Submit plansWe have just had a survey on a house we intend to buy. One of the things the survey showed was that there is extensive damage to the sarking felt beneath the roof tiles. Can you tell me if this is serious and how much would it cost to put right?
Sarking or roofing felt is intended to act a an extra protective layer in case any rainwater seeps through the slates or tiles. It can only be put right by removing the tiles, laying new felt and relaying the tiles – it will probably need new battens as well. This work would probably cost between £12 and £15 per m² to put right, so you should reduce your offer by the appropriate sum or ask the vendor to carry out the work before the sale. It’s worth showing the house to a couple of roofing contractors for a more accurate fi ure.
