Your roof protects your home from the elements. Pretty basic stuff, right? Less obvious are the parts that go into the whole roof system. Maybe you’ve never heard of roofing underlayment. It’s doing a lot of work for you every day.
Roofing underlayment is a water-resistant or waterproof barrier material that is installed directly onto your roof deck. It is applied under all other roofing materials as an added layer of protection from severe weather.
There are three main types of roofing underlayment:
Asphalt-saturated felt and synthetic underlayment are water-resistant. Rubberized asphalt underlayment is waterproof.
Asphalt-saturated felt was the go-to roofing underlayment until about 15 years ago. That’s when synthetic products started gaining in popularity.
Synthetic underlayment (technically non-bitumen synthetic underlayment) is the preferred underlayment of most roofing professionals today.
Rubberized asphalt is more expensive than other types pf roofing underlayment. Why? It contains higher percentages of asphalt and rubber polymers, making it waterproof.
Roofing underlayment provides your roof with an extra layer of protection that shingles alone can’t match.
Your shingles serve their own purpose: they’re the first line of defense. Shingles reflect the sun’s rays, withstand wind and block precipitation.
But shingles overlap and aren’t sealed at all corners. They can be lifted by strong winds. This makes shingles vulnerable to tear-off or infiltration by wind-driven rain. Shingles can become brittle from ag. The heat of an unventilated attic can cook your shingles, too.
Water-resistant underlayment is enough for the surfaces of most roofs. It provides the protection that your roof needs during and after installation.
