O/C Duration shingles

Hello out there,

Is anyone else starting to come up with handfuls of rusty nails in the O/C Duration SureNail strip? I've come across a handful of roofs lately with this problem - one under 4/12 and most of them over 4/12 but less than 7/12. Nailing seems to be properly located, and I'm finding this in wide-open field areas of the roof. I can't find any installation faults on any of the areas inspected. Seems to me this will be problematic as these are all under 2 years old.

Thanks in advance for sharing your experiences!>>>

Yes i am not real familiar with the Sure nail strip and i was thinking 3 tabs i forget the sealant is on the back side of the shingle with these and seals in the sure nail strip where the nails should be so some could be above and some below -- I did find the application instructions on mansard and steep slope they show fasteners below the the sealant

Looks to me like the nails are installed above the sealant----- at least according to a Menard's circular I just got in the mail :P>>>

I Thought the nails were supposed to be placed below the tar strip -- at least that is what i have read on every bundle i have read -- Not quite sure as to The new sure nail strip by OC have not installed any since the change.>>>

You are right John, OC Jim just kept on brushing that off as a non-issue.

Yes Ed,I remember us(aaron,you,and I) getting reamed for continually asking about that exact percieved problem ,We kept asking for the answer,they kept dancing,we kept asking,and then were told we had been unfair to ask for an answer to that question,seems he said "Get out from behind that desk,Put on a couple hundred square,and see for yourself" Where`s OCJim when the calls start ???? I told their guy then without an appropriate answer,he could forget about any business from my company>>>

I'm in FL also - same nails everyone in town uses, same everything. And roofdoc is right - water gets in the butt-joints and runs across this lower, smooth "surenail" line and just sits there trapped. I'm finding some nail heads almost completely rusted off at the 2 year mark.

I've just called in my first claim. I'm concerned about the 100+ roofs of Duration I put on when all of Orlando wanted that new 110mph shingle before CTD and GAF upped their warranties from 80mph.

I'll let you all know how it goes (hoping for a miracle).>>>

When they first came out with self sealing shingles, they used to put a continious strip on the shingle and the same thing happened. Bird and sons started to use dots of sealant and the others also had their variations of the strip of sealant and then a gap. It traps the water above the strip and holds it there. I don't used OS's so I don't know for sure if that is what you are talking about.>>>

That was the majority voiced concern when they first came out with that solid continuous sealant line.

Now, it seems as if those concerns are warranted.

I haven't installed an Owens Corning Roof since around 1998, with the one exception of doing my Dad's roof on his home in Wisconsin, because he is a cheap SOB and wouldn't pay the extra $2.00 per square for a better quality, but at least they were OakRidge instead of Durations, and that is primarily because OC takes the marketing point of supplying the Big Box at Lowes.

We've installed a few of these. Certainteed products are the shingle of choice for us, but sometimes color choices don't work. I'll have to stop back and take a look see . . .>>>

Did not specify he just blamed it on the nail. If your not familiar with the duration line they have what they call a sure nail strip. The problem seems to be the smooth sure nail strip is lower than the granular edge and the water dams up there. It does not sound like it would be enough to rust a nail but it is. I'm in Fl. I also saved a shingle wrapper that has not been changed yet, all they say about the nail is it has to be 9 or 10 gauge nothing else. I did hear they are changing the wrappers, so if you don't keep an old one you don't have a leg to stand on.>>>

I've always shied away from O/C's so I have no experience. Are you saying that the heads are rusting? Sounds odd, how is the moisture getting to them? What part of the country are you in? Roofdoc- What nails was he told he should be using?>>>

Yes its getting reported alot around my area. One of our local roofers called OC and the tech guy came out and inspected the roof with the contractor and the home owner. He told the contractor in front of the HO the wrong nails were used and that was the problem, THEN HE LEFT. I only used OC now I only use GAF. Its scary for me I have hundreds of sq. out there, and OC is gunna leave me holding the bag from what I hear.>>>
