How do I know that the flashing for my chimney is done correctly? I just had my roof reshingled and the roofer also redid the flashing for the chimney. However, the new flashing is not as high as the old flashing, and consists of smaller alumninum pieces that look like they barely overlap. How should the flashing adhere to the chimney? Does anyone have advice? Would appreciate it.

There are a couple of ways to do flashing. Most common is a two part deal. Ther is a base flashing or step flashing that is an "L" shaped piece intertwined with the shingles on every course and hsaving a leg extend up the chimney. This leg is facing uphill to catch water and cahnnel it into the house so it is covered by the second part, which is called the counterflashing, set into the masonry. Normally, in an olkder roof as youdescribe, the counterflashing is left in the chimney and the base falshing is replaced with the shingles.

i cannot tell from your wording but it seems as if there was no counter flashing yo start with

Excellence is its own reward!
