How to install a spinning roof vent or whirly bird on a tiled roof

[@MrDerickComedy]

Glad to see you installed it at the right angle! Can't believe how many of these i see that aren't installed level.

[@dennisperrie]

True

[@jaichithjeyakumar507]

Should it be in the right angle ?

[@Bob-ox3ci]

Thanks for the video. It does suprise me that water sometimes doesn't get blown back up and in!

[@kantijainuddin751]

Sir, the explanation and disciplined work is very easy to understand and very helpful for me. I wish you continued excellence in the future.

[@sowhat3430]

Just wonder is there any flexible aluminum pipe connecting with these whirle bird vent or it just ventilate the air within the roof ?

[@bdbd9698]

great vid buddy, nice easy to follow 👍🏻 topstuff thanks 👏🏻

[@kevinwkjw]

Nice video mate,, should there be two or just one enough,,, just a thought,, one to push in fresh air and one to push out ,,,,

[@dennisperrie]

Two is better than one I think

[@markhodges1276]

Air generally is replaced through the eaves - the lowest point of the roof. The whirly bird spins due to the hot air in the roof cavity creating a higher pressure than the outside, so air flows from the roof cavity to the atmosphere. The air being pushed out through this process is replaced generally through eaves and other entry points (roof cavities are designed to have airflow).

Appreciate the video - any Caulk necessary?

[@dennisperrie]

No it should just slide under the tiles.

[@bazza2825]

good vid, do you think eave vents with these are necessary or not. cheers.

[@dennisperrie]

It's not necessary but is an option to increase air flow

I have an indoor pool. Replacing the roof (leaking, poor previous install). Never insulated before. Planned to be lined with sisalation/sarking. No insulation as concern about moisture/fungus. Considered 2x whirlybird for better ventilation for pool/water moisture, bit now hearing how loud they are is putting me off- even more reading what youve written. Are vents worth it in my situation, & if so, solar vents?

[@dennisperrie]

Both are good. Spinning roof vents are only loud if the bearing is damaged or they are deformed and scraping. If installed properly they are very quiet.

[@Louieinoz]

when installing a new one. whereabouts do you determine you should install it? I mean how high up on the roof? I live fairly coastal so I'm concerned the winds will blow it over

[@dennisperrie]

That is a fair concern. There are a couple of ways to address this. 1 move it lower on the roof (However depnding on the side it on the Whirlybird may still get alot of wind.) 2 Put it on the face away from the weather (this may reduce the wind hitting it in the hotter months but aslong as it getting a good steady flow it should still work fine. 3 Silicone down the sides of the flange to the tiles as this will increase it's anchorage . ultimately it's a judgement call. you can use a combination of all 3 if you like. If it does get blown off remember you can always move it down the roof later. just keep the tile you pull out to fill the existing hole.

Hi I want to know if the outside temperature is 45 Degree C and the inside temperature is 40 C. Bu installing Whirlybird in each room will reduce how much temperature inside the rooms?

[@dennisperrie]

The whirlybirds is designed to remove the excess heat from the roof cavity not individual rooms.

[@aga5979]

What is considered excess heat? Wouldn’t all roof / attic space have excess heat. If excess heat are seeping / radiating through the insulation to the inside the house, the vent surely should help? Nobody has recorded the temperature before and after? Thanks for the video.

[@akanesoratobu8889]

does it matter if the whirly bird is installed at a slight angle?

[@dennisperrie]

It is not the correct installation, but I have seen it on roofs, and it still spins. It is more efficient if installed level and I am not sure how it affects it when it rains.

[@akanesoratobu8889]

yea i tried leveling it but it always comes out a bit off on one side. Its not a lot but about 10 to 15 degrees on one side. Its spinning but im really hoping when it rains it dosent come in @@dennisperrie

[@firsttechnology5094]

I would bend the top of the flashing up and forward to stop high wind blowing rain water under the tiles...

[@Felixkoifish]

Thanks

[@Mark-p3d1q]

Why didn't you "weather" top of the flashing?? Water will pour in with rain

[@dennisperrie]

No it will be fine. it slides under the tiles plenty and the direction of the rain and storms blow the rain down the roof. Also being soft zinc. the base will conform to the tiles and they will sit low on the base however if I bend the top over It will create a lip that will cause a lift in the tiles, opening the tile joints.

video maravilhoso!

Can you install one for me ? What is your mobile phone?

Hi Dennis, Thank you for your videos. Great details. What areas are you working in? How do I contact you for your services? Thank you

[@dennisperrie]

I work in Northam suburbs of Perth W.A.

These “roof vents” are the most useless things ever invented 🤷‍♂️ they do stuff all given most people only put up one of these on their roof. Dry ridge caps are a lot more useful, but nobody seems to be doing them Down Under.
