What is the correct drip edge overlap for shingles
 
Does anyone know the correct overlap that the ashphalt shingles should be at the drip edge and eaves? The roofing contactors installed the first row of shingles to the edge of the drip edge only with little if no overlap on the drip edge and the water was leaking past the eavestrough. When asked he said that it was correct for the new percentage of fibreglass shingles? With the water still leaking down the fascia they came back and installed a wider drip edge under the starter row and explained the wrong drip edge was used for the width of the fascia boards??

Go on line and look up the brand of shingles you had installed and look for the install directions and down load them.
Theres not on single company that will say not to have an over hang.
Total BS!

Thanks, once the snow clears and we can get in the shed I will check the packaging as we still have some shingles left.

Majority call for at least 1/4" overhang past the drip edge.I put 1" off the rake line and 1"-1"-1/2 in the gutters.

Thanks, When dad and I did the garage roof we left about 3/4"to 1" overlap and to see the roofers leave very little overlap seemed odd..

IMO its irresponsibility since its a dead give away that they are not using lines,,which some do and some don't but they should pop at least one instead of following the lip of the drip edge trying to keep the roof straight.But judging from your half baked counter installation who really knows why.

Carpenters pattern too. Was this a roofer or a contractor who "did" roofing?

Probably neither :laughing:

Peter683 01-13-2013 04:19 PM

It was a contractor working on behalf of a roofing company.

And what does he say about all these concrerns?
I know I've tryed differant subs, tryed to work with them, old bad habits are hard to beak and I'm to old to waste my time.
Do it right or find some other sucker to sub off off.

We won't know until they come to check. Just had a look on the wrapping on the shingles and the overhang is supposed to be 1/4" to 3/8th's of an inch according to the manufacturer..

Sounds short to me but that sure is more then what you have now.
Also did they use Storm and Ice shield at the lower edges of the roof?
That's code here even in the lower US.

Peter683 01-13-2013 04:44 PM

They used the black tar paper along the first couple of feet..

PatChap 01-13-2013 04:49 PM

Not too sure where you are, but in at least Ontario, tar paper is still code. Has to be #30, though.
