Flat Roofing Kent | TPO, PVC & Torch Down Installers

Flat and low-slope roofs require a completely different skill set than shingle systems. When installed incorrectly, flat roofs don't fail slowly, they leak immediately. We install and repair flat roofing for residential and commercial properties across Kent, including commercial roofing throughout the Valley - from home additions and carports to warehouse and retail buildings - with a focus on leak prevention and Pacific Northwest performance.

The Challenge of Flat Roofs in the Pacific Northwest

Flat roofs lack the water-shedding capability of pitched systems. In Kent, rainwater often sits on flat surfaces during winter, creating standing water that stresses seams, penetrations, and drains.

Common issues we see include:

• Ponding water during Kent winters
• Failed seams allowing slow water intrusion
• Clogged scuppers and drains
• Wet insulation trapped beneath the membrane

A successful flat roofing system must be fully waterproof, not just water resistant. That means welded seams, proper drainage design, and attention to every detail.

Our Flat Roofing Systems

TPO & PVC Single-Ply Roofing

TPO (Thermoplastic Polyolefin) and PVC roofing systems are modern single-ply membranes commonly used on residential additions and commercial flat roofs.

• Heat-welded seams for waterproof integrity
• Reflective white surface for energy savings
• Available in 60-mil thickness for durability
• Resistant to UV exposure and chemical breakdown

These systems are ideal for property owners seeking energy efficiency and long-term performance.

Torch Down (Modified Bitumen) Roofing

Torch Down roofing is a multi-layer system that has been used successfully for decades on flat and low-slope roofs.

• Durable, reinforced membrane layers
• Excellent resistance to foot traffic
• Strong performance in wet conditions

Torch Down remains a reliable option for carports, garages, and certain commercial flat roofs.

Residential Flat Roofing (Carports & Patios)

Homeowners often overlook flat roof sections on carports, patio covers, and home additions. When these areas leak, water can travel into walls and compromise the main roof structure. We install flat roofing systems designed to protect these vulnerable areas.

Repair vs. Replace for Flat Roofs

Flat roofs are more complex to repair than sloped roofs. If water has soaked into the insulation, replacement may be the only reliable option. We use core cuts to assess insulation condition, and localized damage like punctures or seam failures may qualify for flat roof repair. Our recommendations are based on condition, not upselling.

Certified Flat Roof Installation

Proper flat roof installation depends on precision and experience.

• Mechanical attachment or full adhesion based on system design
• Proper slope and drainage planning
• Sealing all penetrations, pipes, and vents
• Careful installation of scuppers and drains

Most flat roof failures begin at the details. We focus on sealing those details correctly the first time.
