Seattle’s Rooftop Deck Experts – Built for Beauty, Built to Last

Bring Your Rooftop Deck Dreams to Life

A rooftop deck isn’t just an upgrade — it’s a transformation. Whether you're dreaming of skyline views or a quiet escape above the city, we bring that vision to life with precision, passion, and nerd-level know-how. We don’t just install rooftop decks, we engineer them to perform in Seattle’s toughest weather.

When Style Comes Before Structure, Homeowners Pay the Price

We’ve seen it too many times: beautiful rooftop decks that turn into expensive headaches. Built by contractors who don’t understand roofing science, these decks leak, sag, or cause structural damage — sometimes just months after installation.

Seattle’s wet climate makes things even riskier. A small drainage issue can lead to mold, rot, and serious roof damage. And once water gets in? It’s already too late. That’s why rooftop decks should only be built by specialists who live and breathe roofing.

Seattle’s Only Roofing Nerds with a Deck Obsession

We approach rooftop decks differently because we’re not deck guys who dabble in roofing. We’re roofers who obsess over decks. Every project starts with the roof structure itself: we inspect, calculate load requirements, and waterproof with military-grade precision.

Then comes the fun part: building an outdoor space that’s not just stunning, but smart. From slip-resistant surfaces to pedestal systems that protect your membrane, every choice we make is intentional and informed. We design with Seattle’s weather in mind, so your deck stays dry, safe, and solid for years.

We don’t cut corners. We geek out on details. That’s the difference.

How Much Does a Rooftop Deck Cost in Seatlle?

Rooftop decks are big projects. You want to take the time to make sure your roof is safe and protected from water damage. These steps mean higher costs. Here's an overview of what you can expect to pay as a Seattle area homeowner:

Installation: Rooftop decks in Seattle typically range from $40,000 to $80,000. This range will change depending on factors like the rooftop deck materials you choose and design complexity. Reinforcing and waterproofing the roof is a big chunk of this cost.

Materials: Options like walkable membranes cost around $10–$15 per sq. ft., while tiles or pavers on pedestals can be $60–$100 per tile, plus pedestal costs. You'll also need railing, which can range from $60 to $400 per linear foot to install (depending on the material your choose).

What happens if I skip some steps to make my rooftop deck more affordable?

Common repair costs range between $30,000 and $50,000, depending on the issue's severity. Poor installation or waterproofing can lead to leaks or other issues. Most repairs we do are from leaks that have gone unnoticed and caused extensive damage.

"They were detail oriented ensuring the roof and garage were replaced/ built well. They cleaned up daily when they were through. They addressed concerns as I had them. Nestor and Omar and the whole RoofSmart team were outstanding! I'd highly recommend them to family and friends. I love my new roof and garage!"

Dan S.

"RoofSmart inspected the roof defects and explained everything thoroughly. They provided a copy of the inspection report, complete with the photos of the defects and regulations which the defects didn't meet. They are kind, professional, and skilled. Couldn't ask for more. Highly recommended."

Calvin P.

"They did an excellent job from the estimate through the completion of the new roof and new gutters with downspouts. The new roof looks much better and, most importantly, it will last decades. I highly recommend RoofSmart. They are professional, meticulous, friendly and they do the job right. Thanks, RoofSmart!"
