Drip Edge

gutts-1

Why do roofers almost always insist on putting drip edge on tightly to the fasia board. My gutter company has to slide all our gutters behind tight drip or install some form of flashing. We did 40k ft of gutter last year and maybe three roofers got it right. Guys, I know the faster you get to the ridge the quicker you get paid but we are only talking a 1/2" The gutter guy has got to make a living to you know.

Here is another one for you:

First I put on my gutter apron on the eave. Then I put the style D' roof edge on the gable and cut it so it meets up with the angle that the gutter apron created. This leaves a snip that a gutter installer would have to cut off on the style D' if he runs his gutter past the edge of the roof. I do that so if the customer sees it before completion of job they don't think that the cut was short.
Does that method irritate gutter installers?

O.K. how about this one I had this guy who's super on the job did'nt like the way we were messing with the drip so much. after numerous conversations, on several different houses,[he just knew too much] I finally told my guys to put the gutter up completely below the drip. Well He called to tell me that the water was driping behind the gutter. I told Him the roof was wrong, THE REASON THAT IT IS WRONG IS if there were no gutters on these houses all the water will run down the fasia. Now if it were my house and I did not know anything i would say the roof must be too short.
A roofer that depends on the next sub to cover him will soon be let down.

I do beleive that the lower the gutter is the better protection from icing you have. If you cram the gutter way up the back of the gutter may be over [or at least even] of the fasia. This can lead to water into the house in witer. what I would like, I my perfect world, is to walk up to any house and see the drip out 1/4" away from the fasia. That way I can start low. with no worries.

So you cannot get your gutters behind the apron is what youre saying?

What I am saying is, the water from the roof should "drip" off of the edge of the roof. A drip edge should be just that.

For a roofer to get a uniform 1/4" (or is it 1/2", make up your mind) would slow him down. The purpose of this is to speed you up. So there's the dillema.

Gutters guys aren't the only ones to complain. When I do soffits and fascia. I notice how tight I put the drip edge. I have learned to keep it a little loose to fit the fascia on easily.
Drip edge really doesn't work goor for gutters. It is shaped wrong to make water drip straight down. It curls the water to itself and onto the fascia. All roofs should have a small L shaped piece of metal on top of the roof edge and under the I&W. It would be a piece about 3 inches wide with a 1/4" bend on it, so when the water hits the edge of the roof it goes to the edge of this metal and drops straight down.

Thank you mjw. drip edge should be an edge where the water drips from. When I put "drip edge" on I make sure its going to work....Hang it out,starter course hung out 1/8" over drip. First course of shingles hung out over starter course 1/8" never a problem. Maybe if a "roofer" does not have time to do it right he should just charge more so, so he can make the time to do it right.

I have been hanging shingles over about 1/4", but I think a goode 1/2" might be better. I think that is what the shingle companies want.
Most style D roof edge though doesn't work well on steep pitches. It is hard to get it on for the roof and still have it somewhat loose. I think gutter flashing should always be used where gutters are to be placed.

serrano

The shingle edge is to hang past 1/2 to 3/4 on all roof edges,the water should drip off the shingle edge not the drip edge.There is no need to run the gutter under the drip edge.

AaronB.

One should not install T drip on a gutter edge anyways. The stuff is made for rake edged.

That being said, we do not rely on any metal to drip the water away. 3/4" overhang of both starter and shngle does this. The gutter apron only provides a measure against wateer blowing in behind the gutter.

Basic good roofing practice.

Thank you aaron b.
My original intent on starting this thread was to try to get some form of awareness out of at least some roofers.
If I installed a gutter and did nothing with the drip edge, on oh..60% of the jobs there would be a problem. the owner would call me up and tell me that water is going behind the gutter. I then would explain to him that the roof must be too short or something , call the roofer.
A 3/4" overhang on a 3 tab shingle will curl around after a few years. At least in ct. whrere it can get rather warm. I have seen trac housing where there was no drip edge and that is what happens. When the shingles curl like will the water will then run down the face. I can not remember any jobs with archs though.
I am talking about housing with flat vertical facia boards and low pitched roofs.
Who said anything about "t drip" anyway, I don"t know what a t drip is, around here drip edge is drip edge and rake edge is rake edge. Maybe they use T drip in Texas or tennessee.

River Rat Dad

They use "T" drip in section 3.6.1 Perimeter Edge Metal Figure 12 page 344 in the NRCA steep slope Roofing Manual.

AaronB.

So they do, RRD

I do not agree with their detail. On a 12/12, or even less, the 90 degree bend in the average store bought t drip will force the metal face to cant outward, and the flange to leave little bearing on the deck.
I have made t drip to accommoate the roof pitch, but this gets costly.

3/4" overhangs do not have to curl, guts, mine do not.

I too overhang the shingles and starter 1/2 to 3/4 past the drip edge. We use t drip at the eve partly because we buy it by the box and it comes in a lot of color options. My local supplier stocks 10-12 colors of t drip. I agree Aaron, it doesn't fit well on steeper pitchs, unless you flair it out. Thats what I do on any pitch more than around 6/12. I hand bend it out to accomodate the pitch. It sounds like a pain in the butt, but it only takes me about 20 seconds to do it.

Again, its all those swell color options my suppliers stock for t drip that I like.

Lets get real, surely you have not heard the age old complaint about that drip edge isnt tight it is sticking away from my facsia,will you fix that before i pay you mr roofer.you do your job and we will do ours my guys install gutters with almost all of our roofs and i have yet heard such a thing from them,sounds like another its the roofers fault i took so long or thats why your gutters leak,deal with it or get out of the business.

gutts-1

Ooohhhh
now that makes things perfectly clear finely a reason i can make some sence out of.
Thank You
I know you guys do not put it on tight just to make the gutter guy mad.

gutrman

We have learned to deal with tight drip edge. After some time you can get pretty good at getting it under with out too much work.

When our gutter hangs below drip edge that is tight, we will install flashing from the drip edge to the gutter.

I would not blame the roofers for tight drip edge though. If the sheating is not run past the fascia board far enough it would be about impossible to have a gap and look presentable.

I see quite often now that the drip edge is installed tight on purpose. They use it to hold the fascia tight on the face and nail just the bottom. They do this so they do not have to nail the face of the fascia and cause the rippling effect.

gutts-1

Thank You ALL for all the info.
Gutrman I feel the same way. But I like My box and I want everybody to jump into it. Some of the roofers i work for will hold it out for me, when they can. some never will. But what cfroofing 1 said about drip that's not tight raising a question, that is what i think is a good reason. Not it takes to long or "we never do" or you don't "need to".
gutrman : you know what I'm after a perfect world where i never had to address. Wether or not the water will go into the gutter or behind it. The water will always go into the gutter. We to, slide, bend, pull, and install drip strip. I have for 18 years.
