Hi,

I am getting reroofing bids for my 25 year old house, 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.

Thanks.

NRCA ( National Roofing Contractors Association ) Manual say
perimeter flashing / drip edge "should be considered" depending on
climate, amount of snow and rain. It Then says NRCA " recommends " its
use to allow water to drip off roof without affecting underlying
construction.
