Your Guide To Common Roofing Terms


Reading Time: 3 minutes

As a licensed roofing contractor, we are knowledgeable in common roofing terms. What we need to do is be able to explain these terms to homeowners in a way that they will understand.

Whether you are helping them with a re-roofing or roofing repair project, chances are that they will be stressed about it. An easy way to make them feel more comfortable would be to explain what you will be doing and why you will be doing it.

For this reason, Tag & Stick would like to go over some of the common roofing terms and what they entail.


A roofing system’s frame is the skeleton of the structure. It not only uses beams to create a strong shape, but it also creates a pitch in the roof the framing giving  the roofing cover positive drainage.

The framing consists of a number of elements, some of the most common being:


Rafters refer to the supportive framing that the roof deck is attached to. These wooden beams are placed at an angle to hold the roof deck while providing the main support for roofing covers. Rafters are often connected by crosswise beams.

Collar Beam

Normally, rafters and crosswise beams are used to create a triangle in the home’s roofing system. Collar beams, on the other hand, run horizontally through the structure. This allows them to both connect and support the rafters.

Generally, these beams will connect a pair of rafters halfway between the base and apex of the roof. This allows them to apply for lateral support, strengthening the overall structure of the system.


Most roofing systems have an overhang that extends past the side of the building. The eave refers to the underside of this overhang.

The eave allows water to run off the roof without damaging the side of the building.


The roof deck, also known as the roofing sheath, can be found directly above the framing. It’s now required to be minimum 5/8” thick plywood.

The roof deck connects the framing and secures everything in place. Not only that, but it also provides a stable surface for roofing materials to be applied.


Roofing underlayment options like Tag & Stick protect your roof from moisture and water damage. This layer can be found between the roof deck and roof covering.

Roof Coverings

A homeowner’s roof coverings will vary depending on the type of roof that they have and the style that they are looking for. These include all of the final layers that are added to the roofing system when creating a unique style, some of which are: Concrete Tile, Metal, Clay, Shingle.

Fastener Attachments

Fastener attachments are responsible for connecting the roof coverings and underlayment to the roof deck. They are made from a variety of materials, each designed with specific roof coverings in mind.

Roof Accessories

Ridge Cap

If you have a sloped roof, then you have a ridge cap. This is a fitted cap found where the two slopes of your roof meet.

They run horizontally so that they can protect the inside of your home while allowing heat and moisture to escape.


When roofing professionals talk about flashing, they are referring to material placed around the joints and angles on a roof. It’s designed to protect the ‘weak’ points in your systems from leaks and water damage.

It can be found anywhere that there is a protrusion from your roofing system like a chimney or vent. Helping to direct the water towards the gutters and downspouts prevents leaks from forming.

Roof Vent

Roof vents come in a variety of shapes and sizes. They are designed to allow warm air to be released from your roof, avoiding moisture damage.

Starter Strip

Homes with shingle roof coverings will have a starter strip. This is the first layer of shingles that lines the edge of your home’s roof.

The starter strip can be found beneath the underlayment to seal and waterproof the edges.

Drainage and Venting

Drainage and venting are two things that every homeowner needs to take seriously. A collection of moisture or water can have devastating effects on the integrity of a roof. Some of the important elements include:


A downspout ensures that water drains off the roof and into the correct spot. It is responsible for taking water away from the gutters and onto the ground.
