Synthetic Underlayment Is Now Safer

Some types of synthetic underlayment actually gets a little tacky when wet. Improved walkability alone is the reason many roofing contractors have made the switch from felt.

What Is Asphalt Felt / Tar Paper Underlayment

Asphalt felt underlayment is known by many different names, including felt paper, roofing tar paper, felt underlayment, asphalt-soaked felt, and so on. For this article, we will just call it felt underlayment or felt paper. Felt underlayment is an all-over roofing accessory made of a natural or synthetic base that is then saturated in asphalt to make it waterproof. It is then laid down and attached to the roof deck below the roofing material.

Felt was widely used in the mid-to-late 1900s as the preferred underlayment choice but is slowly phasing out due to the introduction of better synthetic options. However, it is still used today in some steep-slope and shingle applications.

In general, the asphalt-saturated felt is utilized for residential applications where a steep slope is present. Each type of underlayment serves its own purpose and a roofing expert will know which one is right for your home. All will offer high levels of protection against moisture and have varying degrees of fire resistance.

Synthetic Roof UnderlaymentWhile asphalt roofing felt was the standard for decades, synthetic roofing underlayment is a very popular choice. There are several manufacturers available on the market, including Owens Corning, Tyvek, RhinoRoof, and more. They are lighter than other underlayments, have a high tear strength, and are considered waterproof instead of water-resistant.

A high-performance synthetic roof underlayment will also have some non-skid properties that help during installation. They are resistant to UV rays and can be exposed to the weather for months on end without deteriorating. As with any underlayment, synthetic underlayment is at its most effective when installed correctly, especially at the edges.

Roofing FeltThere are two standard types of asphalt-saturated felt underlayment: 15 and 30 felt. This refers to the weight of the felt over one roofing square, which is 100 square feet. If youre using 15 felt, that means a roofing square will weigh 15 pounds. The 30 felt material is much stronger and will stand up to the elements much better.

Roof paper types

While many homeowners pay attention to the top layer of the roof where the shingles reside, there is another, unseen layer just beneath, with a very important job: This is the roofing underlayment, and it protects your roof against moisture and heat damage.

What is an underlayment?

An underlayment is a barrier that is placed down on a roof before the top layer such as shingles or tiles is installed. It is placed, usually through adhesives, against the roof decking and provides an extra layer of protection. You see, while shingles and other top layer materials do a good job at protecting the roof from some elements, they struggle to prevent certain problems with seeping moisture or heat buildup.

The underlayment, however, can deal with these more insidious problems. It keeps water away from the roof decking if any leaks beneath the top layer especially leaks that carry chemical traces to and from shingles, which can be especially corrosive to the shingles and the decking alike. The underlayment also insulates the roof and attic spaces from heat. It can even add some sound insulation against falling rain and other noises.

There are two common choices when it comes to a roofing underlayment:

Matching the underlayment to your roof

Climate is also an important factor. Hotter climates or very wet areas may be more conducive to synthetic underlayments, but if you live in location that receives frequent snow and windstorms, heavy-duty felt may be preferable.

How Are Solar Panels Attached To A Shingle Roof

Panels are fastened to rails with specially designed clips that bolt to the edges. They allow the panels to be swiftly and easily removed for roof repair when necessary.

To form a string, electrical wires behind each panel are linked to the adjacent panel. The panels are now interconnected, making removing or installing any single panel easy.

The panels must be angled at about 30 degrees for proper orientation. They are also installed in order from the ridge toward the eave.

The back edge of each panel gets a metal clip attached to its bottom edge before being fastened to rails and the metal support structure behind them. The clips will be anchors for tightening the connectors later on with screws.

This step isnt necessary if panels are installed on a roof that already has supports for mounting them . If so, simply orient each panel and use clips and screws to secure them on the rails running below.

How To Choose The Right Roof Underlayment

So, how should you go about selecting a roofing underlayment? There are several factors at work, but the type of top layer used on your roof is one of the most important.

Roofing felt typically goes perfectly with traditional shinglesmainly the 15-pound roofing felt that provides sufficient protection while still allowing air to move around. However, if your roof is metal, you may want to use a heat-resistant synthetic layer, as metal roofing easily retains heat compared to other materials.

Climate is also a crucial factor. For example, synthetic underlayment may be better suited to hotter climates or very wet regions. On the other hand, heavy-duty felt may be beneficial if you live in an area prone to windstorms and snow.

Choosing the best underlayment for your roof requires technical knowledge. There are many things to consider aside from the factors that have been mentioned, and this could get complicated if you are not a roofing expert. However, as licensed roofers, we are here to help you decide which type of underlayment is best suited for your roof.

Felt that is saturated in asphalt is water-resistant for a while, but it will wear down eventually and become penetrable. When more asphalt is used for saturating the material, that makes the underlayment more durable but also more expensive. When it comes to the roofing process, asphalt is the component that is the most expensive. Lower priced underlayment will be of lesser quality and contain less asphalt potentially.

Why Roof Underlayment Is Important

Many areas require roofing underlayment. It is essential as it works as a moisture barrier, keeping your roof safe from rain and other harsh weather.

It provides your roof with an added layer of protection, supporting the work of your shingles. The underlayment and shingles are your home’s first line of defense from harmful elements caused by harsh weather conditions. In addition, they reflect the rays from the sun, block precipitation, and withstand wind.

However, shingles overlap and are not sealed at all corners. As a result, strong winds can lift the shingles, making them vulnerable to infiltration or tear-off by wind-driven rain. Shingles also become brittle as they age. Underlayment is the backup protection when shingles fail.
