In our FL house the patio/pool area is enclosed by screened-in lanai with peaked roof that is probably 20ft high or more at peak...
Built of aluminum in sections so if screen sections tear they can be replaced individually.
Our screening is in good shape but when the previous owners had this new frame done the contractors did not use stainless steel screws to join the sections.
Our pool guy has told us there is rust coming into the pool via rain water.
Rust is very difficult to get out apparently.
He recommended having some one either replace all the screws with stainless or use something to coat the screws so rust can't leach into the pool or decking...

Questions:
Anyone have similar problem?
How did you handle it?

There is always possibility hurricane or high storm winds might damage screening. Seems more practical to just seal screws vs replace and probably lot less expensive--but haven't gotten bid on ether job.

Second--
Once we spend longer periods of time in this vacation home, we will bring our dog and cat. Our cat is 13 and starting to show his age but he ia also used to roaming outside when he wants to...For several,reasons, he can't do that in Fl like here in TX. We are afraid he will try to push out through the screening though or try to climb it to get to the real outside -- not good for him or the screen.
We are considering using lattice sections on the inside of the lanai to keep him off the screen. The normal size sections laid sideways should be right dimensions to cover bottom 3 or 4 feet of screen...
Plastic lattice apparently expands in the heat so don't think it is viable.

But we aren't sure if wood lattice would hold up and not need to be treated/replaced every year to keep,it looking attractive...
Anyone have experience with it?
We want something easy and inexpensive to install that will allow air flow -- not anything solid...

Appreciate input...
