What Does Underlayment Do for Your Roof?

What is Underlayment?

Underlayment is the protective layer of your roof that sits underneath your shingles and directly on top of your roof deck. This protective layer is treated to be waterproof or water-resistant, giving your home an essential extra layer of protection against damp and rain. While there are several possible materials your underlayment could be made from, all of them fulfill the same basic functions, and the differences between them are less significant than in other roofing parts like shingles.

What Types of Material is Underlayment Usually Made of?

  • Asphalt-saturated felt, often referred to as “felt underlayment”
  • Non-bitumen synthetic materials, often referred to as “synthetic underlayment”
  • Rubberized asphalt

How Underlayment Protects Your Roof

While your shingles do a lot to protect your home, there’s always a chance that some water will sneak past them. Without underlayment, that moisture can keep collecting inside your roof until you’re dealing with mold, leaks, or other water-related issues. Underlayment ensures that any excess moisture in your roof doesn’t move any further than it already has.

Roof Underlayment Protects Your Home From:

  • Water damage
  • Mold growth
  • Excess moisture
  • Other types of weather damage

Know When Your Underlayment May Be in Danger

Damaged or degrading underlayer can spell disaster for your roof, so it’s important to ensure that your final layer of protection has its own protections intact. While it protects you from water, wind, and mold, your underlayment is vulnerable to heat and sunlight, and relies on the layers above it to keep it safe.

If you’re worried that your underlayment may be in danger, get your roof inspected by a professional. Licensed roofers know how important your underlayment is to the long-term safety of your home, and we’re trained to replace it quickly and efficiently if needed.
