Pssshhh.. I was born for the Zombie Apocalypse.. I've been training and preparing myself for it for the last 15+ years. Make a few looting trips to stores less than a mile away from my house at the onset, stock up on ***I'll need, then go in the attic and wait it out a bit.. You don't wanna be out there running around while everyone else is panicking.. Gotta wait til it dies down so you can move quietly to find a more secure place to call 'home'.
Our attic was converted into a bedroom long before I ever moved here, and the stairs are retractable, they'd be easy enough to defend if zombies were smart enough to pull down the stairs and climb, and if even that proved too much, they could be easily removed completely.
Our house is also old, which means it has those traditional vents on the side of the house just below the roof.. So if push came to shove, we could make a quick escape to the roof.
