How To Install Baffle Rafter Vents (Phillips Vision: Episode - 66)

[@halucinator1]

I'll give you a thumbs up, but you installed the vents where the higher vents are supposed to drain water down to the soffit in case of a roof leak. You did well and appreciate the time to make the video.

[@forced_youtube_handle]

I see your point, but wouldn't you want to know there's an issue immediately, rather than send any water away and drain further away from the source? Even the manufacturers suggest installing bottom up. This sort of reminds me of spray foam installs under a roof. A small leak goes unnoticed because the water diffuses rather than drips. It also becomes difficult to identify the exact location of the leak.

[@jlpease995]

thanks for the video... better to start at top so your overlaps catch any moisture that gets through your ridge vent or condensation and lets it drain out your soffit vents

[@angelinef.3637]

Glad I found this video! You are saving us a heck or a ton of work and expenses with this tutorial. Thank you!

[@butanezx6r636]

My 1.5 story house only had 2 roof end vents when I bought it. I’ve added soffit vents, roof vents, and this video has helped me with the installation of these ducts as well. Thanks for this video!

[@PhillipsVision]

You’re welcome, glad it helped 👍

[@rookietherapist301]

Thank you for the detailed and slow explanation! This is my first time and this is very easy to understand. Nice work!

Thanks 😊 this is my first time doing this. Ready to go now 👍

[@georgeleone9829]

Condensation and water stains mold always an issue in roofs so having layers drain correctly is very important just like how roof shingles work except singles facing the inside of the roof

[@elviraconstantino3215]

Thanks for the video cause now I understand what is a baffle. I asked and employee of ADO insulation whats the difference between vent and baffle and the answer is "it the same it just how people use the term".

[@PhillipsVision]

That’s a wrong answer..lol

[@danshiel2632]

Good video I had mold start in my garage when up is brush went up antiotic and the guy had the vent covered with insulation so I took it out good idea

[@danshiel2632]

Over the garage

[@PhillipsVision]

With the air flow obstructed, moisture will get trapped in there

[@danshiel2632]

Sorry for the spelling what I meant to say was I had mold start on the drywall in front of the garage door Went up in the rafters And the builder put insulation over the softs so I removed it

[@Sp8341]

Wow what an awesome video. can I put plastic on top of the insulation

[@PhillipsVision]

Yes, some builders do that

[@j.darrel517]

This is a huge help. Thank you for posting

[@antjobert]

Great video!! Thank you so much.

[@MrTriple3]

Thanks for an excellent video. I need to install insulation baffles in an attic with a very shallow angle (pitch?) There will be no dry wall or living space there. I just wish to avoid covering the eave vents with the new insulation that will be blown in. There is no ridge vent on this old house, just box vents near the ridge. I think just one baffle panel (4ft.+/-) leading to each eave vent will do the job. Correct?

[@PhillipsVision]

Should be fine as long as the air flow goes from the eaves vent to the box vent.

[@danielmaslivar7071]

Great video! Would you also install radiant barrier underneath?? Like over joist.

[@PhillipsVision]

I don’t, just baffle and insulation. If you live in a hot climate the radiant barrier might help.

[@tiffanywilliams7700]

Awesome video! Question…if I’m only applying insulation to a portion I the roof (not as far down as eves vents and not as high as the roof), can I just put the baffles on the areas that are getting insulation but extending them just beyond the insulation

[@PhillipsVision]

Yes. As long as you keep ventilation where the insulation is

[@tiffanywilliams7700]

@@PhillipsVision wow. Thank you for the swift response! You rock!

[@antjobert]

Thanks for already asking this, Tiffany. I had the same question!

[@melm8808]

If dry walking to the top of the cathedral, baffling to top would be similar to the bottom where you started off?

[@PhillipsVision]

Yes, the baffle will need to provide a clear air flow path ft the eaves vents to the ridge vent

[@melm8808]

Thank you for your quick reply, Sir. Thank you for your videos.

[@laceygaldamez3521]

Seriously awesome tutorial! Question with a lean to roof that attaches to another lean to roof with no ridge vents how can I make this work?

[@LS-vu9de]

I am thinking about underlapping for water flow but putting a bead of caulk or window foam in the overlap to prevent air leak. Am I overdoing it?

[@rizhiy1]

Did you staple the bottom of the baffle? Or left it loose?

[@PhillipsVision]

@@rizhiy1 the bottom where it tucks down near the eaves vents I left loose against the beam

[@georgeleone9829]

You overlapped each section should it not be underlapped ..so new section is under the previous one ... This is so any water or condensation will drip from tray to tray out the soffit vents and not wet the insulation causing mold and ceiling stains ???

[@PhillipsVision]

It’s overlapped so the air flow and moisture flow up to the roof vent.

[@GM23XO]

Best insulation for attic? It has foam about 6-8 inches but noticed my home gets cold right after turning heater off or at night/morning. My crawlspace doesn’t have any insulation either ughhh :/

[@PhillipsVision]

R38 or R49 is best for attics

[@josephbrown2832]

can u please tell me how to install a baffle in an attic around a roof vent from a bathroom below

[@milkywayandbeyond]

If you weren't finishing off the attic (ie, the whole space was to remain unfinished), how high should the rafter vents go up?

[@PhillipsVision]

Above the horizontal beams, high enough to go above any insulation above the ceiling

[@jont718]

Very informative video! Can you tell me what size staples do you use? I just got roof installed and they use 1/2" thick plywood

[@everett8114]

I stapled mine to rafters . It has a little sag in the middle

@@PhillipsVision hell yeah, this is the exact question i came to ask.

[@jonathanvelazquez4876]

Hi, but you want the hot air to move up the baffle and exit through the roof vent so you can keep the temp in your attic low. So Q1, why not go all the way up with the baffle. and Q2. why not install insulation on top of the installed baffle so the temp in the attic is low hence, heat or cold air will not escape?

[@dominicporta6127]

I see you added multiple baffles. Should I just go ahead and use 1 or 2 since I won’t be finishing my attic and the goal is for adding more insulation? Let me know!

[@PhillipsVision]

You need to install enough baffle to provide air flow from the eaves vent to the ridge vent, or open area above the ceiling

[@JoseGomez-zg3tm]

So rafters are used were areas snow ???

[@jasonteed3734]

Thanks for the video. I am working on an older house which has 2x6s for the rafters. I am trying to minimize air clearance to the greatest extent possible. What is the air vent clearance on this specific product?

[@Dano597]

I have similar looking baffles with 1.5” clearance

[@catholic3dod790]

We need to test the air flow with the gray smoke. 🤔

[@melm8808]

How to baffle hip joints? Please 🙏🏼

[@panteradon]

Do you need baffles if you have no ridge vent? In the event that I do need them should they run to the peak of the roof?

[@PhillipsVision]

@@panteradon are you insulating all the way to the top like a cathedral ceiling ?

[@panteradon]

@@PhillipsVision yes. It is a garage roof but I want the space above the rafters to be storage. The 4 sides meet at the top in a peak. Like a teepee

[@PhillipsVision]

@@panteradon I would still use baffle to allow moisture not to get trapped against the wood ceiling

[@RockOfAgesCFM]

I don’t understand why you would do that all the way up the roof .. are you spraying insulation on the underside of the plywood?

[@RockOfAgesCFM]

Never mind, you answered my question

[@RVBadlands2015]

Do you tape the over lap. Do you then put batts, and can you then put RMax ridge foam then gypsum rock. I have a cathedral ceiling, with metal roof 4:12 pitch. Judy

[@DamnGoodReviews]

So insallation can be placed right on teh baffle vents and then dry wall? Air will flow between baffle vent and wood?

[@13634landing]

Thanks for posting. I am retrofitting our attic that is a 12/12 pitch. Poor insulation with no airflow from the eve vents due to insulation and lack of air channel. I am hoping I can correct this issue with the product you are using. I am planning at starting at the vent, like you and then proceed up the roof plane past the second story and into the attic. Cheers

[@PhillipsVision]

Hope you’re able to fix it

[@joshuasinnis8545]

Are you saying you are connecting vents level with the ceiling of your first floor via the slopped ceiling and going all the way to your attic? It's a good idea for slopped ceilings.

[@lorenbrainard9117]

Once you put the drywall up on the ceiling portion, how are you insulating that portion? Blow in? Paper backed (I assume paper side down)?

[@PhillipsVision]

I’m going to lay insulation as I mount each sheet of drywall. I’m also going to have an access panel.

[@lorenbrainard9117]

@@PhillipsVision Thanks. Great video. Exact same scenario for me so this was very helpful.

[@markpcolinsky6216]

is it safe to staple into the roofing boards? I know shingles are nailed in from outside in. I just don't know if stapling nails going from inside to outside would cause water leakage.

[@PhillipsVision]

Roof plywood is between 1/2” to 5/8”. I’m not using staples long enough to go through the baffle and the plywood completely

[@alsmith1775]

Hello, do you think 4 ft baffle from the edge vents along the house is enough, then follow the rest with reflective barrier close to the top like you finished? I live in the charleston sc area, it is humid AF outside and inside the attic is hot usually 90-100+ in the summer. House has no baffles just vent ridge at top like yours and side edge vents like on this video. Any help is appreciated

[@PhillipsVision]

If you’re going to seal up the rafters you want to run baffle all the way from ridge to eaves vents to keep air flow

[@dr.matthewhertert310]

do you have to "shave down" the insulation where the vent changes angle to meet the sill? seems otherwise the batting would force the vent up towards the OSB and defeat the whole purpose...

[@PhillipsVision]

No, just tuck it in to meet the end of the baffle

[@skilo81]

Do I need to go all the way up to the ridge vent?

[@PhillipsVision]

Only if your insulation is going that high.

[@everett8114]

What size staples did you use

[@doriswallace2618]

This video helped me so much. So I'm hoping you can help me with my project. I just purchased a 12x12 shed that I want to insulate so I can be in there everyday and possibly sleep in some nights. I was told my best option was to get spray foam insulation for the ceiling, but it's very expensive. Watching this video helped me understand the importance of ventilation and I want to do it right. It has I guess what you call a cathedral ceiling and I want to keep it open for the extra space. I have a metal roof that has a ridge vent on it but it's not screened to keep bugs and other stuff out. The ceiling is made of 2x4 rafters. So it makes it hard to put the right amount of r value for insulation. What do you suggest I do?

[@PhillipsVision]

Since your beams are 2x4 you’ll probably need a thinner insulation, but as a result you’re sacrificing insulating material.

[@doriswallace2618]

I could probably add some 2x6s. If I insulate just like you did in this video, will I need to have soffit vents below the baffles in each rafter? And will my ridge vent be suitable for what I am doing? I will be adding a mesh to ridge vent or buy new one so bugs and other things can't get in.

[@PhillipsVision]

@@doriswallace2618 for baffle use you need soffit and ridge vents so the air can flow through

[@job38four10]

But my rafters are a full 2x8" at 24"oc, so I shouldn't need baffles if I use 6" insulation........

Always leave the nails alone - don’t cut them, don’t push them back, don’t bend them. If necessary, poke a hole in the baffle to let the roofing nail pass through.

[@philmarsh3859]

So do you have to pick staples that are shorter than the thickness of the roof sheathing? If the staples are too long, they'll puncture the ice and water shield beneath the shingles or the shingles themselves causing leaks. Not a word about this.

[@kevinsheridan4601]

Self evident

[@johndill6594]

My rule of thumb is pick staples that are half the sheathing thickness. If you have 1/2” osb, pick 1/4” staples. 3/4” plywood would get 3/8” staples.

[@johntoups6338]

Do attic baffles block any radiant heat if you run them between your rafters, up towards the roof ridge vent? I have a bunch of extra baffles, so i was going to use them up in that manner if they blocked some of the roofs radiant heat.

[@rebeccajenkins3347]

Super helpful!! One question…I have two “non-standard” sections (one 7-1/2” W and the other 10” W). I bought the exact 14” W baffles at Home Depot. Do I just cut them down? Will that impact air flow? Thanks so much!!

How to you insulate around or over roof vents that are cut into the roof already?

That is the wrong baffle for retrofit. That type is meant for new installations before the sheating goes on to the roof. Please don't use these and risk penetrating your roofing layer with staples. They make ones that fit between the studs and have flaps that come into the space and allow you to staple them to the rafters instead.

Why not use very short 1/4" staples that can't possibly pass through the sheathing?

@@Dave-co1cv The other problem you run into is that these will sit flat 1" on each side next to the rafters. Cutting off any airflow down that strip and only allowing air where the middle bows out.
