Lean to with corrugated plastic roof

[sq8r]

Hello,

I am planning to build a small lean to (put a roof on) between our house and the fence next to our house. I have a reasonable idea on how to do this but would really appreciate some advice on specifics.


This is the area to be covered:

It's about 170cm by 300cm.

I am planning to attach a piece of wood to the fascia on the house to support the end of the plastic. Use 2"x4" 'rafters' but how do I easily attach these to the house?

On the fence side, the roof will need to be significantly higher than the top of the fence. I think I need to extend the fence posts with something. Any tips on how to make this look neat?

I don't want the guttering I am planning to put on to overhang the neighbours' property if I can help it. So the uprights will need to be this side of the fence with the end of the roof and guttering hanging over the end.

Any thoughts, recommendations?

Thanks in advance, Dan

With regards to the fence side it's not a good idea to attach the roof to the fence or extend the fence posts. It's better to remove some blocks, concrete in some nice freestanding uprights about 7 inches in from the boundary so that when your wallplate is on the gutter will be on the boundary.

If it was my house i'd do it in poly using self supported bars, will look nice and smart, that corrugated stuff is shyte obviously poly and bars does add ££'s but will last forever.

You could use truss clips to attach to the wall.

Thanks for the advice. Not sure about putting new posts in as I am trying to maximise the usable area underneath the roof. self supported option is too pricey for me TBH. Still, food for thought. Thanks.

Thanks. That's what I needed, just wasn't sure of the name of them.

Hello again, right I think I've ballsed up here. I've bought one of these:

http://www.livsupplies.co.uk/product_desc3.php?id=318

Under the impression that it would be (a) easy to put up and (b) was actually self supporting. Now I've unpacked it I can see that it is not easy to erect and I can't see how it could be "self-supporting".

Could anyone offer me some advice as to how I could progress on this? If it will actually support itself with no fence posts or the like then I'll no doubt need someone to come and fit it for me. If not, then I've £600 worth of roofing sitting here gathering dust. Hmmph.

Any advice/help?

thanks, Dan

If you look on the fitting instructions on the link you supplied,
you will see the gutter side sits on a row of windows.
By self supporting I beleive it means no additional raftering, trusses, purlins etc.

If you just attached that to the wall alone it would rip the bricks out, if not straight away then definately as soon as there was a heavy wind or some snow...

If you were desperate for a no support on one side then I would have gone for a cantilevered timber construction,
Something like this on a less grand scale, note the diagonals:

although supporting either side would always be preferential.

Here's a cantilevered carport I found after a quick Google.

If you don't want to support on the fence side, distance selling regulation may be your friend...

Self supporting means the bars dont bend under weight as opposed to thin bars that need to be supported by timber.

The only way you can make this work is by putting up posts along the fence side and making an eaves beam for the bars to fix to.

You should have called in the professionals **COUGH**

Thanks, I feel quite stupid now TBH. Can you clarify what you mean by distant selling regulation?

Yes, you're right I should have just got someone in to do the job for me.

Oh well, you live and learn...... and loose money.

Everyone makes mistakes, it's easily done,
£600 is a whopper though...

If you bought an item without seeing it first (i.e. You ordered off the web) you have the right to return it within 14days.

Alternatively workout a minimally intrusive way of making support on the fence side, as roofline said, posts and a beam.

DSR is 7 days and OP may have to pay return shipping.

ETA:

T&C from OP's supplier - clause 10.

just put some 75mm posts in!

you wont maximise your space by pulling your neighbours fence over...

seriously consider if you can afford to lose 75mm width and make life easy for yourself with £50 worth of timber..

What's £50 now?

Are you suggesting that I rest the huge roof I bought on some new posts? Or ditch the roof and build something more, erm, modest?

[munchingB]

yes something more modest-like your self levitating roof...

use the roof you have if you can enchant it to be conventionally tied in place and give up its career as magicians assistant..

couple of posts 75x75 or 100x100mm, a timber to join between them. timbers from the posts to the wall if need be. something on the wall-depending on how its fitted. concrete for the posts. joist hangers if your joinery skills are poop.

not too far off £50.

does not have to look at all shabby-but that depends on how you want to finish it..?

if you really insist on having it look more modest just do some bird poops on the glass and it will humble it down it no time.
