I've spent countless hours trying to find multiple comments about how drip edge and gutter installation should work together to prevent damage to fascia.
New roof with type D drip edge installed last week,
Next day new gutters put on. Noticed gutter installer was putting major bends and waves into the drip edge. Raised drip edge and shingles up about over an inch along a six foot width. He also was putting all screws into the vertical edge of the drip edge flashing, bowing it in about every 16 to 25 inches.
I got pissy with him, he said it was required to get the gutters in the right place.
Basically found out the roofers had installed type D drip edge tight against the fascia, even though being instructed to leave an air space of 1/8 to 1/4 inch.
What do y'all do with drip edge with consideration for seamless gutters being installed afterwards?
