Sorry, I'd have to be there to see it to give you a bullet-proof response.

but is it easy enough to take cap off and then replace? we don't have to cut a new hole as there is already one there. thanks much. p.s. we are doing this today, so hope to see a response! :)

Same technique. Make the slit in the metal roof half way up the flashing. The slit in the roof is exactly the same width as the flashing.

Informative. Thanks! Any experience w. metal roofs? We need to replace a duct vent that vents straight up from 1st floor dryer up through 3rd floor utility closet to metal (sloped) roof. Somewhere along the length, its become disconnected and does not vent properly. We'd like to use existing roof vent cap. Is it pretty straighfwd to remove vent so we can pull out old duct and slide in new one? Concerned about keeping metal roof integrity as it was just scraped and resealed this summer. thanx!

You sure are confusing me. Your first comment states that I did the job wrong - and that you have a different method. Uploading a video to YouTube is easier than installing one asphalt shingle. Since you have a lifetime of roofing experience, you should share it. Are you going to take your knowledge to the grave with you? That's unacceptable in today's world. Surely you can take the time to do it if I done it. It's our obligation.

I agree with you, the flashing is working properly and it is not leaking because the pitch of the roof lets the water go fast and the snow does not stand as on a low slope roof. i've done roofing half of my life and what i wrote is based on my experience, sometimes sealant might not be necessary but doing so give peace of mind. Instead of caulking, there a large variety of products, i use ice-guard around every pipe, chimney, flashings, i.e. Unfortunately i've never loaded videos or pictures.

Thanks for your comment. This flashing doesn't leak. It's been in for several years through driving rain and deep snow. I went to your channel and there's nothing there. If you are an expert roofer, how about sharing your knowledge with videos? Show us your methods. The method for installing the flashing in slate or wood shakes is the same. If you disagree, then tape your own video showing us how you do it.

i'd like to see this professional man installing those things either on slate roofs or cedar shakes, LoL. Another thing, in the video he missed some important details as using caulking on the top part of the flashing. In winter time, it might leak, guess why?, well, snow accumulate on the top part of the pipe, later ice damns start growing under shingles, the purpose of the caulking is to stop those damns. he used caulking on exposed nails only!!, no good.

Indeed they are. Rock is not too bendable, unless it is heated to about 1,500 F and under maybe 50 atmospheres of pressure.

you are lucky you have such pliable shingles! I have slate shingles on my house, a real PITA to work with.

It's more than just "my idea". It is taught in journeyman school, it's on their tests, and if you're a roofer by trade, you would never dare do a roof without gumming the valleys, chimneys, vents, and so on. Similar to vinyl siding - you would never do a job without papering it all first. Especially on lower slopes, water creeps under shingles and vents. A gum bead pushes it back out. That's all I can say.

AsktheBuilder (August 29th, 2008 @ 12:47 am)

There are hundreds of thousands of roofs out there that have all of those things and *no* gum that are leak-free. I am not saying your idea is bad. I am trying to get you to have an open mind about the facts. If I have no gum and no leaks, then why must I do it? Don't answer that you think it is a good idea. Answer with some hard science.
