What is Roof Pitch?
The pitch of your roof is a factor that will determine the type of materials you can use. The roof pitch also determines the steepness of the slope, which can have an impact on water and snow runoff.
The pitch of a roof is typically shown as two numbers separated by a colon or slash, such as 2/12 or 7.12. You can measure it using a level, or with an app that uses the internal gyroscope of your smartphone.
The pitch of a roof is its inclination
Roof pitch is an angle or inclination of the roof with respect to the horizontal. The roof pitch is calculated by multiplying the height of the roof with its span. It is often expressed as a fraction such as 1/12, 1/2:12 or other. The flat roofs do not actually lie flat. They have a slight slope to them that helps water drain off.
The pitch of a roof can influence how snow, ice and rain will drain off the roof. It can also affect the roofing materials that work best for certain types of roofs. It is essential to know your roof's slope when planning additions, installing new skylights or cutting rafter boards. This information is useful for ordering the correct amount of material and calculating waste. It is easy to find the pitch of your roofing system from your attic using a level with a length of 18 or 24 inches, a tape measurement, and a pen. You can also use the calculator found on this page to determine your roof's slope.
Pitch is defined as a ratio
Roof pitch is also called slope. It is the ratio between a roof’s vertical rise and its horizontal run. This ratio is expressed as a fraction, with the first number representing the height of the roof and the second representing its horizontal run. A roof with a span and rise of 12 feet, for example, has a pitch of 4/12.
Roof pitch is usually displayed as a division slash (like 2/12 or 7/12) between two numbers. However, a colon may be substituted for the slash. The roof pitch affects the way water and snow flow off of a building or home. The roof pitch also impacts the type of roofing material that can be used. Calculators are faster than eyeballing the roof pitch. Mobile apps and tools can make the process easier, reducing the math involved.
Pitch is fraction
The pitch of a roof, also called slope or incline is the ratio between its height and its span. Professionals often refer to it as X overY. A roof with a pitch of 6/12 means that the height is 6 inches per 12 feet.
It is important to know the importance of roof pitch in the design and construction of a structure. This determines if a roofing material is suitable and helps estimate the amount of material needed.
Roof materials are usually rated for roof pitches between 12/12 and 15/12. You should never use a material that is too steep or too low. Asphalt composite shingles, for example, are suitable for roofs that have a pitch of up to 12/12. Wood and slate shingles, however, are not. These shingles are more likely to leak and don't lock as tightly together as other types of shingle.
Pitch is a percent
Roofs come in a range of slopes from flat to steep. The pitch is what matters most. Some roofs are designed to slope in both directions. The pitch determines what type of roof material to use and how it is installed. This also impacts the lifespan of your roof as well as how quickly it drains.
Roof pitch is expressed as the number of inches the roof rises (or the feet it extends) for every 12 inches horizontally. The pitch can be expressed in a number, such as 6/12, or a fraction (x:12).
The average residential home has a pitch of between 4/12 and 9.12 inches. Asphalt shingles are recommended for roofs in this range. Other types of roofing shingles will not work for low-pitched rooftops. Consult your architect if you're building a new home or replacing an existing roof.
