Three weeks ago we had roofers do a tear-off (3-layers) & put a new 3-tab 30 year roof on our old Chicago bungalow. They pounded the old nails back into the wood rafters (didn't remove them) & used 1.5"-2" nails thru our old pine ceiling (unfinished attic that we use 3 seasons). Problem: numerous split wood, broken wood, rotted wood that they didn't replace, sagging shingles where they pounded so hard that it broke the wood. Roofer wants to cover inside with sheet metal to hide the problem - we want another complete tear-off & replace broken rafters, etc. (then possibly put sheathing over to protect). The attic now has nails protruding through it splitting a lot of the wood. What worries us is the long term - how will it survive Chicago winters / how will it look in two years from now, etc. The roofer says don't worry about it, they will snip off the nails, cover the holes with the sheet metal and replace about 3 ft of sagging boards. We have found approx. 35-40 spots where the boards are sagging, split & broken. They even forgot to center the breather vents for the roof -they put one on an angle the wrong way!
We almost would like to get another roofing company in to redo the job / put new wood rafters & replace the old flashing for windows & chimney that the original roofer forgot to install (then send them the bill for the job). Any thoughts on shoddy worksmanship, etc. So far no rain inside; however, we have seen several areas of light coming through the dormer walls where they obviously forgot to put down the roll paper!
