Anatomy of a Roof

Anatomy of a Roof

Most people do not think much about their roof as long as it works and looks perfect. Some people only know the different types of roofing because they consider it a mark of beauty for the home. All this is allowable because the exceptional roofer should make the roofing process easy and understandable.

What is the anatomy of a roof? Roofing is available in many different shapes, sizes, and components, so it does help to know more than the shingles, especially when you intend to repair or upgrade. We, however, do not mind breaking down the anatomy of a roof so you can identify the significant functioning parts and what they entail. The following is a simple rundown of all the technicalities.

The anatomy of a roof

What are the parts of a roof called? 


What is the basic structure of a roof? These are the foundation of the roof and form the peak of the entire structure. The truss is the wooden framework that supports the roof and will often go from the bottom to the top. A clearer perspective is the truss is the structure upon which all other materials rest.


The chimney is a well-known structure, which begins below the roofing structure, at the fireplace. It carries the smoke out of the cooking or fireplace area out through the roof.


The waterproof material is like a sealant between two different sections of the roof. It is the binding between the chimney and the roof, or two intersecting roofs. The flashing is one of the most accessible parts to repair because you have to reinforce the area with a new flashing to deter water entry. The thin metal sheet is standard around the following areas:

  • Valleys
  • Plumbing vents
  • Dormers
  • Skylights
  • Chimney
  • Vents like the attic, gable vent, soffit, and ridge


The structure is a thin material that is usually part of the asphalt shingle roofing. The water-resistant layer is installed directly under the shingle and adds extra durability, strength, and moisture protection against weather elements. It helps with drawing away water from snow and water, which means it should keep your shingle safe from all the excess moisture.


The shingles are what we see when we look at the roof from the outside. Most shingles have a range of colors and textures, which make up the home’s unique aesthetic. Let’s look at the most common types of shingles:

  • Asphalt shingles with 3-tab shingles, laminate or designer style
  • Metal shingles like aluminum, copper, steel, and alloy
  • Clay or concrete tiles
  • Composite shingles like rubber, plastic, and polymer

What are the layers of a house roof? All these shingles can take on a lot of different shapes, such as a traditional and straightforward style, dimensional style with multi-layered architecture, or luxury style with more than three tabs of layered shingles.


These are metal or vinyl pipes that draw water away through the gutter system. The structure and number of downsprouts will vary because it depends on the roofing architecture.

The above features are only a few of what makes up an entire roof. We are a certified roofing company that will be glad to analyze, diagnose and fix up your roof. Contact us for a roof inspection/assessment and quotation on metal roofing service or more.
