Baltimore Roofing: What is Roof Underlayment & Why is it Needed?

If you are thinking of changing your roof in Baltimore, we need to consider this. We often change our roof but forget to think about the materials beneath it. The roof deck, insulation, and roofing material itself all have their own specific functions, and one of the most important but often forgotten is roof underlayment.

What is Roof Underlayment?

Roofing underlayment means a layer of material situated beneath the roofing. It is chiefly put in place to shield against water infiltration and wind uplift. In addition, roof underlayment functions as a thermal break between the roof deck and the insulation.

There are a variety of different roof underlayment products on the market, but most are made from asphalt-saturated felt or synthetic materials. The type of roofing underlayment you choose will depend on the climate where you live and the type of roofing material you are using.

Roofing underlayment is typically installed in two layers. The first layer is installed directly on the roof deck and the second layer is installed over the first layer. The top layer should be at least three inches wider than the bottom layer to provide an adequate overlap.

Is Roof Underlayment Important?

Underlayment is an important part of your roofing system because it helps protect your home from water infiltration and wind uplift. In addition, underlayment serves as a thermal barrier between the roof deck and the insulation. It is important to install underlayment in accordance with the local building code and to inspect it periodically for damage or wear.

Roofing underlayment serves several important functions.

It protects the roof deck from water infiltration.

One of the most important functions of roofing underlayment is to protect the roof deck from water infiltration. If water penetrates the roof deck, it can damage the framing, insulation, and ceiling finishes. In addition, it can cause mold and mildew growth, which can lead to health problems. Roofing underlayment helps prevent this by creating a waterproof barrier between the roof deck and the roofing material.

It protects the roofing material from wind uplift.

Roofing underlayment also helps protect the roofing material from wind uplift. If the roofing material is not properly attached to the roof deck, it can be blown off in high winds. Roofing underlayment helps prevent this by providing a layer of protection between the roofing material and the roof deck.

It acts as a thermal barrier.

In addition to protecting against water infiltration and wind uplift, roofing underlayment also serves as a thermal barrier between the roof deck and the insulation. This helps prevent heat loss, which can save you money on your energy bills.

It provides a weatherproof barrier.

Roofing underlayment also helps protect the home from the elements. It forms a weatherproof barrier between the roofing material and the underlying structure, which helps keep out rain, snow, and ice.

If you are considering installing a new roof, be sure to include roofing underlayment as part of your project. A roofing company can help you choose the right type of underlayment for your home and install it correctly.

What Type of Roofing Underlayment Should I Use?

The type of roofing underlayment you should use depends on the climate where you live and the type of roofing material you are using. In general, you should use an asphalt-saturated felt underlayment in cold climates and a synthetic underlayment in warm climates.

Asphalt-saturated felt underlayment is made from a layer of asphalt-coated paper that is saturated with asphalt adhesive. This type of underlayment is ideal for cold climates because it can withstand extreme temperatures and is resistant to moisture.

Synthetic underlayment is made from a variety of materials, including polyethylene, vinyl, and fiberglass. This type of underlayment is ideal for warm climates because it does not absorb water and is resistant to UV radiation.

If you are unsure which type of roofing underlayment to use, consult a roofing contractor. They can help you choose the right product for your home and install it correctly.

How Do I Install Roofing Underlayment?

Roofing underlayment must be installed in accordance with the local building code. In most cases, it should be installed in two layers. The first layer should be a minimum of 15 lbs. per square foot and the second layer should be a minimum of 30 lbs. per square foot. The underlayment should also be installed in accordance with the manufacturer's recommendations.

The first step is to inspect the roof deck for damage and make any necessary repairs. Next, install a layer of roofing felt over the entire roof deck. Be sure to overlap the edges by at least six inches. Then, install the second layer of roofing felt in the same manner. Finally, install the roofing material according to the manufacturer's instructions.

It is important to remember that roofing underlayment is not a substitute for roofing material. It should only be used as a layer of protection between the roof deck and the roofing material.
