This is a Florida Re-Roof in Polk County Florida. the contract calls out the contract amount, that was signed by the property owner. The lumber that we discovered was input into a change order and due to the fact that we are unable to obtain approval for the change order at the time of the roofing being removed and repaired. We have the language in our contract that specifies this as well as the lumber pricing by piece or linear ft. When creating a lien for the property will the contract language and change order that is not signed by the owner hold up in court with substantial imaging and documentation of the lumber costs and replacements? Please advise. Thank you
