Leaky Porch Roof and other porch roof issues

I have an aluminum screened porch with an aluminum roof (see the photo of the porch roof here - http://picasaweb.google.com/dbanghart/DoItYourSelfPhotos/photo#5055686816745439650)

I am guessing that the porch roof is leaking where it meets the house roof. I looked under the edge of the house roof, intending to caulk everything, and noticed there are foam blocks butting up against the eaves/fasciaboard/??? on top of the porch roof and underneath the house roof.

Can I caulk around the foam blocks? Could I fill the whole space with instant foam? What caulk should I use? How best should I deal with the leaks?

Also, even though I just moved into the house on March 1, I am tired of cleaning off the leaves in the gutter. I was thinking of buying gutter screens, but as you can see from the photos, the far gutter edge is higher than the bottom of the roof. So the leaves will not get washed off the roof.

3rd. How do I reinforce the porch and roof to better deal with Florida hurricanes

As usual, i couldn't get the pics to come up. But don't rely on caulking -- FLASH the joint. Lay the flashing over the top of the porch roof and work it under the roof of the house. You have to get it far enough back under the house roof so that the water running off of the house roof cannot get under it. Get it AT LEAST 6" under the house roof edge.

Mike, I did the same thing. I included the parentheses at the end and it didn't come up. Leave it off, and it will.
DB33549, from what I see, you may have more fascia damage than meets the eye, unless the original installer flashed, like Lefty said. If you remove the lower gutter, you will have a constant runoff when it rains, but if you leave it, you will gather leaves, so Catch-22.
The type roof you have, won't withstand a hurricane, no matter what you do to reinforce it. Hurricane ties from the roof joisting to the vertical members will help keep the roof tied to the main structure, but all you have is a glorified parachute that will lift off. I note, too, the panels are held down with nails, is that correct? I also only note only one run of fasteners, so I question that, too. I would opt for 1 1/2" hex head screws with neoprene washers, especially when they are installed on the "flat" like yours are. Nails were made for installation on the ridge, and offer minimal pull out strength.
