The roof with downward slopes (commonly parted in the center) is termed a pitched roof. This roof is commonly found in houses. The types of pitched roofs are very varied from a shape point of view. The construction processes, as well as materials used in building the rood, are also diverse. If you want to build such a roof for the house, it is a perfect passage.
Different Types of Pitched Roofs
Here are the varying types of a pitched roof. Some of them are usually applied in houses while several others might not.
This roof has a simple structure that includes a ridge beam and rafters. Such roof structure is prone to experience spreading if not given lateral support. To prevent spreading due to wind uplift, a collar tie is usually added to the structure. Unfortunately, during renovation, many homeowners tend to take down the collar tie.
This roof also has a simple structure: a ridge beam and rafters. One noticeable characteristic of this room is the absence of lateral support. This may lead to some less than desirable qualities, including roof spread. Because of this issue, it is less likely to find this roof type than the previous one.
Just like its name suggests, this roof only has one downward slope. Houses tend to use this roof type as an extension. Typically the placement is slightly lower than the main roof used in the house structure. Sometimes, it is also used to build clerestory windows for open areas in the house like hallways.
d. King post
Among many types of pitched roofs with a truss, this is perhaps the most classic one. It is built of two rafters that meet at the top side, while its base is a tie beam that forms a triangle shape. There is a king post as lateral support, which goes from the apex to the tie beam. This roof does not only offers strength but also allows lights to get in.
This roof has a unique shape because on each side (in total, it has four sides), there are two downward slopes. Typically the lower slopes will have steeper angles than the upper ones. This roof type can optimize the use of space underneath it. Space can be used as an attic room. The downside is its high cost both for installation and maintenance.
This is an improved version of the two classic ones: couple and collar roofs. The main difference is the purlin addition to the roof structure. Purlin is placed horizontally in the structure. It provides support to the weight from sheathing or roof deck. With its channel or W shape, this structural component helps to distribute loads to other supporting components.
Types of Pitched Roof Construction
When constructing varied types of a pitched roof, there are two main approaches used. The first one is the cut method, and the second type is called a truss. Due to regulations related to building safety codes, the truss method is more common to be applied. What is the difference between the two methods?
In the cut roof method, the process of constructing the roof occurs entirely on-site. Each roof component, such as rafter, joist, and other structural elements (purlin, collar, and hanger) is built on-site using timber. There might be adjustments made in the process depending on timber size.
This method’s downside is related to safety because there is no way that the stresses can be measured without testing them beforehand.
The truss method is more approachable because the structure is already built in the manufacture. All you need to do is installing the roof on the intended spot and following the instructions written on the package. This roof had been tested on the factory, and thus its risk assessment is more comprehensive than if using the cut roof construction method.
Types of Pitched Roof Coverings
What are the types of pitched roof covering available in the market? Let’s take a look at the following shortlist.
This covering requires expertise to assemble. However, it can accommodate varying types of roof structures.
Tiles can be made of concrete or ceramics. It is easier to install, but the homeowner needs to purchase the right tiles because each tile product might only cater to one roof.
It is usually installed to give off a unique industrial look. This covering is longer-lasting but requires plenty of expertise to install.
To install the roofing, certain skills must be owned. It might not last as long as the other coverings in the list, but it has a classic look.
Types of Pitched Roof Structures
Here is the list of what pitched roof is made of.
As you can see from the passage, there are numerous types of a pitched roof. The homeowner’s choice when it comes to constructing this structure largely depends on several factors: functionality, aesthetics, and location. It is important to consult with an expert about the perfect roofing for a house before making any important decision.
