Why not insert the flashing under all the shingles?

[AsktheBuilder]

@blanknot go back to 1:54 and start watching that section again. It's all about overlap. The metal flashing is providing plenty of overlap on the lower shingles and is being overlapped plenty by the shingles above it.

@AsktheBuilder but no matter what your probably not gonna have a leak but it is wrong...All shingle go over the flashing except, that go over the first exposed course..

[AsktheBuilder]

@dekonfrost7 Well, I've got news for you. The flashing is just like a shingle. You have part of a shingle exposed each course, right? That's why you can do it my way with only 20 -30 percent of the flashing exposed and they'll NEVER be a leak. You need to pay attention to how things really are built.

Thanks for the vidual vid, bud. Great for the DIY weekend warriors. One note, just don't let that piece you cut with the recip saw fall into the attic, or the homeowner is likely to find a nice dent in their ceiling.

@amigo1080 Under is preferred, amigo. I agree. Then put some on top to finish the job right.

Is sealant only needed over the nail heads? I would think it wouldn't hurt to put some under the vent flashing where it lays over the shingles on the bottom half to prevent wind driven rain from being driven uphill to the vent hole. FYI - I do home improvements but never roof penetrations so this is a legitimate question that I'd appreciate feedback on.

should i follow how this guy did it or should i follow the manufacture's instructions? The manufacture instructions required roof cement and uses lot more nails than what you have. You can see the instructions at Broan.com and type in model# 636

This video helped me to successfully complete the installation of a bathroom fan on my house a few months ago. What a difference! This will come in handy when I install a range hood, as well. Anyone considering adding a bathroom fan can find information on selecting the appropriate CFM unit at Broan.com.

Thanks for posting this excellent video, Tim.

I too appreciate the respectul discussion. I completely understand doing everything "by the book" on how to videos. It would really be a liability not to. But it wouldnt hurt to mention what climate zone you are in, what wind does to play a factor in windy climates, and in extremely cold and dry climate, would you even want that moisture escaping? Just to run a humidifier longer? Naaaaah. You go high up into the rockies, you take whatever moisture you can get, and drink plenty of water.
