What is roof pitch and why does it matter?
That is to say, the roof pitch (expressed as a ratio) tells you how many inches the roof rises for every 12 inches of depth. So, let’s say a roof rises 6 inches for every 12 inches in depth towards the peak. The roof pitch would be described as a 6:12 pitch. The primary reason roof pitch exists in the first place is to redirect water.
What type of roof pitch is best for your home?
There are two main types of roof pitch to choose from when deciding what roof will be best for your home: low pitch and high pitch roofs. Below, we detail common pros and cons of each roof pitch variation.
Are high pitch roofs more expensive to maintain?
Due to a steeper grade of roof pitch, high pitch roofs are not as easy and safe to access when maintenance/inspection is required. This can make maintenance costs a bit higher for high pitched roofs. A tradeoff for fewer maintenance calls, compared to their low pitch counterparts.
What are the benefits of a low pitch roof?
The lower pitch of the roof means greater walkability. Low pitch roofs are safer and easier to access when maintenance and/or repairs are needed. Especially for homes in the south, a low pitch roof means a cooler interior.
Why is a pitched roof better than a flat roof?
Pitched roofs are strong and resilient. Pitched roofs are more stable than flat roofs during periods of heavy rain and offer far more effective drainage. The water drains off a pitched roof easily and uniformly, whereas on a flat roof water can build up, creating structural pressure.
Why are roofs high pitched?
There is less danger of pooling water: Upon high-slope rooftops, gravity will make short work of any dampness—as your roof rapidly channels the water down inside gutters. The lower a slope, the longer moisture remains on a rooftop in which it degrades materials then turns weak spots to leaks.
What is the purpose of a pitched roof?
Protection against enviromental hazards. Pitched roofs are built to withstand snow, ice, water and wind. Shaped as a triangle, they are stable, stronger and ensure perfect water drainage. Some roofing tiles, like natural slate, are extremely tough, waterproof and fire-resistant.
Why don t houses have flat roofs?
Their pitch, or slope, can be steep or gradual depending on the home's design and layout. It's easier for water to drain on a pitched roof compared to a structure that's more flat. However, they're also generally harder to maintain given their steep slopes.
Is a higher pitch roof better?
There's less danger of pooling water: On high-slope rooftops, gravity makes short work of any moisture—as the roof quickly channels the water down into gutters. The lower the slope, the longer moisture lingers on the rooftop where it degrades materials and turns weak spots into leaks.
Which roof pitch is best?
Pros. Since a low pitch roof doesn't require as many shingles, more often than not, a low pitch roof will end up being more cost-efficient during installation. The lower pitch of the roof means greater walkability. Low pitch roofs are safer and easier to access when maintenance and/or repairs are needed.
Does a flat roof need a pitch?
What Pitch is a Flat Roof? If flat roofs are to work well, they have to have a slope, known as a fall, to shed rainwater. The fall should never be less than 1:80 and preferably about 1:40.
What is a pitched roof called?
1. GABLE ROOF. Also known as pitched or peaked roof, gable roofs are some of the most popular roofs in the US. They are easily recognized by their triangular shape. The Pros: Gable roofs will easily shed water and snow, provide more space for the attic or vaulted ceilings and allow more ventilation.
Why do they put rocks on a flat roof?
Rocks or gravel on a flat roof are a necessary component for built up roofs and ballast roof systems. The gravel or stone offers roof protection and balances the overall weight of the roof. Built up flat roofs are constructed with layers of roofing felt and asphalt, where the top layer is embedded with gravel.
Why are factory roofs slanted?
A saw-tooth roof is a roof comprising a series of ridges with dual pitches either side. The steeper surfaces are glazed and face away from the equator to shield workers and machinery from direct sunlight. This kind of roof admits natural light into a deep plan building or factory.
Why do architects like flat roofs?
Modern houses often have flat roofs because of their low cost, ease of maintenance, and potential for additional space. Flat roofs were also a pinnacle of Mid-Modern architecture. As this particular design style regains popularity, some of its elements, such as the flat roof, are coming back.
Is higher roof pitch more expensive?
As far as materials are concerned, a higher roof slope will not only cost more in shingles but also nails, roofing cement, and other materials. This, in turn, will increase the cost of labor as more nails and more cement will require more time to finish installing.
What is the disadvantages of a steep pitched roof?
Steep-Slope: Cons This is a challenge or even impossible on a significantly sloped roof. Mounting heavy equipment or large objects on a steep-slope roof can create run-off blockage. The most common problem arising from steep-slope roofs is clogged gutters that result from the run-off debris.
What happens if roof pitch is too low?
With a low pitch roof, you may find debris and dirt build, which can look unsightly and potentially damage the roof and building structure over time if not removed. You should maintain the roof like other parts of your home by checking it regularly for debris build up or cracks in tiles.
What is the most common roof pitch?

Why does my roof pitch vary?
Roof pitches vary for one big reason: water redirection. Whether rain or snow, water accumulating on your roof is a very, very bad thing.
What is a pitched roof?
A pitched roof is exactly what it sounds like – a roof with some kind of slope or angle that creates a peak, or peaks. If a roof isn’t completely flat (and very few actually are,) then it is considered a pitched roof.
What is Roof Pitch?
Pitch describes a roof’s angle. You might’ve seen other terms used to describe a roof’s pitch, such as “slope,” “slant,” or “gradient.” Ultimately, all of these terms can be used interchangeably, but “pitch” is the common term used.
What is the pitch of a low slope roof?
Low-slope – These roofs typically have a pitch between a 1 and 2, or 1:12 and 2:12. Sometimes confused with flat roofs, these low-sloped roofs do have a bit of angle to them to allow water to run off.
What is a steep slope?
Steep-Slope – Any pitch above a 9.

Is a flat roof safe?
The same goes for climates not prone to massive snowfall. If you live in an area that doesn’t get a lot of snow, then a flatter roof is just as safe as a high-pitched roof. If it snows a lot where you live, you’re going to want a steeper pitch on your roof so snow has less of a chance to accumulate en masse. Otherwise, the weight of that snow could cause you roof to sag or even collapse!
Why is it important to have a pitched roof?
It is an essential element to ensure water drains properly off of your roof. The pitch of your roof also helps determine the type of materials that can be used on your roofing system.

From a professional standpoint, a steep roof is also a lot easier to check for any warning signs (without having to pull out the ladder). 4. Storage space: All that space under a steep roof pitch is good for more than just air! A steep roof encourages the development of larger attic spaces that are great for seasonal or long-term storage.
Why is a pitched roof better than a flat roof?
This is because the slope of the roof helps the precipitation slide off rather than pooling up.
What is the pitch of a roof?
A roof's pitch is the dividend of the roof's vertical rise divided by the horizontal span and defines the roofline's steepness. This pitch is written as a ratio where the first number is the inches that the roof rises while the second number classifies the horizontal area (usually 12").

The Reason Roofs Are pitched?
The Need For Maintenance on Pitched Roofs
- Unless your home is rectangular, you’ll have multiple pitches meeting. The point they meet is the valley.
The More Valleys, The Greater The Risk.
- More valleys mean more opportunity for debris to build up. The pitch itself matters less. With shallower pitches, debris can build up quicker in the valleys due to slower water flow but with steeper angles, valleys are more protected from the wind. Where steeper pitches have a greater impact, is with gutters. The steeper angle means faster water flow off the roof surface. While thi…
