But in post #16, he get’s it right! :shock:
What? I should read the whole thread first?
Silly me.:shock:
Paper goes over the flashing at the eave,** under **at the rake.
Correct. The only way to protect the sheathing as intended.
Over at eaves, under at rake.
No, think again please.
My mistake. I read the question wrong. My answer was referring to tar paper over drip edge at eaves, under at rake, not the other way around.
You and others as well. :shock:
I think many of us read the question wrong, Chris. I voted incorrectly but commented correctly…:shock:;)
No harm no foul fellas.
It is an example of how important it is to formulate poll questions carefully.
As long we know the correct way to lay it that’s all that counts. :mrgreen:
New Poll:
- I can read.
- I can’t read.
- I can read, but don’t understand the question.
- I’m dyslexic, so gave the opposite answer.
Correction made, Chris…:mrgreen:
At the eve, asphalt-saturated felt always overlaps the drip edge.
With a few types of synthetic underlayment, the manufacturer recommends that the underlayment wrap around the eve and drip edge be applied over that. This is due to wicking problems.
Since you won’t know what type this is, best to recommend that underlayment always overlap the drip edge at the eves, and call out anything else as a defect. If you turn out to be wrong, it’ll be understandable and (hopefully) no one will fault you.
Or, if it’s synthetic, you could say it’s probably wrong but confirmation would require a specialist inspection.
I couldn’t believe my eyes when I saw that Poll.
I thought I was in a dream.
Glad everyone got it straight.
I was worried for a bit. :mrgreen::)
Blame it on the “Dark Forces”.
In Florida, the preferred installation method is for the felt paper to be installed UNDER the drip edge on the entire perimeter (eaves and rakes), then a 4" strip of tar placed on the perimeter.
We have lower slopes here and high winds. That combination requires the edges to be sealed.
By placing the felt over the drip edge at the eaves, you also defeat the purpose of the starter strip.
Over the 100’s of roofs that I’ve torn off, any roof in Florida with the felt over the drip at the eave and no tar, wood rot is present.
One man’s meat is another man’s poison, or something like that. The same thing does not always work everywhere and generally we follow the manufacturer’s recommendations.
You’re right Kenton, doesn’t work the same way everywhere.
Are you trying to prevent ice dams, then I&W goes over.
Are you trying to prevent ice backup from the gutters, then I&W goes under.
Are you trying to protect plywood edge, then I&W goes under.
Wait, no ice dams in Florida, so all you use is #15 felt at best.
Install # 15 felt, drip edge on top and seal it with a strip of vycor if you wish if it makes you comfortable, it won’t matter unless you have a 90 mph wind anyways.
We have a few inspection tips, including drip edges, within the short video course: http://www.nachi.org/roof-inspection.htm
The course also includes a bunch of downloadable technical guides.
