FL Hurricane zone: PVC or Andersen Impact windows?

I met with another roofing contractor and asked him to give me a bid to repair the copper roof. He wants to replace and not repair. He says that his company cannot grant a warranty on the repair, only on replacement of the roof. He will write up an offer. Uses satellite imagery to determine the square footage, and will have an accurate measurement of the roof area.

Also we continued the search for new windows. We received a quote for white PVC frames and new doors, for $26,496 including taxes and permit. This is for impact-rated. Non-impact rated windows and fiberglass doors are $21,321. Just a word on impact vs non-impact, and turtle glass: I have been doing research on this topic, since the price point is so high and a mistake will be very expensive. Since the house is located on the barrier island, it is in the highest hurricane wind zone. Therefore, we *must* either put in impact resistant windows, or add external shutters. We could also put in impact windows up high, and shutters down low. That way, in the event of a hurricane, we wouldn't be scrambling to climb ladders to shutter the upper story windows.

I've come to the conclusion that excellent windows should last a very long time, and we'd be better off to spend a bit more on them, rather than cut corners, especially at this price point. Additionally, the salt water causes corrosion in this locale, whereas we don't have that issue at our other properties, which are all inland a few miles. This rules out aluminum, too, which will show corrosion in any event.

Andersen pricing is still pending.
