john ruiz: is there flashing for different type of pitches on roof
rredman84: Your bottom row of shingles goes under the vent, the rest of your rows go over the vent base and you cut out then round shape as you go leaving the lower vent base exposed using the overlap method. You also should put ice and water shield over the felt before you lay down shingle. Its hard at first but once you do a half a dozen its easy.
FantasyMainframe: A plumb bob would make figure out where to cut the roof a snap...just a friendly tip :)
edwinclass56: Thank you!
Jennies Garage: Hi, this was just a video outlining the installation of the flashing. I installed the vent pipe and cap later (before the rain).
edwinclass56: Where are the two nails removed from the top? They were not replaced. Is the "vent cap" missing? Water will get into the house otherwise. Finished job?
Hearthman1159: The entire vent should be B-vent since it is located in an unconditioned space. I would have located the roof jack further down from the ridge and use listed elbows with supports. Sorry but work like this is job security for me. This is NOT DIY work as proven here.
MrCinimod93 .: its the only way we make them not leak plus it glues down the singles so the wind dont flip them back and snap them off in the cold
Jennies Garage: That's a good idea, and cheap insurance!
MrCinimod93 .: around here we put tar under the singles that are on top of the flashing if we don't the wind blows the rain up under and into the house
Jennies Garage: I use double wall just up through the attic and out the top. Below the ceiling single wall is fine. Double wall requires minimum 1" clearance to combustibles, and single wall calls for 6"
Jason D Jean: Does the whole pipe need to be dual wall, or just the section actually going through the roof?
michael amaya: The hole you cut is to small. You should have 1 inch clearance around your pipe. Also you should use dual wall vent pipe, b-vent. A cap and rain collar should also go on. Then nail down and cover with roof tar.
Richard Recupero: Awesome video I'm about to go climb up on a roof and do that myself right now charging a customer 1500 dollars
Jennies Garage: When I got the house, that's how it was; fully operational, but no vent! I heat with wood, so I don't use the furnace, but figured I should go ahead and install the chimney. Carbon monoxide poisoning anyone?
fingers967: id like to know how the tech that hooked that up with the central air and all missed the fact there was no venting LOL is it a new roof ..WOW looks like a garage .. sure hope it wasnt venting in there the whole time till this
Jennies Garage: Thanks for the kind words, good idea about gluing the tabs down.
Carl Smith: looks good ,a little mastic under the lose taps keep the wind at bay , better then some roofer would do, and save you money.
Jennies Garage: Good tip, thanks!
