Is there a tinted protective dome that will just cover the whole skylight. Mine are flat glass and I am concerned about large hail. They rise 5" above the roof,
Laminated safety glass will withstand some serious impacts. Look to the manufacturer to replace the skylight top if the specs for the glass are acceptable.
Another option is to get 1/4" plastic and rig a frame for it to slide into, over the current glass.
We just had a hail storm on Long Island where golfball sized hail came down and did some serious damage. Local body shops and glass dealers have cars lined up with broken windows and pock marked hoods, roofs and trunks.
"They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety."
B. Franklin 1759
