Hello,
we are currently building a single-family house with a general contractor, with a garage as an extension. The roofer was here recently and installed the garage roof. Since we don't have much experience, we would like to ask you about the execution. The garage roof is supposed to be a flat roof with a parapet on the front side (made of roof tiles). I have attached the ground plan of the ground floor and a section view of the garage. Now the roofer placed the first large beam directly against the house wall without any sealing or insulating layer between the house and the beam. In some places, there is even a large gap of 1-2 cm visible. The extension including the garage is insulated with wool at the height of the ring beam, as can be seen in the section. This leaves an air space between the wool and the boards that were nailed on top of the beams. We are now concerned that due to temperature changes (heating up during the day / cooling at night) condensation will form, especially standing in the gap between the house wall and the beam, leading to mold growth. What do you think about this execution?
Please contact us for further explanations or pictures.
Thank you very much for your answers.
