I have just had a new extension built, I have had continual problems with the workmanship of the building company and yesterday we finally got to the snagging list. On inspection of the roof I noticed the felt has started to ripple (south facing flat roof) in a lot of places particularly the seam laps. Should I ask the builder to redo the entire roof or let him patch by slitting the ripples?
I suspect the problem is caused because they left the roof ply on the roof for two weeks while it rained. When they layed the felt they did not put new dry board on.
Many thanks in advance
