So what if you want to build a canopy over your door. What would you usually do? Well, we would typically call for a carpenter. However, we have the option of building it ourselves if we know the procedure correctly.
So this article is for those who want to be a little adventurous and handy and make their door canopy by themselves. Also, keep in mind that you are also saving a lot of your money.
Well, it may be tricky for starters, but with some simple steps, you can also do it yourself. So let us discuss together how to build a door canopy for yourself.
Things that we need to know,
- Knowing porch and gable roof
- Using run and rise to find an angle for the roof you have in your house.
- Making roofing square
- Getting the length of rafters
1. Knowing porch and gable roof:
The gable roof is basically triangle shaped. It starts with a ridge in the center, and two sides are sloped down on opposite sides from the ridge or center. The sloping is calculated carefully to shed snow and rainwater successfully.
- Ceiling joint
- Wall plate
2. How to Use run and rise:
To know about using run and rising is knowing about the proper angle you should use to place your canopy roof. To figure it out accurately, we need to see the distance between run (travel) and the height, also known as the rise.
After getting the numbers for the run (travel) and height (rise), calculate them. To measure run, we need to use foot per run. One foot is 12 inches. For an inch of a roof rise, there is an equivalent angle.
For instance, when a roof rises 10 inches, traveling 1 foot, the roof angle increases to 40 degrees.
The calculations based on your roof:
Run has to be measured from a distance out from the wall along the ceiling beam. The run is always lesser in thickness compared to the ridge thickness.
To measure the length of the rise, we need a measurement of height from top of the ceiling beam to the top of the ridge.
Formula to get the angle is here is, rise (inches) divided by the run (feet).
So, imagine the run is 26 inches. We have to minus the 2inches ridge. So it is now 24 inches.
And the rise is 20 inches (imagine). Dividing it by 2 gives us 10 inches. This is equal to the 40 degrees for the pitched roof.
3. Making a Roofing Square
To make the roofing square, we have to take a plyboard and cut the corner. Make it 24 inches on one side and 16 inches on other. Starting from both corners, mark out 1 inch with intervals.
4. Obtaining the length of rafters
We may use the Pythagorean theorem (run square+ rise square= c square).
Porch in our example is =24^2 = 576
Rise = 20^2=400
Equal= 576+400= 976
The square root of 976 is = 31.24
Rafter is, therefore 311/4 inches.
It may seem all tricky with all the equations. But if you follow the steps and do the calculations carefully, you will be good to build your canopy for your door. It is also recommended that you take help from experts if you can.
FAQ Of How To Build A Door Canopy Yourself
- What is a canopy for a door?
Ans: It is the small roofing system usually found over the door. This is built to give protection from snow and rainwater.
- Are the numbers standard for all roof?
Ans: No, it depends on the shape and structure of your roof. Again, with the same structure, you have to make sure you take the measurement for your building’s roof.
- What if I use different units?
Ans: You can use a different unit. But make sure you convert them properly to get the accurate value.
- Is there any chance to get the wrong size if I am mistake with the calculation?
Ans: Yes. If you do not take the measurement exactly, then you may end up with a major error.
- Why is the Pythogorean theory necessary?
Ans: To get the roots and give you a proper direction.
