Re: roof leaked on new house
Ditto to what's been said here.
To add .... Tar shouldn't need to be used if proper flashing and underlayment is done.
Without seeing what's what .... I would say a layer of ice & water membrane should be in place where the roofing meets the wall and should be running up the wall a fair bit before the flashing was installed.
If there is a fair bit of moisture damage on the inside ... I would think to remove the insulation to let things dry out .... depending on how bad possibly the drywall in this area.
On one hand it's a good thing this revealed itself now rather than after the home was finished and the builder moved on.
Just 2 cents worth.
