We are having a new roof installed on the house. Insurance is paying part and we are paying the deductible plus the upgrades not covered by insurance. Under a section entitled "Claims by subcontractors and suppliers" in the paperwork, it indicates that if a subcontractor or supplier who furnishes labor or materials is not paid, we might become liable and the property subject to a lien for the unpaid amount. It states to avoid liability, I should 'withhold or cause your lender to withhold 10% of the amount of payments made for the work performed...' It says I should withhold 10% for at least 30 days. From what I can deduce, this is to make sure the contractor pays all bills. I am trying to make sure I understand this fully, but the Q&A on this page, written I think with the lawyer in mind, makes me more confused! Can you please clarify?
