When building a roof, it is important to understand how the “pitch” of the angle of the roof functions. The vast majority of homes are dramatically pitched. Even when a roof appears to be flat, there is still a slight angle to it. Here is a little information about roofs concerning pitches and framing:
Four Basic Roof Types
There are about four basic pitched roofs: gabled, hipped, shed, and mansard. Perhaps the most common of them all, the gabled roof, is most easily recognized for its triangular shape. Gabled roofs are excellent choices in areas with heavy snow or rainfall, because water and snow slides off with easy. Gabled roofs also allow for good ventilation in the home.
These roofs however are not recommended for areas that have frequent high winds or hurricanes. This is because it tends to be weaker in structure, and it will possibly collapse in on the home.
Another popular roof is the hipped roof. Hipped roofs have four equal sloped sides,that join together to form a ridge at the top. These roofs are more durable than most, and certainly more stable than gabled roofs. However, due to the complexity of its structure and more materials needed it is more expensive to construct.
The shed roof has only one slope. This type of roof is not normally used for the entire home. Most of the time,the shed roof is used when it is necessary or desired to build an add on to the home. However, it is not unheard of to have a shed roof for your home. Shed roofs are sometimes used to roof the entire house, and it is an attractive and quirkier choice. Though take into consideration that if the roof is pitched too high, one side of the home is at risk of having an uncomfortably low ceiling.
A mansard roof has four sloped sides that form another roof shape on bottom. These roofs can contain another living quarter or a large attic, which adds value to your home. These roofs are not ideal for regions that experience heavy snowfall however, as it will pile up.
Stick & Truss Framing
Moving onto frames, there are two methods usually used to build the frame of your home. One is called a “stick”frame. The other is called the “truss” frame.
When using a stick frame, every piece of the roof is built while at and on the construction site. Each of these pieces are stuck together piece by piece, therefore earning the name “stick” frame as it is quite literally stuck together.
The truss frame is a tad more complicated, though normally more sturdy and can handle heavier and more lumber. Before ever coming to the construction site, a truss is built, which pre-determines what the pitch of the building will be. Attached to the trusses is the ridge beam, which runs down the home long ways at the peak of the pitch.The rafters meet at the ridge beam to help support the pitch of the home.
The framing of the roof depends on the structure and the material used to roof the house. Be sure to choose a reputable contractor to construct your home!
