Can I jack this sag out?

[tombodge]

Do you think it would be possible to make a good improvement to this sag?


Buy using acro props/ car jacks onto the ridge line.


I don't want to damage the roof in the process

Why?

No.

Wouldn't touch it. It's been built like that, all the interlocking roof tiles and ridge tiles are together. Is it water tight?

I'd be more worried about the chimney mate.

Its probably a classic example of concrete tile being substituted for slate with all the extra weight of the tile. Unless you have removed some collar ties, struts or "posts" from the roof construction?

What is going on below where all new loft joists can be seen with a further arrangement above? Have you lowered the first floor ceiling?

If any signs of roof spread can be seen then clip (see Simpsons catalog) the rafters to the purlins.

Those verges look a bit naughty, I would get those done asap.

the hole thing is a bit naught and bodged together.


The roof has spread and pushed 2 rows of bricks out along the back of the house.

Im trying to weight up between have the hole thing repaired / bodged up. I can find around 8 different things that need doing to it including the chimney.

Or get it replaced with slate with the sagging been taken out at the same time.


Im not keen on repairing it and having a mass of ties and surports inside the roof for the next buyer to complane about. Plus with all the other repairs I can't see it been much cheaper for the repair

On the inside or outside? I was going to rebuild it but only from the roof up

Perhaps,you will go up and take pics of the pushed out brickwork at the rear elevation - do it from outside and inside. Then, maybe, do the same at the front elevation.

Has the rear elevation wall remained plumb (excepting the top courses)? Just how loose are the top bricks?

Have any doors or windows become sticky to open?

Has any skirting board lifted, even just a little, from the flooring?

With respect, Stop all your DIY attempts to correct the sagging - you could cause more damage.

Have you noticed any cracking on the inside corners where interior walls meet the outside walls?

Can you list the eight faults that you've noticed in the roof/loft area?

 

[ree]

Staring at the pics:

the rafters on the left seem to be more distressed than the rafters on the right.

Is the purlin on the left firmly fixed into the party walls brickwork, or does it sit outside the wall, and is it propped near the centre of its span?

Something very odd about all this - have any walls or partitions been removed from any lower floor? Has the chimney breast been removed from any lower floor?

The loft joists are at the wrong height - how are the rafter feet tied into the wall plates and joists?

From what can be seen and assumed i would say that your house appears to be in a possibly dangerous condition, and only by removing and re-building the roof will you correct things. Further information might change my view but for now, thats how i see it.

In the first picture it looks as though the first floor ceiling has been removed and joists replaced with new timber. Is this correct? Were these tied back in to the wallplates and rafter feet. How was it done - one by one, or all at once?

 

[skhudy]

I'm a DIYer but looking at the pics this is my guess

I may be wrong but has a supporting wall down the middle of the house been removed, along with that the ceiling on the 1st floor has been rebuilt / replaced, and with that the supporting struts etc which make the roof structure have been removed.

Looking at the pictures it looks like the roof is spreading and pushing out all the brickwork. The whole roof needs to be replaced / looked at.. urgently.. by someone qualified

n.b I just saw your earlier posts "about to order purchase all the things to remove my load bearing walls" and re-roofing DIY I think...

 

[tombodge]

No walls have been removed and no stuts have been removed. Although walls are been removed

All the houses are the same and they are all constructed in the same way.

You are all correct the ceiling joists don't attach to the joists. This i how it was built in the first place and it can't be built any differently. A very poor design and alot of these houses have sags or new roofs

I have replaced the ceiling.

The rest of the house is fine. There no subsiding and no cracks ect. The walls are true its only the top 2 rows of bricks that have moved.


Im aware that it needs sorting asap.

What ever I end up doing with it I want the end result to be a roof that looks correct and unrepaired from the inside and out.

You've given me the info i was looking for.

Without ripping it all off and going back to the original slate roof (with the repairs) It would end up still with the sagging roof and with a network of reinforcements inside the loft to stop the problem getting worse.


Which I don't want. So i guess it needs to be replaced

The people who have put those concrete roof tiles on your roof have double the original slate load.
