Many homes may be exposed to roof maintenance problems, such as torn or punctured damp-proofing. Any part of the roof or loft, such as tie beams, ought to be checked. The RICS surveyors could suggest that some of the faults must be dealt with immediately. Maintenance need not always be costly, but they should be budgeted for carefully. A Building Survey (RICS Level 3) prior to exchange is highly recommended, so that you fully understand what expenses you will be facing.
