Hey! I would be interested in using this video as an education tool for my small roofing company. Do you mind me including it as an email link to our shingle customers?
The roof pitch acts like the sail on a ship, it picks up the wind and amplify the wind to the peak. This wind can effect ridge vent exhaust performance. Box vents being scattered around the roof eliminate this wind problem. Leaking is a different issue. Wind blows snow and rain up the attic and into vents, box, ridge or turbine. Snow proof vents are needed.
Thanks for your service, now, my biggest complaint with my ridge vents is everything from bugs to leaves get inside my attic. They need to improve them.
Great to see a fellow veteran doing well. Can you do a follow up by showing the empirical data on how much air volume actually moves through the attic by each vent type? I'm a big fan of the ridge vents, so I'm hoping I didn't make a mistake.
It’s about time for you to go and clean your ridge vents. Oh yeah, nobody talks about that. After about 2-3 years, all of those tiny little vents become plugged up with all dust and fiberglass particles that accumulate in every single attic. Thus reducing even more air flow. It’s not a theory but a fact. Now imagine after 10-15 years of being up there
Hey Brad, glad to hear it! We will be making a lot of videos going forward both helping roofing salesmen, roofing contractors, and we do some videos for homeowners from time to time. If you ever have a recommendation for a video, please let me know. Thanks for the subscription and good luck on those last 5 years!
What are your thought for garages? My garage does not have an “attic”. My ceiling goes to the roof. Should I install a ridge vent to allow heat to escape the garage or no ventilation at all? I’ve gathered from this video that ridge vent is superior to box vents, so I’ll either use ridge vent or nothing. I want your advice. Thanks.
i understand his four valid points, but at the end of the day my two attic fans will cool my attic better while the ridge vents couldnt get my attic below 120 degrees. therefore, don’t recommend ridge vents
It has been reported that active powered ventilation in an attic (e.g. some sort of ventilation fan) actually draws air up through electrical wall outlets and light switches, through the framed wall sole and top plates, and even around A/C duct vents, so basically you’d be cooling the house with the chilled air from inside your home. It’s no wonder the attic is cooler, right?
Don't get me wrong. I am a fan of ridge vents on your house but having worked pest control for a number of years now, they do not eliminate critters. Squirrels will happily chew straight through those.
Ridge vents are not a very common place for squirrels to get in through. I wouldn't stress a whole lot about it. Gable vents or rotten eaves are far more likely. The couple of times. Times I have seen squirrels get in through that. The only way we've found to keep them out is to put a steel hardware cloth over top of the ridge vent. The trick is attaching it in a way where you don't cause a leak.
Go to Lowe's or home Depot and get quarter inch hardware cloth. It's usually out in the garden center. Cut it into an 18 or 20-in wide strip and roll it down the length of the ridge vent covering the whole ridge vent with a couple inches of overhang on either side and use some self-tapping screws with washers on them to secure it to the vertical pieces of the ridge vent about every 12 in. Don't try to put the hardware cloth up from inside the attic. Squirrels will still chew through the ridge vent and then through the decking and go around the screen
@@Posterharpua - After some additional research it seems like the baffles would stop the bulk of the water but I'm unconvinced it would stop issue to prevent issues.
Love your video, short but pacts with tons of info and straight to the points. You mentioned need to clean the ridge vent once a year? That seem like alot of money to cough out as average homeowner would probably not climbing to the roof(especially steep one) to do that task and thus requiring hiring out contractor.
Thank you, and no it's just "recommended" particularly if you have a lot of trees around. The system is going to work regardless, just simply something to look out for.
@@DigitalRoofingInnovations Hi: I am in Colorado which is very dried here due to high elevation. I have a hip and valley roof(or pitched roof), and my ridge length is only 13'4"(highest ridge of hip roof)( Total ridge length is 67). with 4 turtle vents used on this roof. Do you think it is worth it for me to cough out $500 or $600 to have the ridge vent put on? Will there be ridge vent put on the other ridge(the two valley one) or only one ridge vent on the main hip roof? I am having doubts that the ridge vents on the hip roof 13'4" will be significantly make a huge difference than the 4 turtle vents,
@@wkk6478 I am not sure without seeing your roof. I would trust whatever your qualified local roofing companies are telling you. Honestly, ventilation is important, but it's only one portion of the total roofing system. How the shingles are installed is a far more important piece to the puzzle.
@@DigitalRoofingInnovations some people saying the baffle design of ridge vent will eventually clogged with dust and debris and would not function well. Just worry eventually it would have to replace with new one again.
@@wkk6478 I have yet to see that done. I appreciate all the questions, but I think you are worrying way too much about the ridgevent. Again, this is just a part of the overall roofing system. I would err to the expertise of your contractor on what he wants to install on the home. Let us know if you need anything else!
Plastic ridge vents warp over time allowing gaps where mice and other critters can enter. Ridge guard can then be installed to fix that problem. Ridge vents is probably the most common place for mice to enter!
Some of the contractors who gave me a free inspection told me that ridge vent is not a good idea for my roof which is not flat or too steep. Are they right? For the ventilation work properly, do I need to install inflow vents as well? My roof only has some Soffit Vents. Appreciate your input ASAP as I'm in the process of having my roof done. Great video! Thank you.
You're welcome! Well, I am not sure why exactly they said you cannot install ridge vent. Most manufacturers recommend ridge vent for 3/12 pitch or more, which shouldn't matter if you say your roof isn't very flat. Do you have what's called a HIP Roof? We have a video about that if you're interested. Maybe it's because you don't have enough linear footage for the ridge vent. I would ask the contractor to give you a reason why not.
The issue i had with ridgid vents is the snow coveres them and since they are plastic and have some sort of mesh in them it kinda insulates and doesn't melt the snow off fast enough in a house with alot of insulation. The can vents are made of aluminum and aluminum conducts heat faster than almost any other material and that melts the snow off and allows the ventilation system to work properly. If snow melts off your roof fast due to poor insulation then this may not be a issue for that house. I will never put a ridgid vent on my house again. I added roof cans even though it has a ridgid vent.
I live in a windy area in N Nevada. Our winds primarily come up from the south and blow to the northeast. The roofline of my home is mainly east/west, so the south slope gets much of these strong winds. I'm getting a new roof installed, but am also getting conflicting advice from different contractors. Some are recommending the ridge vent, while others say they are prone to leaks due to the strong winds and the way my home faces the prevailing winds. I was originally wanting the ridge vent, but now I'm confused. ???? AAAAUUUGGGGHHHH - What to do???
Bill, if you have legit contractors in that area telling you not to do it, I would listen to them. There's nothing wrong with some good box vents. What's most important is your contractor making sure you have the proper ventilation with your intake and outtake. If it were me, I would just go with the box vents in your case.
Questions 1). What is the gap to cut in ridge for ventilation for the ridge vent model you recommend 1” each side without a ridge board? 2) if I am having a hard time getting the one you suggested what you think about Air Vent VenturiVent 1.1 in. x 14.2 in. x 48 in. Ridge Vent in Black with Nails (Sold in Carton of 10-Pieces Only) or Owens Corning VentSure 9 in. x 20 ft. Ridge Vent Rigid Roll with Weather PROtector Moisture Barrier or Owens Corning VentSure 11 in. x 20 ft. Ridge Vent Rigid Roll with Weather PROtector Moisture Barrier or? The roll out kind vs the fixed pieces? I am in sw oregon so can get snow and lots rain but also heat up 105 in summer
Great questions! Ridge vent cut out: Size should be 3.5" overall assuming there are trusses or a maximum ridge board width of 1.5" (or anything between). This will allow the air to easily flow out of the attic and through the respective ridge vent. This 3.5" equates to 1.75" off the center of the peak on each side. 2. Any hard plastic ridge vent will suffice so that brand is just fine. Good luck on the project!
It's interesting because the roof your standing on is the same pitch as our flat roof that has no tar shingles just the rubber type material. A ridge vent was cut due to only having tiny gables that do nothing. Also it's hard built with no way to add soffits. I need a better ridge vent than the foam strip that they used. I like the type you installed. I'm looking into that soon.
Steven. Thanks for the comment. I know the roof probably looks flat in the video, but this is my house and it has a 4/12 pitched roof. You likely have a 3/12 pitch or below and have what’s called a PVC rubber system. If that’s the case, a flat roof is much, much different than a pitched roof. You will not have traditional soffits and will not be able to add a ridge vent. Hope this helps!
To all of those considering ridge vent, please don’t do it. I have been doing a/c and heating for 28 years, owning my own company for 16 years, and that’s in S.E. Louisiana. I know attic’s and believe me everything about attic heat. I’ve never heard of a roofer recommending anything but ridge vents. It’s because they aren’t allowed to wire them up but mostly it’s just too easy to nail the ridge vents down and walk away. In all my years I have never seen a house with ridge vents have a decent attic temperature. They look great on computer models but in reality, doesn’t happen. Too many other factors such as soffit vents, the correct wood cut off on each side of the ridge, and enough ridge vents, all contribute to the doom. I install regular and hybrid ventilators. My shop still has two 17 year old ventilator running like a charm. The secret? 3-4 drops of oil on the top and bottom bearings and setting the temperature to 105*. When that heat builds up in your attic from ridge vents, it’s got nowhere to go but down into your home. Good luck fellas. I’m happy to see people interested in the topic. And I wasn’t trying to be rude to anyone. I apologize for that but I’m the one who is working in the attic heat
Kirk, thanks for thsi comment! I clicked on the vid here becuz I wanted to Know what kind of impact a ridgevent would have on attic temps and in turn, how it would affect ur home cooling bills..in other words, will the ridge vent lower ur utility costs by venting that hot attic heat better than conventional gable electric fans on each end of the attic? oone making these vids talks about that...ever... LOL As afr as the attic fans, they have been a major pain in my situation becuz theres always one, on the farthest end of the attic that will tend to fail , mid summer in the worst heat... so i'll have to do the attic crawl, for what seems like a 1/4 mi to that far end, brething thru a respirator so as not to inhale the insulation dust, while holding a bag of tools and a flashlite ,trying not to fall thru the sheetrock, enduring what feels like being baked in an oven heat, as I unbolt that fan to bring it into the garage to work on... fun times! mine usually sieze up and have no oiling holes to put drops in so i have to rebuild them... thats why ridgevents sounded interesting but i heard bad things about them as well..
it’s just a little 45* angle dimple and if it’s not then use a noodle type tube to get it at the top and bottom of the shaft. Then keep working it back and forth until it spins freely. Oiling it before it is installed is best but you can usually even get them to come back to life with oil 👍🏻
I was thinking of installing ridge vents till I thought it over. If a hurricane was to ever to make landfall in your area would that cause a leak. The winds will push the rain up and over the other side but since you have these installed the water could get pushed up and enter the vent causing leakage into the attic
@@DigitalRoofingInnovations I thought the angle is also another factor on whether or not the ridge vents are an option. If its steep you cant use it cause the sharp angle which would also make it harder for the rain to be pushed over.
Great video explaining this system! Thank you! My house was built in the 70's and has the mushroom or round air vents. If I want to replace these and put in the Ridge Vent system, how costly will this be? The old vents would need to be removed and the holes covered. What is your feeling on the best material for a flat roof on a porch and does this roof need to be ventilated? Thanks!
Walter, that totally depends on the ventilation. Are there any vents up there right now? If so, I would just leave what you have and wait until you needed to re-roof the building.
Just ordered a new roof, and it's coming with ridgevent. I have a problem with Pinetree needles on my roof. Looks to me like thousands of pine needles are going to get stuck in those little gaps and be next to impossible to clean out. They get in every crevice of every car on the property...after seeing this, I'm not sure it's the best solution for me. Let me add, my roof is an offset-A frame..two thirds of the roof on one side, one third on the other. Will this uneven distribution affect venting? Thank you.
I just had my roof replaced by what was supposed to be the best company in my area. I had requested the installation of ridge vents. OK, fine, that was done ... but they also replaced the box vents instead of plugging the holes! They tried to claim they saw some sort of ducting below the box vent holes and so did not plug the holes and roof over them. They further tried to claim that with dual vents, the temperature results would be even "better". I'm not believing them, will be calling their scheduler later for an explanation. Thoughts?
A box vent with ducting below suggests it's venting a specific thing/area, e.g. your dryer or maybe a bathroom. Your contractor likely did the right thing
@@bengee5996 I reviewed with the scheduler. The roof section involved is over the kitchen, and there is no space between the decking and ceiling but that needed for ductwork. He said the foreman claimed to him there was ductwork under the box vents. We reviewed the area in question and could only conclude the ducts were blind, leading nowhere, possibly installed when built for a future use that never materialized.
@@bengee5996 As I said, there is no attic. The only cavity in that whole section of the house is the gap between the roof decking and the ceiling, only deep enough to run ducting, wiring, etc. There's not even a way to visualize the space.
I live in Texas and am considering replacing my roof now. Wind turbines are popular here. I was wondering if you think they are any good. Currently there are box vents on my house. They are plastic and one seems broken. The roofer mentioned Ridge Vents today. I just want to do the right thing for my home.
Which gives better ventilation, a ridge vent or an attic fan? I have one attic fan, and I've had to replace it (or the motor) 3 times in the past 17 years, and it's a pain the a$$ to do that. I don't have a ridge vent, and I was wondering if I should get one and ditch the attic fan. My house is an L-shaped ranch with 2 peaks...one that runs front to back (40 ft.) and the other that runs from the middle of the house to one side (17 feet).
Thanks for your video, but what happens if you have a hip roof with a short crown (only 10 feet) for a large home? We had our roof vent installed in 2009 and have substantial moisture in the attic causing damage to decking plywood and drywall in upstairs bath.
John, great question. You can use ridge vent and then hip vents under your ridge cap. They look very similar to ridge vent. In your situation, you could also just use standard mushroom vents. While we like ridge vent, mushroom vents are just fine.
I live in central Missouri. hot summers, cold winters. My house was built in 2004 without ridge vents, but the roofer thats replacing my original roof recommended ridge vents. I'm skeptical because the extra cost is significant and the original roof lasted almost 20 years with builder grade architectural shingles. The new roof is impact resistant Owens Corning. Any thoughts on adding the ridge vents? The house already has large gable vents and soffit vents.
I own a 110 year-old house with a gabled roof and finished attic that is unconditioned space with several single sash windows. Original roof was slate, and never had a ridge vent or gable/soffit vents to provide air intake. Windows were opened in summer months for air flow, but kept closed in the winter months. The slate roof was replaced in the early 2000s with a 3-tab asphalt shingle material and a turbine vent installed along with modifying three windows with louvered vents to allow air flow into the attic during the summer. These louvers are then covered in the winter months. I am now facing the need for a new asphalt shingle roof and contractor is recommending a ridge vent and soffits for air intake and to secure the manufacturer's warranty. I'm questioning if this is the appropriate solution since the home has never had a ridge vent and there haven't been any known issues thus far. What is your opinion?
Thank you for your video! We are getting our roof done and they want to put back the vent caps with installing a ridge vent as well. Us this a good idea to have both???
what is the slope of the roof your on in the video? looks less than what the industry standard slope calls for with a shingle install. What slope does the manufacture recommend for this detail? Looks like such a low slope, driving rain could penetrate the ridge. If it did leak, it would not likely be enough water to show up through all the attic insulation, but just enough to get the insulation wet, possibly lead to mold.
Will the ridge vent suck air out of attic cavity that has entered through holes cut above soffit vents if there are no baffles that direct the air up to the ridge vent? Finished attic with sloped roof. It appears that the insulation on the sloped part of roof is against the back of drywall and not up in the cavity and it appears that there is space for air to flow. I may be able to get a baffle in, but not likely all the way up to the open air above the ceiling.
Hello, thank you for your service... can you help me i have a roof with the back is 2/12 pitch and front is combo 4/12 and 6/12 pitch is there a ridge vent product out there that you would recommend the 2/12 is rolled roofing Thanks Ray
Hey there and thanks for the question! Most manufacturers recommend at least a 3/12 pitch for a minimum. Perhaps you can use the ridge vent on the more pitched parts of your roof.
What about a Foam ridge vent? Just had it installed on my 12x16 Gambrel roof shed with GAF HD shingles.. I thought I was getting plastic when I originally purchased it🤷♂️🤷♂️🤷♂️
Great question! I don't see any problem with the foam ridge vents although I PREFER the plastic ones. There are certain applications for the foam ridge vents and since it's one a shed, I think it will work just fine. Thanks for the question!
Zach! Thanks for your video! I am planning to replace my roof soon and needed help with deciding the vent system. I have HVAC equipment in attic and have power attic fan(which is not working right now) Most of company those I talked to told me to install ridge vent but I heard that having both ridge vent and attic fan is not recommended since fan will suck up the air from ridge vent. I was thinking toward to install ridge vent and remove attic fan instead of fixing the attic fan. Do you think ridge vent will provide enough ventilation even with HVAC equipment in attic?
Great question! That really just depends on the size of your attic and how much ridge you have available on your roof to install a ridge vent. You are right, you don't want both because the systems will work against each other. A ridge vent itself will provide plenty of ventilation IF you have enough ridge available. When in doubt, I would install some large mushroom style box vents in lieu of any other system. I hope this helps!
@@DigitalRoofingInnovationswow! Thank you so much for fast reply! I have about 500sqft of attic space and have about 30ft of ridge available for new ridge vent. I tried to research the vent ratio and calculation, etc. It was kind of too technical and complicated for me to judge if I have enough vent. What is your thought on this?
Ridgevent is made of plastic so there is no function to open and close it. You always need your attic to be ventilating no matter if it is winter or summer.
@@DigitalRoofingInnovations This is a garage ridge vent. Being warmer in the winter may help the use of the garage. I don't put my car in the garage. No need to get rid of fumes. Being able to close it may help retain the heat of the day. Some had passive solar on their garage for heat and holding in the heat may help also.
@@Shasha8674 no ridge vent opens or closes. If it has an attic space, it needs some sort of ventilation or you will blister the shingles due to the intense heat in your attack space. I would suggest you talking to a local contractor about specifics. We have another video about roof ventilation here I would suggest watching: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Z_60QGlZIzQ.html
I just asked this question to a GAF CERTIFIED INSTALLER. He said GAF wants the ridge vent only and that he will remove and plug the existing box vents. By the way, if you have a GAF roofing system installed by an ELITE CERTIFIED INSTALLER, you can get a 50 year non prorated warranty with a 25 year workmanship warranty. I am not aware of a better warranty out there. If anyone knows of one, let me know. I looking into replacing my shingles.
How much more money will you make on a project selling ridge vent details in lieu of hat vents? You lack confidence with your field guys ability's to install water tight hat vents?
You mentioned you don't like the box vents because of the hole needed, however, you need to cut a longer hole in the ridge to use a ridge vent. Kind of negates your argument.
This is the 3rd roof on my house in 30 years, I decided to go with the ridge vent. I'm not real happy with it. My old vents were aluminum, no rusting in Canadian weather, metal screen all 3 were ok. I installed what looked like the exact same ridge vent as yours. It is plastic which squirrels and raccoons like to chew on, it is stiff and did not go down flat with 2 guys installing it. Once the ridge cap was on it with longer 2" nails, it was almost flat to the shingles, still a few waves. It is way too stiff. It is also imperial in size and 3 tab shingles that are 36" long fit perfect. In Canada though our3 tab shingles are 1 meter long or 39 3/8". They do not fit without trimming about 1 1/8 off each tab. This metric system is not all its cracked up to be, PE Trudeau introduced it in 1980 and it does not fit with us being located so close to the USA who have not switched. Architectural shingles also need to be caulked along the edge of the vent. Next time I will try something more flexible.
Do you recommend eliminating the box vents, once the ridge vents are installed? A customer wanted both for more ventilation, does it make much difference?
of course not! LOL Noone in their right mind would make a roof vent make of rust prone steel.... i think the dude slipped up there... no worries, it happens
Hello I enjoyed your video and have a question. Would you recommend a ridge vent on a shingled single mobile home without an attic ? it has about 4 crushed aluminum box vents up there now. IM making plans at the current time to have a new roof put on and the roofer recommended a ridge vent but I seen a video that says it is a bad idea and to stay away from it.
Zack I live in Florida every Roof that has a plastic Ridge Vent the Roof warps and over time It leaks. Especially with those Metro Dade Plastic Vents. Remember Metro Dade Aproved houses built with Plywood and Two By Fours with Stuko on the out side. When Hurricane Whilma came through Kendale All those Houses got Destroyed. I would Trust a Padro to approve anything We Just Had a building Collapse in South Beach.the are Garbage. Plastic Changes and Drys out in 90 degree Weather then When it Rains. It leaks. This is not opinion its a Fact. Everybody that has Ridge caps There roofs are Warpped.been in my House since 1974. Only had Spinners turbines. They Just Did my Roof I requested Snorkle type Vents. The Asshole Sales man wrote Ridge cap. I'm pissed.want them to Repeak my Roof and install Snorkle Type. Like I said Juzt Go Round MY Nieborhood and see warpped Roofs because of Ridge caps They suck
Thanks for the good info and for your service to our country. I was trying to find if there is a certain ridge vent for a very low slope roof and how to install it. I have a steep roof with architectural on one side, and rool on on the other side. I am worried the roof vent won't have enough overlap for the low slope. If anyone has any advice let me know.
Andy, check the manufacturer recommendations on the minimum slope for ridge vent, but the rule of thumb is normally a 3/12 pitch. If you need help getting your pitch, here's our video how to easily get the pitch of your roof slopes: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-yb8mIvNGbgQ.html
Bud, I have been roofing for quite some time and haven't seen a squirrel chew threw ridge cap and ridge vent, but maybe you are dealing with some bada** squirrels where you are!
@@DigitalRoofingInnovations If you google "squirrel chew ridge vent" you will be able to see some ridge vent baffle plastic damaged by the squirrel....
@@wkk6478 Squirrels and other rodents can also find themselves in box vents as well. This is something that doesn't happen frequently. I have ridge vent on my home.
I just had my roof replaced I knew nothing of ridgecap vents which they chose to put on my roof the contract stated two turtle box vents to replace the turbines, they put one at every peak every!! theres a whole long story to this but what I want to know is since they did that my house stays waaay colder than before roof and my heat has to be like 71/72 vs 68/69 its like being outside inside my house unless I raise up the heater. So can to many make your house colder in the living space not the attic need solid honesty, please
Nan C, I have re-read your comment and I am not sure what you're asking. You want your house to be cooler and vent properly. Having extra heat in your attack is going to cause the lifespan of your shingles to deteriorate more quickly. Also, your cooling bill will be lower in the summer.
I think she is talking about colder months. If you have too much venting, the attic will be in negative pressure. Causing heat to be sucked in thru penetrations in the ceiling or walls. So heat escapes from the living space into the attic than the ridge vent. Make sure your attic is not over ventilated.
@@Faruk651 Yes that is what I was wondering cause all anyone says is there great for your attic but geezz the Winter was colder in my house than normal and this summer I have had to run my unit and three window units and I'm in Tennesse. I think there are too many for one story house and its sucking all the cool/heat out of my living space as well 😬. Thank you
@@Amanda-Lee33 There is a calculation for how much intake (soffit) and exhaust (ridge vent) you need for a house. I have a long continuous ridge in my house and i didn’t install ridge vents to cover the complete span which would be too much exhaust and create negative pressure in the attic.. Maybe your roofing installers thought more is better. But i don’t know your house so i might be wrong.
Yeah not a fan or ridge vents, side peak vents have done the job just fine for 120 years. Makes no sense to put in a strong water tight roof then when your done to cut a hole across the whole roof. Where we live we get strong winter icy winds.
he says box vent "can still leak because you're putting it on top of a hole." Well... Ridge Vent goes on top of a hole, too, so... holes in the logic. I haven't finished my research into the various vents, and implications (from the perspective of an existing house, not new construction) ... but I think this video would have been way more useful if it focused on education and facts, rather than his opinions expressed through persuasive salesmanship.
I'm not really a fan of something you have to go up on your roof and clean out once or twice a year. It's hard enough to keep having to clean out the gutters. No thanks

You need ridge vent because the money hungry contractor needs to make money for useless crap that is prone to leaking event when installed correctly. Say ok to holes in your roof. Go for as much soffit venting as you can get and put in gable vents. Ridge vents are for rich suckers
