Beautiful decking
Fine craftsmanship

I'm Tobin Marsh

and I design and build

pedestal-supported decks.

Working smart – start to finish –
I give as much attention to

the roof as to the deck.
 

My customers are thrilled with
the beauty, function and top-notch
quality of their finished decks.

Roof decks are a common element of Seattle's contemporary architecture, as outdoor living space increasingly expands onto "flat" rooftops. Such elevated decks are some of our most attractive gathering spaces, often providing stunning views of city and nature. Diverse material options and amenities invite us to design and craft the deck to compliment the beauty that surrounds it.

Modular deck tiles or pavers set over custom-fit pedestal supports are the key innovative materials that transform a low-slope rooftop into a functional oasis while providing the best possible protection to the roof itself.

This roof deck is an artistic combination of Cumaru wood tiles with 2CM porcelain pavers.

ROOF DECKS DONE RIGHT

Building a flat deck over a low-sloped roof can be tricky and few builders possess knowledge of the best materials and construction practices. It's not rocket science, but the details really do matter. 

​

A quality rooftop deck system can be conceived of as a three-dimensional, geometric, floating jigsaw puzzle composed of hundreds or thousands of individual components. The assembly is made up of surface pavers, pedestal supports and related components, shims, and protective slip sheets – each secured in its proper location and position. Additional materials are often needed to resolve irregular circumstances on the rooftop.  

​

Pedestal decking is a unique form of construction in that: 

  1. It's a level floor constructed over a sloped surface that must be judiciously protected.

  2. It's an assembly of modular decking units elevated and leveled over precisely-fitted pedestal supports.

  3. The deck "floats" – it's not anchored in place by common fasteners such as screws, bolts, nails, mortar, adhesives or welding.

​

The first principle of roof deck construction is that the roof itself must be respected and protected at every stage of design and construction. This is because even minor mistakes on a low-slope roof can result in potentially catastrophic water intrusion. In the proper channeling of water flow, small details really matter. 

​

Smart design and best construction practices result in a deck that is level, smooth and solid. It's handsomely contoured to perimeters and the gaps between pavers are consistent and tight. Pavers don't rock and there's no lateral shifting. The deck is gentle on the roof membrane beneath and does not impede water flow and drainage. The deck is beautiful and blends well with other details on the surrounding rooftop.  

This Capitol Hill roof deck shows a 2CM paver with a wood grain pattern.

A well designed and built deck remains
stable and beautiful for decades and is
a lifelong friend to the roof itself.

Quality means doing it right when no one is looking.

"Tobin’s attention to detail ensured that we had the right materials and tools

on the jobsite, and his precision ensured that I have a solid deck that will not shift. Working with Tobin gave me an appreciation of the intricacies in construction which are not obvious to the average contractor who does not specialize in floating deck systems. My deck pays dividends daily by being a well-constructed piece of art."

Roof decks are built into many modern homes
