The question: as an inspector who is looking at a new house, you encounter a roof which is installed in the following order: sheathing, tar paper, drip edge, shingles. (The correct order is sheathing, drip edge, tar paper, shingles). What do you say?
The real answer: why did the professional roofer not install ice and water barrier? And if a professional roofer wouldn't use ice and water barrier, then why would you want a professional roofer doing your roof inspections?
Anyone?
