What Goes Under Roofing Shingles?

The roof is one of the most crucial components in the building and upkeep of a house or structure. It keeps those inside secure and comfortable and is the first defense against the elements. Because of this, it is crucial to understand the various components that make up a roof. Many homeowners and home builders like roofing shingles, but what is underneath?

Few things are more critical than the shingles on top of it. After all, they’re the first line of defense in protecting your home against the elements. But what goes underneath the shingles can be just as important. Depending on the type of shingle you choose and your environment, different materials may be necessary to ensure your roof can withstand the weather and keep your home safe.

Underlayment

The installation of underlayment is an essential step when laying down roofing shingles. After all, what good is a roof without a strong foundation? Underlayment creates a moisture barrier for your roofing system and adds an extra layer of security between your roofing material and the roofing deck. It aids in defending the roof from leaks, rain generated by the wind, and other environmental factors. Depending on the roofing material you’re using, it comes in a range of felt, synthetic materials, and rubber and can be applied in various methods.

Types of Underlayment

When it comes to your home’s roofing shingles, most people think of the colorful and visually appealing top layer that makes up most of the roof. But what is beneath the shingles, often forgotten or overlooked, is just as crucial to a safe, secure, and long-lasting roof. That is why it is vital to know the different types of underlayment that go under roofing shingles. There are several different types of roofing underlayment available on the market, including Synthetic underlayment, felt underlayment, Ice and water shield, and Self-adhering underlayment.

Proper Installation Techniques

Underlayment is essential to a roof’s construction, as it helps protect against water and ice damage. But more is needed to lay down the underlayment. It must be installed correctly to ensure a long-lasting roof.  The key to proper underlayment installation is proper preparation.

  • Select the Correct Type of Underlayment
  • Consider the Climate of the Installation Area
  • Use the Proper Nails and Nail Gun to Secure the Underlayment
  • Cut the Underlayment for Proper Fitment
  • Use Adhesive to Secure the Edges of the Underlayment

Ice and Water Shield

This is an essential part of protecting your roof against the elements and ensuring it looks great and lasts for years to come. Ice and water shield works as a barrier between your shingles and the elements, protecting against water infiltration and helping to prevent costly damage. As the temperatures drop, the ice and water shield will act as an extra layer of insulation, helping to keep your roof warm and preventing roof shingle damage caused by freezing.

  • Considerations to Make When Installing Ice and Water Shield: When installing an ice and water shield, it is vital to consider a few factors to ensure a successful installation. You will need to assess the size of the area you are covering. You must have enough material to cover the whole area and a few extra inches of overlap. It will help ensure your roof is properly sealed and protected from the elements.

You must ensure that your ice and water shield is installed correctly. Ensure you follow the manufacturer’s instructions carefully, as improper installation can lead to water damage.

  • Tips for a Successful Installation of Ice and Water Shield: If you plan to install an ice and water shield on your roof, measure the area where you plan to install the ice and water shield and cut the membrane accordingly. Be sure to check for any obstructions that might interfere with the installation. Before installation, inspect the roof for any signs of damage or deterioration. If there are any areas of concern, they should be repaired.

Roof Ventilation System

When it comes to roofing shingles, one thing you want to consider is a roof ventilation system. It is an essential part of the roofing process, as it helps to keep the air inside your home comfortable and breathable. It also helps to regulate the temperature inside, so your home stays cool in the summer and warm in the winter. Without an effective ventilation system, you may risk damage to your roof and the structure of your home. 

A roof ventilation system allows air to pass through a series of events installed along the roof’s peak. These vents allow hot air to escape through the top of the roof and pull in cooler air from the sides and bottom.

Felt Paper

When installing roofing shingles, it’s important to use felt paper as a base layer. Not only does it provide a protective barrier against moisture, but it also serves as a cushion between your home and the shingles. Felt paper is usually made of asphalt-saturated materials, such as fiberglass or polyester. This material helps keep the shingles in place while preventing water from passing through the roof. It’s essential to ensure the felt paper is installed correctly, as it will provide a stable foundation for the shingles and keep your roof in top condition for years to come.

Securing Roofing Shingles

Securing roofing shingles after the felt paper is in place is crucial in ensuring your roof is adequately protected. Once the felt paper has been securely fastened, it’s time to add the shingles. Nailing the shingles onto the roof is a delicate procedure that requires a steady hand and a sharp eye. Each shingle should be placed in a uniform pattern and firmly nailed. If the shingles aren’t correctly secured, they won’t be able to provide the best possible protection for your home, so it’s important to take your time and make sure each shingle is firmly secure.
