When it comes to constructing a platform, it is essential to understand the gap between deck joist hangers. Generally, the space between the joists should be 16 inches in the center. However, this may vary depending on the roofing material installed at a 45-degree angle to the path of the joists. In such cases, the gap should be 12 inches in the center.
Additionally, blocks should be placed every 12 or 16 inches between the outer joists to support the platform placed parallel to the joists. At times, terrace frames are designed in such a way that the staggered line of blocks falls below a deck board to protect them from moisture and make them invisible from above. To ensure that the ends of the platform are supported, it may be necessary to construct a support frame by means of a lock. Each roofboard manufacturer submits their roofing material to extensive independent tests to find the correct spacing between the joists. The right choice depends on the material requirements of the roof, the span of the beam, the overhangs and how strong you want the platform to be.
To make sure that your project is completed in accordance with all local codes and meets the highest standards, it is important to correctly plan the spans of the joists and their spacing. This will also make it much easier and faster to obtain construction permits.

The minimum joist size used in roof construction depends on distance between support points and species and grade of treated wood used for joists. Platform joists have different maximum wingspan lengths depending on size, spacing and frame material with which you are creating your platform.
