They did a good job yet feel they were in cohoots with covering for the dishonest main contractor (who went from great to horrible in one day) and have to wonder why they have to refer so many folks to the chimney experts; are they sharing referral fees or something? I would not recommend them, though might mention they have been around long enough that it might be worth a call. Most roofers don't get referalls; they work like they know they (hopefully)won't be needed again for 30 yrs.
