It consists of a 5x5 sloped side at the back and a 4x5 straight side in front, with a satellite dish on the zombie side and a chimney on the player's side, where the zombies enter to get inside the player's house.
Graze the Roof, the music used throughout the Roof levels
Environment modifiers
Repeater cannot shoot peas over the angle (the pea has been blocked)
Straight shooting plants (Peashooters, Starfruits, etc.) will not be able to hit zombies if planted on the sloping side (although they can fire over the edge when planted on the first sloped column next to the straight columns), so the player will need to use lobbed-shot plants for this stage (the player can use Fume-shrooms too, but the need of waking them up using Coffee Bean and their short-range may prevent the player from using them much).
Plants also need Flower Pots to place plants on the roof due to the fact that the roof is not made of soil thus making the roof's surface unplantable (same goes for its night counterpart). Because it takes place during the day, sun falls from the sky during this stage, and mushrooms fall asleep.
There are no Lawn Mowers, so until Roof Cleaners are purchased from Crazy Dave, the player's last line of defense is their leftmost plants.
This area also has "ambush zombies", which are actually Zombies (or Conehead Zombies and Buckethead Zombies) that are dropped by Bungee Zombies onto the roof, possibly into the player's defenses, although they can be repulsed by Umbrella Leaves. This is similar to the zombies that surface from the Pool and the zombies that come out of graves. Overall, this is the hardest area of the game to overcome.
Plants vs. Zombies: Endless Edition exclusive (Archived content)(China only)
In addition to the pre-existing nine stages, there were three bonus stages exclusive to Plants vs. Zombies: Endless Edition. They all had an objective to complete. They required specific fully grown plants in the Zen Garden or 20 diamonds.
Crazy Dave and Cabbage-pult do not know how the zombies got on the roof in the first place, but at the beginning of roof levels, the player can see a ladder at the right that may have helped them.
