Rooftop Deck Construction
April 21, 2026
Ever Wondered if Your View Would Be Better From Your Roof?
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.

Why Choose a Rooftop Deck?
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.
Built for the PNW Environment
Rooftop decks require more than great design, they demand precision. Our team understands the importance of proper drainage by starting the foundation with a sleeper system for complete waterproofing and structural integrity. We only use code-compliant railing systems to ensure your deck is both safe and built to last.
We work with premium materials designed to withstand year-round weather exposure while maintaining a clean, modern appearance.

Material Options for Rooftop Decks
Choosing the right material for a rooftop deck is one of the most important parts of the project. The right system depends on how you want to use the space, the structure of the building, and the level of waterproofing and maintenance you prefer.
At 3 Brothers Decking, we offer both waterproof membrane systems and traditional deck surface options to create a rooftop space that fits your needs.

Gaco Waterproof Membrane Systems
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.
Composite and PVC Decking
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.
