We took our bathroom ceiling down yesterday to discover that they never reinforced the original rafters (4x1) when changing the roof tiles from slate to concrete 
It's a single pitch roof about 4 - 5 metres long. The ceiling joists attach onto the rafters at one end, so I would imagine the ceiling is adding weight to the rafters also.
Would really appreciate it if any builders or roofers could give me an idea as to how I can fix this? |

Waiting for Fab builders to come along to advise . Some will even do the work in kind 
Do you not have anyone in your area to quote ? |

Posted the job on mybuilder about six hours ago and no interest - it's probably the job from hell!
From what I gather builders are overloaded with work at the moment so would consider doing it myself if I know what to do. |

"Builders have mortgages and mouths to feed too "
I have a mortgage and mouths to feed, but I do some private jobs outside of work and sometimes get paid in food
P.s I'm not a builder. |

"Are there any visible signs that your rafters are bowing?
Yes, a couple quite severely!
Then I would suggest that you contact the original contractor who carried out the work "
No idea who that would be, it was probably done many years ago before we bought the property |

Thats going to be a major job, sorry to break it to you. Your looking at possibly replacing or at a minimum, strengthening all your joists and rafters. Most builders will be reluctant to reinforce another fellas bad work and will probably recommend a new roof and ceiling. However, it might work out better in the long run to do a proper job than trying to patch up and work around future problems. |

"First port of call is your insurance company.
Take their advice and go from there.

I hadn't thought of that but it looks like I can fix it for £262
I doubt they would accept a claim due to gross negligence which is what the original job was. |

Indeed but not in your time line you say so if it’s dangerous the cheapest option for them could be to repair for you.

It is bad and needs fixing asap - I'll be on it Monday morning |

How long ago was it done, and fdo you know what tiles are on there, how old is the house..?
Old slate was thin but heavy, big 49 tiles are heavy but not many per Sqm, plain concrete only light and 60 per Sqm, its all about spreading the weight, roofs naturally settle any way, prob no more than some support struts from the purlin required of anything, and yes before the haters shout Loft conversions are a speciality.. |

There is no purlin - and the ceiling joists hang off the rafters at one end creating an angled ceiling at the eves - so will put a RSJ through and then strut off of that - solution thanks to the advice from a couple of builders. |

Rsj is a bit overkill a 7x2 c24 is more than adequate and a lot easier to install |

You think that would be enough over a 4 metre span?"
you can get laminated joists which are cheaper and easier to install instead of steel tbh you need a professional to look at it’s not easy to give advice without seeing the job |

Didn't you get a survey before you bought it? Did the surveyor not pick up on it? |

You think that would be enough over a 4 metre span, unsupported? The rafters wont support because they're actually hanging off the rafters themselves at one end. |

We didn't use a surveyor and it's a complete renovation project, so not unexpected. |

That's what I'll do then - will be a lot better than dragging 80kg of steel up there - thanks |

Hi just checked the tables set out by building control you would actually need an 8x2 c24 over a 4.5m span or 6x2 doubled up and bolted together . |

We've used mybuilder 4 times previously - have always been really happy with the responses and the jobs they have done - if you posted recently I think the builders are taking on the bigger jobs, and can't say I blame them |

I wouldnt breath with a sigh of relief yet, As youve got fun coming for what you intend to do.
first of all you need 2 holes chiseled out one may have to go through to the outside
then you need to brace your roof while you install the new beam in place
lock it in place while you unbrace and nail each rafter to the beam from underneath.
then fit the last beam in and coach bolt all the way along
so your in for some fun and half |

Was going to lay the double beam
horizontally along the top of the ceiling joists, on a joist hanger one end and on top of the wall the other,
as the wall stops just above ceiling height. Then use struts from the beam to the rafters? |

too much roof weight for joist hangers
wall to wall joist then struts on top of beam to rafter but your better off fixing a 4x2 to rafter easier to screw or nail the 4x2 to rafter and then fasten in struts under the rafter from beam to 4x2 on rafter
this will support it better when you remove the support plank and supports for the roof |
