I am getting reroofing bids for my 25 year old house in Northern Virginia, and I have gotten conflicting advice regarding installation of drip edge.
The first roofer told me he does not recommend installing it because it is not necessary when the shingles are installed properly, and can cause the shingles not to lay straight if the underlying roof structure has irregularities.
The second roofer said that was nonsense, and they always install drip edge.
Both of these roofers have highest ratings in a local consumer ratings service (Washington Checkbook).
Any advice would be appreciated.
