Installing Soffit Vents in My House for Attic Ventilation

[@brettbarager9101]

I have worked with 5 different contractors who each knew the "right" way to do something . . . Now I have 5 "right" ways to do the same job (6 if you count my right way!). Good vid

[@TheHavocdog]

18:51 I bought a house with only 8 inches of insulation In the ceiling. Also only 2 soffit vents and no venting in the roof. The air conditioner ran continuously from 10 am to 8 pm in the summer. The house temperatures would slowly increase to 79 degrees by 5:30 pm. My electric bills were high. I installed only 4 more soffit vents. But I installed 4 roof vents as well. I then added 4 inches of extra batts of insulation over the existing insulation. I should have added more insulation, but what I did add was very effective. I cut my electric bill for air conditioning by 30%. More importantly, I could now keep the living area of the house at set point at 73 degrees. The air conditioner now would cycle on and off versus running continuously. In the winter my heating bill was reduced by 25%. A little "do it yourself" work really paid off!

Many of the materials that you are using were not around when my Dad built this house 60+ yrs ago. Your videos are a help as we consider the repairs and help me know what to research for our codes, etc.

Very thorough. Intake & exhausting is equalized. Looks like the best way any roofing specialist would do it.

[@jacobjaeger5492]

Really enjoyed this approachable tutorial and your simplified explanations. Big plus is you talking to yourself while you're doing the install - absolutely hilarious. I was just watching to watch at that point.

You can conect pvc piping to the vent cover. Make the pipe length to be one foot above the blown in insulation. Anchor the pipe with plumber;s ribbion

[@shoyrushoyru]

People's opinions about venting attics and roofs are all over the place. Probably a year to a year-and-a-half ago I spent some days researching what the right way attic venting should be done is, and the only thing I really walked away with is that every "professional" says the opposite of what the last one says. It's really irritating because they all treat it like it's something obvious and that you'll start the apocalypse if you do it wrong but then they all say opposite things from each other.

[@johnattancortes8581]

this is very true, some people seal their attics others say attics should breath, the contradictions are endless

[@27photogger]

💯 %

[@myobmyob2215]

And then you have code and inspectors opinions too. Really? Not knocking a whole bunch of massive exhaust holes in a roof unless it's going to be approved at some point, not because some guy said so.

[@bluefidle]

And then the inspectors don't really check things or or agree.@@myobmyob2215

[@55robinwood]

Well in the south we have to vent ours big time. Otherwise the attic will act like a heater AGAINST THE AIR CONDITIONING.

[@leslietinyhousebuilderwann3851]

We live in Texas. We recently moved into a house without insulation. Yep that’s true. Crazy I know. I’m guessing that the vents are extremely important here.

[@heyitsbroski]

A house in Texas without insulation? Crazy. I live in Texas and insulation is a must.

[@Darryl603]

You could drill holes through the horizontal blocking if you feel you need more air flow. Thanks, Matt

[@skootles1]

Thanks for sharing. This is exactly what I was looking for. Remodel of a 1940 house, tons of mold forced a whole house remodel. The cause was mold and inadequate air flow and blocked by insulation soffit attic venting. Great video

[@milliewilson9614]

I enjoy watching your videos. Mainly because you don't claim to know it all and your way is the only way. You do you!! Your remodel is so entertaining. Keep making these videos. I can hardly wait to see it finished.

[@timothystevenhoward]

I did the plastic trays above my garage on what little soffit I have. also added a attic vent on the gable end. made my garage 100% more bearable. It would get well over 100deg in there in the summer.

[@arthendrickson4860]

+4000°! 😂 Great job! Thanks for all the details and showing (e.g., through the soffit holes and inside) what’s going on.

[@lynnraarup5258]

Such an excellent explanation and great process for attic venting. In the process of venting you have also eliminated the need for repeatedly painting your soffit as there will be no more condensation dripping from the underside of your roof. And no more icicles. Thank you!

[@graphicwombat]

Good stuff! Our ww2 era 1 & 1/2 story home had absolutely no insulation in it. So when I started to gut and refinish the upstairs I put insulation in everywhere I could. In addition to not being insulated it also does not have a soffit or ridge vent. BUT it does have 2 gable vents. For the sloped ceilings above the knee walls I’m using 1.5” thick foam core insulation board. Since our rafters are only 2x4s I couldn’t use rafter rents and traditional insulation. Instead I cut the foam core boards so they over hung just past the knee wall and just past the collar beams and wedged them (between the rafters) flush against where the drywall goes. This leaves a gap between the insulation and roof decking for ventilation from the crawl spaces to above the true ceiling. Now that I know how to add soffits, it will help cool the crawls spaces behind the knee walls in addition to the true ceilings above the rooms where the gable vents are. For good measure I’m throwing a gable mount fan on the rear gable. 👍🏽

[@stefanpia5419]

Love your channel! It’s possible your gable vents are interfering with the intake at the soffit and the exhaust at the ridge vent. You might take some temperature readings in the attic with gables sealed (cardboard/plastic) and compare with gables opened. “They” say not to combine soffit/ridge vent with gable vents. Might be interesting to see what a thermometer says.

[@MikeM-bn2ij]

I did it like you said and put a temperature humidity sensor up there. Open gables with ridge and soffit vents was 140+ in summer, 40+ degrees over ambient in winter, spring and fall. Plus during heavy rain the ridge would intake water. Closed off the gables and now it's Max 20 degrees over ambient plus no rain.

[@ryanlaporte8224]

My experience was my gable vents screwed up the air flow. I had to cover them to keep using the soffit vents with the ridge vent

[@MikeM-bn2ij]

Same here 👍

[@ncooty]

@9:22: Use the clutch, variable-power trigger, torque adjustment, or side handle.

[@derksgarage]

I recently had my attic spray foamed with 4" of closed cell, literally the best thing I did for my house. I'm of the mindset that an "air" sealed home is a better functioning home. It eliminates all variables, but most definitely at a $$ cost.

[@lillianahill7942]

What do you mean by sealed? I’m curious as I’m doing a lot of home repairs myself

[@derksgarage]

@@lillianahill7942 I meant to say "air sealed". This involves encapsulating the house so that the conditioned air has no way of exiting the home. Matt Risinger and Build Show Network talk about this a lot and it's known to be one of the modern building science principles in new construction.

[@rodolfoamador940]

Just a caution when you seal with spray foam the attic its harder to sell your home, because the mortgage companies cant see your Rafters and joist etc so they don’t know if its rotted so they might not finance the deal just a fyi

[@DanielinLaTuna]

@@derksgarage, I hope you also added a dehumidifier system like Matt Risinger did on his build. Otherwise you WILL have a mold problem at the ridge, sooner than later. The reason is that even though your attic is now within the conditioned space, moist warm air is still rising and the moisture will condense on the wood products (probably OSB? maybe plywood, or unlikely 1X planks) that make up your roof deck.

[@rjt135]

I've been thinking about re-doing my attic insulation now that I finished the rim joist. This definitely got those wheels turning again.

[@jamesscheuer8367]

Excellent camera work and clear explanation. Well done!

[@judmcfeters9054]

The “they” who say a well vented attic is the same temp as the outside air are only considering thermal convection (air movement), while ignoring thermal radiation (infrared light penetration through the roof) and thermal conduction (bridging of hot or cold through the mass of the roof materials).

[@SpringRubber]

Very nice video. I'm located in Virginia and have a 1960s rambler-style house that has similar venting: a ridge vent, gable vents and evenly-spaced round soffit vents like you installed. For what's it worth, when I had the roof replaced a couple years ago about 85% of the plywood sheathing needed to be replaced which made for a big expense and a bunch of extra labor. I've been in my attic a lot over the past few years to re-insulate, air-seal and re-wire some circuits and I'm thinking that my 2 gable vents have been defeating the purpose of the soffit vents. I'll probably experiment and block off one or both gable vents and see how that affects attic temp this Summer. btw -- if anyone is looking for a detailed, hands-on book on insulation methods and the concepts, "Insulate and Weatherize" by Bruce Harley has greatly helped me.

[@nodramamama3438]

I appreciate you addressing all the comments before they happen but those people who already know these things so they're not your target audience. Ignore. The airflow was epic. Love from Canada 🇨🇦

[@DIYHomeRevival]

Good stuff man, thanks for uploading this video. It's going to help me out a lot. My mobile home has overhangs but the ventilation is non existent. I'll have to drill some holes and put up the rafter vents also, this gives me a good point of view of what I'll have to do. Thanks again!

Great tip about the cordless drill

[@Rachelmarie413]

I’ve got a cape cod style house. We have an attic that we can’t access but we also have a crawl space that runs across the from of the house on the second floor. We just ventured in there and found lots of mold all over the ceiling 😩 we have soffits but they clearly aren’t doing the trick. We’re thinking of adding gabbles on each size of the house because I don’t know if we can afford to add the ridge vent but i think it’s gonna look weird. The struggle is real!

[@TheFixerHomeRepair]

I’m sorry to hear that. 😞. You should get some quotes from some roofing companies. Ridge vents are not a ton of work, you might be surprised with the price. Or DIY? Take the caps off, cut a hole, add ridge vents, add the caps back on. I know it is easier said than done but it is something to think about. Good luck and I wish you the best!

My house doesn’t have fascia end board or soffits. It’s just rafters with bird block in between. I was wondering if I can add vents onto the bird blocks in between each rafter and it will function the same as the soffit vents? I want to do this because I want to remove my gable vents so I can insulate and drywall the attic. But I still want to make sure it’s vented. Yes, I will add baffles and there is already a ridge vent in place.

I've never been in an attic that is only as hot as the outside on a sunny summer day. Always seems to be about 50 degrees warmer. Even in new construction with "modern" insulating standards, whatever that may be.

[@shoyrushoyru]

"modern" insulating standards seems to be having any insulation at all, cause some of those old houses have completely or partially uninsulated ceilings and then wonder why they cant keep cool or hot in the appropriate seasons

[@Guillotines_For_Globalists]

@@shoyrushoyru Old homes generally had no insulation in the walls period. Pre-1960 or pre-1950 certainly. Especially the double layer brick homes, with the perpendicular bricks that connected both brick layers together.

HI, Mr fixer, I am really learning from every video you do, thank you for that, I as you know am working on my old farm house after my broken back has healed somewhat, I was shocked to find pin holes in gas lines around my home and had to have them all replaced, the gas company filled the pin holes temporarily while I awaited the full repair. I don't know if you have ever checked your gas lines in your home or not, after what happened to me I would suggest befor you close up your walls you have the gas company come and check your lines.... every line had small pin holes so ya hot water tank leads, furnace leads and under the ground just where it entered my home. Just a heads up.

Redoing the attic insulation is on my list of need to do in my 50 year old house. Especially once we saw damage from ice dams last winter. On the other hand, I've seen some houses around me that have covered their soffit screens with insulation and wonder why they're having issues. More isn't always better.

This came at the perfect time. I'm getting a Tuff Shed studio pro (lean-to/single pitch) built soon. I'll be using it as an office and ceiling area will be full of insulation, no attic space. It'll be climate controlled with a mini split and completely finished with drywall. I've been told to add soffit vents, but also told to not add them because no need due to not having an attic. can you please share you recommendation? I live in SC. Thanks for your videos!

[@dereckh]

@@enamoredreviewsyeah sure did. both sides 2" round vents between each set of rafters. and since my insulation goes up to the roof i bought these plastic tray things to put under so that airflow can easily travel out the vents

[@riffdex]

So the baffles need to go up the entire length of the rafters to the ridge vent? Some forums they’re telling me to just install baffles at the soffit to prevent insulation from blocking air flow, then the remainder of the rafter lengths is an air pocket that is left below the insulation to facilitate air flow to the ridge vent. So I need the baffles over the entire length?

[@miked451]

You should not need them the entire length, just to prevent the insulation from blocking the path near the soffits.

[@riffdex]

@@miked451 What if I want to add batt insulation to the rafter bays and ultimately finish the attic area? Should I install baffles up the entire length so I can place the batt insulation over and still leave an air gap to the ridge?

[@madman432000]

I thought those vents have little friction tabs to hold them in. You really only need about 2 foot of that vent channel stuff between the rafters, after that the insulation shouldn't block the airflow. The last person that painted that soffit didn't prep very good did they?

[@jsaysyay]

always nice combo of informative & fun in your videos, really enjoy it. i do wonder, you've done so much with insulation and ventilation, i can scarcely imagine how different it's been over the years in terms of cooling in summer and heating in winter

[@crazysquirrel9425]

Impossible for me to install rafter vents unless I rip out ceilings and tops of walls. Took me 4 hours to make a template and cut out for ONE soffit vent. Reason: had to do it 18 feet in the air on a ladder and saw through one inch of hard wood (house was well built back in the day). My roof joists are 24" roughly on center so that too made it a challenge to get the vent centered. I used a rectangle one, not a round one. I have the vent and box vent nearly equal too. Not a lot of change in crawl space air temperature (attic type crawl space). But even 5 degrees is better than nothing.

[@herbstava]

Great video! Been looking to do the same thing myself. My question is what if my soffit has a pvc cover over the sheathing?

[@JalonBerrios]

Equal one way in equal one way out is the best I can say overkill will cause mixed airflow and not exhaust

[@MikeM-bn2ij]

Have you got water in the attic during heavy rain? Usually happens when you have soffit, gable and ridge vents. Personal experience here had to block my gables no problem since just fyi so other's don't have the same problem

[@969Garage]

I have a 1300 square foot ranch in southern nh that suffers from poor attic ventilation. Is there a formula to try and figure out how far apart the holes need to be? And how big of holes i should drill? Or am i over thinking tbis ? I found a few sofet holes under vynal siding but they are only 1 inch holes and they are like 10 feet apart or more

[@ericshoesmith9882]

Do you think adding holes in the wood for soffit vents is sufficient ? Or would some instances require taking out the wood blocking air flow and adding aluminum perforated soffit?

[@danceforpeace]

[@hubertwhitlock9968]

You don't want a ridge vent and a gable vent because the air will take the least path of resistance and it'll come in the gable and go out the top you want your soffit to come in and go out the top I would either do that and block your gables or not put in a ridge vent

[@gregmize01]

Nice job as always!👍👍👍👍

[@MaMa-qh4dy]

Good job, but you need to block off those two gable vents. Otherwise, the you will be short-circuiting proper ventilation flow which should go from the eaves and all the way up to the ridge vent.

[@shoyrushoyru]

what happens if you short-circuit proper ventilation? i keep seeing people saying to not combine multiple types of attic ventilation but no one ever says what actually happens if you do.

[@MaMa-qh4dy]

@@shoyrushoyru For instance, if you have a roof exhaust fan, gable vents, and soffit vents, the power of the fan will pull air in from the closest intake (gable vents) and not pull in sufficient air from the soffit vents. This will cause inadequate amount of cooler air flowing from the soffit vents to the fan. If using ridge vent with gable vents and soffit vents, the same poor venting will occur. Best is passive ventilation using ridge vent and soffit vents.

Can anyone help me with the right way to vent the attic, the old roof had no ridge vent and gable vent on each side. The roof was replaced 8 years ago and the roofer installed a ridge vent and no soffit vents. He said the gable vents are good enough. My understanding is when you do ridge vent you need soffit vents and should close the gable vents. Is the way he did it ok? Without the soffit vents will it cause any issues.
