Work to a Perlin roof without notifying us

[Andy62]

Warranty is a good idea. The roofer did say he would give me a 10 year warranty but didn't put it in writing. I will contact him and see what he says. Thank you for commenting.

Yes, we were not told about the work the builder just did it. I have double checked his invoices and there is nothing other than wood for new battens, felt, screws, cost of removal of all old tiles and ridge tiles, cost to buy new slate tiles, new ridges tiles. Leading and fitting costs for leadimg for around the chimneys and some windows and new fascia boards and guttering.

 

I cannot see all of the work he did. The photos of the work weren't taken by me they were taken by a friend who stayed at my house whilst the work was being done as we had to go away. it wasn't until I went in the loft and noticed loads of new wood that I did a double take. I can't see how I can be liable for anything  if I didn't even know the work had been done and I have the proof in the invoices.

 

Thanks again for commenting! 

Im not sure i understand this post.

 

You seem to be suggesting the work, the re-roofing that is, was done without your knowledge? That makes no sense. Surely you asked him to do some work on your roof? He didnt sneak up there and do it did he?

 

As far as BC goes, homeowner is responsible. The scope of work you posted is notifiable. That the builder added some extra timber is irrelevant as far this is concerned.

If you go for retrospective BC approval ('Regularisation', which used to cost 130 or 150% of the normal fee - can't remember which - as a sort of minor 'slap' for not doing it right 1st time) I think 2 Qs might be raised: 1. Is all the additional timberwork structurally sound? (You may need a structural engineer for that) 2. Did the roofer install any insulation at all? Since the  2010 revision of Part L, when insulation upon re-roofing 'became a thing', the 'norm' for areas over sloping ceilings (such as you have at the lower part of your roof) was (assuming 75mm rafters) 25mm vent path under slates/membrane and 50mm PIR friction-fitted between rafters. The gov't Best Practice Guidance (2021 or 2022, I think) now suggests a 50mm ventilation gap, which in the scenario above would give room only for 25mm PIR. As far as I can tell from your posts the roofer may have put in none at all, which is a pity, but on a practical level you might be able to 'offer' silly-deep (400, 500mm-ish) amounts of insulation on the flat ceilings to compensate.
