Whether it is a repair, replacement or new installation, when you need roof services, you will need to speak with a roofer in South Jersey. Like every other profession, there are phrases and terms that are specific to roofing. Understanding some of the basic terminology and parts of roofing can help you better understand exactly what needs to be done. This can help you grasp timelines and the specifics of your project.

To help, we’ve put together a list of some important terms that you should know.

Decking/Sheathing: This is the base layer of your roof. Generally, plywood or oriented strand board (OSB) are used for decking/sheathing. This layer is what your roofing material is attached to.

Felt/Underlayment: Sometimes called tar paper, this is a paper layer between the decking and roof material. It adds a second layer of protection for your roof. 

Flashing: Pieces of metal that are used at the most vulnerable points in your roof. This extra layer prevents water from getting into the home. Flashing is used around projections like chimneys and vent pipes, as well as in valleys and joints on the roof.

Rafters: Rafters are part of the frame of the home and give the roof its shape. The decking is attached to the rafters, which provides the structure and support for the roof. 

Ridge: The ridge is the top edge of the roof. It is where two sloping roof surfaces meet.

Slope: The slope of the roof is determined by how much it rises in inches for each foot of horizontal run. 

Square: This is a common measurement for roofs. One square is equal to 100 square feet. 

Valley: Like a natural valley, a valley on a roof is found at the bottom of an intersection of two sloping surfaces.

Understanding these different basic roofing terms can help you during your roofing project. Not only will it help you understand exactly what is happening, but it will also help you better communicate with your South Jersey roofing contractor.
