o.s.b. roof sheathing coming loose

JordanBuilders | Posted in Construction Techniques on August 8, 2006 04:21am

hi,

 

i’m a builder with 20 years in the trade and have encountered something new. i completed a three car garage with apartment above about eight months ago. recieved a call from the client that the roof had “buckled-up in places”.

This roof is standard truss construction @ 16″ o.c. trusses with 19/32″ inch c.d.x.  15 lb. felt and tamko brand three tab shingles. pitch is 5/12″ pith. nothing fancy.

The ventilation is from perforated soffit to the ridge vent which is continuous.

As soon as I talked with the client I made a trip to check it out thinking maybe a shingle got layed without all the nails. No such luck. What I found was four or five spots where the plywood curled up from the rafters and the eight penny nails had pushed up enough to make indentations in the shingles. Upon inspection of the roof system from the attic side I found three places where the plywood was beginning to “lift” up from the trusses and the nails that were supposed to secure them had begun to work loose.

This job is located in northeast ga. where severe heat is not a problem, and should not have been given the ventilation practices.

I drove some 16 penny nails into the bad spots and patched underneath the tab as a quick fix on the worst spots until I got my roofer out there to make some repairs, and thought I would post on here to get some feeback from someone else who might have encountered soemthing similar.

I would appreciate any feedback as I’ve never encountered this and don’t much enjoy callbacks.

 

Thanks in advance for any insight!

    I hate to ask you a dumb question but does it have soffit vents?

    Theres another thread running that has simalar problems , well its sagging between the rafters 5/8s on 24 centers.

    You buy from the big box too?

      Read the 3rd paragraph above....

      The other thread you referred to - was that one that started about 1.5 months ago?  I think I remember it...

      1. Mooney | Aug 08, 2006 04:55am | #4

        I dont read so good . <G>

      Yes, as posted ventilation is continous from the soffit with perforated vinyl through to the ridge vent, which is continous along the ridge. 

      Incidently, what does buying from the big box mean?

        Incidently, what does buying from the big box mean?

        I thought thats what the other guy did , but between my memory and my reading , who knows? <G>

        So did you do it ?

        Actually the sheeting manufactor should stand behind it or at least the material since both jobs were man spec.

        Maybe that the insurance will have to replace it and get after them , I dunno.

        I ran some roofing a couple years ago that had definate patterens of two separate colors codes. They said tuff luck , we hate it for you . I said well, yes it is becuse yall are toast around here. It may have had different color codes but came in the same pallet.

        Years ago I finished a drywall job and you could sand it with your fingers . Scratch it easy with finger nails and leave gouges. The reps told me how "I" could fix it , so I had to.

        PPG stood behind some paint years ago and delivered replacement paint by carrier . Really impressive but they didnt pay any lost labor .

        My experiences havent been good .

        I hope better for you .

        Be interresting who made this sheeting and tell us . Where its made would be cool to know.

          o.s.b. from local lumber yard here in north east ga. Same supplier for over ten years, never a problem in the past. if I'm not mistaken it's a georgia pacific product.

          1. Mooney | Aug 08, 2006 05:51am | #13

            If you have a local lumber yard and GP in your corner it shouldnt be a problem once the shingles are stripped.

            Or am I getting ahead of my self?

            IM always making direct statements here so take no offense please.

            If I were the homeowner I wouldnt have it but IM not . We actually have to stand good here for three years over somthing like this legally . Many think its a year but its truly not . A homeowner had a air conditioneer go down and called the install guy but he didnt show up so he called another one . It needed a compressor that the unit said was a 5 ton 10 seer . Owner said nope , I upgraded to a 15 seer .He had a reciept that said it.  He called me the BI and told me the story. I called in the state inspector for the installer wasnt in the county. The point to the story is that its three years on defective equipment and illegal business to name only  two.

            So this seems to be defective material or faulty nailing . Mebbe water and heat. Cant think of anything else . I didnt think about the nailing either.

            I had plywood separate and get weak after 30 years . I replaced it this summer on a reroof. Its got soffit vents , two turbines and two gable vents . Still tryin to figure that one out . We do have extreme heat and humitity.

            I think if you leave it more of it will come up given time and that wont make you look good the second time . Mebbe Im wrong . Id be looking for some help on it if its available .

            I was going ahead with the repair as soon as schedule allows which will be pushed in the interest of good faith buisness ethics. I will be on sight to photograph the repairs once stripped to have in my corner. However, I suspect going after insurance will be more painful than just stripping and renailing.

            The entire roof is not working loose, only four areas on both sides of the roof, this was verified by visual inspection in the attic space. I'm hoping the repairs I make will be lasting. I was not looking necessarily for blame in the situation as both my roofing sub, and supplier have been with me for over ten years, however I am looking for what caused the problem.

            Someone else posted something about clipped head nails sinking too deep. I am positive I used full round head however the possibility of the nails sinking too deep is real.

            You mentioned something about forced air for vents. I'm curious about that as I am suspect that this roof being in direct sunshine (and I mean hot!), all summer that ventilation through mechanical means could possibly help. Like I mentioned previously, there is adequate ventiliation through the soffit, as outlined by code in our area, however, I am of the belief that intense heat is a contributor to the problem.

            Thank you for your post, every bit helps!

          3. Mooney | Aug 08, 2006 06:32am | #15

            I didnt put all that venting on it . I inherited it when I bought the house I use as a rental. However I did replace the turbines.

            I know that the tubines are sucking air from the path of least resisitence which is the gable vents probably. What I do like about it is that its in four different postions end>|......T........T........|<end.

            What I also imagine is that I have a cross flow in a breeze in the gables and also the tubines are spinning drawing heated air . That leaves whats actually happening to the air incomming into the soffit vents. I lighted a cigar I bought for the occaison and the soffit vents are drawing like a vacumn. Country boy approach. <G>

            Im also adding moisture in wet  conditions . The air conditioning bills are reasonable .

            That is absolutely the best strategy. Not only will it help you sleep at night, but you will also create a very impressed customer. It is not that often that people did with businesses that are not trying to fix blame on someone else rather than stepping up and taking responsibility. The customer doesn't care whose fault it is. They just want it fixed. They have had plenty of experience with businesses whose main activity after a sale is covering their *ss.

            Let us know your assessment of the problem when you figure it out.

        what does buying from the big box mean?

        Big box is slang for The Home Depot, or Lowes.

        As for your problem, I would guess clipped head framing nails over driven through the OSB.  Don't call me daughter.

        1. JordanBuilders | Aug 08, 2006 05:24am | #8

          Ii'm not convinced this can be ruled out. However, as I am generally on the roof making sure all starts and ends up square and in addition making sure the eight inch in the feild and 6 on the seams ends up as such I would suspect the overdriving would be the problem as opposed to not sufficient nailing.

          However, this is the first job I've ever had end up "curling" at the seams. Plus the walls are fine, just a problem on the roof.

          I appreciate your reply, you might be right on target. But, like i said, my habits have changed little in twenty years of doing this and I'm puzzled as to why now and not ever in the past?

          thanks for the reply.

      3. rez | Aug 08, 2006 05:15am | #7

        'big box' is a generic term for any large national chain such as Home Depot, Lowes and the like.

        Normally associated with questionable quality dealing with some common building supplies.

        Sometimes said to sell inferior components of lesser quality than some regular lumber yards or plumbing supply houses."The old Quaker Meeting house is almost 300 years old and as my sawzall made its way into the pegged ancient wood, a smell emerged that told me about dried, cracked things. The ancient Quakers sitting in the well worn pocket of their silence on the darkened pine benches were whispering something to me across the years.  Something about why I was here, why we're here.  Lord but it was hot. I reached in to clear anything out of what was the sill, nothing but the hardened mud, lime and sand mortar, dust and shadows."  -- Jer

    I don't have an answer to your problem, but I am curious about why you used 7/16" OSB.

    Are you allowed to use that in Ga.? Around here ( NJ ) inspectors want 5/8" OSB or CDX on roofs. I know code allows 1/2" for 16" OC, but the inspectors here don't like that.

    Maybe because of even the limited snow loads we get?

    Good luck on your problem.

    1. JordanBuilders | Aug 08, 2006 05:38am | #11

      whoops, my fault, 19/32" on the roof. good eye!

  3. Dave45 | Aug 08, 2006 05:48am | #12

    I'm no roofer, but I wonder if those 8d nails may be the problem.  Around here (San Jose, CA) the OSB sheathing is stapled instead of nailed. 

  4. Pierre1 | Aug 08, 2006 07:59am | #16

    Maybe the OSB sheets in the problem area were not spaced apart sufficiently, so those seams buckled when the sheets expanded.

     

    1. blue_eyed_devil | Aug 08, 2006 05:30pm | #21

      That would be my guess Pierre1.

      Sheet stock has to be layed with a gap to allow for expansion and contraction. A state like Georgia has hevy moist air and it will swell up the OSB in a significant way. There should have been 1/4" gaps on all the seams but most carpenters are ashamed of leaving gaps that large. Only the "hacks" will lay these types of roofs right!

        Gene_Davis | Aug 08, 2006 05:53pm | #22

        Ahh, would that the OSB makers would make those sheets at 95-3/4" instead of 96".

        Us hacks are only doing a few new roof decks per year, but we are aware of the need for those expansion gapolas.  We use clips between rafters or trusses, which yields some edgeways cleavage, but when we think "how can we end gap," our high-precision roof structure layouts always confound it. ;-)

        1. blue_eyed_devil | Aug 08, 2006 08:37pm | #25

          I'm satisfied with 96" sheets. I'm not so anal that I need the joints to be exactly on the center of the framing. If I can catch the support member by 1/4", I'm okay with that.

          So...the joint tends to start out on one side of the framing member and end up at the other side when the last sheet is layed on a normal house. It's no big deal..just gap it and go.

          "Ahh, would that the OSB makers would make those sheets at 95-3/4" instead of 96"."

          I'd like to order 50' x 4' lengths for my 48' house w/1' overhangs.  Or would expansion be a problem there too...

        well I'll be derned,,,, ol' blue!

        figured i'd get some expert advice from your corner!

        i'm starting to believe i need to adjust framing techniques,,, never had this prob in the past however your post along with others is the only logical reason i've heard and makes sense. just seems like if it were a very typical problem it would have reared it's ugly head many times in the past.

        got my long time roofer lined up to snatch some shingles and make repairs for me by first of this coming week, so until then i'm hoping the fix will be simple and painless.

        good to hear from ya blue, have enjoyed reafing your posts on here and learning new methods for a good many years from the likes of you and rhode island mike and a few others. figured you would have done retired by now! ;)

      1. Pierre1 | Aug 09, 2006 02:11am | #35

        Take a look at the APA mill stamps on the roof sheeting. If it says 'sized for spacing', the product is factory cut 1/8" shy of 8', to allow for a 1/8 expansion gap while keeping to your layout. That's the easiest product to sheet a roof with. Georgia-Pacific mills panels that way.

        If the above are not available in your area, the full 8' OSB panels ought to be trimmed if you're going to keep to your oc without pushing and pulling your top chords every which way. I guess you could trim every 2nd or 3rd panel and maintain sufficient contact with the top chord/rafter.

        Congrats on your ethical dealings with your customer.

          This is making a case for plywood if it comes back down to match .

          Tim

          1. blue_eyed_devil | Aug 09, 2006 05:22pm | #38

            I don't think this makes a case for plywood. Plywood has the same problems.

            Back in my apprentice days, we used to use two types of CDX ply, fir and yellow pine. Normally we'd get fir. Then, one day we got some yellow pine and we laid it like we normally did....no special effort to gap it. Big mistake!  but On the yellow pine jobs, we learned that we better make darn sure we spaced every joint. How did we learn that? We had to go back, strip shingles and cut expansion gaps on a few roofs.

            I've had inspectors check for gaps in the plywood. One time he wrote one of our jobs up for not having gaps. I guess he wanted me to run a saw through and gap them more than they were. One minor problem: the shingles get laid the next day after we frame and the frame inspection doesn't come till the rough mechanicals are done. My solution: I told the building inspector that I had laid the roof with gaps and that evidently the roof had already expanded and my gaps had done their job and not forced the roof ply up!

            He couldn't argue with that. I passed inspection.

            We do gap ply and I've not had any buckle, but our OSB is usually a decent grade and quality. I've seen some OSB products that make me think I'd need to leave a serious 1/4" gap everywhere instead of the casual 1/8" gap that we routinely do.

    The first and last time I put OSB on a roof I had similiar problems. My brother and I installed and backnailed it, then went home.Heavy dew overnite expanded it, popped the centers up a couple inches. Tried to nail it down with 12 commons, ended up ripping the sheets.

    I don't mind using it on sidewalls, but roofs I stay away from.I know this doesn't solve your problem, interested on what you find out after opening it up.

    Kudos for standing behind (above) your work.

      Hi. I just got in the office a for a minute and decided to check this forum for any moe feedback. Your story sounds exactly like what is happening to my roof.

      The puzzling thing however isI can't imagine if the roof was fine up until about a  month ago. Not sure how accurate that is, but The homeower had been on the roof himself working with the satellite or something and said it was fine then, ( at least he had not noticed any buckling).

      The roof has drip edge and metal tim coil tucked up under that on the eaves so I'm lost as to how moisture could get up under there. It does indeed sound like your situation, And, I have long been familiar wha dew can cause on o.s.b.

      Preciate your input, Incidently what are you running on roofs now, ply?

          I'm confused by all the varying descriptions here of the product used.
          From 7/16" to 19/32" and from OSB to CDX plyBut all of them need a good 1/8" gapping for expansion when installed and i don't know if your men allowed for that when they built it.
          If they didn't, they caused this.Anoither Q in my mind is whether there was a big wind storm that might have sucked the sheets up

            i made a mistake in my original post. it was 19/32" c.d.x. laid on 16" centered trusses.

            after reading what everyone else has posted i'm starting to believe the sheets could have been laid to tight. I don't typically lay the wheets with a gap, I normally opt for 16 centers whether stick framing or trusses, and butt'em tight and go.

             

             I've never had this problem arise in my years of doing this, even on my personal house however,,,, experience being the best teacher, i'm listening intently.

          i appreciate that.

          the clients are maing it even easier to do the right thing by being very patient and not freaking out. wish they were all that way.

          i once had a woman sue me for not cutting a fishing vacation short because a door lock was not installed on a sliding glass door in a walk out basement.

          i made her wait till i got back three days later and after installing the lock i came home and got served with a lawsuit over that stupid lock. now hows that for being impatient?

            She was quite patient -- waited until after you got the lock installed to serve you for the lawsuit.

            So let me get this straight:

            You left a woman with no way to lock her door at night while she was asleep or while she was away?  Did you fasten it shut, or could an unexpected guest make a surprise apperance while she was in the shower?

            Maybe I'm off base here, but from what I've read so far you needed less of a lawsuit and more of a swift hard kick in the nuts for being an insensitive jerk.Rebuilding my home in Cypress, CA

            My girlfreind who set this account up appreciates you posting her file.

            That way, the gentleman who made the inappropriate comments about the swift kick can see who he might offend.

            Thankyou for stepping up.

            AAAAHHH!  That explains alot!  From what I read I thought it might be a remodel or addition to a lived in structure - not new construction.  My bad.

            Sorry, I did not read your profile.  If I had know you were female when I initially posted my comment, I would have written "crotch" instead of "nuts". 

            As for kicking, being the Manly Man that I am, or at least studying to be, I am bound to use the method described in the attachment.

        WE run 1/2' or 5/8 plywood mostly.

        Four years ago I did a roof repair for a builder we work for. Middle of winter, ice storm covers newly sheeted roof. Roofer shows up, papers it and roofs it. Six months later builder asks me to accompany customer service person for an opinion on roof problem.

        Second row from top is arched up 3 inches, entire width of house on both sides. Never seen anything like it before. My buddy and I set staging, and strip roofing and paper. There is no space between sheathing, so the sheathing had no place to go but up.

        We ended stripping shingles, and cutting the plywood out and installing new plywood.Usually when a builder calls me to do a repair, I'm the last resort.I actually like doing repairs like this , something different.

    I've certainly seen plywood that has set too long in a poorly-supported pile and developed a "belly".

    In this case it may be that the CDX has swollen, or that the rafters have shrunk. Under the odd weather conditions recently I'd guess it could be either.

    Note that sheathing spacing isn't that important side-to-side, as the rafters will spread apart fairly easily. The critical spacing is between vertically-adjacent sheets, since the rafters don't stretch very well. Usually, if the sheets are T&G, there are little bumps left on the tongue side every foot or so to maintain the proper spacing, so long as you don't over-drive things mating them together.

    If I had my druthers (as someone who has had to nurse old roofs along) roof sheathing would be in 24x96 pieces, or whatever works out well for shingle pitch. Would spread the expansion out over more joints, reducing shingle stress.

    1. JordanBuilders | Aug 08, 2006 11:24pm | #31

      Before the suggestions of spacing were posted, i had originally thought that ventilation, or possibly moisture were the problem.

      the roof is tight, as in no leaks so I thought perhaps moist air rising through the soffits, and passing along the underside of the roof system could have swollen the sheets cuasing the buckling.

      I'm no expert on ventilation or theory behind it, I subscribe to the methods i learned from tose who taught me the craft and until now have had no reason to question the matter. this roof was laid in the same fashion as all others, and should have acted accordingly, stayed where i put it.

      i've heard in the past that one should allow an 1/8 inch gap and i'm sure it states it on the sheets, however unless i use clips which i've thought was unnessasary with 16 " centers, then i've never seen the reason to .

      i'm going to do it for now on, thats for dern sure, however like i've said before, it's never been the least of problems. thas what befuzzled the fool out of me to begin with. i've built a lot of homes predominately foundations and framing and have never encountered a callback on plywood curling up on the edges,,,, strangest dern thing i have ever seen!

          7. rez | Aug 24, 2006 05:54am | #55

            Well, I meant the shotgun for the BI that would have shutoff my water but since I talk to you some on here I'd give you a running start of say 25yards before I'd start blowin' holes upyerazz!

      Hi,

       

      On the board you can see all of the opinions.

      Off the board they are just as varied.

      I had my supplier, a building inspector, a plywood rep, and a couple of roofers with whom Ive had great success over the years pay a visit. I also picked up an onion from one of my former pupils who is a crecker jack framer and I wanted to hear his take on it. 

      All opinions point to expansion.

      I normally run o.s.b. on trussed or stick framed roofs that are framed 16" o.c.  and this time opted to run the 19/32" ply thinking it was a better product as it was recommended to me.

      I'm sure that it is a better or maybe a stronger product, but it's tendency to swell under nromal weather has caused me to believe I need to either adopt Blues's method of gapping, the edge seams, or perhaps just go back to o.s.b. on the roofs for which i've had no problem in the past.

      The solution for me has been to replace three sheets of plywood and spot repair a couple of places by placing blocking between the trusses and runni g screws through the sheeting and into the blocking to flatten out a couple of buckled spots.

      This has been an adventure,,, and I believe I have nailed the problem,,,,, an I also hope the post might help someone else on here who encounters something similiar

      This forum was probably the best idea since the framing square in that it promotes sharing of information from all over the place. I appreciate the heck out of everyone for their help.

    We use staples on all the roofs we do,no problems, we are located in Southern Oregon, fairly decent weather year around so that might make a difference.

    1. Piffin | Aug 24, 2006 06:35pm | #69

      Staples are so bad that they are not even accepted in some jurisdictions

      1. Ricker | Aug 25, 2006 04:42am | #79

        Maybe those jurisdictions should take a second look, we use staples on our sub-siding, also. Seems like the only time we have a problem is if someone missed a rafter or a stud.

        1. Piffin | Aug 25, 2006 10:39pm | #80

          or if it is driven too deep
          or if shear strength is desireableIt is easy to miss a stud with one of the shanks.

            I will say I would have no problem using 8's as long as they are ring shanks

          2. Stilletto | Aug 26, 2006 02:04pm | #84

            That's all I use on my frames.  Ring shank 8's for decking and sheathing. Full round heads in a coil nailer.

            Better make sure everything is where it is supposed to be before you sheet it,  you'll pull the heads off before you pull the nail out.  I'm only half as dumb as I look.    

             

          3. Piffin | Aug 27, 2006 07:23pm | #85

            That is how I nailed the sheathing on a roof just yesterday.

          never took the time to learn the game of golf, i probably am missing out, however it is on my to do list to have a go at one of those giant flounder yall call halibuts out where you are at.

          my girlfreind grew up in a town called newberg and her parents blew me away with the photos of the fish the caught out there.

          i beleive if and when i make it out there i'll be setting up camp for good!

           

          take care.
