Hi All,
new here so please bear with me. I have recently replaced the flat roof on my brick built shed and am thinking I am wanting to insulate the roof as I am getting condensation on the underside of the roof boards. I have some left over loft insulation, enough to do the job, so was thinking of putting that between the joists (4" x 2") then boarding the underside. I guess my questions are...
Will the loft insulation be ok for the job?
Do I need to put a waterproof membrane up before boarding in?
Do I need to allow any kind of ventilation within the roof?
Sorry if these questions have been asked before but would really like help written in one place so I can get my head around it.
Many thanks in advance.
