I am a sub contacted for a builder in houston, TX. I roofed a house and was handed an inspection report. I corrected the issues on the inspection report and completed the repairs and damages caused by other trades as well. I drove by the neighborhood and noticed the house getting a new roof. I text the builder and asked what was wrong and if I was getting back charged for the roof replacement and he said yes we can talk on Thursday after Christmas. Is this legal? Can they do the work and back charge me for something that I was not notified about or given the opportunity to repair?
