The screens on porches are the responsibility of owners. The screen includes the 2x4 wood frame that the screen is attached to - the perimeter and cross pieces.
A Renovation Questionnaire should be completed for screen/frame replacement since it is visible from the exterior. The wood frame pattern may be changed with prior approval. Some owners have added balusters and railings. Others have placed the screen on the outside to make cleaning of the frame easier.
The 2x4 wood frame has cut-outs at the bottom to allow water to drain off the edge of the porch floor. When replacing the frame, the cut-outs must be maintained.
The floor on screen porches is covered with a rubber membrane to keep water from dripping onto the unit below. The rubber membrane must not be damaged during flooring or carpet installation.
