I'm in the process of having a Xtrordinair 44 elite installed and am fixing to frame out the chase for the chimney this weekend. Had a reputable roofing company out to give me a bid on installing the flashing and sealing things up around the chimney, the bid came in at $585. Sounds pretty high to me, our house in single story and the roof pitch is 5:12. Materials for this have got to be minimal?! What do ya'll think, am I just being cheap?
