Alpine came in among the lowest quotes for stripping shingles, roofing and flashing. They made errors here are there but they took full responsibility and carried out callbacks in a timely manner. I would recommend keeping an eye on the guys who do any flashings. Our crew seemed inexperienced given that they banged up the flashings something awful. Another crew was called in to repair the first job and the did okay. Chimney flashings took three or four callbacks before the job was finished to our satisfaction.
