A roof angle of 6 degrees = 1.26 / 12 rise or pitch.
If I remember right it should be between a 5 and 6 pitch. Between a 5/12 pitch and 6/12 pitch. If it was 27.5 degrees it would be a 6/12 pitch. Enter in "roof pitch" in the Google bar and several sites will come up where you can calculate pitch. The 12 means 12 inches. So that it would be aproximitely 6 inches rise to 12 inches of run. Hope this helps and I hope I remember my roof pitch angles. It has been a few years since I have done it.
If you do not have access to a roof framing book, I would use a tape and measure it. Length x width = square footage. My book says you should come up with : 11.33 x 12 = 135.96 sq ft
Place a four foot long level on the roof, parallel with the ground. With one end touching the roof and the other end in the air, read the bubble on the level. When the bubble says it is level, then have a second person measure the distance from the end hanging in the air straight down to the roof. Divide the number by 4. (example: with level bubble showing "level"; your helper reads 24 inches on the tape measure-- you divide 24 by 4 = 6" Your roof pitch is 6 /12, or 6 in 12." Every 12 inches of level travel your roof goes up 6 inches.
a 100 foot run with a 50 foot rise would give you a 6/12 pitch

This represents the pitch of the roof. Referred to as 6/12 pitch. This means that if you measured horizontally for 12 inched it will go up 6 inches.

A 4-12 pitch with a 30lb snow load will hold approximately 6 feet of wet snow. If you went to a 40lb-snow load and kept the roof pitch at 4-12 your roof would be able to hold 8 feet of wet snow. We don't get that much dry powder in New England...:)
6 feet, 8 inches.
In regards to roofs. "Pitch" is a ratio of the total rise of a roof over the total span of a building. "Slope" is a ratio of the total rise of a roof over "half" the total span of a building. A building 40 feet wide with a total roof rise of 10 feet (from the top of the supporting walls) has a pitch of 10/40 reduced to 1:4 A building of the same dimensions will have a slope of 1:2 or 6/12 on the imperial framing square.
If you have a scale drawing of the roof plan you can then look at a roof framing book find the page that has the pitch your rafters are at, look at the chart. Ex. - your span, (the distance from the outside of on wall to the outside of the other) is 20' and your pitch is 6/12, your rafter length is 11' 2 1/8" so you would buy a 12' 2 x 6. Do this for every board. (remember this is to the outside of the walls, if you want your tails attached you have to add your overhang to the length) If none of this makes sense or you have more than a simple gable or hip you are dealing with, I would seek a framer...
If you had a 4/12 pitch and the ridge was running the 20' direction and you were planning on a 12" overhang, your 2x6 rafters would be just shy of 9'-6" each. If your framing is 16" on center you will need 34 of them.
