Any ex builders on here need advice on some roof joist is it to code

[round2it]

 

 

I am having a conservatory built and dont know if the builder has put the roof on correctly

 

the joists look too thin at one end.

 

 

what do you think

[Andrew_C]

:jaw:I think that unless there is NO chance of snow load, and you are having a paper weight roof covering, that is a bodge.

[Seb1780]

Shocking!

[round2it]

yes i thought that,it is a plastic tile roof not much weight he is about 16stone and he stood on the top of the roof

[round2it]

looks like im going to hold back on the final payment now and get a new builder in to redo the roof

[Achandler]

He bought the joists for a roof with an overhang and then you don't have one, hence the taper issue. But yeah, I wouldn't be happy with that

[round2it]

any advice on what to do next,i would have said that both ends should be on hangers

[Achandler]

Well cut joists into hangers against the end board would mean a lower ceiling as well, the plasterboard would almost block the top of what I presume is doors at the end. You you need to lift the whole end of the conservatory roof to put support underneath, which will effect the angle, which might affect where it is hung against the property. The tapered end is also most exposed to any elements and most likely in the longer term to rot.

 

Are you expecting a flat roof on the insider or angled, if flat then there may be a way to put a support across before the taper to help take the weight, it would need to be where the windows meet though to help transfer it to the floor, you don't want to end up boxing a UPVC windows frame.

 

I'm genuinely not sure what your best option would be. I'm not an ex builder, but I've had a fair amount of experience building porches, garages, side extensions with flat roofs and angled ones.

Either replace all those joists to reach the bearer, and use hangers, or possibly (many years since I dealt with building regs) put a couple of side - side joist in to carry the ends.

 

ETA -

 

It might be worth contacting your local building control. It may be that your conservatory is "outside of the scope" or it maybe that you don't want them involved because it ISN'T outside the scope, and you haven't applied. However, you might find they have a lot of clout with a builder who has multiple jobs on their patch that they start taking a pointed interest in.

Screw some angle brackets into each joist.

 

Do you have a buildings inspector from the council for this work? They are usually great for this sort of info.

at the end of the day its the builders issue he is not getting paid until the job is put right i just wanted other peoples opinion,my thoughts are i would put an extra beam across from window to window to transfer the weight to the footings. but good shout about the angles. I might pay for the building inspector to come and look as this looks like a bodge it and leg it job.

 

thank god i paid in stages everything else is fine its just looks like not enough support

[round2it]

it is outside of scope 3mtrs by 3mtrs 50% glass

 

not more that 3 metres high so boundary issues are negated

The extra beam might be a better solution, and would be less noticeable. I can see why they did it - so the ceiling remains flat. I don't think it's a massive problem to put right - if its <3M it's not load bearing and the rafters at the end look well secure, so don't lose sleep over it.

i was away when doing it so did not get chance to question,he has put internal roof in so he might have to redo it but it is upv panels so should not be expensive to fix

[Ditto]

Something very wrong there! The left and right ones look fine, but it's almost if they cut 7 by mistake and fitted them anyway. I'd go with the earlier advice - get building control around and ask them to sign the job off before paying anything. I'd be questioning the wood quality too. Bottom line is regardless of the need to get planning or not, there remains a requirement to meet building regulations.

[round2it]

so the builder will now install an extra beam across the entire roof to ensure some extra support, this will then be boxed in so hopefully everything should be fine.

 

im glad it was not just me thinking its not right

 

thanks for the comments

I still would agree with other edugeekers recommending getting a third party assessment of the finished product from building control before paying the final payment.

[round2it]

Already on that

[richardbarnett]

If the joists end there, whats on the outside to attach guttering and facia to?

I would have thought they needed to be longer and attached with twist straps maybe to avoid the low ceiling.

[round2it]

had building control look at it now after the extra joist was put in place and they are happy with the build without the extra joist the building was not to code so im glad i got them involved

[PotNoodleTech]

I aint no builder but to me that looks like the whole centre of your roof is being held up by about 5mm thick wood.

 

It's a NOPE from me!!!
