Hi, thanks for putting up all the photos of your build it’s very helpful, I have done a shed dormer on my on my timber frame house I am building similar to yours, the question I have is about how the roofers went about the ridge on the dormer where there are different pitches on either side. Did they use a dry ridge system? (Is so do you know which one?) or did they mortar bed them on that part? (If so did they add any additional ventilation there?) many thanks for your time and I hope all is well with you and your home ?
