ASTM D 3161 UL 2390 ASTM 6381class H ASTMD7158

These are codes for 110 + wind uplift . They have been assigned to 3 tab shingles . First I have heard of it . Anyone have any info about this and what does it mean exactly ? I never knew 3 tab shingles came with those type of wind ratings . " i dunno "

Robby What I was getting at : Contractors would insist that the manufacturers warranty was the bench mark for the wind uplift . Consequently the warranty was used to up sell homeowners to a 30yr shingle . A supplement would be filed with the insurance company . At this point the claim is assigned to a supplement adjuster . Most supplement adjuster are inside working with estimating programs . State and or local high wind uplift was sited for upgrade , The shingles have been tested for the high wind and passed .Argument over . Three tabs are except able

That's not what he was getting at, Robby. Every one of the shingles I saw on that Texas list passed at 130 mph, three-tabs included.

Is your argument that insurance adjusters will not pay out for product blowing off that has been tested by ASTM standards at 110mph? If this is to be the case, then adjusters will catigorized the roof as workmanship related? No one should be suggesting a three tab where 110mph sustained winds anyways!

After more research and conversations it is almost official . The stormers and or roofing contractors trying to upgrade homeowners and insurance companies to a dimensional type roof shingle because of the wind uplift , " sorry." Especially in Colorado and Georgia . Most adjuster are now up to speed ( pun intended )on the wind uplift standards FWIW . It may still work to some extent . I may be called in to give a seminar . B) :laugh: :laugh: B) :woohoo: It also is meant to give FYI and update/ on current conditions .

egg Said: Im wondering why you believe this warrants a separate thread from the one you just started CIAK. Perhaps it would be helpful if you gave us a little background on where and under what circumstances you encountered this issue and what relevance it has for you. ...have been assigned... means what exactly? That there are shingles that have qualified? That three-tab shingles must now meet this standard? Whats the context?

ASTM does not do codes. It does testing standards. Code may require products to meet certain testing standards. Meeting a testing standard does not mean a manuf. is required to warrantee its product in any specific way it chooses not to. I can meet a 200mph test standard but only offer you a 100 mph warrantee. (see the Malarkey quote in the other thread: 110 vs. 100) Conversely, even though it would no doubt catch up with me I could offer you a 200 mile warrantee (my prerogative) yet not meet a 100 mph testing standard (code.) Code does not involve itself with the warrantee. It specifies that a product must meet a testing standard. ASTM does not involve itself with code. It establishes testing standards. Related but different, if you follow.
