What to do if my survey says the property has problems with the roof
A roof is generally expected to last about 20 years. If the roof is ten years old and the surveyor has said you should expect to replace it in 10 years time, this is normal and not a place where you can expect to renegotiate the sale price with the vendor.
This is really important because understanding the difference between a "problem" and an observation about the general (and normal) state of something is critical to avoiding unnecessary conflicts, especially in a market where vendors know there are plenty of other buyers out there.
If the surveyor believes there is an actual problem with the roof they will put a retention on the valuation - basically saying they agree the property is worth what you have offered but not until the roof is checked out by a specialist.
That said its always nice to know what work might be just around the corner so getting a qualified roofer to come and take a look is no harm - the estate agent can usually recommend a few.
In fact when I am involved in the purchase of a period house I always get a roofer in anyway. I expect there will be works now and going forward, that is the nature of older properties, but getting the heads up as to what they are helps me budget.
