There are different types of roofs found around the world depending on where you live. Sloped roofs are perfect for rainy and snowy regions while flat roofs are well known across arid climate regions and commercial buildings.
Sloped roofs are complicated to make as it requires accuracy when it comes to measurements. The roof pitch or the slope or angle of the roof determines the installation method of the roof ensuring a clean construction. It also lets builders know how much roofing material will be needed to complete the roof.
Structural engineers and construction workers have taken pride in creating amazing roofs because they have the knowledge and know-how on how to make sloped roofs. However, if you’re on a DIY mission and motivated to complete your sloped roof then an online roof pitch calculator will help you a lot.
A roof pitch calculator not only tells you the angles, rafters length, and other important measurements but it also ensures optimal that with these measurements in place your roof is as sturdy as it can get. Without a roof pitch calculator, your DIY project might lead to an unpleasant experience with cracks in the roof which can be highly dangerous and collapse with time.
So, what is a roof pitch exactly? It’s the slope or as the engineers say, the vertical rise against the horizontal run of the roof is known as a roof pitch. For example, a 6-inch rise for every 12-inch run has a 6 inch per foot pitch. Roof pitches are often written as a semicolon or a fraction form. In the previous example, the roof pitch is either 6:12 or written as 6/12.
There are three important things to remember when it comes to roof pitches. The rise, run, and angle of the roof. Our roof pitch calculator will help you determine your roof pitch by simply plugging in the available values.
Here is how you can go about calculating your roof pitch.
1. Taking the measurements from the roof
Get ready to start your DIY by taking measurements. Get hold of a trusty tape measure and a long ladder. You will also require a foot long level. Head to the roof and get out your level. Hold the level, perfectly straight. This will allow you to measure the height of the roof. Start measuring the height from the roof exactly 12 inches away from where the other end of the level is touching the surface. This is the measure of the rise of the roof.
For example, if this calculated value on the measuring tape is 4 inches, then the pitch is 4:12 or 4/12.
2. Taking the measurements from the attic
You can also measure the slope of the roof from your attic. When in the attic, hold the level perfectly leveled like before but this time it should be touching the rafter at one end. Then measure the distance between the rafter and the other end of the level with the same distance of 12 inches.
The calculator below is an easy way to calculate your roof pitch. Simply plug in your values or adjust the slider accordingly to calculate the roof pitch.
