After watching this video I wouldn't hire you even IF I felt like I couldn't do this myself.

Great job guys thanks. Only thing... I don't think you caulk the low side of the vent so any trapped moisture can drain down and run out above the shingles.

[pilotguy]

I'd have to agree that this was made a lot harder than it needs to be. I also agree with This old House install

It's amazing how much water can leak down around a nail if you don't caulk it! Great Video!

Dude, read the instructions that came in the box - they tell you step by step how to put the thing in. As everyone else asked, why is this guy pulling out shingles? Just cut them in place. you know the exact center, meaning you can mark the roof and get the hood out of the way while you are cutting the shingles to fit. Caulk line on the flashing should not be a zig zag. This probably turned a 20 minute job in to a 5 hour slog. And the shingles aren't up against the sides - this thing is going to leak, and it looks like crap. This is not good information, and should really be deleted - you definitely don't want anyone who might hire you to see anything like this, and don't want to encourage anyone out there DIYing this to start pulling out rows of shingles. Just read the instructions that come with the

Several things that you've done wrong... never caulk the bottom, so water can escape, for one...

[idontcaresapo]

Dude. What are you doing this job is so easy you don’t have to pull those shingles out

[MattJonesYT]

Not clear to me why you removed the shingles then put them back on. Seems I agree with the other poster that the This Old House video is a little more straightforward.

So who does this type of work-roofers, plumbers, carpenters, hvac people, who and how much?

[fahmywaleed]

I am missing the collar piece, can you paste a link of it from lowes or homedepot, thanks for the video

[RobHTech]

Good vid. Not so sure you need to completely remove the shingles. Just mark, cut out, slide under, seal. Also, some shingles simply won't come off like that because they have tar holding them to the roof.

At least he's not using a ball pen hammer. What year did gloves start being made

[misodinamosa]

Is it best not to have a back draft damper for a stove?

[rockete]

wow all wrong. guaranteed leak in 6 months .
Instead cut the hole through all shingles - do not detached. Then remove the one or two nails above the hole. notch top upper shingle. slide vent in - attach to roof. flash cement appropriately and your done.

[bondpit]

Why are you removing shingles? No need to remove a shingle tab. Caulking should not be run across the bottom and nail heads were left un-caulked. Wrong, wrong and wrong.

[miztrusa]

Bit overboard with the incorrect culk to use but to each his own.

[dotjoseph]

Sheesh adjust the hole to a better spot for the top shingle, the drill hole is just to get you in the right stud bay.
