roof jacks on cedar?

Sphere | Posted in Construction Techniques on June 6, 2004 03:25am

I should know this..I’ve done it before..brain fade has set in and for the life of me I don’t remember what to do to cover up the places I will have my roof jacks nailed to the roof.

On three tabs, I just shingle over them and then knock the jacks up and out, lift the shingle tab and whack down the nails..but on cedar..I’m thinking I need to drive a shingle up and in..and either finish nail the face or just let it split along the upper course nails..?????????

I know Andy C is doin the same right now..so Andy? what are ya doin? Mike Smith? Any other ideeers..

Also, the spongy nature of cedar breather..well, dont the jacks kinda wobble on that? I’m not at that phase just yet..doing the upper dormer that’s not being jacked..BUT Tomorrow I’ll be on the 12/12..and 10/12…..note to self..go buy more jacks.

So..any help folks?

    I ain't no roofer... but what happens if you just leave the nails? Are they on top of the felt? If so, it seems like they'd just 'imprint' into the back of the shake with a bit of shoe pressure. Another way might be to cleverly install the jacks so that they end up between shakes, and then you can stick a nailset in the gap and seat the nails after you pop the jack. Or, just go to REI and buy some crampons and skip the jacks altogether.

      leavin the nails might be an option..they are 2.25'' ring shank galvies..they won't press into the sheathing to well, and I try to get my jacks over a rafter..

      putting on a seam and nailset? won't do that.I try too hard to make all the nails covered well..self defeating.

      cramp ons..hmm..if they made little bitty one for all the tools on the roof..that might work..this one has too much pucker factor (altitude) to not have jacks..40+ to the ground at one part..

      TO ALL...MAX SIDING NAILERS ROCK!!!!

        Apparently you got your shakes. Good deal. Make sure the jack nails are covered by a shake and knock 'em up and off when you're done with them. Consider which lateral direction  the jacks will move when they're sliding off the nails and decide on the shake width accordingly. Leave the nails (you are using 16d's for the jacks aren't you?). Give me a call when you've got time. I've got a job for you to consider.

            the way I remove roof jacks and sidewall brackets is to save the shingle that fits in the spot where the bracket is nailed then remove the bracket and tap the shingle up until you are about a 1/2" away from where you want it then toe nail a couple of stainkess steel siding nails up under the upper course and set with a nail set ,then use a block of wood to bang the butt flush . Done it a 100 times works great and no exposed nails or risking a leak nailing thru seams

            I dislike roof jacks.  Rent a nice system scaffold with swivel jacks.  Pad the mud plates and your “in” like Flynn

            Lets you work like a gentlemen.  I like the flat work space at the roofs edge.  I use roof jacks only when I have to.  

            I found the extra coast to be justified with all that room and safety.  Plus we get done faster with it.

            no can do..too much mature landscaping..and that won't help much at mid roof and higher

            Semi-hijack-let's say you want to use roof jacks on a finished roof, and you're not re-shingling.  (Three-tabs.)  Do you lift up a tab then nail the jack under it?  Just curious.

          6. seeyou | Jun 08, 2004 12:25am | #10

            That's the way it SHOULD  be done.

          7. xMikeSmith | Jun 08, 2004 04:19am | #11

            wood.... that's the way we do it also...

             some times we put a small square of ice & water over the jack nails after they're nailed flush..  then slide in the saved shingle... that was sitting under the jack  to protect the other shingles from marking by the jackMike Smith   Rhode Island : Design / Build / Repair / Restore

            thanks for the back up i usually spline it with ice and water and or a pieceof copper step flashing. I see to many guys face nailing these fillers and where I live on the ocean exposed nails are a bad idea and thers nothing worse than a leak with shakes

  2. andybuildz | Jun 08, 2004 02:58pm | #13

    What I've been doing is using water/ice shild under the nailed areas.

    Tell my guys not to nail anything super home just to make it easy to remove the nails and not gaouge the shingles when remove the brackets.

    Then I've been using a two part epoxy in the holes and shoving a splinter of cedar into the goopy hole.

    No leaks and its been pouring here and no drywall inside so I can tell its worked great.

    Have fun bro.....Just bought me a third Max gun and eel hose.rocks, right??

    I'll be selling the third gun when I'm done cause I really doubt I'll ever need three guns again, although I've had slews of people stop in to ask my wife if she;s happy with her contractor because they love how this is looking...she said shes so happy with him that shes sleeping with him...lol.

    What a joker....too funny.

    BE safe bro

      Andy,

      What's an eel hose?

      I prefer mine smoked on a small ball of rice!

      "had slews of people stop in to ask my wife if she;s happy with her contractor because they love how this is looking...she said shes so happy with him that shes sleeping with him"

      Andy,

      You crack me up....Actually, My wife's friends often ask if they can "borrow me" LOL for "stuff" around the home.  Lately she's told 'um no, at least not when she's working.

      So how's it going on that roof?  Just got word yesterday, I'm going to have a healthy chunk of the Summer off.  Today...Grouting kitchen tile, pull boat out from garage (IT'S BURIED DEEP IN A CORNER) and replace primary pump impeller, unload 1 ton of pavers from bed of PU, trim shrubs.........the list goes on...And maybe drop the boat in the FIL's lake if I have time. (supposed to be in the 90's AGAIN today).

      so yer just nailin the jacks on the already installed and filling the holes..interesting. I know ya can't slide a filler up an in..the cedar breather will catch it.

      Got my 4th square done today..started actually nailin Sunday AM..the only help I've had is DW cut my starters, and sorts the bundles into like sizes and brings em up the ladder..now that's a good wife..

      Yeah the gun is fantastic..only prob is the nails are plactic collated..and some have come un-collated and cause a misfire..it only happend like 3 times.outta a bazillion nails ( my first case is almost gone)..and even 2.25" nails are too long I think..next box will be 2"

      The HO's are thrilled..it's lookin real nice (from the ground)..no really, it's all dead on..some how my ridge cuts were the same on both sides!!!..LOL

      110 up there today..90 sumpthin on the ground..and man, am I red.

      Be red cedar,red neck..and whatever else is exposed

                       Same thing happened to me when I first used the gun till I got used to it.....or it me.

        Yep, I just nail dead through the shingles and then fill em......I mean how many holes we talkin about....ya know?

        I started with metal collated nails but the plastic ones which I'm using now are a bit more tricky but we have it totally down now and I love em.

        theyre a bit more on their period....lol.

        So far we've gone through 50+ sq and rockin hard......today was a serious scourcher up there so I had my guys load up the van with trash and we made a dump run and that wasn't much cooler but up on the roof was brutal and tomorrows spose to be even worse.......ugh.

        Started painting the gargae floor with Rustoleum two part epoxy paint..almost ninty bucks a gallon and we went through 5 gals.....whewwwwwwwww.

        All in all, I'm in love, heat and all.

        Be loving being a carp/builder!!!!!!!!!!!
