Re: DRIP EDGE FLASHING MISSING
Required by the IRC, but I don't know how far back the requirement goes:
R905.2.8.6 Drip edge. Provide drip edge at eaves and gables of shingle roofs. Overlap to be a minimum of 3 inches (76 mm). Eave drip edges shall extend 1/2 inch (13 mm) below sheathing and extend back on the roof a minimum of 2 inches (51 mm). Drip edge at eaves shall be permitted to be installed either over or under the underlayment. If installed over the underlayment, there shall be a minimum 4 inch (51 mm) width of roof cement installed over the drip edge flange. Drip edge shall be mechanically fastened a maximum of 12 inches (305 mm) on center. Where the basic wind speed per Figure R301.2 (4) is 110 mph (49 m/s) or greater or the mean roof height exceeds 33 feet (10 058 mm), drip edges shall be mechanically fastened a maximum of 4 inches (102 mm) on center.
Also required or recommend by some manufacturer's installation instructions.
Note that the code allows the drip edge to be installed over the underlayment at the eaves (to prevent high winds from stripping the shingles), this conflicts with some manufacturer's installation instructions.

Re: DRIP EDGE FLASHING MISSING
Without going back to research it, I think it was added to the IRC after 2006. Many of the shingle manufacturers required it for several years before the IRC did. When I was in Mississippi I seldom found drip edges on homes.

Re: DRIP EDGE FLASHING MISSING
This must come up about once a year
I write it up every time I do not see it. There is not a good reason to not have it on and can think of a few reasons to have it on.
Just my opinion.

Re: DRIP EDGE FLASHING MISSING
Drip edge? What's that?
I would call for repair, install a drip edge flashing, in that case, not enough overhang.
We run the shingles into the gutters up here, were it rains for 11 months of the year, and I seldom see a proper drip edge flashing. With plenty of overhang, the sheathing stays dry and the gutters don't leak.

Re: DRIP EDGE FLASHING MISSING
I've seen roofs with and without drip edge. With and with out paper. Drip edge above and below underlayment. In my experience drip edge is needed. It might not be a building code requirement but I'm sure manufacturers require it for warrantee. Metal drip edge below the ice & water underlayment can and has caused ice dam leaks. I've found the best way is to nail metal drip edge flashing over the ice & water. If possible extend the ice & water over the face and inch or so.

Re: DRIP EDGE FLASHING MISSING
Hey Bert, On a house with ice dam in the gutter. When the temp warmed up it started to melt but the ice burg didn't move. The metal drip edge should have been set in roof cement but wasn't. With no where to go the water found a weak spot and went behind the drip edge.

Re: DRIP EDGE FLASHING MISSING
Certainteed has this in their installation instructions. Seems like you just need a quarter inch more overhang without a drip edge. So, is it follow code or follow manufacturers installation instructions???
Certainteed's installation:
STARTER COURSE:
1. Use CertainTeed Swiftstart or Universal Starter or a starter course
consisting of the shingles from which the lower 5" tabs have been
removed (Figure 10-6). Remember, the sealant on starter courses
should lay as close as possible to the eaves edge of the roof.
2. Cut 5" off the length of the first starter strip and apply the resulting
31" piece at the lower left corner of the roof. This starter strip
should overhang the rakes and eaves 1⁄2" when drip edge is used,
or 3⁄4" when no drip edge is used (Figure 10-7).
3. Continue with full-length starter-course shingles along the eaves

Re: DRIP EDGE FLASHING MISSING
OK, I can see that - it was the "1 in" that was confusing me; typically if "ice-damming" is a concern and the drip edge is above the underlayment, the manufacturers of waterproof shingle underlayments recommend wrapping the WSU well down below the edge of the gutter (first attachment below, from the Certainteed Single Applicators Manual).
Around here (Chicago) IMO best flashing practice at eaves with "conventional" fascia/soffit profiles and ice-damming problems (to the extent that eave flashings can "solve" ice-damning) is a double layer of flashing and a "high back" gutter profile:
- Leak Protection: Swistun Inc.
YMMV, depending on eave design and geographic location.

Re: DRIP EDGE FLASHING MISSING
WC Jerry,
Down here in the state which experiences high wind events there are two other thing wrong in that photo which are visible, making that 3 things which are shown as being wrong - but for locations other than high wind event areas, only that one is going to be consistently wrong from area to area.
As you've not doubt noticed, I had not said anything above (other than my response to your post) and ...
... I taint sayin' nuttin' 'bout nuttin' else ... already gave the hint away by mentioning which photo ...

Re: DRIP EDGE FLASHING MISSING
The roof felt is not under the rake drip edge
(Although, it does look like something is, could be protection for ice dam. We don't have much need for that around here, and I have never seen any so I could be wrong.)
At the corner, the rake drip edge should be over the eve drip edge, not under it.
Shingles are not secured (nailed) at eve's edge.
Which means that the starter course is improperly laid.

Re: DRIP EDGE FLASHING MISSING
Drip-edge is required to kick away any moisture that accumulates on the decking running down the slope and stops the face board and other facing materials ( cladding ) from prolonged exposure to moisture.
It must be under the start sheet. Not on top.
Suspect: no drip-edge around the parameter of the roof decking.
Effect: may cause degrading in materials and surrounding structure if left as deficient.
Recommend: Licensed roofer install drip-edge around the perimeter of the decking.
Drip-edge is use as a kick out flashing to direct moisture away from the face board ( in the case ) so prolonged moisture exposure does not effect the face-board and any materials and structure directly bellow it.

Re: DRIP EDGE FLASHING MISSING
Ted if flashing and materials are applied in a proper fashion ( as accordance to manufactures specifications ) then every thing will work fine.
Being a roofer and having many years of cross trained repair and new building experience behind me now, have only used plastic cement or other forms of caulk to fix a mess that would not have been a mess if they would have followed the manufactures guidelines and been apprenticed properly.
You must redo you roofing part of you education please.
Flashing will be your biggest hint if that section or the trade was performed well. Flashing is the least understood when apprenticing new tradesmen.
Watch out for flashing PLEASE!!

Just got up and was blinded by the glare from my sun burnt nose (fathers day on the lake). The glare may have interfered with my view of the drip edge, but it doesn't look like it extends 2" on to the sheathing.

Re: DRIP EDGE FLASHING MISSING
Not necessarily ...
And you certainly would not want to do that in Florida, or (I would think) other high wind areas.
I have to say that when I saw Rick post this: "At the corner, the rake drip edge should be over the eve drip edge, not under it." ... *I* thought he nailed it, but I see that *I* was wrong too.
So now I have to wait like everyone else and see what WC Jerry says.
Then Ted said "The eve drip should be coated with roofing tar or equivalent to keep water that may be leaking behind shingles above and then under the eve drip.", which is one of the things I referred to, the rake should also be sealed that way. Then, Ted was in Florida for a long time before moving to Texas, so he would know.

Re: DRIP EDGE FLASHING MISSING
I dunno. I'm going to guess it's galvanized flashing with an aluminum roofing nail securing it.
For what it's worth, the 90° no lip drip edge around these parts is not completely flat - it still has ridges like the 8" standard drip edge I use. And even then the no-lip stuff isn't typically used with shingles and gutters. The product in your photo just looks like a standard piece of flashing. Since I use a self-adhered membrane at the eaves and rake in this cold climate (such as Grace Ice & Water), I don't actually nail through the drip edge, I just tack along the edges.
Speaking of which, what product is that under the drip edge in the photo? And how many layers are on that roof? All of the starter strips I've seen around here are a single layer thick - that looks to me like four layers total, making me think there's no starter strip and just two layers of shingles on the roof. Unless those are three-tab shingles...

Re: DRIP EDGE FLASHING MISSING
I didn't bother reading all responses to see if this has been answered, but I'm always up for a good quiz. It looks to me, in the last photo, that the rake drip edge should be on top of the eave drip edge... assuming you can call that flashing a "drip edge" What do I win?

Re: DRIP EDGE FLASHING MISSING
EVE drip flashing is a nonsense word.
Does it kick out or away the moisture? No
Flashing are there to protect a part of a system.
It only protects the face of the plywood end.
Its a common mistake taught to roofers.
It is a cheep no use product that does not fill any required flashing recommendations.
Some one posted to use plastic cement. FOR WHAT.??????????????
Drip edge kicks away the water that will otherwise continue run down the face-board and back up underneath the eve.
Simple.
The photo is a mistaken process that was being used by a roofer that is inexperienced, untrained in the proper installation of roofing product,will void some guarantee. And is cheep.
Sorry but that is all.

Please look at the photo.
There are several problems.
Deficiency's.
Suspect: No VDR or moisture shield.
http://http://www.surroundtypar.com/
If you look at the photo the is ZERO DRIP.
The drip does over the ply or deck board end.
There is zero.
Suspect. Butt joints line up. The starter course is wrong.
Please guys I did this for to long to take lip from 1 person here. Do your roofing part over again

Re: DRIP EDGE FLASHING MISSING
Yes it is ... that is why we are referring to EAVE drip, also referred to as just "drip edge" because it is also applied to the rake overhang, etc.
Does it kick out or away the moisture? No
It only protects the face of the plywood end.
It is a cheep no use product that does not fill any required flashing recommendations.

Drip edge kicks away the water that will otherwise continue run down the face-board and back up underneath the eve.

Re: DRIP EDGE FLASHING MISSING
Nor are the manners.
If one does not see a deficiency in the gap between the deck and the EVE I am truly surprised.
A manufactured drip from a metal shop is the answer if the store bought drip does not fit.
Also the starter is wrong but why stop there. The shingle over hang is too long. Gee where do I start because I see many problems here.
No drip, gaps, starter course wrong are the first signs to look deeper into this system.
Any HI should note that.
The water will work its way backwards under the bottom of the shingle. With the right condition IE; wind , or a back pressure in the unit, it will force moisture behind the eve and onto the backing of the face-u -board. Opps sorry trade talk. The fascia.
Depending what materials where used this moisture may cause advanced elevations in humidity in the material and surrounding material and systems. A rapid degrading or deterioration of materials used. IE; MSB, OSB, Particle board, press wood,
Once over the relative humidity levels of 17%, organic life starts to take hold. Mold being the first hypothesis.

Re: DRIP EDGE FLASHING MISSING
Mr. Young, I think perhaps we are talking about different things here.
No one has suggested that the original picture posted by Mr. Van Fleet did not have many deficiencies. Indeed, it would probably require less work to enumerate what isn't wrong with that installation.
After Mr. Van Fleet's query, Jerry McCarthy (aka West Coast Jerry) posted a set of photos and hinted at there being something inappropriate with the third. The thread then took a turn towards divining to which defect Mr. McCarthy was alluding.
In addition, rtadja had made the claim that placing the eave drip edge under the underlayment can cause water damage in areas prone to ice dams, and discussed the methods by which that could happen. One of the suggested remedies was to place the drip edge on top of the underlayment and embed it in roofing cement. Mr. Thomas related that in his area the best practice is a double layer of flashing and high back gutters.
In short, I think there are several conversations happening here, and perhaps the suggestions and remedies proposed in one are being mistakenly confused with the problems presented in another. We'd likely all do well to slow down, take a deep breath, and re-read before we hit "Submit Reply."

Yes Mr.Walker. You might be stating the obvious.
It still does not give an individual the right to exert is limited social skills on someone obviously challenging his conclusions.
It should have been meet with a question , not a pomposity of comments about my statements and my remarks, with out explaining his conclusions or hypothesis so I could defend my point.
Instead he points to a man made flashing ( cheep cost cutter )( maybe saves 20 dollars for the tavern )
I can read and say his assumptions where belittling a fellow HI.

Re: DRIP EDGE FLASHING MISSING
Ted, I agree with you in principal. However, We all should use caution when quoting codes in our reports. In a local jurisdiction a home inspector inspected a house built in 1985 and quoted quiet liberally violations of the 2009 code edition. Which resulted in the buyer refusing to buy the house and the seller filing suit against the contractor that built the house and the Realtor that was handling the transaction. In short the inspector has already lost his case at the mediation hearing and there are two other lawsuits pending against him in the case. It appears he is going to lose everything.
