The kind of roof with downward slopes (commonly parted in the center) is termed as pitched roof. This roof is commonly found in houses. The types of pitched roof are very varied from 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 roof for the house, it is a perfect passage.

Different Types of Pitched Roofs
Here are the varying types of pitched roof. Some of them are usually applied in houses while several others might not.
This roof has simple structure which includes ridge beam and the rafters. Such roof structure is prone to experience spreading if not given lateral support. To prevent spreading due to wind uplift, collar tie is usually added to the structure. Unfortunately during renovation, many homeowners tend to take down the collar tie.
This roof also has 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 if compared to the previous one.
Just like its name suggests, this roof only has one downward slope. Houses tend to use this roof type to as an extension. Typically the placement is slightly lower than the main roof used in house structure. Sometimes, it is also used as basis to build clerestory windows for open areas in the house like hallways.
d. King post
Among many types of pitched roof with truss, this is perhaps the most classic one. It is built of two rafters which meet at the top side while its base is a tie beam which form triangle shape. There is a king post as a lateral support which goes from the center of apex to tie beam. This roof does not only offers strength but also allow lights to get in.
This roof has 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 is able to optimize the use of space underneath it. The space can be used as 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 purlin addition to 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 distributing loads to other supporting components.
Types of Pitched Roof Construction
When constructing varied types of pitched roof, there are two main approaches used. The first one is cut method and the second type is called truss. These days due to regulation related to building safety code, truss method is more common to be applied. What is the difference between the two methods?
In the cut roof method, 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. The downside of this method is related to safety because there is no way that the stresses can be measured without testing it beforehand.
Truss method is more approachable because the structure is already built in the manufacture. All you need to do are installing the roof on the intended spot and making sure to follow 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
