Robert Jones Posted September 21, 2011 Report Posted September 21, 2011 I see this every now and then and I just don't get it. Why install the rake flashing on top of the shingle. It's not like the water can't run under it. Click to Enlarge 65.93 KB
Marc Posted September 21, 2011 Report Posted September 21, 2011 I wonder if there's a second rake flashing that's installed under the shingles. Marc
Robert Jones Posted September 21, 2011 Author Report Posted September 21, 2011 I didn't see one Marc. It looked like the current shingles were installed over an older wood roof.
kurt Posted September 21, 2011 Report Posted September 21, 2011 That's old school hillbilly method for covering the edges of multiple roof layers.
Jim Katen Posted September 21, 2011 Report Posted September 21, 2011 That's old school hillbilly method for covering the edges of multiple roof layers. Yeah, that's pretty much it. Of course, it guarantees that water will run between the layers of shingles.
kevinbrown10 Posted September 21, 2011 Report Posted September 21, 2011 Yes, I agree with what you all have said as I think there is a rule of installing flashing over shingles that water runs downhills but sometimes the second rule creates contradiction with the first one.
Marc Posted September 21, 2011 Report Posted September 21, 2011 Yes, I agree with what you all have said as I think there is a rule of installing flashing over shingles that water runs downhills but sometimes the second rule creates contradiction with the first one. I don't understand your post in regard to the 'second rule'. Care to clarify it? Marc

allseason Posted September 21, 2011 Report Posted September 21, 2011 That's old school hillbilly method for covering the edges of multiple roof layers. Yes, saw it twice last week.
Chad Fabry Posted September 21, 2011 Report Posted September 21, 2011 Uh, wouldn't it make more sense to install the rake flashing before the final layer of roofing? I've seen folks install rake flashing like that to stop their IKO shingles from blowing off.
kurt Posted September 21, 2011 Report Posted September 21, 2011 I've seen folks install rake flashing like that to stop their IKO shingles from blowing off. Another olde school hillbilly methodology.
hausdok Posted September 22, 2011 Report Posted September 22, 2011 Hi, See it every fifty or so older house. It's usually installed on the south or west gable here 'cuz that's where the wind comes from and they're trying to prevent water from being forced under the shingles into the roof plane and attic below. It works when the nails are daubed but if the nails aren't daubed as Jim pointed out it sends water between layers anyway. Most roofers around here don't use drip edgings at all. If they do, they put them at the rakes and not at the eaves and most don' t have a clue about how to install it properly when they do install it. ONE TEAM - ONE FIGHT!!! Mike
