The Basics of Residential Roofing

If you’ve ever wondered what goes into a residential roofing project, this quick video will walk you through the six basic layers of a new roof. Read on to learn about the six primary roofing layers.

High Performance Leak Barrier

It’s important to prevent any future leaks when completing a roofing project. This is generally included as the base layer in areas such as eaves and valleys to reinforce vulnerable areas of the roof with a leak barrier.

Roof Deck Protection

Traditionally, roof felt has been installed in this stage of the roofing process. However, roof felt can disintegrate with age and is less reliable than newer, higher-quality roof deck protection. This layer is essential to preventing any wind-driven rain or moisture from penetrating the roof below shingles.

Metal Drip Edge

This edge provides a clean, finished look to your new roof, but it also functions to drive water away from the roof and into your gutters.

Starter Strip

Shingle starter strips are designed to create a fully-sealed edge at the base of your new roof. This row of shingles will create a water-tight barrier for added leak protection.


This is the most recognizable step of any roofing project.

Roof Cap & Shingle

The roof cap is an extra barrier that’s placed over any peaks in your roof. This covers the vulnerable space between shingle rows on each side. A special roof cap shingle then completes the look.

There are, of course, variations to this process that are utilized in specialty roofing projects.
