First timer building stick building with trusses

Hi, I just joined, and love the information here. I am building a stick building in Costa Rica, approx 10ft ( maybe 12ft) by 16-18 ft. The roof will be tin, and I was told it would be easier to get 8ft lengths to avoid cutting. I am building my trusses using 2by4's, as the roof does not need to be that strong ( tin roof )... Questions: 1) to keep it simple, can i go without the ridge board? 2) will 2x4's be sufficient to construct the trusses which will support the roof with a span of 10 to 12 ft? 3) if i use 8ft tin ( slope with a 1ft overhang), with a run of 5ft ( or 6ft), what will my rise be? Geometry tells me that i can use the formula, a2 + b2 = c2, where c2 is the slope. What else to I need to consider?

Thanks guys!

Roof

Trusses are used without a ridge board. 2x4's are sufficient for your building. The strength of the truss varies with its design. I need to do some calculations and post back on the slope for your plans. If I read correctly, you want to span either 10 or 12 feet with the trusses and have a 1 foot overhang. I will post back.

Truss

Welcome to the forum!

Here is rough diagram of a truss with 12 ft span and 6/12 pitch.

Hope this helps. Good luck with your project.

He can correct me if I'm wrong, but I'm just guessing that the OP is thinking of "rafters" when he uses the word "trusses". Otherwise he would not be asking about the need for a ridge board.

If so, he isn't planning on actually building trusses like wirepuller drew and would be wise to use a ridge board. Eliminating the ridge board does not simplify the framing, it compromises it.

Rafters

I should have read more closely. XSleeper is right. "Stick build" should have tipped me off. By all means use a ridge board when building with rafters. The 6/12 pitch should still work for an 8 ft. rafter with 1 ft. over hang and 12 ft. span. Good luck with your project.

Will this building be in a hurricane-prone location?
