Rooftop Deck Construction

A rooftop deck transforms a flat roof into a functional outdoor living space with unmatched views of the city skyline, surrounding mountains, or the Puget Sound. Whether it’s a private retreat for relaxing evenings or an elevated entertainment space for hosting friends and family, rooftop decks create a one-of-a-kind extension of your home.

At 3 Brothers Decking, we design and build rooftop decks that combine beauty, durability, and smart engineering. Every project is carefully planned to maximize your usable space while protecting the structure below. From modern waterproof decking systems to custom railings and sleek finishing details, we create rooftop spaces built to perform in the Pacific Northwest.

Maximize Unused Space

Flat rooftops often go underutilized. A rooftop deck allows you to take advantage of valuable square footage without expanding your home’s footprint.

Enjoy Elevated Views

Capture panoramic views of downtown skylines, mountain ranges, waterfront sunsets, and surrounding neighborhoods from the best seat in the house.

Increase Property Value

A professionally built rooftop deck adds both lifestyle value and long-term resale appeal, making your property stand out in a competitive market.

Create a Private Outdoor Escape

Above the noise of the street, rooftop decks offer a peaceful place to unwind, entertain, dine, or simply enjoy fresh air with added privacy.

For roofs where complete waterproof protection is the top priority, Gaco waterproof membrane systems provide a seamless, durable solution. These liquid-applied membranes create a fully waterproof surface designed to protect the structure below while still delivering a clean, finished appearance.

Gaco systems are ideal for:

• Walkable flat roof surfaces
• Waterproof rooftop patios
• Multi-family and commercial buildings
• Low-maintenance outdoor living spaces
• Long-term weather protection in the Pacific Northwest

This option is excellent for homeowners who want a sleek rooftop patio without the added height of a traditional framed deck system.

For homeowners looking for the feel of a traditional deck with elevated rooftop views, composite and PVC decking offers both beauty and performance. These systems are installed over properly designed rooftop framing and provide a finished outdoor living space with the warmth and style of a premium deck.

Benefits include:

• Low maintenance materials
• Fade, moisture, and rot resistance
• Modern colors and finishes
• Long-lasting durability
• Comfortable spaces for entertaining and relaxing

PVC decking is especially popular for rooftop applications because of its superior moisture resistance and long-term performance in wet climates.

Every home and building is different, which is why we tailor every rooftop deck to your specific vision and layout. Popular features include:

• Waterproof PVC decking systems
• Aluminum and glass railing systems
• Privacy walls and wind screens
• Outdoor kitchens and entertainment areas
• Built-in seating and lighting
• Pergolas and shade structures
• Modern low-maintenance finishes
