Seattle Flat Roof

Waterproof protection. Energy efficiency. Lasting value.

Flat and low-slope roofs require specialized materials and expert installation. At Roof Boss, we provide professional Seattle flat roof replacement services using premium membrane roofing systems designed for long-term protection and performance.

Our team serves both residential and commercial properties, offering durable solutions that stand up to Seattle’s rain-heavy climate.

Why Replace Your Flat Roof

A flat roof that’s aging, leaking, or pooling water can quickly lead to interior damage. Upgrading to a new membrane system provides:

• Seamless Waterproofing: Prevents leaks and ponding water.
• Energy Efficiency: Reflective surfaces lower heat absorption.
• Low Maintenance: Minimal upkeep required.
• Durability: Resistant to weather, UV, and chemicals.
• Cost Savings: Long lifespan and reduced repair needs.

Whether you need TPO or PVC, Roof Boss helps you choose the right system for your property and budget.

Our Flat Roof Replacement Process

1. Assessment & Estimate – We inspect your roof for damage and drainage issues.
2. Surface Preparation – Old materials are removed and the structure prepped for adhesion.
3. Membrane Installation – We install and heat-seal the new membrane for watertight protection.
4. Final Inspection – Every seam and drain is checked for perfect performance.
