This Old House general contractor Tom Silva shows how to properly install a roof-mounted bath-fan vent. (See below for a shopping list and tools.)
SUBSCRIBE to This Old House: bit.ly/SubscribeThisOldHouse
Tom helped a homeowner with a bathroom fan that was venting moist air into his attic. The fan's vent was installed on the underside of a roof soffit, causing moist air to get sucked up into the attic, which was leading to mold and mildew problems. To correct the situation, Tom moved the vent onto the roof, being careful to flash it properly so there would be no leaks.

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.

This fan works very well. ru-vid.comUgkx7yWIKcrbA9KMHkGSfcgxW2lsjHT6B8Sh I replaced my old fan as our radon levels began to spike. When I remove the old fan water poured out of the fan. Must have entered in through the out spout. Replaced with this unit and levels dropped a bit but still over 4.0.Did some more digging and found that we had a small hole under our waste pipe that was allowing some water and radon in.Patched the hole and the levels dropped almost overnight.I really would recommend the radon sensor. It gives real time readings. Without it we would have never known that we had this issue.

@DougCeleste Месяц назад

@jimturner4937 27 дней назад

@@DougCeleste When I lived in Fort Dodge Iowa the radon was 8.0. I had to put in a mitigation system to get it lower. I installed a sub floor system which goes down to the gavel and applies vacuum under the basement floor venting out through the attic. The levels were brought down to 0.8. Note, some of the radon infiltration comes through the sump pump hole. First thing to do is seal that up nicely and attach a 2 inch pvc pipe from the the top and vent it outside.

@j_dane9519 2 года назад

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 2 года назад

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 2 года назад

you the real MVP, thank you for these notes!

@NoName-sn1le 2 года назад

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 2 года назад

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 Год назад

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,

@@blakewhite3131 Thanks for your reply! Your comments reminded me of having the courage to climb the Sydney Harbour Bridge in 2002 on that tour with others on my final full day in Australia. I have to admit that I was feeling TERRIFIED at the thought of doing this climb but since we wore a special uniform with safety gear connecting us to a rail while we did the climb to the top and then back down, I felt a bit more at ease. 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. But that is ok since I will always have the VERY fond memory to cherish of that afternoon in Sydney, Australia. Cheers from New Mexico USA! 😎

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.

@woohunter1 6 лет назад

Something that is just as important as venting to the outside, most people don't let their fans run long enough to "dry out the duct", should also install a countdown timer as well.

@nightfangs2910 4 года назад

True ,and I would add when putting the ceiling fan in to buy one that has double the output needed for your bathroom ( as it ages will still be efficient) and one that is rated whisper quiet

@alexmoreland7938 4 года назад

night fangs I prefer a noisier fan to cover the sounds made inside the bathroom.

@Milosz_Ostrow 4 года назад

One could use a humidistat instead that would keep the fan running as long as the humidity in the bathroom exceeds a certain value.

@renedelafuente123 9 лет назад

It's nice to have that much space in the attic to have plenty of room to work in. My attic is so small that I can barely fit by crawling in there. I also need to add vents to my two bathrooms.

@ericolson5314 8 лет назад

I feel you there. I just completed one of mine. Had to put a skinny piece of plywood down and perform all the work lying on my back. I doubt the duct was even an 18" run! One down, one to go. Good news is the other one is easier to get to.

@perproject06 8 лет назад

+Eric Olson We're on the same boat Eric. Did you follow the steps provided in the video or did you do it a different way, using different materials? A roofer here in FL wants to charge me $600 per vent and I have two to do. That's freagin highway robbery if you ask me.

@ericolson5314 8 лет назад

+Van S. I pretty much followed it exactly if I recall. The caulk I used was specific for roofing (it's black, not clear). Oh, one other difference was that my cap had the collar built in and was therefore very tricky to slide under the shingles. Ended up pulling up shingles a bit more than preferred, but I was very generous with the caulk. Anyway, no leaks so far after many heavy storms.

@perproject06 8 лет назад

+Eric Olson Cool. Where did you purchase the louver from? I've read online that some are good and some are bad. The bad ones get a backdraft from heavy wind and rain. And some rusts away very quickly due to poor materials used and craftsmanship. Thanks in advance. Links would help as well... Cheers.

Wish I had done this 12 years ago when we bought our place and discovered it had been vented into the soffit like this one. I just had a Mould remediation company come to remove / treat my attic. Cost me just under $3,000.00 to have that work done. Builders who take shortcuts cost the home owner LOTS of money and aggravation. A simple proper roof vent would cost a tiny fraction of what I had to pay.

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.

Very professional work ! ...Meanwhile in snowy Canada we usually install the bathroom fan exhaust in the soffit because during the winter you would have to clear the snow off that roof vent every snowfall and sometimes that would be several times a day..... we block like 16 inches of soffit each side of the vent to make sure that the moist warm air doesn't go back in the attic.

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

@stopfollowingme2391 6 лет назад

You don't really have much choice as far as horizontal position since it needs to be between the rafters. There is enough flashing to handle the worst-case alignment. Tommy didn't go into it but there is room to optimize vertically so that you get a clean install starting at the end of a row of shingles. Notice how he trimmed the shingles to fit the vent hood before drilling the hole into the roof. That hole doesn't have to be centered on the original nail.

@johnbravo2301 9 лет назад

Very informative in regard to improper initial installation and proper installation . However, they explained the problem of installing vent in a vented soffit thus causing vapor to enter the vented soffit ,therefore causing mold growth on the roof sheathing etc. Nothing was mentioned on what they recommend for the removal of the mold that already started to grow. Stopping the vapor penetration into the vented soffit doesn't stop the mold that already started to grow.

@johnbravo2301 9 лет назад

Mike Oxlong Thanks for the information however .. .......................I completely disagree, .. In truth bleach, clorox(NAClO) will not kill mold ( in ) porous or wood surfaces.. the molecules of bleach or clorox are not small enough to penetrate porous surfaces and kill the mold and thus will regrow..When using the shop vac as described by scrubbing should be accompanied by a hepa filter not just a "good shop filter",all you do with a "good shop filter" is spread through a general purpose filter and disperse any live mold molecules through the air discharge to other areas for regrowth .You have to use a Hepa filter due to molecular size of the mold. The size of Hydrogen peroxide molecules better penetrate porous or wood surfaces. You would be better using hydrogen peroxide H2O2 in a concentration greater the 3% .With Hydrogen peroxide N95 mask should be used. To add: depending on the area of confinement and amount of mold you are treating with aerosolized Hydrogen peroxide you need either goggles or a full face filtered mask.. and I caution anyone who uses contact lenses while working with aerosolized H2O2 ,you may end up with irritated/burned corneas, if possible work without your contact lenses or full face filtered air mask. This information can be verified by trusted sources , internet, mold abatement services.
