Roofers did a good job. Showed up on time. Two vents were not installed at same time of roof. Forgotten. Installed next day. Clean up was not done efficently. Nails left on porch and in laneway. Magnet was not used on lawn to pick up nails. When estimate was done, he did not take into account an extra layer of shingles like 3 other estimaters did. Did not inform us of increase in cost until after job was done. Even though we were home all day. I think this is called "blind siding the customer". He then pointed out a clause on contract to cover the increased cost. Finaly came to a reasonable solution.
Always read contract completly.
