Hi, my son recently bought a 3 bedroom semi detached house which is only about 3 years old. The surveyor noticed a small amount of condensation in the loft and suggested the loft floor boards are removed ( only about one third of the loft is boarded )
Recently my son noticed the condensation is a lot worse with moisture dripping from the roof felt material.
He contacted the NHBC but they have been less than helpful, just sending him a leaflet about condensation. he is now contacting them again to get some practical help in sorting this out.
could someone on here please help with the following?;
1) Can boarding out a loft cause condensation?
2) Can a loft have too much ventilation. ( daylight can be seen along almost the whole length of one of the eaves.
3) Should bathroom extractor fans be vented directly outside, one of my sons 2 bathrooms is vented through the loft although my son is not using this fan now and the vent is closed when not in use.
PS There is a good amount of loft insulation, a depth of about I foot.
Thank you for any advice you may be able to offer.
John
