I am rennovating and old house, part of the work being done includes the replacement of a roof over the back of the house (back 2 rooms)...the contractor has had to tie the new roof into the old roof and in doing so the new roof is not exactly level... there an easy remedy?

The felt has been applied but no shingles have been applied yet...

I appreciate any information.

I have done the same thing. If you just roof over the different levels, it will be visible. The fix depends on the amount of adjustment necessary. For very slight 1/4 inch heigh difference, you can lay a layer of shingles along the lower side, over the felt, to ease the transition. When you shingle over the "shim" the transition will not be visible. If the height is off by 1/2 inch, you may be able to lift the roof sheeting to match height using wedge shims, then renailing the edge. You need to hit from inside the roof deck to slightly raise the sheet to match, then use the wood shims to hold the height. This can be carried over 2 trusses or rafters to make an invisible height transition. If your height is off by more than 1/2 inch, the planning and construction is off and your contractor should fix it.
