DEAR TIM: I’m now retired and starting to advance a huge account of projects. One of them is architecture a simple shed, and I accept no clue how to cut and actualize a simple roof rafter. I apperceive it can’t be that hard, but I’m confused. What’s the process, and do you anticipate a amateur with little or no acquaintance can cut simple rafters to actualize a basal gable roof? – Paul E., Canton, Michigan
DEAR PAUL: Roof framing is one of the aspects of architecture I savored as a architect and carpenter.
I’ve got acceptable news: Not alone can you cut a simple accepted roof rafter, but you can also, with basal guidance, cut hip and basin rafters forth with all the jack rafters that affix to them.
You will charge a framing square, a band measure, a pencil and a saw. That’s it. It will additionally advice you if you anamnesis some of the basal geometry you hopefully abstruse in aerial school.
A roof axle is aloof the hypotenuse of a appropriate triangle. Accomplish a simple band cartoon of a gable and you’ll see that it is aloof two appropriate triangles continuing aback to back, apery one another.
If you attending at a accepted carpenter’s framing square, you’ll bound see you accept two of the legs of the triangle in that tool. They anatomy the 90-degree angle. The third side, or hypotenuse, of that triangle can be created by aloof abutting one of the numbers on anniversary leg of the framing square. That’s the abracadabra of creating a roof axle in its best basal form.
The bend of accepted roof rafters is appointed by anecdotic the acceleration of the roof per basal of run. You may apprehend a carpenter say, “Your abode has a 4/12 roof.” What he’s adage is the roof on your abode rises 4 inches for every 12 inches of accumbent run. (In the United States, the run amount in the denominator is consistently accustomed as 12.)
If you lay a framing aboveboard on a table and attending at the numbers on the alfresco edge, you’ll see they alpha counting out from the corner. What your carpenter would do is go up the attenuated leg of the framing aboveboard to 4 inches and go out on the fatter leg 12 inches. If you lay a straightedge amid these two credibility on the framing square, you’ll actualize the angled allotment of the triangle.
The aboriginal affair you charge to do is actuate your roof slope. How abounding inches of acceleration will your roof accept per 12 inches of run? You ability appetite to bout the abruptness of your abode roof, or you can go with a 4/12 roof slope, as that will afford baptize but it’s not so abrupt as to be adamantine to assignment on.
Then actuate the amplitude of the shed. You charge this altitude because bisected of it will be the abject of your big triangle. Let’s say you’re activity to accept a afford that’s 10 anxiety wide, and you’ve absitively to go with a abruptness of 4/12. This agency your simple band cartoon of your roof will appearance the aiguille of the triangle to be 20 inches aloft the top of the walls. That’s because for anniversary basal of accumbent run from the alfresco of the afford wall, the roof climbs 4 inches, and bristles times four equals 20.
In reality, the aiguille of your roof will be apparently 23 inches aloft the absolute top of the walls. This happens because you will accomplish a little birdsmouth cut in the abject of the axle so it sits collapsed on the top bowl of the wall. Best rafters extend bottomward accomplished the bend of the exoteric wall, creating an overhang. Roof overhangs are acceptable things because they accumulate rainwater abroad from the abandon of the building.
You will accept a heel aloft the cleft in the rafter, and the heights of these heels alter with the admeasurement of the roof rafter, the amplitude of the wall, and the admeasurement of the birdsmouth cut. This is the allotment of the job that will abash you.
Here’s how you use your framing aboveboard to admeasurement and cut the barge for a rafter: Starting at one end of the allotment of lumber, lay the aboveboard on the collapsed lath and use the alfresco edges of the aboveboard and adjust the roof abruptness numbers you’ve absitively to use. You’ll apprehension the attenuated leg of the framing aboveboard makes an angled band beyond the lumber. Draw that band with a pencil. That will become your erect cut up at the top of the axle area it touches the opposing axle or a centermost backbone board.
Before you move the framing square, accomplish a pencil band beyond the barge forth the basal bend of the fatter leg of the framing square. Slide the framing aboveboard bottomward the barge and adjust the attenuated leg on this mark and echo the appearance action so you actualize a avalanche of baby triangles that represent your roof slope. If your afford will be 10 anxiety wide, you’ll end up with bristles of these triangles and sets of marks as you advance bottomward the allotment of lumber.
Making the birdsmouth cut area the axle sits on top of your afford bank is not too hard. The framing aboveboard legs actualize both curve for you. Use the aboveboard to accomplish one aftermost final band that’s alongside with the aboriginal band you drew at the far end of the rafter. This band extends bottomward from the tip of the aftermost baby triangle you created. Adjust the framing aboveboard one aftermost time with your roof abruptness numbers and be abiding the added allotment of the aboveboard avalanche beyond this aftermost line. It will anatomy a 90-degree bend to the aftermost vertical line. Trace forth the aboveboard a band that extends from the aftermost vertical band about two inches.
This tiny little triangle of wood, already cut out of the rafter, makes a bound bend acceptance the axle to sit collapsed on top of the bank and the added ancillary of the cleft applicable bound adjoin the vertical face of the alfresco of the afford wall.
You may accept to accomplish a brace of analysis cuts to get this right. Acceptable luck!
