Insulating Flat Roof Space

With flat roof insulation a vapor barrier should sit between the joists and ceiling panels and the insulation on top.

Insulating flat roof space.

Insulating a roof will certainly increase the snow load if you are increasing the insulation in a heated space. While insulation for a flat roof is expensive and can account for as much as 25 of the total installation cost there are a number of important benefits to having it in place. Insulating a roof is perhaps the easiest of all the energy saving home improvements. Bypasses are anywhere that there is a break in the insulation.

This method involves leaving a ventilation space above the insulation. When the insulation is installed properly there will be plenty of ventilation for a residential structure. It s also within the capability of most diyers although not the most pleasant of tasks. Use rigid foam insulation panels on your flat roof before applying the final roof covering or inside the house before adding sheetrock or paneling.

Mineral wool rolls are ubiquitous and cheap meaning a whole roof on a standard home could be insulated to the recommended 270mm with a spend of little more than 200. The space is located beneath the roof sheathing and above the ceiling of the living space. But going from an unheated uninsulated space to a heated insulated space might not increase the snow load much. Rigid foam panels are available in thickness.

This could be a hole crack or other kind of unprotected space that the insulation does not cover such as around a light fixture. You are increasing the dead load of materials though. Reduce extreme temperature fluctuations inside your home.
