I called Overtime after another company failed repeatedly to fix a roof leak that was causing serious damage to our upstairs hallway wall and ceiling. Peter, the owner, came with his crew, identified the issue and repaired the dormer to roof line with rubber membrane, flashing and new shingles. And doubled up shingles over a spongy area that the roof line was channeling the water to. Three days later we had a deluge and the inside was nice and dry. First rate work and clean up. We will have Overtime redo the whole roof next summer.
