Roof Underlayment: Your Auburn Home's Critical Defense Against Heavy Rain
•

Diamond Roofers LLP

Why Roof Underlayment Matters in Auburn's Rainy Climate
In Auburn, Washington, where annual rainfall significantly exceeds the national average, your roof faces constant challenges from moisture. While shingles and other roofing materials provide the visible protection for your home, it's the underlayment beneath that often determines whether your roof truly keeps water out or allows costly leaks to develop.
What Is Roof Underlayment?
Roof underlayment is the protective layer installed directly on your roof deck, beneath your shingles or other roofing materials. Think of it as your roof's last line of defense—when water makes it past your primary roofing material, quality underlayment prevents it from reaching your home's structure.
For Auburn homeowners, proper underlayment isn't just recommended—it's essential for protecting your property investment.
Types of Roof Underlayment for Auburn's Weather Conditions
Felt Underlayment
Traditional felt underlayment (sometimes called tar paper) has been used for decades. While economical, it offers:
- Basic water resistance
- Shorter lifespan in high-moisture environments
- Less protection during installation periods
Synthetic Underlayment
Modern synthetic underlayments provide superior protection for Auburn homes:
- Enhanced water resistance
- Greater durability during installation
- Longer lifespan in our rainy conditions
- Better tear resistance during high winds
Rubberized Asphalt Underlayment
For maximum protection in Auburn's rain-heavy climate:
- Self-sealing around nail penetrations
- Waterproof (not just water-resistant)
- Ideal for roof valleys and other high-water areas
- Extended protection against ice and water
Signs Your Auburn Home Needs New Underlayment
- Water stains on ceilings or walls
- Mold or mildew in your attic
- Increased energy bills (due to compromised insulation from water damage)
- Visible roof deck deterioration
- Shingle damage that may have compromised the underlayment below
