Essentially, you fit floor boards to the ceiling joists. The more common option is to use 4' by 2' chipboard tongue and groove floorboards, using screws and wood glue on the joints. This will stop creaking.
Better put them in. Something has to hold the roof or roof panels up and prevent them from holding water.
When Ideal loft ladders are opened, they extend from the floor to the roof; however, when they are closed, they neatly slide or fold into the attic. The attic ladder hatch is firmly fastened to the ceiling joists, ensuring its longevity.
In construction, a joist is a horizontal piece that runs from wall to wall, wall to beam or beam to beam. A joist is essentially considered to be one of the most supporting pieces towards the structural aspect. It focuses in on supporting beams and other pieces in the floor, ceiling and roof.

A cantilever deck is a deck that is suspended by joists that stick out of the structure. The distance the deck sticks out of the structure is one-third the total length of the cantilever beams that enter the structure. Usually these beams are bolted to (or sistered) to the second story floor joists or the roof trusses. Onto these beams are attached the floorboards that make the surface of the deck. And onto those the railings are attached. Hope that helps :-)
L.V.L or laminated veneer lumber is used mainly in house framing as Floor joists, Lintels and as roof beams.It has also been used for scaffolding and various other uses, but not as commonly.
Non load bearing walls are walls that the weight of the roof is not supported on. Any wall that runs parallel will roof joists will be non load bearing.
From AS 1684.4 Residential Timber Framing Code 2.6.4.1 Coupled roof Pitched roof construction with a roof slope not less than 10°, with ceiling joists and collar ties fixed to opposing common rafter pairs and a ridgeboard at the apex of the roof (see Figure 7.1). A coupled roof system may include some area where it is not possible to fix ceiling joists or collar ties to all rafters, e.g., hip ends or parts of T- or L-shaped house. 2.6.4.2 Non-coupled roof A pitched roof that is not a coupled roof and includes cathedral roofs and roofs constructed using ridge and intermediate beams.
Since a demising wall typically separates tenants it should go from the floor to the roof, or from the floor to the floor structure above leaving no openings for sound, smoke or fire passage. Each local code is different on exactly what type of construction is required for this wall so it's best to research the code before any decisions are made.
