Will a roof specialist get up a ladder as part of a roof survey?
Yes! They need to look at the roof and structures up close to do a proper inspection.
What’s the cost of a roof survey?
The price of a roof survey depends on how big a property’s roof is. Prices start from around £150 for a terraced house, rising to around £300 and upwards for a large detached house. As roof repairs generally cost around £200 - £300 to fix, a survey is almost an investment because of money you’ll probably save in repairs in the future.
