the roof top a cored fiberglass sandwich. If you stand on it does it flex? If it doesn't flex then it is still well laminated and you can just reglass the seam that has split. Fiberglass does expand/contract with temperature and depending upon how Hatteras finished the edge originally may have not been strong enough. If the roof flexes then it has delaminated from the core.
P.S. Dan, I like your George Orwell quote. It is a main stay in Special Ops. Here is poem writen by a soldier from the parachute regiment in regards to rough men.
Rough men
There's a character trait that's decided by fate
Comes (sadly) to many, far too faint, far too late.
They won't face the aggressor, stand up to his ire
They have not the will to fight his fire with fire.
So they bend over backwards to see all sides as fair,
Till they're faced with dragon breath fire in their hair.
Like our brethren in France, who'd know better than we,
Yet seem never to learn, seem doomed never to see.
Yes, it seems there are some who're determined by fate,
To possess not the courage to step up to the plate,
Who shrink from all threat because nothing's worth war.
But how can they know lest they've been there before?
Thank God some have courage, the will, yes, the grace,
To stand for the shirkers, stand strong in their place.
Thank God we have stalwarts who'll stand for us all,
Who will rise to the challenge at their nation's call.
The faint-hearted, who fear, whose reaction is flight,
Have no comprehension of those who will fight.
To hide their own trepidation they attempt to demean
The rough men, who defend them, as barbaric, obscene.
Yet these rough men stand ready, hard weapons to hand,
To put placaters behind them, draw a line in the sand,
To preserve for the peaceniks what they won't defend,
So their own unearned freedom won't perish, won't end.
To appeasers, rough men are coarse government tools.
To rough men, appeasers are dumb delusional fools.

It seems that nothing ever changes with the appeasers of the world, and I thank God that we still have men that have the courage to make the stand.
