Duration Sure-Nail Strip (cellophane)

I buy the EG 1" for felting. That's what they're made for. HDD and copper are made for roofing. I won't use SS becasue they're too hard and brittle. Dennis from Roofer's Review posted a pic some time back of a 1700's copper roof nail holding a stone roof on. The nail had turned green and the stone above it had rubbed hte head off. Otherwise, it was good for anohter 100+ years.

I will not allow myself to even think of using zinc-chromate on anything. To defend against the kind of problem mentioned here I have also increased my set-back and stopped doing any recovers. I haven't installed any shingles with a continuous seal strip. I may be wrong, but I don't think the OC shingles I have seen around here have a continuous strip (any longer?)

I am also not buying some recent nonsense about eliminating granules in the nail zones so the bundles will palletize without distortion. It was never a problem before. If we're shooting air-nails through a cold, humped shingle, we need to stop doing that.

Tinner,I think you are one of the very few that uses HD nails. We use EG's and haven't had any problems on 4/12 or greater slopes. I have noticed the decreased quality of EG nails like others have mentioned. And yes, the cellophane nail strip would hold water.

I have noticed that everything in the shingle industry has gone up in cost over the last few years while significantly decreasing in quality. Nails were getting even crappier back when I was shingling over en years ago. The price started to go up then suddenly we had these cheaper nails and they instantly became the new standard. In my experience, the heads pop off during install and in fl, any nails left on the roof were rusty the next day! I have been arguing against pneumatic fasteners for years now. Yes because they encourage less than proper installations but mostly because its really hard to get quility fasteners that are connected. I'm not aware of any hot dipped connected fastners. Electro galvanized should not be used even on a modern shingle roof. I use stainless steel hand nails and have even seen the quality decrease in those recently. I used to buy from swan secure and the price started going up and up. Suddenly, as if overnight, all of my suppliers swiched to simpson strong tie and the price went lower than before. BUT, I have noticed the heads seperating on the nails and the heads spinning off on the screws. Ill happily pay more for proper fastners as most of our roofing relies on mechanical fastners. All of my roofing relies on mechanical fastners. No electro galvanized and no pneumatic nailers on my job sites!

My point is with all of the ill intent, cheap compromises, decreasing quality and lack of sense in todays fiberglass/asphalt market makes it hard to know which direction to point the finger at when failures happen. The only universal thing that one SHOULD expect is the complete lack of resposibility from all parties involved. Roofing has been being done for thousands of years. Those of you installing these experimental materials are experimenting yourselves. Thanks for sharing the results of one of your experiments.

Bill Said: Leak due to nail heads rusting off.

This is the first I've heard of HDD roof nails rusting away. I'd contact Maze or Grip-Rite and raise a fuss. You must have gotten a bad batch since I'm not having any issues with the ones I've been buying.

Leak due to nail heads rusting off.

Whats the initial problem that gets your attention? Blowoff's due to failed nails or a leak?

Old School is correct, I have been dealing wqith this problem for about 10 years now.

What I said originally. The water can get in at the joints of the shingles, but the continous sealant strip won't let it out. They did this in the original self sealing shingles in the mid 60's and "fixed" it about 2 years later when they had the same problem. a new set of engineers now and the same problems I wonder why?

Well O/C flew into FL from Ohio to view my rusty nails and of course blamed the nails. My opinion is that it is like the firing pin blaming the bullet. If the water was not being trapped, the nails would not rust! I believe the redesigning is an acknowledgement of their failed engineering on the old Duration. Hopefully, I do not end up in the middle of a lawsuit because of this BS!

I think that the biggest problem with that system is that they used a continous strip of sealant instead of spotting it. It is not the 'condensation' but the fact that the water gets in at the joints in the shingles and can't get out. I saw the same thing in the mid 60's when they first came out with the self sealing shingles and they had the same problems. A new set of engineers and they have to re-learn what we have known from the past.

There is going to be a whole large can of "whoopass" coming from this fiasco, and they would not listen. they will have to pay.

We put them on once. Quickly realized they were junk.

The new strip looks better. My guys like it. We've put it once.
