This means for every 12 inches of horizontal run, a roof rises 3 inches. The first thing you need to know is if your roof has a slope that is less than or greater than 3:12. But what is the difference? Simply put, it comes down to what is needed for your shed. If you use 2×6 lumber for rafters, your ridge beam will be 2×8.Īlso Check: Where Do The Screws Go On A Metal Roof Vs 26 Rafters: What Is The Differenceĭepending on the pitch of your shed roof, you will choose between 2×4 or 2×6 rafters. Remember that for rafters, youll always use a ridge beam one size larger. Well be using a ridge beam for this project, so each set of rafters will meet a horizontal 2×6 at the apex, which will run the length of the shed and connect to all of the rafters. The process will generally be the same for a shed of any moderate size, but be sure to use the rafter sizing calculator above to find the correct rafter length and size for your shed rafter project.

Now that youve got a decent idea of how big your rafters are going to be, well go through how to build them step by step.Īs an example, well use a 10×8 foot shed, with the span being 8 feet. Lets get down to business and build some rafters.

#Roof rafter plus#
We actually considered leaving this area open and adding glass here to allow more light into the bedrooms but decided against it due to the cost of the glass, plus I would have had to run it by the HOA, and they probably would have denied because it doesnt match our main house. We repeated the process at the other gable end and then we could move inside the house to finish the framing in the gable area. Once both boards fit well, we ran more screws to attach the board to the sheathing more securely, as well as to the eave fascia, and we tweaked the boards as needed to get them in line with the edge of the sheathing, which we knew was straight. We repeated the process with the other board, and Erik actually fine tuned this board with his circular saw before attaching it to the sheathing. I cut the board a hair long on the first try but, after taking a hair off, Erik got the board temporarily attached to the roof sheathing. Next, I got one of the fascia boards cut to length, making parallel angled cuts at each end, and the angle here once again matched the roof pitch. Adding Fascia To Gable EndsĪnyway, moving on, we could get the fascia added at the gable ends, and first we snapped a chalk line and cleaned up the edge of the roof sheathing here, to make sure the fascia ran nice and straight. If you want to build a roof truss with the use of other materials aside from wood, like steel, aluminum or tin, you will need to cut the material based also on the roof size and design specifications, just like with wood trusses. Depending on the woods thickness, you might also want to use thicker screws. The plates and the wood will join together in the shape of a triangle and will then be fastened together using galvanized steel screws, which arent shorter than 1 ½ inches in their length.
