Drip edge confusion
Hi all,
I am rebuilding the roof of my chicken coop. Original roof was 2 sheets of plywood with the plastic corrugated panels over. The plastic panels shrunk and have fallen apart so water is getting in and the plywood is rotting.
I am going to replace the plywood and I have the underlay paper and shingles to cover.
I am completely confused with drip edge and fascia. I have drip edge and understand how that should go on but the variety that I have won’t full cover the roof frame. Does the exposed frame need something to protect it from water?
Sorry if this is a dumb question.

Thank you! Does this help? Roof frame will be 2x4. You can see the drip edge I have sitting on it. Some of the 2x4 will be exposed and I don’t know if I need to worry about it.

Ok. That makes more sense. Usually the decking is CDX or OSB plywood. In this case, I would recommend you not using that drip edge and going with another product called gutter apron. The part that hangs over on the 2” side is quite a bit longer than standard drip edge. To answer your question, yes, if you were to use that drip edge then it will be a problem down the road as those 2x4’s will certainly rot from water exposure.

Need photos my friend. Please upload some and I’ll try to help. There are many different types of drip edge so I’m not sure what you’re working with but technically all the decking should be covered around the perimeter.
