How to Install Whirlybird Roof Turbine Vents | 72 

Also, they spin better if they're placed a bit higher so they catch wind from both directions. Overall good effort!

Thanks for the praise! I used a lot of sealant too so hopefully that makes up for the shingles piece; we have received so much rain in California since installing these and its all held up without issue. Appreciate the extra insight too - gonna pin this comment as its constructive and helpful for people looking for tips.

I just went off of the recommendation for square footage - I wouldn't overdue it both for the cost of it and incase too many compromise your roof

Glad it was helpful! We sound very alike and to be honest it's a super simple quick project as long as you can mentally get over the hurdle drilling a hole in your perfectly good roof!

Thank you! 😃

my pleasure

I just followed the written instructions exactly and it’s held up great ever since with the correct roofing sealant

I would add - its super simple and it will just help your house life. good call on the straight edge.

Thanks! I think I did do that though? Cheers

@@workshop_edits You did lift the tabs to set the base under the upper shingles, that was pro. The video doesn't`t show you actually nailing through the shingles but at 15 minutes there are nail heads through the shingles, I`m suggesting to lift those tabs and nail the base to the sub roof and then drop the tabs back down and the nails would be under the shingle. 🍷

The rising heat and a tiny breeze makes it all function

I don’t think I’m qualified to give that advice. These are pretty standard and I followed the guidance in the install directions which feels very universal to roofs overall

@@workshop_edits thank you 👍

I have before - on hot days - lets say 90-100 degrees - at the peak they were in the 120s+; I have not had a hot day yet (I installed these two days ago) to really get up there and see how it vents. I will say in the two days though, I have noticed my HVAC system running less to maintain the same temps. Right now its 90 ish at my house with a good breeze, they they are working overtime. the attic feels much cooler.

You're either taking on the risk of the DIY job, or paying a professional for his years of experience - depends how you value your time, what your skill level is, and how you value your roof. You also might have a more complicated roof than mine.

@@workshop_edits how long would you say this took you?

Thanks for sharing, I too am refusing to pay $400 a piece for installation of two of these.. I think I can follow all of the instructions and do this myself.. $800 for Labor is ridiculous!

Just remember that you’re paying for professionalism and experience, not necessarily exact hourly labor. It’s a pretty doable easy DIY project, but if you hire a pro, you have to pay them like a pro

@@andreagriffin2485I would say the total install time was probably 2 hours.

I wish I could answer this but no I did not take readings and I wouldn’t be able to tell you if there is a meaningful difference. That being said having these does circulate the cool air in and help your roofs life expectancy so to me they were very worth it knowing they also are helping alleviate the heat - I just don’t have data to show my own before and after

Yes you need to have soffit vents to allow the current to flow in and out

Thanks for the info and very helpful video for the average homeowner who doesn’t know much about attic ventilation!

the angle of the base aligns with the pitch of your roof - that's why you see me using their template, then its marked to just allow you to line up and secure. I just used black polyurethane roof and flashing sealant from Loctite - that seems to be the right thing

I installed it 30 inches down from the apex of my roof; there is no reason that being too low on the roof should in anyway affect your ability to level it - those two things are not correlated

oh ok its weird i tried rotating it and got the same result, i even used the leveler each time but someone it would come out slanted. @@workshop_edits

I recall needing to do two things - one was set the pitch, the other was rotate. It’s been a few years so I’m not 100% sure without the directions but they’re universal and you shouldn’t end up with a slant if you follow directions regardless of pitch. Sorry I couldn’t be more clear

sides

@@workshop_edits of course 👍

Yes

@@workshop_edits my house currently dont have any vents on top but a gable vent on one side. Would adding two of those turbines be enough for a small home? I currently have mold issues growing on the bottom side of the attic wood.

@@workshop_edits also how much difference do you feel now compared to how it was before? Do you feel a major difference in temperture change during the summer heat?

I’m not a roofing professional so I can’t speak to anything beyond what I installed for my set up and house size. I notice very little difference because an attic still will get hot, but I do know they are also keeping my attic healthier long term

What do you mean by access? Like to install, or after installing? What do you need to access them for?

I think she meant marking the middle of the center point without going inside the attic.

I installed three of these by following your videos . Unfortunately Home Depot no longer have colored one in stock in my area so I got the silver one. Two of them are doing great but the last one isn’t spinning as much as the other two. Summers coming up so I’m hoping these would help lower the temperature. My attic last summer was 138 F in California all I had were gable vents and one intake. Now with 3 whirly birds installed I’m hoping it would help this year

These are water proof if installed properly - if it fell off then there is a hole in your roof so water will get in but it probably is fine. Put a tarp over it temporarily to mitigate things. $500 seems right though - you’re paying for their professional experience and materials, not just the hourly installation.

Different houses have different types of vents - houses in my area are are near mid attic level, whereas other areas might have soffit intakes

is it newly installed, or old? it needs to be level to work to its fullest capacity; but old and worn down or bent bearings / alignments could be an issue

for water protection you mean? I can see how that would be a good idea, but between the sealant on top and bottom and the overlay (and a HUGE amount of California rain), it all does seem to have held up totally fine as it but the point is taken for others!

Probably picking his battles. Garages with little insulation or climate control really need ventilation to keep it even somewhat usable during summers (at least in SoCal)

@@workshop_edits SoCal. I KNEW it! I live in southern California as well and because of the surrounding environment and your comment, "it's kind of like an awful place," was like, "That guy could ALMOST live in my city." That said, I'm glad I found this because I'm installing whirlybirds soon (well...replacing the old ones; they're worn). I was glad to see that there was no insulation on the bottom part of your roof, either (in the attic, that is). Same house builders perhaps? I was afraid someone neglected something, but maybe that's how it is here. At any rate, QUESTION: How did it work out for you? Quite noticeable difference? Do you know what the temperature in the attic was before and is now? With my broken whirlybirds, my temp was at >140℉, which is WAY too hot. It was leaking into my house via the attic access panel. I've installed soffit vents into the eaves, which allows intake of "cool" air. I'll see how it goes. ¯\_(ツ)_/¯

Feels like an 8.5 at a minimum

I cover this in extreme detail upfront

putting those whirly bird helps eliminate moisture when its hot, as hot air if not removed turns into humidity thus having a fan or a whirlybird will pull the hot air outside.
