Hello- after lifting some of the layers of the old porch roof a contractor decided to place all new plywood ON TOP OF the old roof, then W & I, then shingles. I argued that we had discussed my desire to have the old roof removed, rotten sections repaired and then a new roof installed. He insisted his idea would provide a much more sturdy roof. I was so upset it took me time to search your site & then call a friend to come & talk to the contractor. UNFORTUNATELY my friend was persuaded that this was OK. Last night it rained and water pooled in the exact place the leak had been. The contractor completed the job in 1 hr. this AM. When he presented the bill, I refused to pay yet. If the water pooling continues, do I have legal rights to hire a different contractor to remove ALL of the roofs and start again? And not pay this roofer? Was this an appropriate method to repair this roof which had rotten under-boards and leaked?
