A roof solution at last?

Rather than make NEW trusses and NEW roof pieces, I opted to simply cover existing roof pieces and trusses. Here's a picture of a thatched roof in a Thoumont's truss:

I didn't modify the truss at all. It's standard TLX, which has the following things going for it:

1) If you've made any trusses already, you won't have to redo them.
2) If you've never made them before, you can follow the TLX instructions.
3) They're fully textured inside and out, and are really sturdy.

I also didn't modify the roof at all. Well, sort of. What I've done is created a rectangular piece that covers the existing roof as well as the truss. Here's a picture of the roof, upside-down:

So, it's a TLX roof that I glued an extra piece to. This has a couple things going for it:

1) You can continue to use your roofs as-is!
2) You can upgrade your existing roofs very easily, and start using them on other trusses!
3) The modification is very simple to perform - no complicated cuts or fiddly assembly!

Here's one more shot from the front, showing that the roof piece completely covers the tops of the two trusses it is slotted into:

I made the roof 'cover' hang over the original roof by 2mm on each side, which brings it nicely to the edge of the truss. The extra bit you have to add on is 2 layers thick, which raises the top layer up above the truss.

So, I'm moving ahead this this design this week.

Quick update to show what this would look like with a 2-way truss supporting two roof pieces.

So, yeah, they overlap a little bit. But, that means they're covering up the truss nicely. Also, it's only one layer of cardstock that's overlapping, so it's not all that unpleasant. I just took these test roof pieces and stripped off the extra overhang.That left a 2mm gap between them. Yuck! I tried to shave just 1mm off of the overhanging bit, and yeah - if you've got laser precision, you might get them to fit snugly, but chances are you're going to have a little overlap or a little gap. I'm happy with the intentional overlap.
That's just an ugly close-up of the current overlap. That's about as bad as it gets.


  1. How does that work with longer roofs, where you need to align multiple roofs ?
    Don't your roofs step on one another, possibly leading to a superposition of roofs ?

    1. I updated the post with some pics and thoughts. I am hoping to build a bunch this coming week, which will let me build some structures and get a feel for how it really works.

  2. It's looking really good so far !
    Glad that 2-way trusses work great also!

  3. Great idea, so simple..... yet no converting trusses! Awesome
