There’s so much more to your roofing system than the shingles. One important roofing component you need to know is the underlayment. Although it is a hidden part of your roof, it plays a major role in keeping your home’s structural integrity stable and strong.
NC Rebuild, Inc., your trusted residential gutter installation services provider, explains why it’s best to have an underlayment as an extra layer of protection.
Why Does Your Roof Need an Underlayment?
As the name suggests, the roofing underlayment is installed under all the other roofing materials. It’s a waterproof barrier that provides an additional layer of protection from moisture and the other elements Expert roofers make sure to install one to ensure the entire roofing system remains in good condition.
In the event the top layer of your roofing material suffers a leak, the underlayment keeps your roof decking dry and safe. Without it, moisture can seep into your roof deck and lead to issues such as rot and mold. If you notice your roof leaking, you will need to contact a residential roof repair professional.
What Are the Different Types of Roof Underlayment?
In general, the roofing underlayment comes in three types: asphalt-saturated, non-bitumen synthetic, and rubberized asphalt.
Asphalt-Saturated – Although synthetic products replaced it as the top roofing underlayment choice, asphalt-saturated remains to be a durable underlayment material. It’s applied across the entire roof deck and has a base mat or a flexible base layer that is saturated with asphalt for water resistance. Asphalt-saturated also comes in different thicknesses with varying resistances to damage and weather exposure.
Non-Bitumen Synthetic – For most roofing experts, non-bitumen synthetic is the ideal underlayment. Like asphalt-saturated, this underlayment is saturated in asphalt but added with fiberglass for extra stability and tear resistance. One major advantage when it comes to non-bitumen synthetic underlayment is that it is a light, effective water barrier, which means you don’t have to add a lot of weight to your roof.
Rubberized Asphalt – While it’s the most expensive option among the three, rubberized asphalt has all the advantages of the two other underlayments and more. It contains higher percentages of asphalt and rubber polymers, essentially making it waterproof. Rubberized asphalt has a sticky back with a protective membrane. Take note that this special sticky backing creates a “natural” waterproof seal between it and the roof deck. Not only that, but this underlayment also provides more heat and cold resistance than asphalt-saturated felt.
