The demand for synthetic roof underlayment is increasing. With the many benefits it can provide homeowners, it’s clear why this is the case. However, this doesn’t mean that it is the correct underlayment choice for you.
If you’re wondering about this, read on. This article will list and detail some pros and cons.
What Is a Synthetic Roof Underlayment?
Unlike felt types of underlayment, synthetic underlayment is newer on the scene. This is mostly because of the materials used to make it.
Felt has existed for several thousand years. However, inventors created plastics such as polythene and polypropylene in the 20th century.
Spun or woven forms of these materials make up synthetic types of underlayments. Beyond that, these differ from each other based on properties of thickness, exposure time, and damage resistance.
Pros of Synthetic Underlayments
One of the biggest advantages of synthetic over felt underlayments is weight. On average, synthetic roofing underlayment weighs less than the traditional felt style.
There are a few advantages to this. The first is that it’s easier to install. This makes it the best roof underlayment to use when you’re in a hurry.
The second is that it won’t place as much stress on a roof. Therefore, roofs with synthetic underlayments are less prone to collapse.
In addition, synthetic materials tear less easily than felt materials. This means that high winds are less likely to pull the former off the roof. Therefore, synthetic can be the best underlayment for areas with high winds.
Finally, a synthetic is more resistant to certain conditions than felt. It does not absorb moisture, so it is not vulnerable to growing mold. It can also become cold without getting damaged.
Cons of Synthetic Underlayments
One of the biggest disadvantages of synthetic roofing underlayments over felt ones is the cost. On average, the former costs a few cents more than the latter per square foot. While this isn’t a huge difference, this can add up.
Another issue has to do with the environment. Synthetic roofing underlayments are made of plastic compounds. Many environments have noted the negative effects that plastic has on the environment.
This is mostly because of plastic’s inability to break down quickly. It is also toxic. This can interrupt biological processes in many creatures.
Another consideration is that many roofers may not know how to install synthetic roof underlayments. Unlike felt underlayments, which need staples, these need cap nails or staples. If roofers use the wrong fasteners, it can affect the underlayment’s integrity.
