I wanted to ask this question again to see if anyone can advise me on what will happen when you shingle over warped sheathing.
I had my roof redone and roof_lover it does look great but I have noticed all the areas that still have some bulges or waves after the new re-roof is exactly where the first roof installers replaced sheathing. So either they didn’t do it correctly or the sheathing is warped. One of my request before the new shingles were installed, was to inspect the sheathing. The new roof installer said that he would warrant it but this was a big reason why I had the roof redone. The other reasons, of course, were because the first installers didn’t install anything correctly.
Should I demand that the new installers redo the areas that have the faulty sheathing? What are the long-term issues with this? thanks.
