Charleston Roofing: Article About Roof Framing
Your roof is one of the most important structural components of your home. However, in addition to providing protection for you and your family, your roof also plays a huge role in your home's aesthetics. What you may not know is just how much goes into the design and building of your roof. At the base of it all is the framing. While your professional Charleston roofing contractors will take care of the work, it is always beneficial to know just how your roof is built.
The first thing that your contractor will do is design the overall layout of your roof. This includes determining what the angle of the slope will be and the overall size of the roof. Additionally, the type of roof and whether there will be valleys, hips and dormers must be determined.
Next, the number of trusses that will support the other components of the roof need to be determined. The amount of weight that each truss can support depends on a number of factors, including how deep or shallow the truss is and the roofing materials that are going to be used. These factors, in addition to the size of the structure, will also determine how many trusses will be needed. The trusses will also determine the pitch of the roof, which will be different depending upon your home's aesthetics and the environment.
Next, the placement of each rafter is marked out on each truss.

Rafters are generally placed 2 feet from each other, though this may vary depending upon the structure design. Each truss is then lifted onto the top of the structure. Once all trusses have been lifted, they are put into position and secured.
Once all of the trusses have been secured, other roof elements are added to the trusses. For example, gables end overhangs are then built before being installed. These overhangs not only contribute to your home's overall design, but they also serve a functional purpose. In all climates, they can help shade the windows from the sun and protect the sides of your home against water.
The next step is to install any sub-fascia board that may be part of the roof's design. Once this is done, the sheathing or decking is placed over the trusses and rafters, starting at the bottom and working upwards. Once all of the sheathing has been laid down, all exposed wood is covered in builder's felt. This protects the roof against the elements.
Finally, the last major component to be installed on your roof is the shingles or other roofing material of your choice. Like the builder's felt, the outermost material's purpose is to keep moisture and rainwater out and to keep the substructure safe from hail, snow and other potential damage.
