The Parts of a Residential Roof

‍

What are the parts of a Roof?

A roof is more than just shingles, it has multiple parts that work together as a system. As a homeowner, it is helpful for you to understand the layers of your roof, in this article we will identify the common parts that make up a roofing system.

Decking– The first layer of your roof is the decking. Decking is the last layer of protection for your roof and acts as the foundation of the roof. The foundation of your roof is critical for a strong and long-lasting roof. Common types of sheet decking are OSB (Oriented Strand Board) and Plywood.

Underlayment– Underlayment is the next layer added to your roof. The underlayment is placed on top of the decking to protect against moisture in your roof. Without underlayment your shingles and decking could rot from moisture and mold buildup. Underlayment also acts as backup for damaged shingles and the first layer of protection for decking.

Ice and Water Barrier – This is a type a roof underlayment that sticks to decking. Its purpose is to protect your roof against water and ice damage. This type of underlayment is mostly used on low slope roofs that allow water or ice to sit on your roof. Homeowners in cold climates that experience heavy snow will need an ice and water shield to protect against sitting snow/ice.

Shingles– After the underlayment is laid, the shingles are nailed in. Shingles are your first line of defense. The shingles function as a shield for the rest of your roof. Also, shingles are important for your homes curb appeal. An attractive and healthy roof will drive the value of your home up.

Drip Edge- The drip edge is a metal flashing at the bottom of your roof intended to direct water off the roof and away from the fascia. Drip edge will help prevent water from seeping into your roof that can cause corrosion to your decking.

Flashing– Flashing is used to reinforce vulnerable areas of your roof. Areas where shingles meet but do not connect to protrusions are sealed off with flashing. For example, flashing is placed at the base of the chimney to close off the gap between your roof and the base of the chimney to stop water from getting through. Flashing is one of the most important components to roofing, without flashing a roofing system is vulnerable and will quickly fail.

Ridge Vent – The ridge vent runs along the peak of your roof where two planes meet. Its purpose is to release hot air through the top your roof. If hot air sits in your attic, moisture will build up, causing your wood to weaken and mold will grow.

Soffit Vent – Soffit vents are in the eaves, which is the area at the bottom of your roof that extends past your walls. The purpose of this vent is to allow fresh air to flow into the roof. Soffit vents are often paired with other vents, usually ridge vents, to make sure air is flowing through the attic. Ventilation helps control the temperature in your attic which in turn will allow you to control the temperature of your home as well.
