    It's been too long since I've use any real math. I need some help in finding the surface area of my roof.

    It's 24 ft wide by 48 ft long with a 42 degree roof. My uncle just stopped by and said he'd do it if he had help, but he can't, and I need to replace 4 of the 6 trusses holding the roof up, then add at least 5 more because the 8 ft spans are too far apart to properly support any snow weight. Which is why the roof is caving in.

    Anyway, I'm not good at this.

    I dunno. These are rough estimates on my garage. It was a shitty build on a crappy pullbarn design. Each truss has 8 feet between it.

    Never mind, I see it's a 42 degree roof now.

    That's a big garage.

    Are they trusses or rafters? Seems crazy to build something with an 8 ft span between supports. There essentially would be no support for each sheet of roof decking.

    Yeah it was built by a mechanic, three car garage.There's a 6 ft deep oil pit on one side even.

    There are triangular trusses at 8 foot intervals and then he used 2x4s perpendicular to them to hold the plywood/shingles. The first hole started dead center between two trusses.

    That's your problem right there... Not to code to begin with, he probably bought a single truck load of A-Frame supports and had to figure out how to make it work, lol.

    Yup. That's the first thing dad and my uncle both said upon walking inside.

    That far north, I'm surprised it didn't fail the first snow.

    Brian left in 2010, it started falling in on itself in a few places before that time.
