The roof angle is one of the most complicated parts of construction of a home. For some people they simply leave it up to the contractor's and don't spend any time trying to figure it out. However, know how to go ahead and figure out a home's roof angle, or roof pitch as it is commonly referred to as, is an essential home improvement skill that must be learned.
Many home improvement projects require a roof. A front porch addition, car port, portico, gazebo, shed, barn, or any other building that needs a roof. Making the correct calculation on the roof's pitch can save the roof and save you from having to make costly repairs.
Roof Angle Considerations
The angle of the roof pitch that you have for your building can dictate many different things.
Material Used - If you are using a steep pitch for your roof construction then materials like asphalt shingles, or slate shingles are best suited for this type of pitch as they can be tightly overlapped to increase water shed. A metal roofing materials is ideal for a lower pitch as snow, and rain can easily slide off it its slick surface.
Weather - The climate that you live in will have a large say in how much pitch your roof should have. For example, for homes in the Northeast, you will need a steeper roof angle than homes in the Southwest. Snow build up can lead to major damage of the home due to melting, ice build up, or sheer weight causing a cave in.
Size of Home - The overall size of the home is also another consideration. If you are going to have multiple peaks and angles, then you will have to devise several roof pitches, and the angles are not all that important, but for a traditional gable roof a steep pitch will mean a much larger roof, more materials, and more cost.
Determining Roof Angle
Determining the roof angle for your home's construction or home improvement project is a straightforward process.
1. Get a ladder and set it to a place where you can unobstructed access to the roof level.
2. Bring a level and tape measure with you for determining angle.
3. Mark off 1-foot intervals on the level.
4. Place the end of the level on the roof and hold the level horizontal so that the leveling indicator is in the middle. At the 1 ft. mark on the level measure to the roof surface keeping the tape measure perpendicular to the level.
5. If the distance if 6 inches then the roof angle is said to be 6 inches of rise over 12 inches of run or a 6:12 pitch.
The roof angle is an important part of building, or determining if the roof pitch is going to be enough for the climate conditions. Whether you are going to use slate, asphalt, or metal roofing, know the pitch of the home will be a big factor as to which you choose. Use this easy way to calculate roof pitch for future buildings of your own.
