Denver Roofing Company Explains the Anatomy A Roof

October 4, 2017

Many people are familiar with common roofing materials such as asphalt shingles and slate tiles, but can you name any other part of your roofing system? Every homeowner should know the basics about their roof so they can easily communicate with professionals from a Denver roofing company when something is in need of repair.

What do you need to know? Here’s an overview of the different parts of a roof:


The roofing underlayment is found underneath the shingles and over the sheathing. If some of the shingles become loose or fall off, the underlayment will protect your home from water and other environmental elements. Without it, your home could potentially be exposed to these elements every time you lost a shingle.

Underlayment is almost always made out of felt, which is a type of material that is resistant to rain and wind. Homes are required to have a roofing underlayment, however older homes that were built before these regulations went into effect may not have one. Learn all about the roof structure and framing.


Sheathing is positioned on top of the roof’s rafters. This part of the roof is typically made out of plywood, however some homes have concrete, metal, or polystyrene sheathing instead. The sheathing plays an important role in keeping all of the different components of the roof in place. In fact, shingles are attached and held in place by the sheathing.

Roof Truss

The roof truss is often thought of as the skeleton or the foundation of the roof. It consists of various wooden beams, known as rafters, that run from the very top to the bottom of the roof.  


Flashing is made out of either steel or aluminum and is used to cover areas on your roof that are vulnerable to water damage. These strips of metal are durable, lightweight, and resistant to environmental elements, which is why they are so effective in preventing leaks. Flashing can be found on the joints of your roof and around the chimney and skylights since these are the areas where water is likely to seep into your home.


The highest part of the roof is known as the ridge. This is the area where two sloped sections of the roof join together. Many homeowners may think that this shape is created to make the roof more aesthetically pleasing, but it is actually designed this way to ensure that the roof is ventilated.
