really annoying problem, perhaps not enough demand?

    Finished all the guttering this weekend, fingers crossed that I get a few years out of it before the problems with this approach become apparent.

    @Dickster. Not sure if you are still avtive on here, but I'm liking your mesh over gutter approach. I'm looking to do the same with my steel guttering as also surrounded by trees and don't fancy cleaning the gutters out 6m up each year.

    How has the mesh fared over the years? Did the superglue hold where you glued it down along the edge of the gutter?

    TIA!

    Hi Kentishgreen, I'm still about, but enjoying other projects in my "spare" time.

    The fibreglass mesh is still going strong, it's faded a bit from UV, but not really a problem. I thought lichen growth would stimey it, but it doesn't seem to affect it. So all in all, fantastic.

    I do, of course, still have to clear the leaves on the ground!!!!.

    If you are going to attempt it, here's some tips. I foamy pan scourer cleaned with water all surfaces to be glued. Cut mesh over size and roll out and clothes peg/ gaffa tape it into position.

    On the top edge, tack it in place by dobbing a spot of superglue THROUGH the mesh and hold in place, then move on maybe a metre, another dob etc.

    Ditto bottom edge. Then go along with glue all the way, top and bottom. Then trim with v sharp blade.

    Do a test piece first, then chuck some shitty leaves etc over it, then hose down. If it works, crack on. Not sure if UK too cold to do it now, maybe wait for spring?

    Remember that I was very lucky with angles of roof/gutter position. When it rains, the mesh sags very slightly and is drawn down and stuck by the water to the tile down maybe the first 75mm of the tile. The rain is drawn through the mesh even in the heaviest downpour.

    There has been a build up of dust/ gunge in the gutter, but maybe 6mm over 4 years.

    Let me know how you get on!

    Thanks for the update! Still fairly mild here in SE England so I think superglue would still be okay. I also want to get rid of the scaffolding asap so must get it done now and not on a ladder 5m up in the spring!!

    Not gone for Lindab, but Roofart and I may be able to clip the mesh into place on the gutter side rather than glue (and roof side, I will have to undo some of the coper rivets, lift slates and the slide mesh under (replacing rivets). Pitch is 33deg.

    Hoping mine is going to look as yours - and as effective!

    One last question - what sized/guage steel mesh did you use?

    Not steel but fibreglass, as far as I can see. (Dickster's first post 6th Aug 2013 above).
