Ceiling Deflection

[Nickfromwales]

Ah, pyramid roof no gable end wall....? First pic I saw up top, I thought was a gable.

 

Still doable with some steelwork or a bloody good chippy, assuming a dual cylinder platform could be formed to sit on the masonry wall. Depends on how badly you want the accumulator, as the minimum I'd recommend without pumps is a 300L.

 

To be honest, these are the kinds of jobs I used to love doing, especially when someone told me it can't be done .

Gasp. 

They built that brick to support the roof?

Purlin, or purlin struts have to sit on something that connects the roof to the founds? This is normal.

I mean the single brick on edge and simple (minimal)? contact of purlin to brick. 

Any tiny movement will rock that brick.

 

All I'd suggest is 2 bricks instead of one, laid flat, and a timber sole plate.

Being a pyramid roof, linear movement is unlikely. Most purlin struts I've seen have been a max 100mm wide timber, sat on a single skin masonry wall. Next to zero dynamic movement here other than wind-shear, so doubt it's an issue.

Yes, I'd improve that with a cut timber, birds-mouthed to accept the purlin so the flat side of the timber rested on the final laid course of brickwork, but I expect this has been there for multiples of decades without a single issue.....

OK I have misunderstood and thought it was new.

Need some advise regarding the following please… 

It would be a good idea to get an SE in to have a look at this. One thing that you need to look out for is when you muck about with the roof you can change the load paths on the floors below / any old beams and so on. This can become an issue. 

 

As a domestic Client you have a good bit of protection under the consumer protection act, the building regulations, CDM regulations and the HSE act 1974. 

 

Write to Oso and say that in the interests of fairness it would be appropriate to get a independent opinion. Say you are seriously concerned about the safety of the structure and give them 48 hours to respond. Point out that you have observed excessive deflections. Do this right away, don't delay! I agree with the other posters.. It does not look rosy as things stand and seeing the standard of workmanship gives me concern in terms of safety. 

 

You need to take the long view. At some point you will want to sell the house so best to get all your ducks in a row.

OSO should concede and take full ownership of this (hopefully isolated) feck up. Would be good if they do this with the least amount of resistance.

 

There's zero argument of like for like, or "there was one there before, we just replaced it" as the cylinder is larger than the original therefore it is a new and unique undertaking.
