[@mikeh2291]

When I was a kid "This Old House" didn't exist because a TV didn't exist in the early 1950's at "Our Old House". I enjoyed watching my Dad do all sorts of repairs though, like sweating a steel pipe joint with a blow torch, a cloth and maybe lead back then. Blow torches were really "cool". I especially enjoyed getting on the roof with him. Mom would always have a fit when we did that. I'd like to know what Tom Silva's safety rope was attached to. I suspect it went over the roof peak to something on ground level, like the trailer hitch on his truck. Gotta use a rope that won't stretch much though. I used a safety harness on the job for many years. Should have used one years earlier but fortunately I survived that period of my life on the job.

[@j_dane9519]

Always love it when Tom Silva steps me through a project I'm about to take on. After watching this video, I installed a couple vents on my roof. If you're thinking of doing the same, here are a couple notes you might want to consider: (1) My shingles were much less cooperative than the ones in this video (breaking the seal (2:50) without breaking any shingles required a lot of patience). (2) Remember that your initial nail location is a bit arbitrary, so you can make it easier on yourself by adjusting the location so that the top edge of your shingle cut-out is right at the bottom of a shingle course. (3) It looks like Tom only removed the top layer of shingle. Other videos want you to go deeper. I don't know what's right, but be sure to give this point some thought. (4) Tom's vent cap didn't have a duct flange attached to it. This made it easier to slide into place (maybe he got away breaking fewer seals because of this), but it also introduces a condensation risk: moisture-laden air will be flowing (under pressure) through the open area between the flange nailed to the roof and the the vent cap and the plywood sheathing. A simple fix for this is to add sealant between the flange and the plywood. Incidentally, my vent caps had flanges already attached, but the attachments seemed pretty leaky so I sealant where they connected to the vent cap.

[@paultalanoa9513]

Peeling apart shingles is best when its warm outside. It helps soften the tar bead under the shingles. So you can slide in the new roof jack / roof vent etc..

[@NoName-sn1le]

you the real MVP, thank you for these notes!

[@NoName-sn1le]

what do you mean by point 4 you would like to see the base plate of the vent have a crimped piece to attach a vent hose directly to?

[@scottslotterbeck3796]

Tom did it correctly. When you reroof, you'd run the shingles up to the vent, then nail the jack down, then continue roofing. Just pretend you're water, and trace the path where it would go. If it hit the top of the jack, it will go around and flow down. Water can run sideways, especially wind-driven, which is why he sealed the shingles on either sides. I usually use a much bigger jack when reriofing, but that doesn't work well when you retrofit.

[@BobbieJeanM]

I wondered about his not putting sealant around the duct on the roof and attic side of it. Not sure if it’s necessary but something I would do just to be extra safe,

Thank God we had a GREAT young tour guide in his 20's who gave the 12 of us in our group MUCH confidence and I felt so relaxed through it all for the 2-3 hours on the tour. It was easily the MOST EXHILARATING moment of my life and I went back to the hotel a bit teary-eyed that I had accomplished something that I NEVER thought I could do. I also have large photos to remember the unforgettable experience. But I am now 70 and no more bridge climbs for me. I can go up on a step-ladder only so high before feeling a bit dizzy and can no longer go on the roof of my home.

If someone has already provided the following, excuse me for duplication. This is a superb video. Thank you for publishing it. A vent hood that is very similar or perhaps the very one shown in this video is the Nutone Broan RVK1A. The collar (part that connects the hood to the flex ducting) is included and removable, which makes a retrofit situation easier or possible. Many other vent hoods have integrated collars that are not removable. I haven't tried, but I imagine that it would be tough to get a hood and collar inserted into existing shingles. I spent most of my morning trying to find a vent hood online and in frustration went to my well stocked True Value in Ashland, WI. Fortunately they had the Broan RVK1A for $22. I opened the package to inspect it. Perfect! I got everything else I needed for this project there and will wait for a cooler day. I''m not a pro, but I think it would be best to not cut and lift your shingles when they are hot. Getting on the roof when it's hot is not only uncomfortable, but it's most damaging to your roof. Also, you will need a 5" hole saw and arbor to make the hole for this Broan hood. 5" is necessary because you need that much space to insert and turn the collar into the vent hood.

[@MeltingRubberZ28]

I think that's the vent I have. I know I need to buy a bigger hole saw so I'll have to look into that.

@@jgibs81683 I wonder the same thing. We have a bathroom that vents right into the attic.

[@bretwoods9208]

This is not the correct way to install one of these. Please don’t do this. Once the caulking fails the roof will leak.

[@leoh6742]

@@bretwoods9208 So what is the correct way?

WATER DRIPS THROUGH OUR FAN. Did exactly as Tom did. Use a panasonic 150 cfm fan, short insulated flexible pipe, and same exhaust vent. Water still drips through our vent. The problem is the corrugated pipes not allowing good air flow. Will need to change it to straight pipes to fix the issue.

[@geoffreed2450]

Thank you!! I installed two yesterday for my bath remodel. Great advice!

[@johnsee7269]

They'll never be able to replace Tommy. Hope he lives forever! He's not so bad with the Havad Yad stuff; lol! 🤓

[@kenman8728]

Simple fix for this is to use pieces of batt Insulation and stuff them into two soffits opening on either side of the bathroom vent cheap and a lot safer for DIYers not comfortable on roofs and don't forget to put a piece in the opening where the duct and vent are located

[@jeff503pdx]

Love these guys and their New England accents.

[@Vitas_1214]

Tom you are amazing, Thank you for all of your hard work!

[@Allbbrz]

Did this a few years ago ... my two upstairs bathrooms were not vented and of course, we got all foggy mirrors, condensation, etc.... the only different thing I did was to use the black tar sealant around the metal vent on the roof.

[@lancered7920]

Really helpful video. Just had to do this exact thing for a bathroom rebuild I am doing in our house. Thank you so much for sharing your knowledge!

[@leoh6742]

Same!

[@TheBalognaPony]

The hardest part of this in the Pacific Northwest is having a dry day to do this. Haven't been able to use my bathroom fan in over a month now to test out since i can't do the venting part 😂

[@mixtecop]

*excellent video, we bought a house with no vents on bathrooms, I will do exactly what you did, thank you very much sir*

[@donamills]

Thanks Tommy and TOH. I always wished you had your own show. Some of your tips, tricks and just cool ways of doing things is like watching a magic show. I see you do something, and I'm like, 🤯 then I rewind it and watch it a few more times just so I can absorb what I just witnessed. 😳That was cool!

[@Wobannon21]

Lmao! When he was putting the foil tape on, to attach the duct to the collar, there was no lettering on the foil tape. Cut the next seen, the duct and collar with lettering on the foil tape. Guess it isn't as easy as it looks 🤣

[@MADCleaningLLC]

Warren O'Bannon saw the same thing and was wondering about that

[@Jimddddd1981]

The foil tape that has the red lettering is UL rated and is code in areas that can get cold like in attics. They must have realized they where using the wrong stuff then switched to the correct tape when the camera was off. LOL.

[@07GTCalispec]

@Dragon Manifest Are you guys seriously debating the difficulty involved to apply tape?

"next seen"? :-)

Canada here. I have at any given spot in my attic, between 23-27 inches of insulation consisting of 2 layers batt and blow-in on top leaving me only 2 ft of crawl space at the peak! This changes how the install of bathroom vents looks considerably! I should have hired someone; shorter and more flexible!

[@kurant50]

Thanks for making this video. It helped a lot. I now have a new bathroom exhaust fan done right.

[@Giller9]

I love the authentic human interactions

[@billfakagrolf9815]

What happens to that little roof vent when it's covered under a foot or two of snow?

[@opentrunk]

My guess is then the hot air leaks back into the attic and causes ice dams. Especially since the connection between the duct poking out of the roof and the vent cover didn't even seem tight.

[@67jalfredo]

The hot air melt the snow and if the hold vent is sealed right, water will ran down

[@puggles4858]

Hey this is very helpful. I just bought a house and the dam fan wasn't vented at all. Straight into the attic. Awesome job. And thanks.

[@jaciuro]

Great information - comprehensive. It applies to my roof dryer vent install - this answers my questions about properly working around the shingles.

[@mikesmith1353]

Not really for your dryer take off the metal grate

[@j.mccarthy3008]

Interesting!!! I believe the flippers, who worked on the house we bought, vented one bathroom fan into the attic. They replaced the entire roof I’m told. They chose not to put any soffits anywhere. There are two large gable vents at the ends of the main peak. One bathroom vents out to a wall and you can see the little flapper. I cannot see anywhere near the other bathroom (or else where) where another flapper exists. Have to figure something out

[@tringalij]

I need to get on this project. I have a 1989 build and all the shower vents (4 of them) just vent into the attic. In the winter the steam comes out of the ridge vent and it looks like the attic is on fire! I guess it works, since it’s been that way for 30 years, but still…

[@davejohn255]

Great vid on the Braun vents I am putting in. Get a hook blade for the exato knife Tommy, it will cut thru the shingles like butter. All three of my bathrooms have no exhaust fan. A little sick of opening windows for 28 years.....and I wish my shingles lifted up so easy, mine were baked on for 10 years.

[@bradleyvollick754]

When you install a vent in the roof like that, where will the moisture go if there's a foot of snow on the roof?

[@claytonneal5097]

The warm air will make a path/opening small enough for air to escape.

[@Shakpickleball]

Open your window on snow day

What insulation blanket should I use on an American standard gas water heater?😊😊😊
