soffit vent screen replacement
 

house in s.florida, roof ledge(also made of concrete/stucco over wiremesh) over the
concrete block walls has these superfine metal screens and under the metal screen one
can see (from looking up) the coarse metal wire frame which is stuccoed except the
openings of the screens

over the years (house is 40+ years), these screens have collected debris from the
attic and while I can point a blower nozzle at the screens, would like to consider
cutting these out and replacing all of them but don't know the best method or
materials needed.

is there some standard screen replacement material available at home depot or lowes?

is this simply a matter of taking my bosch metal cutting blade and removing old
screens, section of the metal wireframe, vacuuming inside the hole and inserting a new
matched-to-size metal screen (how is this attached?) or something else?

reason I ask is to improve the air flow from soffit vents into the attic, ridge
mushroom turbines are in place there which would likely passively vent this space
better if the soffits were breathing better?
