The causeway connecting the house to the new garage/in-law suite needs a roof. Tom Silva starts off his roofing lesson with the apprentices by stressing the importance of properly applying both the membrane and flashing to prevent water leakage. Then they start the first course of shingles.

How to Flash a Roof | This Old House
https://www.youtube.com/user/thisoldhouse/
And what about in the winter ?? If there’s a gutter should’nt the snow go between that gap ??
Underlayment is above or below drip edge??? I keep seeing different techniques. Also people saying it depends on your State. Which is the better method regardless of which State you're in?
Great video but why would the paper go under the flashin
where the heck do you get drip edge with that wide of roof metal. Almost all of it I find is like 2 inches. Can hardly get a nail in it on the roof.
If I did my drip edge like that. It would be one solid Hornets nest around the entire house.
Drip edge goes on first, then the I%W. How old is this?
At least he’s using a real drip edge(F) not rake(C)
Never disappointed with how massively unhelpful the comments on these TOH videos are. People loving to disagree and criticize, but then either don't back it up with the "correct method" or they try and their explanation is self-contradictory or too subjective. Comes off like dudes swinging themselves around more than trying to be helpful.
"Do it the opposite way Tom does it."
"Why?"
"Cause he's wrong."
"Nah, he's 90% correct, but the 10% he's wrong will cost you your life."
"Nah, he's right, but the way he did it is wrong."
"Nah, he's wrong, but the way he did is right."
"You're all wrong! Do it this overcomplicated way that doesn't make sense outside of my climate region and even then expect to redo it every 10 years, even though that makes zero sense for a $20k roof."
Makes me absolutely LOATHE working with contractors. No two agree with one another and you constantly feel like half of your house is on the verge of imploding.
Should that be gutter apron for gutter area and drip edge on rakes?
Is flashing 4 x 4x 8 ?
The two No-Nos is exactly what roofers did to my father's house, which now has rot on a lot of the wood.
😢
They do not sell a proper dripedge (like we see here) in the reno stores.
Should have mentioned spacing the drip edge out to accomodate the gutter being tucked in behind it!
you are a perfect teacher.
Thanks for posting. I am not a builder, so I learned several things for a new 2 story building I am doing. I would have made the mistakes that this gentleman brought up.
We have pvc fascia board now, so who cares
Yes, this is true.
But most often the people in the videos are showing you what is “ to code “ in their state , city etc….
It isn’t always the contractors who don’t agree , it’s the ones who set code.
With all do respect, where i live 9 times out of 10 there is an aluminum fascia covering the fascia board. Therefore worrying about the water rotting the board is not an issue and the water drips off the bottom of the aluminum fascia. The aluminum fascia even has a protective design to stop against water wicking around and causing problems. Thereforw i choose to install the shingles flush with the drip edge to reduce the risk of ice in the gutter or wind lifting or breaking the bottom of the bottom coarse
Bruh the Steph Curry and Kevin Heart commercial they made me watch before I got here got me lmfao😂
My only issue with this is nailing the step to the wall. When those shingles are replaced down the road, if the reveal is different, the step won't line up and will have to be adjusted. If you nail it to the wall, the siding has to come off to do that. One nail, in the deck, on the upper corner away from the wall is ideal.
One of the biggest pissers in all of roofing is having to remove the siding to fix the step flashing.
The biggest issue I see on new homes is they install the drip edge flush to the fascia and leave no room for guttering to slide under the backside of the drip edge. So they just install gutters over top of the drip edge
very informative—thank you!
This dude is a great teacher
I don't like the nailing step flashing to the wall. Next roofer might need to move it up or down, I dont see the need to do that, but some do nail it to the wall. I also on my roof put the flashing under the wall wrap and over the synthetic roof underlayment, that Tyvek Protec 200. that way any water getting under the old aluminum siding flows out away on top the flashing and not get behind it. Was not hard to do when the siding is off. And the step flashing needs only one corner nail in it away from the wall.
Did the same on my wall to roof but used Tyvek Protec 200 ran 2 feet up the wall. Then wrapped the wall. Where we live we get no snow. Then I made step flashing out of aluminum 3.5" legs and 8" long cut from 14" trim coil. worked out fine. I also used some Dynaflex 230 black caulk anywhere that seemed it needed some. My house built in 1973 has aluminum siding and no J channel along the edge, which I like the look. I replaced the exterior sheet rock with 1/2" plywood.
where is the ventilation gap? osb will rot in a couple of years.
Where does top of gutter go in reference to face of drip edge? Below or behind ? & where does top of facia metal go in reference to drip edge and top of gutter?
How do you keep the facia trim tight if not using a facia board?
this type of drip edge is better just on gable ends..strait runs you need a good 2×3 flashing for when you install gutters
Thank you Tommy for sharing your knowledge I wish I was 20 years younger
Would the building inspector sign off on a drip edge being improperly installed.?
I see your drip edge has alot of nailing surface.. what im seeing at my local supply store only has 2" nailing surface.. where would i find the drip edge you are using in your video ?
I have a roof being done right now. The product manager decided on his own not to replace the drip edge. The existing drip edge was half the length that it should have been and wood was showing. Idiot! I am making them replace the drip edge. My question is should they take off the older drip edge or put new drip edge over old?
RIP Austin, gone way too young😔
Is it wrong to nail the step flashing to the chimney? My understanding is that the chimney and roof expand and contract differently and for that reason the step flashing should be nailed to the roof and not the chimney wall. If the step flashing is nailed to the chimney the flashing will be pulled by both the nail in the chimney and the tar on the shingles.
The things we do to fight water entering our nest!
As long as flashing is done correct, is it OK if the shingle doesn't overhang it that 1/2 inch?
great video
so when you are trying to replace the facia the problem I have that NO ONE addresses is that there are 5 million nails coming thru the drip edge into the top of the facia, so when you try to replace the facia all those 5 million nails prevent the facia from c going up tight to the plywood.
How do you remove the nails? I've tried a jam saw. a nail cutter or just pushing them all up and out…way to time consuming.
Anybody have any ideas?????
Just use 45 degree drip edge
