Know the Layers of Your Shingle Roof

When it comes to a new roof, most people think of the shingle, the exterior layer. While this is a very important element to a protective roof, there are many other essential components to a solid roofing system.

Roof Deckprotective roof

This 1st layer is the layer that the rest of your roof is laid on. When it comes time for a new roof, it is important to strip the top layers of materials to reveal the roof deck below. Any signs of moisture, rot, or mold in the deck should be addressed. The bottom layer is most often wood planking on residential homes.

Ice and Water Barrier

Designed to protect the roof where water tends to collect, including valleys and eves. These areas are most prone to leakage with water runoff and ice damning occurring along the valleys and eaves of the roof. The leak barrier gives added protection where it’s needed most. This helps prevent long term damage from the Colorado weather allowing the proper flow of water off the roof.

Roof Deck Protection

Also known as underlayment or roof felt, this layer of protection is the crucial final line of defense between the home and the outer shingles. This synthetic underlayment or felt material, provides a strong barrier to wind, rain, snow, and ice. Preventing rot, mold and water damage.

Starter Shingles

Installed along the perimeter of the roof, starter shingles have a sealant strip that reinforces the more vulnerable edges and eaves. These areas are most prone to wind and water damage and the starter strip gives added protection with the final layer of shingles on top.


This is the final outer layer of defense against the elements and one of the most prominent aesthetic features of any home. Shingles range in color, size, and type of material with various classifications of protection available. A class 4 shingle is the highest rated shingle for impact resistance and is used in places with high winds and violent hail storms.

Ridge Vent and Cap

The ridge vent is designed to allow excess heat and moisture from within the home to escape while still protecting from the outside elements. Unique ridge cap shingles are installed over the ridge vent to complete the roofing system. They provide a finished look while defending the ridge vents.
