Big job? roof bracing framework and gable wall restraint


I'm looking to buy a new house (first time buyer) and the survey has come up stating the following:

"There is insufficient bracing to the roof framework which could allow movement of the trusses. Also, the flank gable walls has not been properly restrained and is at risk of movement. Correct bracing and restraint should now be provided by a competent contractor in accordance with current Building Regulations.
The main roof void does not appear to be sufficiently ventilated. Fixed air vents should now be installed to prevent moisture condensing on the timbers. In the long term, it is possible that timber decay could develop if correct ventilation is not installed. The vents should not be obstructed by insulation."

Now to me, this sounds like quite a big job but then agar I'm not expert, hence the question here :)

Does anyone know if this is a large job? It's a 3 bed, detached house.
Is it reasonable for me to ask a couple of builders to pop around to the house to take a look to assess the extent of the work?

Any advice would be appreciated.

Hi there, just a quick answer to your question, this is not a major job but could lead to major problems if not dealt with correctly. The roof bracing should be braced with 4x1 timbers running from gable to gable (if timbers do not reach the span of roof additional timbers must span at least 3 trusses roughly 1800mm) with no gaps and nailed twice onto every roof truss, the braces should be spaced out no less more than two metres apart going along the ceiling chord of the truss and up the slope of the truss, also if there is no restraint straps fixed onto truss going into the cavity they will also need completing.
