Flat roof condensation risk analysis.
For a flat roof construction be it a cold roof a warm roof or a warm inverted roof the calculation method for year round condensation risk set out in bs en iso 13788 known as the glaser method is almost always sufficient.
As long as the roof accords with good practice then a more complex calculation method should not be necessary.
This is something we do for all our new roofs as well as part of our design service.
In the above example of a condensation risk analysis the top line t represents temperature and the bottom line d represents the material s predicted dewpoint temperature which varies with the amount of moisture in the air in high humidity conditions a material s dewpoint temperature is increased.
Flat roof refurbishment best.
A condensation risk analysis is unable to allow for varying standards of workmanship but a high.
The analysis will determine the dew point and you can check where the condensation is happening in the report.
Flat roofs are among the simplest construction elements that can feature in a building.
