Temporary Supports? Options in attic.


Before I bought my home, they said that the roof had recently been replaced from tree damage. There are some supports that i can move with by bare hands without much effort. Can you guys shed any light on if they belong or if they can be removed or do i need to have a structural engineer in to relocate them?

If they are not needed or i can re-engineer the supports, i can create some more usable attic space. The rafters are 2X6, 2ft on center. It's about 8 feet from the attic floor to the ridge.

I'm not the pro here.... just going by what I see.

The rafters are on 24" centers. Do you know how thick the chipboard roof sheathing is ?

It looks like those supports are transferring the additional roof load to the center of the ceiling. Depending on the span of the ceiling rafters that may not be a good thing.

Usually you would use collar ties to help the roof support the weight.

The pros will stop by and comment.

Also not a pro, but what I see doesn't look like it was engineered from the start. Those verticals are just fastened into the rafters as opposed to being braced underneath them. And as PJ said, you also need to know what is below that makeshift support. If they replaced the roof, were the supports added to shore up damaged rafters?

I'm a pro, but not an engineer. IMO these braces are not temporary or have anything to do with roof being repaired.
These horizontal members and angled supports are called purlins. Since your roof is stick framed and you have 24" on center rafters, the roof deck needs additional support.

You can confirm this. These angled supports should be bearing directly above an interior wall, and angled to support roof rafters. They should not be removed.

It's also highly likely that attic was never intended for storage.
What size and free span are the floor joist.

2x6 on 24" centers doesn't sound to me like it would hold much.
