We rely on our roofs to keep us safe from what’s happening outside. Whether its our bright Colorado sun, our random hailstorms or the mountains of snow we (sometimes) get during the winter, the perfect roof can protect you no matter what the season. Here at Colorado Superior Roofing, your local Lakewood roofers, we know how to match each roof with the families that need them. Even still, it’s important for every homeowner to know the components of their roof and why it works as well as it does. The article below offers some tips on learning about roof underlayments and how they help roofs do their jobs:
What is roofing underlayment, and why do you need it?
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
- Non-bitumen synthetic underlayment. This is also known as “synthetic underlayment.”
- Rubberized asphalt underlayment
Asphalt-saturated felt and synthetic underlayment are water-resistant. Rubberized asphalt underlayment is waterproof.
Why do you need roofing underlayment?
It’s a moisture barrier.
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 roofing underlayerment
Water-resistant underlayment is enough for the surfaces of most roofs. It provides the protection that your roof needs during and after installation.
Even without the added protection of shingles, a superior product can withstand some seriously extreme weather.
