after pulling the roof jacks

asinning | Posted in General Discussion on July 22, 2006 06:24am

I had to fix some rotten wood around a dormer on my 12/12 roof last week so I bought a pair of roof jacks. Each jack has 2 sets of 3 nail holes (tear-drop and slotted). After a few misses I found the trusses and sunk 3 nails for each jack, straight through the top of the shingles.

Now it’s time to pull the jacks. What’s the best way to repair the damage done? What’s the easiest way? What would be “adequate”?

Oh, and while you’re at it, could somebody please tell me what the correct way to install the jacks would have been, for the next time I venture up there?

Thanks!

    I would have removed the jacks but left the nails and then sealed them with roofing sealant. A little bit goes a long way, you don't want to leave big globs of it because when it gets hot it will run and leave big streaks down the shingles. I would say that your best bet at this point would be to fill the holes with sealant and wipe off the excess with your finger.. pressing it into the hole as you do.

    You lifted up the shingle flap before nailing, right?  Just hit the holes with blackjack and re-seal the tabs back down... call it done.

    If you nailed thru the shingle pull the naills-slide a tab of light gauge metal under the shingle and covering where the nail holes are-then proceed with the Geocel.

    Next time seperate the shingle tab and lift it and nail the bracket so the tab covers the nails.

            No big deal... now you know, right?  So set 'em up the right way, about 5' down the roof so you have a nice comfy place to work from while you're fixing your first mistake.  :)

            These guys are the best huh?  A piece of aluminum flashing... how easy is that?  And effective too.  But now I gotta find out what 'geocell' is as Sphere's telling me that Blackjack is yesterday's news.  Tough keeping up with these cats.View Image

            You have an ABC Supply up there nearby? They got Geocel in many forms/and IIRC colors besides clear, driftwood and white.

            Grant just got some kind of "recognition" from someplace, cuz we are the largest user in KY or something like that.

            EXCELLENT stuff. I still 'import' Lexel when the wife goes down to NC tho'..I like it for my odd ball house uses, and the stuff in my van from Grant is for job use, not my personal use.

            There must be a supplier of Geocel in Mass., Tom Silva advocates the stuff so much that I've had clients buy it just so I would use it.  Down here in Conn., Rings End carries Geocel, True Value stocks Lexel.

            Just a note.  The instructions on Lexel say that it is not reccomended for use on asphalt.  it tends to turn a yellowish brown and never really set up fully.  it will still work though

            these guys are fulla crap..

             black jack is still the roofer's choice... absolutely , positively, gauranteed to do the job, and your tools, and your clothes ,and your hair, and get on your boots and track into the house...

             or ...  you could take a rag with you and avoid all that

            the aluminum slip is fine.....but....

            so is lifting the tab and squirting blackjack into the three holes , then closing the tab down again...

             the three holes in the top will not show up and they won't leakMike Smith Rhode Island : Design / Build / Repair / Restore

            Whatever floats your duck. I been with Grant almost 3 yrs and countless roofs. Never touched any black jack or roof cement.

            I hate the stuff, besides we'd look like hacks doing a counter flashing that way, and one more item to stock in my van..you can have it.

            I mean when WE counter flash, I'd still use Clear Geocel, so to patch a nail hole in shingles I'd need to stock black jack as well, We just dont use it.

            if you  lift the tab and squirt the geocel / blackjack in... it don't matter what color the stuff is

            gives a better seal.. and doesn't mess up the face of  the shingle  ( any more thatn the three nail holes already have

            some will even ooze up into the nail holes and you can still apply your granulesMike Smith Rhode Island : Design / Build / Repair / Restore

            What about "thru the roof", it is a new clear roof caulk.

            Geocel proflex caulk is awesome, but never used it for roofing.  Counterflashing yes, but on shingles, I don't know.

            just my two cwnts

            I use Through The Roof a lot. Both in the gallon and in the cauld tube.It is expensive (especially in the caulk tube!) but it is a lot easier to deal with than black roof cement, and it really works well.I can see how the Geocel 2315(?) is better than the Through The Roof(TTR), but right now I pay double for the Geocel than I do for the TTR. Plus I can get the TTR at my local hardware store, for the Geocel I have to get it delivered from an out of town roofing wholesaler.But if you have something that doesn't want to lay down, then roofing cement is needed or something to hold the whatever in place while the TTR or the Geocel cures.The Geocel is compatible with rubber roofing, an important advantage over the TTR which is labeled as no for use with rubber roofing (despite the front label claim that it is for use with all roofing materials!).Rich BeckmanAnother day, another tool.

    right way is to lift shingle tabs in moderate temperature and nail jacks under them. Then to remove, you tap up from bottom and the jacks slide off the nails, which you drive and leave.

    But sometimes conditions demand that you nail on the surfacce. To remove them I pull the nails, and slide a slip of AL or CU up under the shingle tab where the nails holes are. I use some caulk in the holes to glue it there

    I typically repair a nail hole thru asphalt shingles by taking a sliver of asphalt shingle about and inch longand slightly bigger than the hole on one end. Pound that into the hole. Hole patched.

        Yup, keeps you from having to carry a caulk gun when pulling jacks.

    "Now it's time to pull the jacks."

    You could just leave the jacks up there. Around here it isn't TOO unusual to see a roof with the jacks still on it (sometimes the planck across the jacks is still there, too!).

      there was a house on main street had two rows of planks and the jacks on a new roof for years..

       slowly but surely  ( shirley you jest ) the planks rotted and sagged and eventually fell  off the roof...i'm pretty sure the jacks are still thereMike Smith Rhode Island : Design / Build / Repair / Restore

            You laugh - but about half mine are painted. I sometimes have a bunch of moldings that get pre-painted, so I set up a painting table which is planks over sawhorses. The planks get a good coat

      LOL, I know wheere there is one with a pair of jacks just below the chimney and where a dish ( the six footer) was mounted. The plank has since rotted to the point that there are only shreds of wood hanging between the jacks. I can only imagine what shape the jacks are in!
