Pitched Roof
What Is a Pitched Roof?
Pitched Roof is a pitched roof is a type of roof that slopes down generally as two halves with an angle to the central ridge however, sometimes it is in one area that extends from one edge to one edge.
A roof is classed as a pitched roof if its pitch is more than 10 degrees. However, it must not exceed 70deg otherwise it is counted as an exterior wall.
Roofs are the highest component of a structure built as the frame to ensure that the structure is shielded from heat, rain and snow, wind, and other elements of the climate. It also assists in maintaining the interior living space of the house by preventing the loss of heat. Also Read: Gable roof
Types of Pitched Roof
The slope, the environmental conditions aesthetics, environmental conditions, and the number of sloping surfaces, pitched roofs can be broadly classified into the following kinds
1. Mono-Pitch Roof:
It is the simplest type of Pitched roof that is, the number of the sloping surfaces is one. I.e. It's a single roof surface that is sloping typically not connected to a roofing surface.
This kind of roof generally has the look of an equilateral triangle that is joined to the central ridge and at the other side, has extended over. It may be identified by different names, such as shed roofs, lean-to roofing, pent-roof and skilled roof.
The slope of a mono-pitch roof is determined by the ratio between its rise (considered as starting from the lowest point on the roof's ridge) and spread (considered as the distance horizontally that the roof is covered).
Mono-pitch roofs are typically constructed with a set of struts, principal ties as well as principal rafters, and angle purlins that allow the placement of roof sheets or roofing coverings. Also Read: Skillion roof house
Advantages of Mono-Pitch Roof:
As the most basic form of pitched roofs, it needs only a few components to build this roof and that is the reason these types of roofs are employed for storage rooms, garages, and go-downs.
To build this kind of roof there aren't many designs is required and this kind of roof are swiftly constructed and doesn't cost a lot..
With a slope of greater than 45deg and a slope of more than 45deg, it offers adequate drainage of rainwater and snowfalls which makes it an ideal option for areas with heavy rainfall. Also Read: What is stucco
2. Double-Pitch Roof:
It can be the most commonly used pitched roof in which the total number of the sloped surfaces is two which means that there are two surfaces that slope in opposite directions. opposing direction. Also, it is the result of the two roofs with mono-pitch.
The rise of a double pitch roof is similar to the same as that of a single pitch roof as well as its span horizontally is double that of the mono-pitch roofing.
The construction of a double pitch roof has a similar structure to the structure of the four-sided triangle. The material used in this type of roof is one set of principal tie-ups, two sets of primary rafters as well as struts and angle purlins, and struts that are used to put the roof covers.

Advantages of Double-Pitch Roof
This kind of roof is commonly used for homes for residential use. It offers the homeowner an extremely economical alternative for roofing and is visually attractive.
A slope that is in the range between 45 deg and 60deg that provides efficient drainage for houses that are in the middle of snowfall and rainfall areas.
The design of this kind of roof system doesn't require any effort and can be completed in a quick period of time. Also Read: Secant walls
3. Couple Roof:
As the most basic type of roofing, it's identical to roofs like the Gable roof, also known as a Double pitch roof. The sole difference is that the couple roofs can be built at a minimal cost and be constructed very quickly.
It is the materials employed to construct the structure of the two close roofs are mostly wood.
In the beginning, the plate wall is fixated on the walls supporting them (which majority of the time is a Masonry Pillar) in addition to the ridge piece is fixed on the center of the ridge. The primary rafters are fixed to the ridge piece as well as the other onto the wall plates. Also Read: Concrete stem wall
Sheeting (which is typically A.C, G.I sheets, or Mangalore tiles) are arranged over Angle Purlins and are then placed on top of the main rafters.
Couple roofs are usually used in areas in which it is necessary to limit the maximal span is restricted by 3.7 meters.
Advantages of Couple Roof
It is the most basic form of roof It can be utilized in garages and storage houses and also an residential structure with a narrow gaps between pillars. They are lightweight and simple to build.
If you have an appropriate slope, it is a great drainage solution to all kinds of residential structures. Also Read: Dynamic compaction of soil
4. Lean-to Roof
Lean-to-Roof can be described as the most straightforward version of the pitch roof with slope given on one side. In this kind of roof the angle to create a sloped roof is determined by the wall.
A wall on which the roof will be supported is elevated above the wall to which it is attached. This is what gives the slope or pitch.
On top of these walls the roofing material is laid down to create the appearance of a roofing lean-to. Usability: Outhouses, sheds and verandas connected to the main building. It's only able to be able to support an length of 2.4 meters since it's supported by a single side. Also Read: What is a topping slab
5. Couple Roof Truss
It is a new type of roof that is a lean-to roof. Here, the walls that the roof will be supported are maintained at the same height. Then, the roofing is installed that leans upwards toward each other.
In the middle, they meet with a horizontal beam, which is known as a"ridge. The pitched roof is allowed with a length of up to 3.6 meters. Also Read: Types of exterior wall finishes
6. Closed Couple Roof
It's akin to its couple roofing structure, except that it features an elongated tie beam connecting the legs of two rafters common to the wall supporting it.
It is referred to as a closed couple roof because it is the tie-beam that seals off the roof structure of the couple.
The presence of tie beams tie beam stops the rafters from stretching outwards. It also helps to prevent the overturning of walls that the roofing system is anchored. Also Read: Tie beam concrete
7. Collar Tie Roof
This is an altered version of the roof of a close couple. The collar tie roof is collar tie roofs the beam of tie that is installed at the base of the rafters in roof truss that is coupled is elevated above the ground and is called the collar beam.
The use of a collar beam allows that roofing structure to use the space efficiently. As the beam is raised, the size of the room will be increased. It is a good choice to cover a length of approximately 4.8 meters. Also Read: How does a beam bridge works
8. King Post Roof
Within this roof truss, the central post is inserted to join the ridgeline to that of the principal tie. This central post is also known as the King post.
The two rafters that are common that extend from the ridge to the eaves are referred to as the principal (main) rafters.
King Post helps support the ridge and holds the main rafters in place at the edge or apex on the highest point. It also supports its primary tie and keeps it from sagging. Also Read: Abutment on a bridge
Because this truss can be used to allow for larger lengths, there is a possibility that the rafter's main pillar could be bent from the middle. To avoid this the struts, which are inclined members, are installed.
Struts connect the middle of the main Rafter towards the center of the tie. It forms a joint with the King postand the other strut.
The majority of the time, king post roof truss is made of wood, but it could be a combination of steel and timber may be utilized. Utilizability Porch, sheds garage, small homes etc.
The King Post roof truss is a cost-effective option to an length of between 5-8 meters. Also Read: Cedar wood products
9. Queen Post Roof
This is a modified version of the King-post roofing truss. When the span grows this tie beam will begin to sag.
Instead of one post in the central point, The roofing truss for the queen post has 2 vertical posts that are horizontally aligned across the length.
The two posts that are vertical are known as "queen posts. The queen posts are set at a one-third distance away from support.
A horizontal piece of wood called the stretching beam connects the upper and lower sides of the queen post. It also helps to keep them in place.
A stretching sill connecting to the bottom of the queen post is set on top of the primary tie. This sill strains and prevents footings on the queen post from advancing closer. Also Read: Concrete frame
The inner square created from Queen posts and the straining beam can be braced diagonally in order to give some rigidity and strength to the truss.
Purlins are put in Queen posts in order to assist in the transfer of load. This is what makes it possible to make the Queen-post roof truss lighter than the roof truss of the king post. It could be utilized to cover a width of 8-12 meters.
