That’s how to make a relatively easy job look difficult. An electric multi tool will do all the cutting much quicker and the end result will be neater. Also if you install the vent as high as possible toward the ridge the flashing will only need to be placed on top of the roof as the ridge cap flashing will partially cover it. Also doing away with all the other cutting to the roof. One circle will be all that’s required.
@@SteveAZ711 a larger flashing placed under the ridge cap would still allow you to keep the same vent location as u have without the extra work . Regardless of beams , underpaneling or anything else. Not trying to be critical. Just a little more helpful to the next guy wanting to do something similar. 👍
@@DouglasFir90 There are several ways to do the same job. But there are always those that have a "better" way after the job is done. I wonder why they haven't made a video? I'm always open other ways but if they have one, how about a video instead of just using their keyboard? Just a thought.
problem with grinder is it heats up the metal and causing it's easy to get rusted later on. need to brush the cutting edges and treat it witl rust proof prime.
An easier method is to install the fan base completely under the metal roof, cut your perpendicular slots 1" inside the edge of the base, and slide in another piece of r-panel with the hole cutout under the slot. You can overlap the new section 4" over the down slope roof, and you only have the end of the slot to waterproof. It works great because you can install the base while you're installing the roof, and come back later to cut your decking.
You seem to live in the dessert so water probably won't be an issue . Since I'm in the Tropics I probably would have to build a small shed thing so the hot air actually travel side ways a bit before exiting the turbine to avoid direct rainwater . TY for your Vid data and Exp !
These turbines do not let water in. I know that it looks like they will, but they are designed not to. here is a link to their site for some more information...www.lomanco.com/vents/whirlybirds
You would be amazed at how much it rains in the Arizona desert. It doesn't rain often, but when it does, it is torrential! These fans do not let water in.
If I already have cut a ridge cap vent do I need turbines? I was told I did not and replaced the wood removed from previous turbine installs. I do still have an attic fan to help exhaust heat if needed I was going to keep. Was watching this to get an idea of how to metal roof around it and flash it. So now I'm wondering I should have kept the turbines as well. It's pretty hot and rainy in South AL.
If you have a good well vented ridge cap then I would not bother with the turbines. Your attic fan should be sufficient as well. If you have good air flow from under the eves into the roof cavity, then the fan and vents should be enough to keep it dry in there.
It’s defiantly a weak spot , I personally don’t rely on silicone to keep leaks out , I prolly would have made a second piece of flashing to cap those then put the vent over it . So that the Lao is correct
It is an idea if you can fit it under the ridge cap to deflect the rain. Still going to have to do some caulking at some edges for those wind blown side driving rains. This metal roof has a water proof membrane laid under it and if any moisture was to get under the metal, then it would be channeled to the lower roof edge and away from the roof.
I would refer you to this site for more information...www.lomanco.com/vents/whirlybirds.I have installed 5 of these on shingle roofs and they are very much easier than doing them on metal roofs. Watch some of the LOmanco Whirlybird videos and you will see what is required to install these. Thanks!
Doug, here is a great product for just that repair(last link below.) Here is a RU-vid video of this stuff. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-MkafpRO7yqg.html I have used something similar around an inground water drain pipe and I will post a link to that as well. This stuff really works. Here is what I used and it is made by the same company... amzn.to/2XK7MUI Here is the link for the roof stuff. It is not cheap and please read the instructions as it can be life threatening ..so be careful! Here is the link... amzn.to/2LEvb3n
Be sure not to cut through the trusses. Position the hole between them or the rafters and between the braces between the trusses or rafters. This was a clean hole and well positioned. FYI.
I heard 4 opinions on rain. 2 said rain will come in these and the other 2 said it won't.. I want to find out the truth about these but its hard when everyone has opposite opinions?
This whole process could be avoided if I cut 2 inches in the ridge on each side and put a 10-inch ridge on each side as if it were ridge vent on shingles, well it is my opinion because metal turbines always leaks
I think these turbine vents are really ugly even when they work properly. Driving around in my neighborhood, I have seen at least 6 or 8 houses where it looks like their round turbine vent has become dislodged from its original installation and those round vents are just dangling sideways off of the vertical pipe. So just the metal tube sticks up from the roof and it looks like the round turbine vent is only being held onto the side of the tube by one or two screws or nails. We get wind gusts up to 60 or 70 MPH here every year, so perhaps the wind is blowing all these turbine vents off of their pipe tubes? How are these turbine vents becoming detached from their tubes in my neighborhood?? What happens to these homes' turbine vent tubes when their top turbine gets detached and just dangles on the side of the tube? Does that mean there is a big open space for rain and snow to fall straight into their attics?? A lot of these houses with their detached turbine vents have been like that for several years now. These are all two-story houses, so these homeowners cannot even see their damaged roof turbines from their front or back yard because you only notice the detached turbines if you look at these roofs from a distance away.
Hey Claire, Yes they will get snow and rain in their attics if they are not working as intended. I agree with you as to the aesthetics and overall appearance of turbines and custom houses. I do not know what brand of turbines that theses houses have, but the brand I put on my roof is a guaranteed replacement forever. Yes, it says "forever" right on the box, and it its designed to withstand 60 mph winds. I have used different brands and most except this brand has to have some kind of attention paid to them once in a while. I thought about solar attic vents but the 20 year guarantee turned me away from them , even though they look much nicer with a lower profile. Plus, can you ever really know if they are working , and what about cloudy humid days? An attic needs ventilation year round 24, 7 and I was unable to put passive gable end vents into this section of the So Slow house build. Believe me, the last thing I really wanted to do is cut another hole in my beautiful roof, but to me I settled for a bit of that commercial building look to know that my roof with its attic ventilated should last much longer. Later I will be putting in a wood stove, and I am not really liking cutting that hole either. Thanks for the comment!
Hi Steve, at least your turbine vent is installed on a metal roof so the metal turbine and metal roof blend together more. In my neighborhood, those turbine vents are put on top of custom and semi-custom two-story homes, and I think it really ruins the aesthetics of those homes. And now that those round turbines are dangling vertically along the pipe tubes at awkward angles, they look even uglier. These are not very old houses - the houses are all 10 to 15 years old - so some of these turbine vents likely became detached within 5 or 10 years after installation. And now some of those homes have a big hole facing the sky because the turbines somehow became almost completely blown off of their tube mounts and are dangling by just one or two screws holding them to the tube. Along with moisture damage from rain and snow entering the attic, I wonder if birds and wasps are also flying through those exposed turbine vent tubes and building nests inside those attics. I'm in Denver, and we can get a big downpour of rain along with hail during spring and summer, and 6 to 12 inches of snow sometimes during winter.
It sounds like some repairs are needed badly. If you let holes go unattended for too long the roof repair costs go up more. You pointed out some good examples of what could happen. I am sure you will see some roof repairs being made at some time, and the sooner the better sounds like. Thanks for the reply!
Oh, one other comment after watching your video. The thin sheet metal used on the turbine vent, elbow, and base does not look that strong and durable. It looks like if you lightly kicked the elbow with your shoe, you could easily dent and deform that metal tube? Perhaps when those turbines are hit with 60 or 70 MPH wind gusts every year, eventually the turbine vents can loosen and tear away from the elbow tube that they are mounted on, and that is why some of the turbine vents are become detached from the elbow tubes in my neighborhood?? I only started googling these turbine vents because my husband wants to install two vents on top of our roof, even though our summers are only really hot for about six weeks in July and August. So I drove him around our neighborhood and pointed out how at least 8 houses have their turbine vents detached and dangling from their elbow tubes. And I told my husband that I did not want him climbing up our steep two-story roof to fix a gaping hole in a separated turbine vent elbow tube. And I think the turbines are ugly even when they are mounted properly and working correctly.
Claire Hi, I just checked the box that the turbine came in and I was mistaken about the 60 to 70 mph wind. The box says " tested to 110 mph winds". After a 110 mph wind I would be more concerned about how much roof was left. If you have an attic, check into gable end vent fans. If you can get into your attic is probably much safer than being on a 2 story roof. Also, check around and find some good working turbine and see if the owner has anything good or bad to say about it. Perhaps, you can find someone that installs these as well. Stay Well and thanks for the comments!
@@SteveAZ711 lol . iv fitted thousands of whirly birds / vents to houses and factories . this way he’s doing it we call a deck fit . cut into the sheet deck pan . piss easy to do . cut the sheet with hand snips and then cut the ply out with a sabre saw with a jig saw blade fitted to the sabre saw !
Thanks! It was getting quite warm up there 90 + degrees outside, trying to keep from sliding off a slippery roof, and a tad overweight at the time... and then there was the camera that was probably going to melt. Those metal roofs can get very hot quickly and my slippery Knee pads were getting quite warm as well. However, the install went well and I was no worse for wear or the camera afterward. Thanks for your concern!
