Damp Proofing

Damp & Extension Roof Retention Query

Anonymous user 23/02/2024 - 2.33 PM

Just a query, hoping for second professional opinion from a builder. Our Homebuyers report has been completed, we have not received the details as yet but spoke to Lender and they say £5k retention suggested by surveyor. Property is 1900 period. Spoke to Surveyor (full report to follow in post shortly) Retention is for rising damp in dinning area and also damp in upstairs back bedroom - part of extension. Also 2 storey extension has roof sagging due to concrete tiles and not enough support on this part of roof. (main roof is fine and no mention of any other damp elsewhere). Surveyor says scaffolding maybe required for roof and repairing cracked render ( i think near roof). So we would have the potential cost of scaffolding, new roof tiles on extension, support beams for extension roof (stop sagging), damp course i assume just for affected areas? plastering, parts and labour. Our Surveyour estimated £4k for this. Extension 25sq metres or 3.5 metres by 7 metres Firstly is this price realistic? Second we have already told the estate agent to ask the vendor to sort this before we complete, so they absorb the costs, it's a buyers market right? Third anything anyhing we should be aware of know/do?

Are you a tradesperson and able to answer this question?

I think you should double that price, 4k wouldnt cover that amount of work, unless your doing it yourself.

agree with bjd building and roofing, your surveyors estimate is well short for the amount of work involved. scaffolding will definetly be required, no roofer would re-move a roof and replace it of a ladder would also be looking at the main roof if this has been re-done in concrete tiles could be a weight issue here as well. damp issue in bedroom extension could be from the roof while it may be a buyers market the cost to repair the above may put the seller of selling you the property, depends how keen you are on buying the house and how desperate they are on selling

4K is definitely light for that work. Also, it you strip more than 25% of the roof coverings (which you will to put in new structural supports) you are obliged undere the Building Regulations to bring the insulation levels of the roof up to current standards. And you should submit your roof design to Building Control for approval as its an 'element of structure' and needs to be approved.
