Unfortunate google doesn't allow negative rating. Zico replaced our roof, thereafter I see nails upto 1inch inside the house. There are hundreds of nails exposed upto 1in just in attic. One now has to enter the attic with helmet. Brought this to Zico's attention, but he won't respond. Worst. I want this fixed, before there is any head injury. If someone can rec me authority that can handle this, pls lmk.
