What is a roof with 4 sloping sides?
A mansard roof is a four-sided gambrel roof, with each side having a double slope of one steep slope, and one shallow upper slope. Mansard roofs are a popular option for buildings wishing to maximise the amount of living space in the building, providing the option to use the loft as an additional living space.
What is a slope on a roof?
What is roof slope? – The slope of a roof, often referred to as the pitch, is determined by “rise over run” – the roof’s vertical rise in inches for every twelve inches of horizontal length (the run ). So a roof with four inches of rise every 12 inches horizontally (run) would have a slope of 4/12 (sometimes displayed as 4:12).
Flat Roof: 2/12 Low Slope: 2/12-4/12 Conventional Slope Roof: 4/12-9/12 Higher Slopes: 9/12 – 20/12 Steep Slope: 21/12 and higher
What is a roof with 2 slopes called?
Mansard Roof – A mansard roof, also called a French roof, is a type of a gambrel roof, which has two slopes on each side. The lower slope has dormer windows and is steeper than the upper one. The peculiarity of this roof style is that only its lower side is visible from the ground.
Why is it called four cardinal directions?
Beyond geography – Cardinal directions or cardinal points may sometimes be extended to include elevation ( altitude, depth): north, south, east, west, up and down, or mathematically the six directions of the x-, y-, and z-axes in three-dimensional space,
- Topographic maps include elevation, typically via contour lines,
- In astronomy, the cardinal points of an astronomical body as seen in the sky are four points defined by the directions toward which the celestial poles lie relative to the center of the disk of the object in the sky.
- A line (a great circle on the celestial sphere ) from the center of the disk to the North celestial pole will intersect the edge of the body (the ” limb “) at the North point.
The North point will then be the point on the limb that is closest to the North celestial pole. Similarly, a line from the center to the South celestial pole will define the South point by its intersection with the limb. The points at right angles to the North and South points are the East and West points.
- Going around the disk clockwise from the North point, one encounters in order the West point, the South point, and then the East point.
- This is opposite to the order on a terrestrial map because one is looking up instead of down.
- Similarly, when describing the location of one astronomical object relative to another, “north” means closer to the North celestial pole, “east” means at a higher right ascension, “south” means closer to the South celestial pole, and “west” means at a lower right ascension.
If one is looking at two stars that are below the North Star, for example, the one that is “east” will actually be further to the left.
What type of roof has 4 sides?
3. MANSARD ROOF – A mansard roof, also known as a French roof, is a four-sided roof with a double slope on each side that meet forming a low-pitched roof. The lower slope is much steeper than the upper. The sides can either be flat or curved, depending on the style. The Pros: Mansard roofs can help create a great deal of extra living space.
Using the space as a full attic or living quarters, called a garret, is very popular. The style lends itself to either open or closed dormers for more aesthetic appeal. This type of roofs are great for people wanting flexibility to make future home additions. When first designing and building a home, you can actually save money by having a simple mansard design to start off.
You can then add on a garret or dormers at a later date. This will not only add value to the house, but it also allows homeowners to easily make additions as their needs change. Cons: A low pitched portion of a mansard roof isn’t ideal for areas receiving heavy snowfall.
- Mansard roofs cost more than typical roofs because of the embellishments and details that go into them.
- But, the added space and character can more than make up for the extra cost of initial construction.
- Materials: Since a mansard roof has such a unique design, choosing a unique material could make the roof that much more special.
Using metal, such as copper or zinc for the steep portion of the roof, can be more expensive up front, but will require much less maintenance down the road, making it a good long-term choice. Using wood or slate shingles in a diamond pattern is a way to make a mansard roof stand out.
- However, overlapping composition shingles should not be used,
- Asphalt shingles can still be used on a steeper portion of the roof in a regular pattern.
- Types of Mansard Roofs Mansard roofs can take various silhouettes, including straight-angle, convex or concave.
- Windows are very important to provide light for the extra living space provided.
Grand houses may also display wood quoins, trim or decorative cut stone.
What is a Level 4 roof?
How Do Roofing Shingles Qualify for a Class 4 Rating? – Back in the mid-1990s, after a series of catastrophic hail storms across the U.S., the roofing industry developed a test to evaluate their products’ resistance to impact. This standardized test is known as the Underwriters Laboratory 2218 (UL 2218), and is also nicknamed “the steel ball test.” Based on the results of this test, UL assigns one of four ratings to a shingle, with Class 4 being the highest possible rating.
- During this testing method, a steel ball is dropped from a specified height onto an installed roofing shingle several times.
- The shingle is then turned over and inspected for any breaks or cracks that could potentially allow water to leak through.
- To receive a Class 4 rating, a roofing shingle must withstand having a 2-inch steel ball dropped multiple times from a height of 20 feet.
For more perspective, if this same test is repeated on a 4-inch concrete paver, the force of the steel ball would crack the paver in half. While Class 4 is the highest rating for impact resistance, there are also lower ratings a shingle can receive, such as Class 3 and Class 2.
What is a sloping roof top called?
Gable Roof – The gable roof is by far the most popular style for sloping roof types. An easy way to identify this type of roof is by remembering how houses look like in Monopoly game pieces. Two rectangular, usually equal sized panels join each other at an angle to form a ridge, and you get a gable roof.
- This style of sloping roof types is an industry typical for residences.
- Homeowners can find different materials to build this roof.
- Architects pay special attention when designing such roofs to avoid 45 degree angles.
- This is in accordance with industry norms and standards.
- By doing such, architects make outer walls shorter.
This results in more emphasis on the roof. It also gives a more pleasant looking overall balanced feel to the house.
What is a roof with sloping ends and sides?
Gable Roof Shapes – Gabled roofs are the kind young children typically draw. They have two sloping sides that come together at a ridge, creating end walls with a triangular extension, called a gable, at the top.
What is the sloped edge of a roof called?
6. Parts of the Roof’s Edge – The basic layers of a roof that we’ve covered so far aren’t enough to protect your home. Water can’t just roll off your shingles and down the face of your house, or your bricks or siding would be damaged. Plus, the water would collect around the base of your home, which could cause foundation issues.
- So, at the roof’s edge, a series of roof drainage components are installed to protect your home from these potential problems.
- First, you have to understand that there are two types of edges on a roof: eaves and rakes.
- An eave is a horizontal edge where the roof hangs over the exterior wall.
- A rake is a sloped edge where a roof hangs over the exterior wall.
It is essential to handle the drainage from a roof at the eave properly and protect against wind-driven rain at the rake. Here are the parts of a roof edge:
Drip Edge: When water reaches the eave edge of a roof, it meets the drip edge, also called the eaves flashing. This is a thin metal strip that directs the water into the gutters. In most cases, the roofing professional should install the drip edge before the underlayment on the eaves and after the underlayment on rake edges. Without a drip edge, water may not properly drain and could flow down the wall surface and “wick” or absorb into the exposed edge of the wooden decking. This can rot out the edge of your roof, potentially leading to more problems.
Fascia: A fascia is the topmost vertical component of the exterior where it meets the roof edge. The roofing professional places the drip edge at the edge of the roof deck, and the rain gutter is attached to the fascia.
Gutters and Downspouts: Gutters are the plastic or metal troughs that take the water away from the edge of the roof. They connect to downspouts, which bring the water down and direct it to drain away from the home’s foundation. Without the downspouts to direct the water away from your home, you could develop foundation issues or other damage.
Soffit: Many roof styles include a soffit. When the eave edge of a roof extends past the exterior wall, the soffit is the horizontal underside of this extension. Often, soffits are perforated or have built-in vent openings to provide ventilation for the attic space. Soffit vents, coupled with ridge vents at the top of the roof, can be a very effective way to achieve proper roof ventilation.
All of these roof components work together as a system to drain water away from your home and protect it from the elements.
What is a catslide roof?
Roof Ends – Gable The term Gable end usually also includes the triangle of wall beneath the roof covering. Roof Ends – Full Hip A hip is where the end of the roof is sloped from the eaves level up to the ridge. Roof Ends – Barn Hip A barn hip can also be called a half hip, clipped gable or Dutch hip. This is where the top portion of the gable is replaced with a small hip. Roof Ends – Gablet A gablet, also called a Dutch gable, is where you have a hip end with a small gable at the top. Catslides A catslide roof is a roof that continues down below the main eaves height and allows you to have a greater depth of building without increasing your ridge height. Dovecotes Dovecotes come in two types, functional and non-functional. The only difference between the two is that the function one has internal partitions so that a dove will nest in one of the compartments. Doves will not nest in a non-functional as the wind will just blow right through. Clock Tower Our clock towers are much the same as the Dovecotes except all four sides are boarded and we supply one clock face to be fixed to one of the sides. The clock faces come in a choice of six colours Black, British Racing Green, Navy Blue, Light French Blue, Burgandy and White.
What does a 4 slope mean?
Nomenclature – Illustration of grades (percentages), angles in degrees and ratio. There are several ways to express slope:
- as an angle of inclination to the horizontal. (This is the angle α opposite the “rise” side of a triangle with a right angle between vertical rise and horizontal run.)
- as a percentage, the formula for which is which is equivalent to the tangent of the angle of inclination times 100. In Europe and the U.S. percentage “grade” is the most commonly used figure for describing slopes.
- as a per mille figure (‰), the formula for which is which could also be expressed as the tangent of the angle of inclination times 1000. This is commonly used in Europe to denote the incline of a railway. It is sometimes written as mm/m instead of the ‰ symbol.
- as a ratio of one part rise to so many parts run. For example, a slope that has a rise of 5 feet for every 1000 feet of run would have a slope ratio of 1 in 200. (The word “in” is normally used rather than the mathematical ratio notation of “1:200”.) This is generally the method used to describe railway grades in Australia and the UK. It is used for roads in Hong Kong, and was used for roads in the UK until the 1970s.
- as a ratio of many parts run to one part rise, which is the inverse of the previous expression (depending on the country and the industry standards). For example, “slopes are expressed as ratios such as 4:1. This means that for every 4 units (feet or metres) of horizontal distance there is a 1 unit (foot or metre) vertical change either up or down.”
Any of these may be used. Grade is usually expressed as a percentage, but this is easily converted to the angle α by taking the inverse tangent of the standard mathematical slope, which is rise / run or the grade / 100. If one looks at red numbers on the chart specifying grade, one can see the quirkiness of using the grade to specify slope; the numbers go from 0 for flat, to 100% at 45 degrees, to infinity as it approaches vertical.
- Slope may still be expressed when the horizontal run is not known: the rise can be divided by the hypotenuse (the slope length).
- This is not the usual way to specify slope; this nonstandard expression follows the sine function rather than the tangent function, so it calls a 45 degree slope a 71 percent grade instead of a 100 percent.
But in practice the usual way to calculate slope is to measure the distance along the slope and the vertical rise, and calculate the horizontal run from that, in order to calculate the grade (100% × rise/run) or standard slope (rise/run). When the angle of inclination is small, using the slope length rather than the horizontal displacement (i.e., using the sine of the angle rather than the tangent) makes only an insignificant difference and can then be used as an approximation., Or more simply, one can calculate the horizontal run by using the Pythagorean theorem, after which it is trivial to calculate the (standard math) slope or the grade (percentage). In Europe, road gradients are signed as a percentage.

What is another name for cardinal directions?
Cardinal Directions – A cardinal direction can also be referred to by first using the word “due”. For example, the cardinal direction of north can also be referred to as due north. On a compass rose, which is a symbol found on maps that shows directions, there will be four points indicating north, south, east, and west.
