My decking wasn't replaced

Joseph from New Hampshire asked:

The contract for my home roofing project states~ "Roofer to remove and replace all decking" but instead the roofer applied thin plywood over existing decking. When questioned about this breach of contract, roofer then says, "Can't replace decking because of ledger board so we left it." This decision was not communicated to me until job completion. My question is what percentage of the total cost would have been the removal and replacement of the decking?? 25% ? 50% ? Thank you in advance for offering to help with this question.

Henry Staggs from The Arizona Roofer shared this:

As I understand it a ledger board is attached to the wall for a walk deck assembly. This indicated to me that this roof may be a patio roof? I am not sure why it would stop the roofer from removing sheathing?

If the contract says remove ALL decking then I would think overlaying it is not removing it. And why do they call for it to be removed in the first place? If the decking is damaged (which is usually why we want to remove it) then it will cover damaged decking ... not good.

I think this sounds like a problem and I would suggest they find a local roof consultant to come out and take a look. They can find one at the IIBEC site.
