ᐅ Attic space - tongue-and-groove boards - installation tips?

Hey,

the roof truss might be installed next week or the week after. On that occasion, I want to use the already available crane to lift the tongue-and-groove boards into place. Now I’m wondering which length would be best to order so that they fit optimally.

The general contractor mentions in his information that the attic floor should only be made walkable after two heating periods due to residual moisture in the wood and the risk of mold. However, he gives his approval (or recommendation) if you want to start work early on a partial area under the ridge, with a width of 100cm (40 inches). The attic measures 2.83m (9 feet 3 inches) by 9m (29 feet 6 inches). I was thinking of ordering 3-meter (10-foot) long boards and laying them from eaves to eaves. With the 100cm (40 inches) recommendation, that would leave a free strip to the eaves on each side that would eventually need to be covered. Or would it be better to lay the boards from gable to gable to better accommodate the 100cm (40 inches) area?

I’m a bit unsure about this...

Thanks for any ideas!

If you want to install the decking boards prematurely, it is advantageous if the boards are fastened at only one end and initially just rest loose at the other end. It is also not necessary to lay them tightly jointed side by side. They will only be placed in the central part of the roof structure anyway. This allows for good movement and proper air circulation.

Best regards,

Hey,

I’d appreciate your advice on how to solve the following "problem."

The rough-sawn boards were delivered and are currently stacked in front of the house (I covered them because rain is expected in the next few days). The carpenters didn’t have the supplier lift the material onto the collar beams, probably because the boards were bundled together and the weight wouldn’t have been evenly distributed. I ordered lengths of 5.10 meters (16 feet 9 inches) and 4.50 meters (14 feet 9 inches).

On Monday/Tuesday, the interior walls and gable ends will be built on the top floor. The roofer is scheduled to come the following week.
Now I’m thinking about how to get the boards onto the collar beams in the days before the roofer arrives (good weather is forecast since the roof will be open).

Maybe someone has faced a similar situation and didn’t have short planks to pass the boards up?
The scaffolding on the gable sides is in place and seems to reach as high as the collar beam (at least by feel), but the gable itself is closed.

My current idea is to feed the boards from outside over the scaffolding into the top floor, then thread them through the beams further up onto the collar beam.

Perhaps someone has a clever tip?

Thanks!
