A good answer gets specific: soft sheathing near a vent, a hidden second layer, chimney flashing that was caulked instead of stepped. How are you treating hip and ridge lengths and waste on a 26 square hip roof? A good answer names a foreman and says plainly whether the labor is in-house or subcontracted. A good answer gives a per-sheet price and a call-before-we-proceed rule, agreed in writing beforehand. A scan can tell you a roof is 26 squares and that one plane took the worst of the storm.
