    I forgot one more….
    3. Stop using these vents and do ridge venting instead.

    1. Who would Not use holes already available?
    2. Odd that there are holes there in the first place since you should not be nailing below the shingle line.

    Can you show how this vent is installed on a clay "S" style roof tile? I see a lot of vents installed on shingle roofs but none on clay roof styles. Very much appreciated. Plan on installing one on my clay roof and would like to see one installed before I start on mine. Thanks

    Ok, everyone bitches about the situation, but offers up no solutions!  Like they are holier than thou. A bunch of douchebags

    funny  i saw that yesterday on a house i inspected and on another one last week. The problem is most of the time the vents are not installed by the roofer rather just a handy man. Roofers no better.

    Naturally, most people installing them on their own by hand would use the holes. They would obviously deduce that they are their for a reason, if they hadn't read the information from the manufacturer. The only reason their are nailed in the flange at all is due to mass production, quick roofing: can't put the damn nail gun down for a minute to use a hammer and install them by hand. I am pretty sure nobody who knows much will argue with that. They want to use the nail gun and don't care…

    I put this together which shows a sequence of videos, showing how they were done in the past, and examples of cracking. Youtube will not allow me to post a link to it here, but type in google "active rain improper roof attic vent installation" and you will find it. Shows a sequence of videos with different eras of installation and what can happen when the manufacturer is ignored on the matter of nailing directly into the flange.

  • J Nickelsen 1 year ago

    (part 2) … they changed it and started providing one pilot hole to prevent the cracking. Then two. Then three.

  • J Nickelsen 1 year ago

    Different subject, but I agree with the initial point. Technically speaking, the manufacturer is the one that dictates how their product is to be supplied. On the back side of the vent it says not to nail in the flange. They want you to use the pilot holes. The reason they do is because they know that they often crack otherwise. In the early 1990's they didn't provide any pilot holes. Many of those roofs, due to natural aging, are being replaced, so you don't see them as often, but…

  • J Nickelsen 1 year ago

    Yes, I see that often. More often I see them cracked. When cracked they are either over nailed (driven in too hard), or nailed in the flange rather than the pilot holes that the manufacturer provides.

  • J Nickelsen 1 year ago

    Using the screws with the rubber washers, as described, is a better method. Regardless of whether they are nailed and sealed, or use the washers, the three holes (used to be two, before that it was one, and before that–around 1992–there were none) are what the manufacturer provides. No, there isn't a pilot hole in the flange where it was put. Usually isn't. The reason that they don't want to use them because they have to put down the roofing nailer for 20 seconds and do it by hand. 🙂

  • ChicharonyPresidente 1 year ago

    I agree, that's a shitty job. Probably that job was done by another person who has videos in here namely Paul Miller who installs the vents like that. Exposed nails and all.

  • Jan Senkyr 1 year ago

    The problem is not hole but exposed nail's,they go be rusted and sooooon you have leak problem. And yes holes are in the plastic for reason(cracked plastic mean leak….)

  • Danzchannel 1 year ago

    On 750 aluminum bird proof vents, there aren't "pilot holes." There aren't pilot holes on most commercial roofing flashings and vents. With a plastic vent expanding and contracting, it will loosen the nail, and raise it up…LEAK!! Besides, it would for sure loosen the caulk on the nail head, which should be done anyway. Just my opinion, thanks for posting!

  • J Nickelsen 1 year ago

    Yes and no. The holes that they supply are larger than the shank of the nail. If the holes are used then it allows the vent to move around the shank, whereas if they are in the field (which the manufacturer says not to do on the underside of the vent) it doesn't permit for the slight movement and they then crack. Don't get me wrong, I think that metal is a better option in an area such as this (roofs, being high profile areas). But I wouldn't simply point to the plastic as the cause.

  • Tjfreak 1 year ago

    I'm wondering why I don't hear more about galvanized or stainless screws & weather resistant bushings or washers being used ? I know the decking will swell & contract around the nail but whats the difference with a screw,maybe threads would stay in place better ?

  • Scott Ledger 1 year ago

    I'll bet that under those nails are actually pilot holes. So I doubt it is wrong but yes there should be more nails in the remaining pilot holes. We use screws with rubber washers where they will be exposed like this. Just my 2c
