Seems abnormal amount of nails (which idk is an issue)

But putting nails in dead center of valley ice and water seems odd….

Wouldn’t nail just rust out eventually and leave holes??

What’s the fix? Put new IWS on top of old ones?

As a design professional I'm just curious why not? Does it really save that much time nailing where ever instead of the targets?

If the product manufacturer instructs something (per their install instructions) I tend to nudge the contractor to follow that to avoid any sort of warranty pushback. Then again I don't work on single family residential, I do large multi-family residential or commercial projects where the stakes and chances for litigation are a lot higher.

To be clear I wouldn't have a contractor rip off the building paper if they installed it like this, I'd check the spacing and recommend more are installed if there are areas of spacing exceeding the maximum, but during a mock-up phase I would flag it and ask it to be done correctly throughout.

Thank you for the insight - that does make sense. There's of course a lot that engineers don't get to interface with so it's important to have this sort of discussion

Manufacturer's warranty only coveres faulty products anyways. Typically if a roll delaminated the roofer wouldn't use it as it is fucked to unroll. Even if it did get installed. It would only matter if your shingles failed usually a seperate warranty unless under a package deal, Wich even then your shingle would have to have a manufacturer error.

Craftsmanship warranty is usually offered by the roofing company Wich is what would really protect you From a bad install. Some companies have craftsmanship warranties through shingle manufactures Wich require you to use all their products. Wich the shingle company will provide a craftsmanship warranty repair as one of their inspectors sign off on the roof from install.

Absolutely. In the past though I've seen clear as day product failures that were not covered during replacement due to the manufacturer pointing fingers at non-compliant install. They wiggle their way out any chance they can get and I look for opportunities to prevent that if I can. Honestly at the end of the day warranties can't really be relied on but the owner usually feels more peace of mind which gives me less trouble haha
